[0059] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0060] The following is a detailed description of a glass film tactile metal card having high hardness and high gloss characteristics and a method for manufacturing the same according to a preferred embodiment of the present invention, with reference to the attached drawings.

[0061]

[0062] General metal cards are manufactured using direct printing, direct color pattern forming, film lamination, thermal transfer, and metal deposition methods.

[0063] FIG. 1 is a cross-sectional view showing a general metal card according to the first example.

[0064] As illustrated in FIG. 1, a general metal card (10) according to the first example exhibits a direct printing method in which a printing layer (14) is directly printed on the upper surface of a metal sheet (12).

[0065] Here, the metal sheet (12) can be formed from stainless steel or aluminum.

[0066] In addition, the printed layer (14) can be formed by printing a decorative pattern, color, text, etc. directly on the surface of the metal sheet (12) with tint (translucent) or opaque ink.

[0067] The general metal card (10) according to the first example described above has a structure in which a printed layer (14) is directly formed on a metal sheet (12), so the process is simple and has the advantage of maintaining a metallic texture.

[0068] However, the general metal card (10) according to the first example can only achieve a monotonous decorative effect and it is difficult to express color. In addition, the general metal card (10) according to the first example has a high risk that the printing layer (14) is easily damaged and is very susceptible to surface scratches, so there is a risk that scratches will occur on the metal sheet (12) and the surface will be easily contaminated.

[0069]

[0070] FIG. 2 is a cross-sectional view showing a general metal card according to the second example.

[0071] As shown in FIG. 2, a general metal card (20) according to the second example represents a direct color pattern forming method in which a UV printing layer (24) is directly printed on the upper surface of a metal sheet (22).

[0072] Here, the metal sheet (22) can be formed from stainless steel or aluminum.

[0073] In addition, the UV printing layer (24) can be manufactured by using a dedicated color UV paint and dedicated equipment to form the desired color and pattern directly on the surface of the metal sheet (22) in a single process using a color UV paint.

[0074] The general metal card (20) according to the second example described above has a structure in which a UV printing layer (24) is directly formed on a metal sheet (22), so the process is simple, the metallic texture can be maintained, and the color can be easily expressed.

[0075] However, the general metal card (20) according to the second example has limited color and decorative expression, and the UV printing layer (24) is exposed to the outside, so there is a high risk of it being easily damaged by external impact. In addition, the general metal card (20) according to the second example has the problem that the UV printing layer (24) is exposed to the outside, so it is easily contaminated and very vulnerable to surface scratches.

[0076]

[0077] Figure 3 is a cross-sectional view showing a typical metal card according to the third example.

[0078] As illustrated in FIG. 3, a general metal card (30) according to the third example shows a film lamination method in which a printing layer (35) is formed on the lower surface of a thin film (36), a UV printing layer (34) and a deposition layer (33) are formed sequentially on the lower surface of the printing layer (35), and then the thin film (36) having the printing layer (35), UV printing layer (34), and deposition layer (33) formed thereon is laminated through a metal sheet (31) and a bonding member (32).

[0079] Here, the metal sheet (31) can be formed of stainless steel or aluminum.

[0080] The thin film (36) is a film used as a substrate, and PET, PC, PVC, TPU film, etc. can be used.

[0081] In addition, the printed layer (35) can be formed by printing a decorative pattern, color, text, etc. directly on the surface of the metal sheet (31) with tint (translucent) or opaque ink.

[0082] The UV printing layer (34) is a layer that forms a three-dimensional pattern, and usually a UV three-dimensional pattern is formed using a UV pattern molding machine with a transparent UV paint and a pattern mold.

[0083] The deposition layer (33) is a layer formed by vacuum deposition to serve as a reflector for the pattern, and the deposition specifications, such as silver, color, or transparent, can be determined according to the required decoration (design) specifications.

[0084] The general metal card (30) according to the third example described above is capable of expressing various colors and three-dimensional patterns, can maintain a metallic texture, and is resistant to external impact because the printing layer (35) is protected by a thin film (36).

[0085] However, the general metal card (30) according to the third example has a complex process, a somewhat high manufacturing cost, concerns regarding reliability issues such as interlayer delamination, and is vulnerable to surface scratches.

[0086]

[0087] FIG. 4 is a cross-sectional view showing a general metal card according to the fourth example.

[0088] As illustrated in FIG. 4, a general metal card (40) according to the fourth example shows a film lamination method in which a printing layer (43) is formed on the lower surface of a thin film (44), a UV printing layer (45) is formed on the upper surface of a thin film (44), and then the thin film (44) having the printing layer (43) and the UV printing layer (45) formed thereon is laminated through a metal sheet (41) and a bonding member (42).

[0089] Here, the metal sheet (41) can be formed from stainless steel or aluminum.

[0090] The thin film (44) is a film used as a substrate, and PET, PC, PVC, TPU film, etc. can be used.

[0091] In addition, the printed layer (43) can be formed by printing a decorative pattern, color, text, etc. directly on the surface of the metal sheet (41) with tint (translucent) or opaque ink.

[0092] The UV printing layer (45) is a layer that forms a three-dimensional pattern, and usually a UV three-dimensional pattern is formed using a UV pattern molding machine with a transparent UV paint and a pattern mold.

[0093] The general metal card (40) according to the fourth example described above has a relatively simple process, can express various colors and three-dimensional patterns, can maintain a metallic texture, and is resistant to external impact and has excellent reliability against salt water, etc., as the printing layer (43) is protected by a thin film (44).

[0094] However, the general metal card (40) according to the fourth example has a UV pattern layer (45) exposed to the outside, so it is not only susceptible to damage from external impact, but is also easily exposed to external contamination and vulnerable to surface scratches.

[0095]

[0096] FIG. 5 is a cross-sectional view showing a typical metal card according to the fifth example.

[0097] As illustrated in FIG. 5, a general metal card (50) according to the fifth example exhibits a thermal transfer method in which a bonding member (52), a printing layer (53), a deposition layer (54), a UV printing layer (55), and a hard coating layer (56) are arranged in sequence on the upper surface of a metal sheet (51). At this time, the general metal card (50) according to the fifth example can be manufactured by forming a hard coating layer (56), a UV printing layer (55), a deposition layer (54), and a printing layer (53) in sequence on a thermal transfer thin film release film (not shown), transferring them through the metal sheet (51) and the bonding member (52), and then removing the thermal transfer thin film release film.

[0098] Here, the metal sheet (51) can be formed from stainless steel or aluminum.

[0099] The printed layer (53) can be formed by printing decorative patterns, colors, characters, etc. with tint (translucent) or opaque ink.

[0100] The deposition layer (54) is formed by vacuum deposition to serve as a reflector for the pattern, and the deposition specifications, such as silver, color, or transparent, can be determined according to the required decoration (design) specifications.

[0101] The UV printing layer (55) is a layer that forms a three-dimensional pattern, and usually a UV three-dimensional pattern is formed using a UV pattern molding machine with a transparent UV paint and a pattern mold.

[0102] A hard coating layer (56) is formed for the purpose of preventing scratches on the surface, and the pencil hardness of the surface is at the 3H level.

[0103] However, the general metal card (50) according to the above-described fifth example has limited color expression, and there is a risk that the printed layer (53) may be easily damaged by external impact.

[0104] In addition, the general metal card (50) according to the above-described fifth example has the disadvantage of being vulnerable to reliability issues with salt water, etc., and having a high price due to low yield, as well as being vulnerable to surface scratches.

[0105]

[0106] FIG. 6 is a cross-sectional view showing a typical metal card according to the 6th example.

[0107] As illustrated in FIG. 6, a general metal card (60) according to the 6th example shows a metal deposition method in which a metal deposition layer (64) is formed on the upper surface of a metal sheet (62) and a CNC engraving pattern (66) is formed on the metal deposition layer (64).

[0108] Here, the metal sheet (62) can be formed from stainless steel or aluminum.

[0109] The metal deposition layer (64) can be formed by performing color vacuum deposition directly on the metal sheet (62) to express a color. The equipment and process for this metal deposition layer (64) are different from the E-beam deposition used to deposit on a general polymer film. That is, high pressure and temperature are required to maintain bonding strength with the metal in order to perform metal deposition on the upper surface of the metal sheet (62), and the colors that can be expressed are also limited.

[0110] A CNC engraving pattern (66) can be formed by CNC engraving characters or decorative designs. This CNC engraving pattern (66) is formed to bring out the metallic texture and gloss while allowing a three-dimensional tactile sensation when touched by hand.

[0111] The general metal card (60) according to the 6th example described above has the advantage of being simple to process and maintaining a metallic texture.

[0112] However, the general metal card (60) according to the 6th example can only express monotonous colors and colors, is expensive due to increased process costs for forming the metal deposition layer (64), and has the disadvantage of being susceptible to scratches and contamination.

[0113]

[0114] As mentioned above, conventional metal cards have difficulty expressing various decorative effects while maintaining the unique texture and luster of the metal material. Thus, although metal materials possess excellent rigidity and elasticity, preventing them from bending under external impact and allowing for long-term use, their surface decorative effects are easily damaged, and there are also consumers who do not prefer the cold feel of metal.

[0115]

[0116] In order to solve these problems, the present invention aims to fundamentally resolve issues such as difficulty in expressing decorative effects, cold touch, and damage to decoration while maximizing the advantages of metal cards.

[0117] To this end, a glass film tactile metal card having high hardness and high gloss characteristics according to an embodiment of the present invention is formed by laminating a glass film material layer onto a metal sheet and additionally printing a design pattern, characters, logo, etc. on the upper surface of the glass film material layer using transparent UV or translucent UV ink to form a UV printed layer.

[0118] As a result, the glass film tactile metal card having high hardness and high gloss characteristics according to the embodiment of the present invention can utilize the advantages of the metal material and the excellent surface hardness and elegant gloss of the glass film material, and can simultaneously express various colors and three-dimensional pattern effects.

[0119] This will be explained in more detail below with reference to the attached drawings.

[0120]

[0121] (1st embodiment)

[0122] FIG. 7 is a perspective view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a first embodiment of the present invention, and FIG. 8 is a cross-sectional view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a first embodiment of the present invention.

[0123] Referring to FIGS. 7 and 8, a glass film tactile metal card (100) having high hardness and high gloss characteristics according to the first embodiment of the present invention comprises a metal sheet (110), a printing layer (120), a bonding member (130), and a glass film material layer (140).

[0124]

[0125] The metal sheet (110) is a part that forms the framework of the glass film tactile metal card (100) and is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, it is preferable that the metal sheet (110) be formed of stainless steel or aluminum. The thickness of the metal sheet (110) is determined according to the structure of the layer formed on the metal sheet (110) or the decorative effect, and it is preferable that it have a thickness of 0.2 to 0.6 mm.

[0126]

[0127] A printed layer (120) is formed on a metal sheet (110). At this time, the printed layer (120) may be formed by directly printing a decorative pattern, color, text, etc., on the upper surface of the metal sheet (110) using tint (translucent) or opaque ink. The printing method of the printed layer (120) mainly uses a digital printing method, but depending on the decorative specifications, various printing methods such as offset printing, silk screen printing, and pad printing may also be used.

[0128]

[0129] The bonding member (130) is positioned between the printing layer (120) and the glass film material layer (140) and serves to bond the glass film material layer (140) to the metal sheet (110) on which the printing layer (120) is formed.

[0130] These bonding members (130) are used to maintain adhesion between layers when laminating a metal material, such as a metal sheet (110), and a glass film material layer (140). To this end, the bonding members (130) may include one or more selected from thermosetting adhesives and photocurable adhesives.

[0131] In this way, the bonding member (130) laminates the metal sheet (110) on which the printed layer (120) is formed and the glass film material layer (140) using a thermosetting adhesive or a photocuring adhesive (UV-curing adhesive) and applying a constant amount of heat or light and pressure. At this time, when laminating the glass film material layer (140) and the metal sheet (110), it is more preferable to use a UV-curing adhesive because the glass film material layer (140) is transparent.

[0132]

[0133] A glass film material layer (140) is disposed on a printed layer (120) via a bonding member (130). This glass film material layer (140) includes one or more selected from a high-hardness resin reinforced film, a high-hardness hard coating film, Ultra Thin Glass (UTG), Clear Polyimide Film (CPI) film, and tempered glass. Among these, it is more preferable to use a high-hardness resin reinforced film as the glass film material layer (140).

[0134] For high-hardness resin-reinforced films, the product name E-Glass, commercialized by Esol Chemical Co., Ltd., or the product name Shill Plus, commercialized by Nippon Steel & Chemical, may be used. E-Glass or Shill Plus are high-hardness films with a surface hardness of 6H to 9H or higher, and possess high hardness and high gloss at a level that allows them to be used as substitutes for tempered glass.

[0135] High-hardness hard-coated films refer to thin films such as PET (polyethylene terephthalate), PI (polyimide), PC (polycarbonate), and PVC (Polyvinyl Chloride) that have a high-hardness hard coating, and usually have a surface hardness of 4H to 9H.

[0136] UTG (Ultra Thin Glass) is a thin film glass with a thickness of 100㎛ or less, used as a material for foldable phone displays, and is a material with a surface hardness of 9H or higher.

[0137] Tempered glass is a material primarily used in mobile phones, and after processing, it undergoes a strengthening process to achieve high hardness and elasticity of 9H or higher.

[0138] It is preferable to use a glass film material layer (140) having a surface hardness of 6H to 9H or higher, and it is more preferable to use one having a surface hardness of 6H to 9H.

[0139] It is preferable to use a glass film material layer (140) having a thickness of 75 to 200 μm, and more preferable to use one having a thickness of 100 to 150 μm. If the thickness of the glass film material layer (140) is less than 75 μm, it may be difficult to ensure durability. Conversely, if the thickness of the glass film material layer (140) exceeds 200 μm, it is not desirable because it increases the overall thickness of the glass film tactile metal card (100), resulting in a condition that runs counter to the trend of making it thin and light.

[0140]

[0141] In addition, the glass film tactile metal card (100) having high hardness and high gloss characteristics according to the first embodiment of the present invention may further include an IC chip (150).

[0142] An IC chip (150) is placed on a glass film material layer (140) and can be inserted into an IC insertion hole that penetrates a portion of a metal sheet (110). This IC chip (150) is coupled to one edge of the glass film material layer (140) and serves to store and recognize card user information.

[0143]

[0144] Hereinafter, a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to the first embodiment of the present invention will be described.

[0145] FIGS. 9 to 11 are process schematic diagrams illustrating a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to a first embodiment of the present invention.

[0146] As shown in FIG. 9, a printing layer (120) is printed on the upper surface of a metal sheet (110) in a direct printing manner to manufacture a direct printing method decoration metal sheet (125).

[0147] Here, the metal sheet (110) is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, the metal sheet (110) is preferably formed of stainless steel or aluminum. The thickness of the metal sheet (110) is determined according to the structure of the layer formed on the metal sheet (110) or the decorative effect, and it is preferable to have a thickness of 0.2 to 0.6 mm.

[0148] In addition, the printed layer (120) can be formed by directly printing a decorative pattern, color, text, etc., on the upper surface of the metal sheet (110) using tint (translucent) or opaque ink. While digital printing is mainly used for the printing method of the printed layer (120), various printing methods such as offset printing, silk screen printing, and pad printing may be used depending on the decorative specifications.

[0149]

[0150] Next, as shown in FIG. 10, one or more selected from thermosetting adhesives and photocuring adhesives are applied to the surface of a decoration metal sheet (125) manufactured by direct printing, and a glass film material layer (140) is laminated, then placed together in a lamination jig and laminated under set conditions. Accordingly, a glass film decoration metal sheet (175 in FIG. 11) is completed, in which the decoration metal sheet (125) and the glass film material layer (140) are laminated onto the decoration metal sheet (125) via a bonding member (130).

[0151] Afterwards, an NFC antenna layer (160) and a back printing film (170) can be additionally laminated to the lower surface of the decoration metal sheet (125) through a first adhesive layer (132) and a second adhesive layer (134) as a separate additional process. At this time, each of the first and second adhesive layers (132, 134) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

[0152] Here, the NFC antenna layer (160) is formed to generate induced power and transmit a wireless signal when a metal card is brought close to a payment terminal. To this end, the NFC antenna layer (160) is formed of a metal material having a rectangular closed-loop shape and performs the role of an antenna to smoothly transmit a wireless signal to the payment terminal by generating an induced current when a metal card is brought close to the payment terminal.

[0153] The back printing film (170) is placed below the NFC antenna layer (160). This back printing film (170) is a film on which a magnetic bar, customer information, card information, card number, etc. are printed on a PVC film, and while digital printing is the basic method of printing, offset printing or silk screen printing may be used as needed.

[0154]

[0155] Next, as shown in FIG. 11, CNC machining is performed on a glass film decoration metal sheet (175) to form an IC insertion hole (H), and then an IC chip (150) is inserted into the IC insertion hole (H) to complete the final product, a glass film tactile metal card (100).

[0156] The IC chip (150) is bonded to one edge of the glass film material layer (140) and serves to store and recognize card user information.

[0157]

[0158] (2nd Example)

[0159] FIG. 12 is a perspective view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a second embodiment of the present invention, and FIG. 13 is a cross-sectional view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a second embodiment of the present invention.

[0160] Referring to FIG. 12 and FIG. 13, a glass film tactile metal card (200) having high hardness and high gloss characteristics according to a second embodiment of the present invention comprises a metal sheet (210), a printing layer (220), a bonding member (230), a glass film material layer (240), and a UV printing layer (250).

[0161]

[0162] The metal sheet (210) is a part that forms the framework of the glass film tactile metal card (200) and is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, it is preferable that the metal sheet (210) be formed of stainless steel or aluminum. The thickness of the metal sheet (210) is determined according to the structure of the layer formed on the metal sheet (210) or the decorative effect, and it is preferable that it have a thickness of 0.2 to 0.6 mm.

[0163]

[0164] A printed layer (220) is formed on a metal sheet (210). At this time, the printed layer (220) may be formed by directly printing a decorative pattern, color, text, etc., on the upper surface of the metal sheet (210) using tint (translucent) or opaque ink. The printing method of the printed layer (220) mainly uses a digital printing method, but various printing methods such as offset printing, silk screen printing, and pad printing may be used depending on the decorative specifications.

[0165]

[0166] The bonding member (230) is positioned between the printing layer (220) and the glass film material layer (240) and serves to bond the glass film material layer (240) to the metal sheet (210) on which the printing layer (220) is formed.

[0167] These bonding members (230) are used to maintain adhesion between layers when laminating a metal material, such as a metal sheet (210), and a glass film material layer (240). To this end, the bonding members (230) may include one or more selected from thermosetting adhesives and photocurable adhesives.

[0168] In this way, the bonding member (230) laminates the metal sheet (210) and the glass film material layer (240) on which the printed layer (220) is formed using a thermosetting adhesive or a photocuring adhesive (UV-curing adhesive) and a constant amount of heat or light and pressure. At this time, when laminating the glass film material layer (240) and the metal sheet (210), it is more preferable to use a UV-curing adhesive because the glass film material layer (240) is transparent.

[0169]

[0170] A glass film material layer (240) is disposed on a printed layer (220) via a bonding member (230). This glass film material layer (240) includes one or more selected from a high-hardness resin reinforced film, a high-hardness hard coating film, Ultra Thin Glass (UTG), Clear Polyimide Film (CPI) film, and tempered glass. Among these, it is more preferable to use a high-hardness resin reinforced film as the glass film material layer (240).

[0171] For high-hardness resin-reinforced films, the product name E-Glass, commercialized by Esol Chemical Co., Ltd., or the product name Shill Plus, commercialized by Nippon Steel & Chemical, may be used. E-Glass or Shill Plus are high-hardness films with a surface hardness of 6H to 9H or higher, and possess high hardness and high gloss at a level that allows them to be used as substitutes for tempered glass.

[0172] High-hardness hard-coated films refer to thin films such as PET (polyethylene terephthalate), PI (polyimide), PC (polycarbonate), and PVC (Polyvinyl Chloride) that have a high-hardness hard coating, and usually have a surface hardness of 4H to 9H.

[0173] UTG (Ultra Thin Glass) is a thin film glass with a thickness of 100㎛ or less, used as a material for foldable phone displays, and is a material with a surface hardness of 9H or higher.

[0174] Tempered glass is a material primarily used in mobile phones, and after processing, it undergoes a strengthening process to achieve high hardness and elasticity of 9H or higher.

[0175] It is preferable to use a glass film material layer (240) having a surface hardness of 6H to 9H or higher, and it is more preferable to use one having a surface hardness of 6H to 9H.

[0176] It is preferable to use a glass film material layer (240) having a thickness of 75 to 200 μm, and more preferable to use one having a thickness of 100 to 150 μm. If the thickness of the glass film material layer (240) is less than 75 μm, it may be difficult to ensure durability. Conversely, if the thickness of the glass film material layer (240) exceeds 200 μm, it is not desirable because it increases the overall thickness of the glass film tactile metal card (200), resulting in a condition that runs counter to the trend of making it thin and light.

[0177]

[0178] A UV printing layer (250) is formed on a glass film material layer (240). This UV printing layer (250) is a layer that forms a three-dimensional pattern and is formed by printing design patterns, characters, logos, etc. using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV printing layer (250) forms a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable that the UV printing layer (250) be formed with a thickness of 10 μm or less, more preferably a thickness of 1 to 10 μm.

[0179] In this way, the second embodiment of the present invention can be utilized in various types of metal cards, and a UV printing layer (250) having a UV three-dimensional pattern such as transparent, translucent, or opaque can be selectively applied on a glass film material layer (240), which is a high-hardness glass film layer, according to the customer's requirements.

[0180] Accordingly, the glass film tactile metal card (200) having high hardness and high gloss characteristics according to the second embodiment of the present invention can utilize the advantages of the metal material and the excellent surface hardness and elegant gloss of the glass film material by laminating a glass film material layer (240) to a metal sheet (210) and forming a UV printing layer (250) by additionally printing a design pattern, text, logo, etc. using transparent UV or translucent UV ink on the upper surface of the glass film material layer (240), thereby enabling the simultaneous expression of various colors and three-dimensional pattern effects.

[0181]

[0182] Additionally, the glass film tactile metal card (200) having high hardness and high gloss characteristics according to the second embodiment of the present invention may further include at least one of a CNC engraving pattern (260) and an IC chip (270).

[0183] A CNC engraving pattern (260) can be formed on a UV printing layer (250).

[0184] These CNC engraving patterns (260) can be formed by CNC engraving characters or decorative designs. The CNC engraving patterns (260) are formed to bring out the metallic texture and gloss while allowing a three-dimensional tactile sensation when touched by hand.

[0185] Additionally, the CNC engraving pattern (260) also serves the purpose of recognizing the type of card when a visually impaired person uses a glass film tactile metal card (200). At this time, it is preferable to form the CNC engraving pattern (260) by engraving it to a depth where a part of the metal sheet (210) is exposed, so that the gloss and texture of the metal material are revealed and can be touched.

[0186] An IC chip (270) is placed on a UV printing layer (250) and can be inserted into an IC insertion hole that penetrates a portion of a metal sheet (210). This IC chip (270) is bonded to one edge of the glass film material layer (240) and the UV printing layer (250) and serves to store and recognize card user information.

[0187]

[0188] Hereinafter, a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to a second embodiment of the present invention will be described.

[0189] FIGS. 14 to 18 are process schematic diagrams illustrating a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to a second embodiment of the present invention.

[0190] As shown in FIG. 14, a printing layer (220) is printed on the upper surface of a metal sheet (210) in a direct printing manner to manufacture a direct printing method decoration metal sheet (225).

[0191] Here, the metal sheet (210) is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, the metal sheet (210) is preferably formed of stainless steel or aluminum. The thickness of the metal sheet (210) is determined according to the structure of the layer formed on the metal sheet (210) or the decorative effect, and it is preferable to have a thickness of 0.2 to 0.6 mm.

[0192] Additionally, the printed layer (220) can be formed by directly printing a decorative pattern, color, text, etc., on the upper surface of the metal sheet (210) using tint (translucent) or opaque ink. While digital printing is mainly used for the printing method of the printed layer (220), various printing methods such as offset printing, silk screen printing, and pad printing may be used depending on the decorative specifications.

[0193]

[0194] Next, as illustrated in FIG. 15, one or more selected from a thermosetting adhesive and a photocurable adhesive are applied to the surface of a decoration metal sheet (225) manufactured by a direct printing method, and a glass film material layer (240) is laminated, then placed together in a lamination jig and laminated under set conditions. Accordingly, a glass film material layer (240) is laminated onto the decoration metal sheet (225) via a bonding member (230).

[0195] Afterward, an NFC antenna layer (280) and a back printing film (290) can be additionally laminated to the lower surface of the decoration metal sheet (225) through a first adhesive layer (232) and a second adhesive layer (234) as a separate additional process. At this time, each of the first and second adhesive layers (232, 234) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

[0196] Here, the NFC antenna layer (280) is formed to generate induced power and transmit a wireless signal when a metal card is brought close to a payment terminal. To this end, the NFC antenna layer (280) is formed of a metal material having a rectangular closed-loop shape and performs the role of an antenna to smoothly transmit a wireless signal to the payment terminal by generating an induced current when a metal card is brought close to the payment terminal.

[0197] The back printing film (290) is placed below the NFC antenna layer (280). This back printing film (290) is a film on which a magnetic bar, customer information, card information, card number, etc. are printed on a PVC film, and while digital printing is the basic method of printing, offset printing or silk screen printing may be used as needed.

[0198] Here, a glass film decoration metal sheet (295) is formed by including a decoration metal sheet (225), a bonding member (230), and a glass film material layer (240). At this time, the glass film decoration metal sheet (295) may further include an NFC antenna layer (280), a back printing film (290), and first and second adhesive layers (232, 234).

[0199]

[0200] Next, as illustrated in FIG. 16, a UV printing layer (250) is formed by printing a design pattern, text, logo, etc., on a glass film decoration metal sheet (295) using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV printing layer (250) is formed by creating a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable to form the UV printing layer (250) with a thickness of 10 μm or less, more preferably with a thickness of 1 to 10 μm.

[0201] In this step, when forming a UV printing layer (250) by printing a design pattern, characters, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc., the characters between the printing layer (220) formed on the metal sheet (210) and the UV printing layer (250) must be aligned so that they match.

[0202] In this way, the second embodiment of the present invention can be utilized in various types of metal cards, and a UV printing layer (250) having a UV three-dimensional pattern such as transparent, translucent, or opaque can be selectively applied on a glass film material layer (240), which is a high-hardness glass film layer, according to the customer's requirements.

[0203]

[0204] Next, as shown in FIGS. 16 to 18, CNC machining is performed on a glass film decoration metal sheet (295) and a UV printing layer (250) to form a CNC engraving pattern (260) and an IC insertion hole (H), and then an IC chip (270) is inserted into the IC insertion hole (H) to complete the final product, a glass film tactile metal card (200).

[0205] In this stage, for mass production, it is preferable that the glass film decoration metal sheet (295) having a UV printing layer (250) formed thereon be fed into a multi-array structure in the form of a matrix such as 1 × 16, 1 × 18, 1 × 24 based on the metal card, and then CNC machining is performed to cut it into cells to produce the final product, the glass film tactile metal card (200).

[0206] Here, the CNC engraving pattern (260) can be formed by CNC engraving characters or decorative designs. The CNC engraving pattern (260) is formed to preserve the metallic texture and gloss while providing a three-dimensional tactile sensation when touched. At this time, it is desirable to engrave the CNC engraving pattern (260) to a depth where a part of the metal sheet (210) is exposed, so that the gloss and texture of the metal material are revealed and can be felt.

[0207] Only a portion of the metal sheet (210) must be precisely machined so that cracks or chipping do not occur in the glass film material layer (240) during such CNC carving or CNC shape cutting.

[0208] The IC chip (270) is bonded to one edge of the glass film material layer (240) and serves to store and recognize card user information.

[0209]

[0210] (3rd Example)

[0211] FIG. 19 is a perspective view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a third embodiment of the present invention, and FIG. 20 is a cross-sectional view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a third embodiment of the present invention.

[0213]

[0214] The metal sheet (310) is a part that forms the framework of the glass film tactile metal card (300) and is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, it is preferable that the metal sheet (310) be formed of stainless steel or aluminum. The thickness of the metal sheet (310) is determined according to the structure of the layer formed on the metal sheet (310) or the decorative effect, and it is preferable that it have a thickness of 0.2 to 0.6 mm.

[0215]

[0216] A thin film (330) is laminated onto a metal sheet (310). Depending on the requirements, a film of various materials may be used for this thin film (330). More specifically, the thin film (330) comprises one or more materials selected from PET (polyethylene terephthalate), PVC (polyvinyl chloride), PC (polycarbonate), TPU (thermoplastic polyurethane), PI (polyimide), Acryl, and PMMA (polymethyl methacrylate).

[0217] It is preferable that such thin film (330) has a thickness of 10 to 200 μm, and more preferable that it has a thickness of 25 to 188 μm. If the thickness of the thin film (330) is less than 10 μm, it is difficult to ensure durability, and there is a risk of bending deformation occurring during lamination. Conversely, if the thickness of the thin film (330) exceeds 200 μm, it increases the overall thickness of the metal card (300), which results in a condition that runs counter to the trend of making it thin and light, so it is not desirable.

[0218]

[0219] A color printing layer (320) is formed on the lower surface of a thin film (330). This color printing layer (320) is a layer for printing the color and pattern of decoration on the thin film (330), and can be formed by printing with tint (translucent) glossy ink, translucent ink, or matte ink to make the gloss and texture of the metal material visible after lamination. At this time, the printing method mainly uses a digital printing method, but various printing methods such as offset printing, silk screen printing, and pad printing may also be used depending on the decoration specifications.

[0220]

To this end, the first bonding member (312) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

[0223]

[0224] A UV pattern molding layer (340) is formed on the upper surface of a thin film (330). This UV pattern molding layer (340) is a layer that forms a three-dimensional pattern and is formed by printing a design pattern, text, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV pattern molding layer (340) forms a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable that the UV pattern molding layer (340) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0225]

[0226] A deposition layer (350) is formed on a UV pattern molding layer (340). This deposition layer (350) is a layer that is vacuum-deposited to serve as a reflector for the pattern, and the deposition specification is determined to be silver, color, transparent, etc., depending on the decorative specifications required. When a color printing layer (320) is formed, silver deposition or transparent deposition is used for the deposition layer (350), and when a color printing layer (320) is not formed, the deposition layer (350) implements the color through color deposition. Therefore, in the present invention, transparent deposition or silver deposition may be used for the deposition layer (350).

[0227]

[0228] The glass film material layer (360) is laminated onto the deposition layer (350) via the second bonding member (314).

[0229] For high-hardness resin-reinforced films, the product name E-Glass, commercialized by Esol Chemical Co., Ltd., or the product name Shill Plus, commercialized by Nippon Steel & Chemical, may be used. E-Glass or Shill Plus are high-hardness films with a surface hardness of 6H to 9H or higher, and possess high hardness and high gloss at a level that allows them to be used as substitutes for tempered glass.

[0230] High-hardness hard-coated films refer to thin films such as PET (polyethylene terephthalate), PI (polyimide), PC (polycarbonate), and PVC (Polyvinyl Chloride) that have a high-hardness hard coating, and usually have a surface hardness of 4H to 9H.

[0231] UTG (Ultra Thin Glass) is a thin film glass with a thickness of 100㎛ or less, used as a material for foldable phone displays, and is a material with a surface hardness of 9H or higher.

[0232] Tempered glass is a material primarily used in mobile phones, and after processing, it undergoes a strengthening process to achieve high hardness and elasticity of 9H or higher.

[0234] It is preferable to use a glass film material layer (360) having a thickness of 75 to 200 μm, and more preferable to use one having a thickness of 100 to 150 μm. If the thickness of the glass film material layer (360) is less than 75 μm, it may be difficult to ensure durability. Conversely, if the thickness of the glass film material layer (360) exceeds 200 μm, it is not desirable because it increases the overall thickness of the glass film tactile metal card (300), resulting in a condition that runs counter to the trend of making it thin and light.

[0235]

[0236] The second bonding member (314) is disposed between the deposition layer (350) and the glass film material layer (360) to bond the deposition layer (350) and the glass film material layer (360). This second bonding member (314) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

At this time, it is preferable that the UV printing layer (370) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0240] In this way, the third embodiment of the present invention can be utilized in various types of metal cards, and a UV printing layer (370) having a UV three-dimensional pattern such as transparent, translucent, or opaque can be selectively applied on a glass film material layer (360), which is a high-hardness glass film layer, according to the customer's requirements.

[0241] Accordingly, the glass film tactile metal card (300) having high hardness and high gloss characteristics according to the third embodiment of the present invention is formed by first laminating a thin film film (330) having a color printing layer (320) and a UV pattern molding layer (340) formed on a metal sheet (310) to form a film lamination type decoration metal sheet, and secondly laminating a glass film material layer (360) to the film lamination type decoration metal sheet to form a glass film decoration metal sheet.

[0242] Afterwards, by using transparent UV or translucent UV ink to additionally print design patterns, characters, logos, etc. on the upper surface of the glass film decoration metal sheet to form a UV printing layer (370), the advantages of the metal material and the excellent surface hardness and elegant gloss of the glass film material can be utilized, and various colors and three-dimensional pattern effects can be expressed simultaneously.

[0243] Accordingly, the glass film tactile metal card (300) having high hardness and high gloss characteristics according to the third embodiment of the present invention can simultaneously express UV pattern effects, the unique texture of a glossy metal sheet, the gloss of glass, and decorative printing pattern effects.

[0244] A CNC engraving pattern (380) can be formed on a UV printing layer (370). This CNC engraving pattern (380) can be formed by CNC engraving characters or decorative designs. The CNC engraving pattern (380) is formed to provide a metallic texture and gloss while allowing a three-dimensional tactile sensation when touched.

[0245] Additionally, the CNC engraving pattern (380) also serves the purpose of recognizing the type of card when a visually impaired person uses a glass film tactile metal card (300). At this time, it is desirable that the CNC engraving pattern (380) be engraved to a depth where a part of the metal sheet (310) is exposed so that the gloss and texture of the metal material are revealed and can be touched.

[0246] An IC chip (390) is placed on a UV printing layer (370) and can be inserted into an IC insertion hole that penetrates a portion of a metal sheet (310).

At this time, it is preferable that the UV pattern molding layer (340) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0253] The color printing layer (320) is a layer for printing the color and pattern of decoration on a thin film (330), and can be formed by printing with tint (translucent) glossy ink, translucent ink, or matte ink to make the gloss and texture of the metal material visible after lamination. At this time, the printing method mainly uses digital printing, but depending on the decoration specifications, various printing methods such as offset printing, silk screen printing, and pad printing may also be used.

[0254] Additionally, the metal sheet (310) is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, the metal sheet (310) is preferably formed from stainless steel or aluminum. The thickness of the metal sheet (310) is determined according to the structure of the layer formed on the metal sheet (310) or the decorative effect, and it is preferable to have a thickness of 0.2 to 0.6 mm.

[0255]

[0256] Next, as shown in FIG. 22, a deposition layer (250) is formed on a film-laminated type decoration metal sheet (345), then one or more selected from a thermosetting adhesive and a photocurable adhesive are applied, and a glass film material layer (360) is laminated, then placed together in a lamination jig and laminated under set conditions.

[0257] Afterward, as a separate additional process, an NFC antenna layer (392) and a back-side printing film (394) can be additionally laminated to the lower surface of a film-laminated type decoration metal sheet (345) through a first adhesive layer (316) and a second adhesive layer (318). At this time, each of the first and second adhesive layers (316, 318) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

[0258] Here, the NFC antenna layer (392) is formed to generate induced power and transmit a wireless signal when a metal card is brought close to the payment terminal. To this end, the NFC antenna layer (392) is formed of a metal material having a rectangular closed-loop shape and performs the role of an antenna to smoothly transmit a wireless signal to the payment terminal by generating an induced current when the metal card is brought close to the payment terminal.

[0259] The back printing film (394) is placed below the NFC antenna layer (392). This back printing film (394) is a film on which a magnetic bar, customer information, card information, card number, etc. are printed on a PVC film, and while digital printing is the basic method, offset printing or silk screen printing may be used as needed.

[0260] Here, a film laminated type glass film decoration metal sheet (395) is formed by including a film laminated type decoration metal sheet (345), first and second bonding members (312, 314), and a glass film material layer (360). At this time, the film laminated type glass film decoration metal sheet (395) may further include an NFC antenna layer (392), a back printing film (394), and first and second adhesive layers (316, 318).

[0261]

[0262] Next, as illustrated in FIG. 23, a UV printing layer (370) is formed by printing a design pattern, text, logo, etc., on a film-laminated type glass film decoration metal sheet (395) using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV printing layer (370) is formed by creating a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable to form the UV printing layer (370) with a thickness of 10 μm or less, more preferably with a thickness of 1 to 10 μm.

[0263] In this step, when forming a UV printing layer (370) by printing a design pattern, characters, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc., the characters between the color printing layer (320) formed on the metal sheet (310) and the UV printing layer (370) must be aligned so that they match.

[0264] Next, CNC machining is performed to form a CNC engraving pattern (380) and an IC insertion hole (H), and then an IC chip (390) is inserted into the IC insertion hole (H) to complete the final product, a glass film tactile metal card (300).

[0265] Here, the CNC engraving pattern (380) can be formed by CNC engraving characters or decorative designs. The CNC engraving pattern (380) is formed to preserve the metallic texture and gloss while allowing a three-dimensional tactile sensation to be felt when touched. At this time, it is preferable to form the CNC engraving pattern (380) by engraving to a depth where a part of the metal sheet (310) is exposed, so that the gloss and texture of the metal material are revealed and can be felt.

[0266] When such CNC carving or CNC shape cutting, only a portion of the metal sheet (310) must be precisely machined so that cracks or chipping do not occur in the glass film material layer (360).

[0267] The IC chip (390) is bonded to one edge of the glass film material layer (360) and serves to store and recognize card user information.

[0268]

[0269] (Fourth Example)

[0270] FIG. 24 is a perspective view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a fourth embodiment of the present invention, and FIG. 25 is a cross-sectional view showing a glass film tactile metal card having high hardness and high gloss characteristics according to a fourth embodiment of the present invention.

[0271] Referring to FIGS. 24 and 25, a glass film tactile metal card (400) having high hardness and high gloss characteristics according to the fourth embodiment of the present invention comprises a metal sheet (410), a glass film material layer (450), a color printing layer (440), a UV pattern molding layer (430), a deposition layer (420), and a bonding member (412).

[0272]

[0273] The metal sheet (410) is a part that forms the framework of the glass film tactile metal card (400) and is made of a metal material to maintain excellent rigidity and elasticity, as well as a unique gloss and texture. For this purpose, it is preferable that the metal sheet (410) be formed of stainless steel or aluminum. The thickness of the metal sheet (410) is determined according to the structure of the layer formed on the metal sheet (410) or the decorative effect, and it is preferable that it have a thickness of 0.2 to 0.6 mm.

[0274]

[0275] A glass film material layer (450) is laminated onto a metal sheet (410) via a bonding member (412). This glass film material layer (450) includes one or more selected from a high-hardness resin reinforced film, a high-hardness hard coating film, Ultra Thin Glass (UTG), Clear Polyimide Film (CPI) film, and tempered glass. Among these, it is more preferable to use a high-hardness resin reinforced film as the glass film material layer (450).

[0276] For high-hardness resin-reinforced films, the product name E-Glass, commercialized by Esol Chemical Co., Ltd., or the product name Shill Plus, commercialized by Nippon Steel & Chemical, may be used. E-Glass or Shill Plus are high-hardness films with a surface hardness of 6H to 9H or higher, and possess high hardness and high gloss at a level that allows them to be used as substitutes for tempered glass.

[0277] High-hardness hard-coated films refer to thin films such as PET (polyethylene terephthalate), PI (polyimide), PC (polycarbonate), and PVC (Polyvinyl Chloride) that have a high-hardness hard coating, and usually have a surface hardness of 4H to 9H.

[0278] UTG (Ultra Thin Glass) is a thin film glass with a thickness of 100㎛ or less, used as a material for foldable phone displays, and is a material with a surface hardness of 9H or higher.

[0279] Tempered glass is a material primarily used in mobile phones, and after processing, it undergoes a strengthening process to achieve high hardness and elasticity of 9H or higher.

[0280] It is preferable to use a glass film material layer (450) having a surface hardness of 6H to 9H or higher, and it is more preferable to use one having a surface hardness of 6H to 9H.

[0281] It is preferable to use a glass film material layer (450) having a thickness of 75 to 200 μm, and more preferable to use one having a thickness of 100 to 150 μm. If the thickness of the glass film material layer (450) is less than 75 μm, it may be difficult to ensure durability. Conversely, if the thickness of the glass film material layer (450) exceeds 200 μm, it is not desirable because it increases the overall thickness of the glass film tactile metal card (400), resulting in a condition that runs counter to the trend of making it thin and light.

[0282]

[0283] A color printing layer (440) is formed on the lower surface of a glass film material layer (450). This color printing layer (440) is a layer for printing the color and pattern of decoration on the glass film material layer (450), and can be formed by printing with tint (translucent) glossy ink, translucent ink, or matte ink to make the gloss and texture of the metal material visible after lamination. At this time, a digital printing method is mainly used, but various printing methods such as offset printing, silk screen printing, and pad printing may also be used depending on the decoration specifications.

[0284]

[0285] A UV pattern molding layer (430) is formed on the lower surface of a color printing layer (440). This UV pattern molding layer (430) is a layer that forms a three-dimensional pattern and is formed by printing a design pattern, text, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV pattern molding layer (430) forms a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable that the UV pattern molding layer (430) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0286]

[0287] A deposition layer (420) is formed on the lower surface of a UV pattern molding layer (430). This deposition layer (420) is a layer that is vacuum-deposited to serve as a reflector for the pattern, and the deposition specification is determined to be silver, color, transparent, etc., depending on the decorative specifications required. When a color printing layer (440) is formed, silver deposition or transparent deposition is used for the deposition layer (420), and when a color printing layer (440) is not formed, the deposition layer (420) implements the color through color deposition. Therefore, in the present invention, transparent deposition or silver deposition may be used for the deposition layer (420).

[0288]

[0289] A bonding member (412) is placed between a metal sheet (410) and a deposition layer (420) to bond the metal sheet (410) and a glass film material layer (450).

[0290] These bonding members (412) are used to maintain adhesion between layers when laminating a metal material, such as a metal sheet (410), and a glass film material layer (450). To this end, the bonding members (412) may include one or more selected from thermosetting adhesives and photocurable adhesives.

[0291]

[0292] In addition, the glass film tactile metal card (400) having high hardness and high gloss characteristics according to the fourth embodiment of the present invention may further include at least one of a UV printing layer (460), a CNC engraving pattern (470), and an IC chip (480).

[0293] A UV printing layer (460) is formed on a glass film material layer (450). This UV printing layer (460) is a layer that forms a three-dimensional pattern and is formed by printing design patterns, characters, logos, etc. using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV printing layer (460) forms a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable that the UV printing layer (460) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0294] In this way, the fourth embodiment of the present invention can be utilized in various types of metal cards, and a UV printing layer (460) having a UV three-dimensional pattern such as transparent, translucent, or opaque can be selectively applied on a glass film material layer (450), which is a high-hardness glass film layer, according to customer requirements.

[0295] Accordingly, the glass film tactile metal card (400) having high hardness and high gloss characteristics according to the fourth embodiment of the present invention can utilize the advantages of the metal material and the excellent surface hardness and elegant gloss of the glass film material, and can simultaneously express various colors and three-dimensional pattern effects. This is achieved by laminating a glass film material layer (450), in which a color printing layer (440), a UV pattern molding layer (430), and a deposition layer (420) are formed on a metal sheet (410) using a bonding member (412), and then forming a UV printing layer (460) by additionally printing a design pattern, text, logo, etc., on the upper surface of the glass film material layer (450) using transparent UV or translucent UV ink.

[0296] Accordingly, the glass film tactile metal card (400) having high hardness and high gloss characteristics according to the fourth embodiment of the present invention can simultaneously express the UV pattern effect, the unique texture of the glossy metal sheet (410), the gloss of the glass, and the decorative printing pattern effect.

[0297] A CNC engraving pattern (470) can be formed on a UV printing layer (460). This CNC engraving pattern (470) can be formed by CNC engraving characters or decorative designs. The CNC engraving pattern (470) is formed to provide a metallic texture and gloss while allowing a three-dimensional tactile sensation when touched.

[0298] Additionally, the CNC engraving pattern (470) also serves the purpose of recognizing the type of card when a visually impaired person uses a glass film tactile metal card (400). At this time, it is desirable that the CNC engraving pattern (470) be engraved to a depth where a part of the metal sheet (410) is exposed so that the gloss and texture of the metal material are revealed and can be touched.

[0299] An IC chip (480) is placed on a UV printing layer (460) and can be inserted into an IC insertion hole that penetrates a portion of a metal sheet (410). This IC chip (480) is bonded to one edge of the glass film material layer (450) and the UV printing layer (460) and serves to store and recognize card user information.

[0300]

[0301] Hereinafter, a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to the fourth embodiment of the present invention will be described.

[0302] FIGS. 26 to 28 are process schematic diagrams illustrating a method for manufacturing a glass film tactile metal card having high hardness and high gloss characteristics according to a fourth embodiment of the present invention.

[0303] As shown in FIG. 26, a glass film decoration sheet (455) is manufactured by sequentially laminating a color printing layer (440), a UV pattern molding layer (430), and a deposition layer (420) on the lower surface of a glass film material layer (450).

[0304] Here, the glass film material layer (450) includes one or more selected from high-hardness resin reinforced film, high-hardness hard coating film, UTG (Ultra Thin Glass), CPI (Clear Polyimide Film) film, and tempered glass. Among these, it is more preferable to use a high-hardness resin reinforced film as the glass film material layer (450).

[0305] In addition, the color printing layer (440) is a layer for printing the color and pattern of decoration on the glass film material layer (450), and can be formed by printing with tint (translucent) glossy ink, translucent ink, or matte ink to make the gloss and texture of the metal material visible after lamination. At this time, the printing method mainly uses digital printing, but various printing methods such as offset printing, silk screen printing, and pad printing may also be used depending on the decoration specifications.

[0306] Additionally, the UV pattern molding layer (430) is a layer that forms a three-dimensional pattern and is formed by printing a design pattern, text, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV pattern molding layer (430) forms a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable that the UV pattern molding layer (430) be formed with a thickness of 10㎛ or less, more preferably 1 to 10㎛.

[0307] Additionally, the deposition layer (420) is a layer that is vacuum-deposited to serve as a reflector for the pattern, and the deposition specification is determined to be silver, color, transparent, etc., depending on the decorative specifications required. When a color printing layer (440) is formed, the deposition layer (420) is silver deposition or transparent deposition, and when a color printing layer (440) is not formed, the deposition layer (420) is color deposition to realize the color. Therefore, in the present invention, the deposition layer (420) may be transparent deposition or silver deposition.

[0308]

[0309] Next, as shown in FIG. 27, one or more selected from thermosetting adhesive and photocurable adhesive are applied to the lower surface of the glass film decoration sheet (455) and laminated with the metal sheet (410) to manufacture a glass film decoration metal sheet (495).

[0310] Afterwards, in a separate additional process, an NFC antenna layer (492) and a back printing film (494) can be additionally laminated to the lower surface of the glass film decoration metal sheet (495) through a first adhesive layer (not shown) and a second adhesive layer (414). At this time, each of the first and second adhesive layers (414) may include one or more selected from a thermosetting adhesive and a photocurable adhesive.

[0311] Here, the NFC antenna layer (492) is formed to generate induced power and transmit a wireless signal when a metal card is brought close to the payment terminal. To this end, the NFC antenna layer (492) is formed of a metal material having a rectangular closed-loop shape and performs the role of an antenna to smoothly transmit a wireless signal to the payment terminal by generating an induced current when the metal card is brought close to the payment terminal.

[0312] The back printing film (494) is placed below the NFC antenna layer (492). This back printing film (494) is a film on which a magnetic bar, customer information, card information, card number, etc. are printed on a PVC film, and while digital printing is the basic method of printing, offset printing or silk screen printing may be used as needed.

[0313]

[0314] Next, as illustrated in FIG. 28, a UV printing layer (460) is formed by printing a design pattern, text, logo, etc., on a glass film decoration metal sheet (495) using transparent or translucent UV color ink, opaque UV ink, etc. To this end, the UV printing layer (460) is formed by creating a UV three-dimensional pattern such as transparent, translucent, or opaque using a UV pattern molding machine that utilizes a pattern mold. At this time, it is preferable to form the UV printing layer (460) with a thickness of 10 μm or less, more preferably with a thickness of 1 to 10 μm.

[0315] In this step, when forming a UV printing layer (460) by printing a design pattern, characters, logo, etc. using transparent or translucent UV color ink, opaque UV ink, etc., the characters between the color printing layer (440) and the UV printing layer (460) must be aligned so that they match.

[0316] Next, CNC machining is performed to form a CNC engraving pattern (470) and an IC insertion hole (H), and then an IC chip (480) is inserted into the IC insertion hole (H) to complete the final product, a glass film tactile metal card (400).

[0317] Here, the CNC engraving pattern (470) can be formed by CNC engraving characters or decorative designs. The CNC engraving pattern (470) is formed to preserve the metallic texture and gloss while providing a three-dimensional tactile sensation when touched. At this time, it is desirable to engrave the CNC engraving pattern (470) to a depth where a part of the metal sheet (410) is exposed, so that the gloss and texture of the metal material are revealed and can be felt.

[0318] When such CNC carving or CNC shape cutting, only a portion of the metal sheet (410) must be precisely machined so that cracks or chipping do not occur in the glass film material layer (450).

[0319] The IC chip (480) is bonded to one edge of the glass film material layer (450) and serves to store and recognize card user information.

[0320]

[0321] As seen above, according to the embodiments of the present invention, by laminating a glass film layer onto a metal sheet, the cold feel of the metal material can be improved, and the problem of various decorative effects on the surface of the metal sheet being easily damaged can be fundamentally resolved.

[0322] In addition, according to the embodiments of the present invention, it is possible to differentiate the design by simultaneously experiencing a beautiful gloss similar to tempered glass while maintaining the inherent luster of the metal material.

[0323] In addition, according to the embodiments of the present invention, the glass film layer on the surface of the glass film material layer does not get scratched or contaminated even after long-term use, thereby increasing the reliability of the product.

[0324] In addition, according to embodiments of the present invention, contamination caused by fine grooves on the surface of the metal sheet is prevented, so that it can always be maintained like a new product even after long-term use, and by introducing a UV printing layer in addition to the gloss of the surface, a tactile sensation can also be felt, making it easier for visually impaired people to distinguish cards when using them.

[0325] In addition, according to embodiments of the present invention, the limitations of metal cards in terms of decorative effect can be overcome to produce colorful, colorful, and three-dimensional decorative effects through various color expressions, three-dimensional patterns, and tactile decorative printing.

[0326] In addition, according to embodiments of the present invention, a printing pattern, characters, logo, etc. are additionally printed on the glass film layer of the glass film material layer to maximize the three-dimensional pattern effect and allow for a tactile sensation, and also provide an anti-slip effect when gripping.

[0327] In addition, according to embodiments of the present invention, when CNC engraving is performed in conjunction with UV printing on the glass film layer of the glass film material layer, a more three-dimensional and differentiated decorative effect and tactile effect can be obtained simultaneously.

[0328]

[0329] Although the present invention has been described above with reference to embodiments, various changes and modifications can be made by those skilled in the art to which the present invention pertains. Such changes and modifications are considered to be within the scope of the present invention as long as they do not depart from the technical concept provided by the present invention.
