Description

Decorative card having a double three-dimensional pattern and method of manufacturing the same

[0001] The present invention relates to a decorative card having a double three-dimensional pattern and a method for manufacturing the same, and more specifically, to a decorative card having a double three-dimensional pattern capable of simultaneously expressing a beautiful gloss and various holographic effects on the surface of the decorative card and a method for manufacturing the same.

[0002]

[0003] Cards currently in circulation are manufactured using various materials and designs, such as PVC, metal, and ceramic. Types of cards may include credit cards, bank cards, transportation cards, debit cards, local currency cards, membership cards, prepaid cards, smart card keys for cars, premium business cards, keyrings, and more.

[0004] Card issuers are competing by combining unique designs and functions, and design differentiation is becoming increasingly important in situations where card capabilities are similar. Therefore, attractive designs that catch the consumer's eye are required.

[0005] Current card designs are limited to flat, print-oriented forms. Accordingly, efforts are underway to develop decorative cards featuring dual three-dimensional patterns to differentiate their design.

[0006]

[0007] Hereinafter, a conventional decorative card will be described with reference to the attached drawings.

[0008] FIG. 1 is an exploded perspective view showing a decorative card with a multilayer structure according to the prior art, and FIG. 2 is a combined cross-sectional view showing a decorative card with a multilayer structure according to the prior art.

[0009] As illustrated in FIGS. 1 and 2, a conventional multilayer decorative card (100) includes a front decorative member layer (110), a support layer (120), an NFC antenna layer (130), a rear decorative layer (140), and a magnetic bar layer (150).

[0010] The front decorative layer (110) can be formed by printing color ink, black ink, etc., on a polymer film to decorate designs such as pictures and characters. Here, an IC chip (160) for storing and recognizing card user information may be attached to one edge of the front decorative layer (110).

[0011] A support layer (120) is placed on the lower surface of the front decorative member layer (110). A PVC film or a PET film may be used for this support layer (120).

[0012] An NFC antenna layer (130) is disposed on the lower surface of the support layer (120). This NFC antenna layer (130) is formed to generate inductive power and transmit a wireless signal when a decorative card (100) is brought close to a payment terminal.

[0013] The rear decorative layer (140) is placed on the lower surface of the NFC antenna layer (130). This rear decorative layer (140) can be formed by printing color ink, black ink, etc., or by displaying a design such as a picture or text through laser engraving.

[0014] The magnetic bar layer (150) is placed on the lower surface of the rear decorative layer (140). This magnetic bar layer (150) protects the rear decorative layer (140), and a magnetic bar is attached to the back surface, which stores user information of the decorative card (100), etc.

[0015]

[0016] The aforementioned conventional multi-layered decorative card (100) is completed by preparing multiple layers of materials to provide design and function, applying heat and pressure, and laminating them using a bonding material (170) placed between each layer.

[0017] That is, a multi-layered decorative card (100) according to the prior art is completed by applying a bonding agent (170) to each layer of the front decorative layer (110), support layer (120), NFC antenna layer (130), rear decorative layer (140), and magnetic bar layer (150), and then laminating them by applying a certain amount of heat and pressure using a heat press.

[0018] Conventional multilayer decorative cards (100) are mostly multilayer PVC cards, and designs are expressed on the surface through various printing methods.

[0019] Recently, attempts have been made to differentiate designs by imprinting three-dimensional patterns on decorative cards, but this also fails to simultaneously express a beautiful gloss and various holographic effects.

[0020]

[0021] Meanwhile, FIG. 3 is a perspective view showing a single-layer type metal card according to the prior art.

[0022] As illustrated in FIG. 3, a conventional single-layer type metal card (200) includes a metal layer (210) and an IC chip (230). In this case, it is preferable to use aluminum (Al) or stainless steel (SUS) material for the metal layer (210) to compensate for the poor durability of plastic and to highlight a high-end image.

[0023] A front decorative pattern (220) with a design implemented by printing or grazing may be formed on the front surface of the metal layer (210), and a rear decorative pattern (not shown) with a design implemented by printing or grazing may be formed on the rear surface of the metal plate (210).

[0024] The IC chip (230) is coupled to one edge of the metal layer (210) and serves to store and recognize card user information.

[0025]

[0026] FIG. 4 is an exploded perspective view showing a conventional laminated type metal card, and FIG. 5 is a combined cross-sectional view showing a conventional laminated type metal card.

[0027] As shown in FIGS. 4 and 5, a conventional laminated metal card (300) includes a front decorative layer (310), a metal layer (320), and a rear decorative layer (330).

[0028] The front decorative layer (310) can be formed by printing color ink, black ink, etc., on a polymer film to decorate a design such as a picture or text.

[0029] A metal layer (320) is placed on the underside of the front decorative member layer (310). It is preferable to use aluminum (Al) or stainless steel (SUS) material for this metal layer (320) to compensate for the poor durability of the plastic and to highlight a high-end image.

[0030] The rear decorative layer (330) is placed on the lower surface of the metal layer (320). This rear decorative layer (330) can be formed by printing color ink, black ink, etc., or by implementing a design such as a picture or text through laser engraving.

[0031] Here, the front decorative layer (310) and the metal layer (320) may be joined by a bonding member (350) located between them. A hot melt adhesive may be used as the bonding member (350), but is not limited thereto.

[0032]

[0033] As mentioned above, conventional metal cards are generally classified into two types: single-layer type and laminated type.

[0034] Among these, the single-layer type metal card is decorated with front and back decorative patterns by direct printing or laser engraving.

[0035] In addition, for laminated metal cards, a film-type front decorative layer is separately produced on the front and laminated using a heat curing method, and the back decorative layer is completed by direct printing or laser engraving (Graving).

[0036] As such, conventional metal cards implement designs by directly printing on the surface of the metal layer or through graving.

[0037] In addition, recently, patterns are applied directly onto the metal layer using a UV molding method, or a method of separately producing and laminating a decorative film is also used.

[0038] However, conventional metal cards are also unable to simultaneously express a beautiful gloss and various holographic effects.

[0039] A relevant prior art document is Korean Registered Patent Publication No. 10-1490396 (published on February 5, 2015), which describes a double-layered holographic patch and a method for manufacturing the same.

[0040]

[0041] The objective of the present invention is to provide a decorative card having a double three-dimensional pattern capable of simultaneously expressing a beautiful gloss and various holographic effects on the surface of the decorative card, and a method for manufacturing the same.

[0042]

[0044] In step (a) above, the primary decorative member comprises a substrate layer, a color ink layer, a first imprinting pattern layer, a reflective layer, and a black ink layer stacked sequentially from the top.

[0045] In step (c) above, the laminate is heat-pressed at 150 to 250°C under a pressure of 30 to 60 bar.

[0046] In step (d) above, the surface-reinforced surface is formed by increasing the surface density and surface roughness of the upper surface of the substrate layer through heat-press lamination using the metal plate.

[0047] After step (e) above, (f) a step of cutting the multilayer film sheet layer on which the second imprinting pattern layer is formed, unit cell by cell; further comprises

[0048]

[0049] A decorative card having a double three-dimensional pattern according to a first embodiment of the present invention for achieving the above objective comprises: a primary decorative member; a support layer disposed on the lower surface of the primary decorative member; an NFC antenna layer disposed on the lower surface of the support layer; a rear decorative layer disposed on the lower surface of the NFC antenna layer; a magnetic bar layer disposed on the lower surface of the rear decorative layer; and a second imprinting pattern layer disposed on the upper surface of the substrate layer of the primary decorative member; wherein the substrate layer of the primary decorative member has a surface reinforcement surface formed on its upper surface.

[0050] The above primary decorative member includes a substrate layer, a color ink layer, a first imprinting pattern layer, a reflective layer, and a black ink layer stacked sequentially from the top.

[0051]

[0052] A method for manufacturing a decorative card having a double three-dimensional pattern according to a second embodiment of the present invention for achieving the above objective comprises: (a) a step of loading a metal sheet layer, wherein a primary decorative member, a bonding member, and a metal layer are arranged sequentially from top to bottom on a dedicated tray; (b) a step of positioning the dedicated tray loaded with the metal sheet layer on a heat press plate, and then aligning a metal plate on the primary decorative member of the metal sheet layer; (c) a step of positioning a heat press device above the metal plate, spaced apart from the metal plate, and then applying heat and pressure to the metal sheet layer using the heat press device to laminate; (d) a step of separating the metal plate from the laminated metal sheet layer and aligning the metal sheet layer having a surface reinforcement surface on a UV molding plate; and (e) a step of applying UV paint on the metal sheet layer having a surface reinforcement surface to form a UV paint layer, and then imprinting the UV paint layer with a pattern mold to form a second imprinting pattern layer.

[0053] In step (d) above, the surface-reinforced surface is formed by increasing the surface density and surface roughness of the upper surface of the substrate layer through heat-press lamination using the metal plate.

[0054] After step (e) above, (f) a step of cutting the metal sheet layer on which the second imprinting pattern layer is formed into unit cells; further comprises

[0055]

[0056] A decorative card having a double three-dimensional pattern according to a second embodiment of the present invention for achieving the above objective comprises: a primary decorative member; a metal layer disposed on the lower surface of the primary decorative member; and a second imprinting pattern layer disposed on the upper surface of the substrate layer of the primary decorative member; wherein the substrate layer of the primary decorative member has a surface reinforcement surface formed on its upper surface.

[0057] The above primary decorative member includes a substrate layer, a translucent color ink layer, a first imprinting pattern layer, a reflective layer, and a black ink layer stacked sequentially from the top.

[0058]

[0059] The decorative card having a double three-dimensional pattern according to the present invention and the method for manufacturing the same utilize a lamination process using a metal plate and a heat press device to increase the surface density of the base layer of the primary decorative member and increase the surface roughness, thereby completing a hard surface reinforced surface.

[0060] As a result, the decorative card having a double three-dimensional pattern according to the present invention and the method for manufacturing the same provide first and second imprinting pattern layers on the inside and outside of a primary decorative member, and since the second imprinting pattern layer is formed by an imprinting process on a substrate layer having a surface reinforcement surface, it becomes possible to realize a double three-dimensional pattern that can simultaneously express a beautiful gloss and various holographic effects on the surface of the decorative card.

[0061] Accordingly, the decorative card having a double three-dimensional pattern and the method for manufacturing the same according to the present invention can express a three-dimensional design through the 3D three-dimensional pattern, and can achieve more colorful and three-dimensional color expression through matching with various prints and colors.

[0062] In addition, the decorative card having a double three-dimensional pattern according to the present invention and the method for manufacturing the same provide a beautiful gloss on the surface of the decorative card and can simultaneously express various holographic effects, thereby providing high satisfaction to customers and consumers with a design differentiated from existing cards, and consumers can choose a unique and differentiated design.

[0063] In addition, the decorative card having a double three-dimensional pattern according to the present invention and the method of manufacturing the same can give a strong impression to others by highlighting individuality with personal patterns and colors when used as a business card, and can give a luxurious feeling with three-dimensionality and color when used as a smart card key for automobiles.

[0064] In addition, the decorative card having a double three-dimensional pattern according to the present invention and the method of manufacturing the same can preserve the elegant feel of metal even when using plastic material, thereby enabling the realization of a high-end plastic card.

[0065] Accordingly, the decorative card having a double three-dimensional pattern according to the present invention and the method for manufacturing the same are suitable for use in bank cards including credit cards, debit cards, and prepaid cards, local currency, transportation cards, membership cards, automobile smart card keys, RF ID key rings, employee cards and visitor passes, high-end personal business cards, promotional business cards, and various other card-shaped promotional materials and card-type goods.

[0079] 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.

[0080] A decorative card having a double three-dimensional pattern and a method for manufacturing the same according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0081]

[0082] (1st embodiment)

[0083] FIG. 6 is an exploded perspective view showing a decorative card having a double three-dimensional pattern according to a first embodiment of the present invention, and FIG. 7 is a combined cross-sectional view showing a decorative card having a double three-dimensional pattern according to a first embodiment of the present invention.

[0084] Referring to FIGS. 6 and 7, a decorative card (400) having a double three-dimensional pattern according to the first embodiment of the present invention includes a primary decorative member (410), a support layer (420), an NFC antenna layer (430), a rear decorative layer (440), a magnetic bar layer (450), and a second imprinting pattern layer (470).

[0085]

[0086] The first decorative member (410) may include a substrate layer (411), a color ink layer (412), a first imprinting pattern layer (413), a reflective layer (414), and a black ink layer (415) stacked sequentially from the top.

[0087] The substrate layer (411) is a part that forms the framework of the primary decorative member (410), and a PVC film or a PET film may be used.

[0088] The color ink layer (412) is placed on the lower surface of the substrate layer (411) and is formed to be transparent or translucent. This color ink layer (412) can be formed by printing using a high-resolution digital printer with ink specifically designed for digital printers to express the design and color of the decorative card (400).

[0089] The first imprinting pattern layer (413) is placed on the lower surface of the color ink layer (412). This first imprinting pattern layer (413) is formed by molding various patterns using a UV-curing transparent paint and a pattern mold to create a three-dimensional effect on the primary decorative member (410), and this process is called imprinting.

[0090] A reflective layer (414) is placed on the lower surface of the first imprinting pattern layer (413). This reflective layer (414) is formed to enhance the pattern effect of the first imprinting pattern layer (413) and can be formed by depositing silver (Ag).

[0091] A black ink layer (415) is placed on the lower surface of the reflective layer (414). This black ink layer (415) can be formed by performing shielding printing using shielding black ink to protect the reflective layer (414) and then curing it.

[0092]

[0093] A support layer (420) is placed on the lower surface of the primary decorative member (410). This support layer (420) may be made of a PVC film or a PET film, just like the base layer (411) of the primary decorative member (410).

[0094]

[0095] An NFC antenna layer (430) is disposed on the lower surface of the support layer (420). This NFC antenna layer (430) is formed to generate induced power and transmit a wireless signal when a decorative card (400) is brought close to a payment terminal. To this end, the NFC antenna layer (430) 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 decorative card (400) is brought close to the payment terminal.

[0096]

[0097] The rear decorative layer (440) is placed on the lower surface of the NFC antenna layer (430). This rear decorative layer (440) can be formed by printing color ink, black ink, etc., or by displaying pictures, characters, etc. through laser engraving.

[0098]

[0099] The magnetic bar layer (450) is placed on the lower surface of the rear decorative layer (440). This magnetic bar layer (450) protects the rear decorative layer (440), and a magnetic bar is attached to the back surface, which stores user information of the decorative card (400), etc.

[0100]

[0101] The decorative card (400) having a double three-dimensional pattern according to the first embodiment of the present invention described above may have a primary decorative member (410), a support layer (420), an NFC antenna layer (430), a rear decorative layer (440), and a magnetic bar layer (450) arranged in order from the top, and may be bonded by a bonding member (480) arranged between each layer.

[0102] Here, a multilayer sheet layer (460) is formed by including a primary decorative member (410), a support layer (420), an NFC antenna layer (430), a rear decorative layer (440), a magnetic bar layer (450), and a bonding member (480).

[0103] A bonding member (480) may be formed between the primary decorative member (410) and the support layer (420), between the support layer (420) and the NFC antenna layer (430), between the NFC antenna layer (430) and the rear decorative layer (440), and between the rear decorative layer (440) and the magnetic bar layer (450), respectively. A hot melt adhesive may be used as the bonding member (480), but is not limited thereto.

[0104]

[0105] The second imprinting pattern layer (470) is placed on the upper surface of the substrate layer (411) of the primary decorative member (410).

[0106] This second imprinting pattern layer (470) is formed by an imprinting method using a pattern mold and a UV-curing transparent paint to create a double three-dimensional effect on the primary decorative member (410) together with the first imprinting pattern layer (413).

[0107] In particular, the substrate layer (411) of the primary decorative member (410) of the present invention has a surface reinforcement surface formed on its upper surface. This surface reinforcement surface is formed by increasing the surface density and surface roughness of the upper surface of the substrate layer (411) of the primary decorative member (410) through heat press lamination using a metal plate.

[0108] To this end, in the present invention, a metal plate is positioned and aligned on the primary decorative member (410) of the multilayer film sheet layer (460), and then heat and pressure are applied to the multilayer film sheet layer (460) using a heat press device to laminate them.

[0109] It is preferable to laminate the metal plate in a state where it is positioned to come into contact with the upper surface of the base layer (411) of the primary decorative member (410) in order to make the surface of the base layer (411) of the primary decorative member (410) a hard surface.

[0110] The reason for using such a metal plate is that during the lamination process, high heat and pressure are applied to the substrate layer (411) of the primary decorative member (410), and thus the surface density and surface roughness of the substrate layer (411) of the primary decorative member (410) are increased by the high heat and pressure to form a hard surface reinforced surface on the upper surface of the substrate layer (411) of the primary decorative member (410). Therefore, if a metal plate with a rough surface is used, the surface shape of the metal plate is transferred as is to the substrate layer (411) of the primary decorative member (410), and even if a three-dimensional pattern is imprinted, there is a problem in that the pattern effect and the three-dimensional effect do not appear clearly.

[0111] Therefore, it is preferable to use a metal plate with a smooth surface, and it is even more preferable to use a metal plate that has undergone a polishing process.

[0112] In this way, in the present invention, instead of forming a second imprinting pattern layer (470) directly on a first decorative member (410), a metal plate is placed on a multilayer film sheet layer (460) comprising a first decorative member (410), a support layer (420), an NFC antenna layer (430), a rear decorative layer (440), a magnetic bar layer (450), and a bonding member (480), and heat and pressure are applied using a heat press device to laminate them.

[0113] By using a lamination process using a metal plate and a heat press device, the surface density of the base layer (411) of the primary decorative member (410) is increased and the surface roughness is increased, thereby making it possible to complete a hard surface-reinforced surface. Accordingly, when a second imprinting pattern layer (470) is formed on the base layer (411) having a surface-reinforced surface by an imprinting process, it becomes possible to realize a double three-dimensional pattern that can simultaneously express a beautiful gloss and various holographic effects.

[0114] Thus, the reason for proceeding with the second imprinting process after lamination is that if the second imprinting coating layer (470) is formed first on the substrate layer (411) of the first decorative member (410) and then lamination is performed, the shape of the second imprinting coating layer (470) is deformed due to high heat and pressure, and the effects such as brightness and texture of the second imprinting pattern layer (470) are significantly reduced.

[0115] Therefore, in order to make the base layer (411) of the first decorative member (410) into a hard surface, an imprinting process to form the second imprinting coating layer (470) must be performed after laminating using a metal plate, so that the brightness and texture of the second imprinting pattern layer (470) can be well preserved without deformation of the shape of the second imprinting coating layer (470).

[0116]

[0117] This will be explained in more detail below through the method for manufacturing a decorative card having a double three-dimensional pattern according to the first embodiment of the present invention attached.

[0118] FIGS. 8 to 12 are process cross-sectional views illustrating a method for manufacturing a decorative card having a double three-dimensional pattern according to a first embodiment of the present invention.

[0119] As shown in FIG. 8, a multilayer sheet layer (460) is loaded on a dedicated tray (610) in which a primary decorative member (410), a support layer (420), an NFC antenna layer (430), a rear decorative layer (440), and a magnetic bar layer (450) are arranged in order from top to bottom, with bonding members (480) arranged between each layer.

[0120] Here, the primary decorative member (410) may include a substrate layer, a color ink layer, a first imprinting pattern layer, a reflective layer, and a black ink layer stacked sequentially from the top.

[0121] A bonding member (480) may be formed between the primary decorative member (410) and the support layer (420), between the support layer (420) and the NFC antenna layer (430), between the NFC antenna layer (430) and the rear decorative layer (440), and between the rear decorative layer (440) and the magnetic bar layer (450), respectively. A hot melt adhesive may be used as the bonding member (480), but is not limited thereto.

[0122]

[0123] As shown in FIG. 9, a dedicated tray (610) loaded with a multilayer film sheet layer (460) is placed on a heat press plate (630), and then a metal plate (620) is positioned and aligned on the primary decorative member (410) of the multilayer film sheet layer (460).

[0124] In this step, it is preferable to position the metal plate (620) so as to be in contact with the upper surface of the base layer to make the surface of the base layer of the primary decorative member (410) a hard surface.

[0125] The reason for using such a metal plate (620) is that, during the lamination process, high heat and pressure are applied to the substrate layer of the primary decorative member (410), and thus the surface density and surface roughness of the substrate layer of the primary decorative member (410) are increased by the high heat and pressure to form a hard surface reinforced surface on the upper surface of the substrate layer of the primary decorative member (410). Therefore, if a metal plate with a rough surface is used, the surface shape of the metal plate is transferred as is to the substrate layer of the primary decorative member (410), and even if a three-dimensional pattern is imprinted, there is a problem in that the pattern effect and the three-dimensional effect do not appear clearly.

[0126] Therefore, it is preferable to use a metal plate (620) with a smooth surface, and it is more preferable to use a metal plate that has been polished.

[0127]

[0128] As shown in FIG. 10, a heat press device (640) is positioned above the metal plate (620) and then heat and pressure are applied to the multilayer film sheet layer (460) using the heat press device (640) to laminate them.

[0129] In this step, it is preferable to heat press the laminate at 150 to 250°C under a pressure of 30 to 60 bar, and more preferable to heat press it at 180 to 220°C under a pressure of 40 to 50 bar.

[0130] In the lamination stage, if the heat press compression temperature is less than 150°C or the heat press compression pressure is less than 30 bar, the surface density and surface roughness of the base layer of the primary decorative member (410) may not be sufficiently increased, and thus a hard surface reinforcement surface may not be formed on the upper surface of the base layer of the primary decorative member (410). Conversely, if the heat press compression temperature exceeds 250°C or the heat press compression pressure exceeds 60 bar, excessive heat and pressure may be applied, which may cause deformation of the shape of the primary decorative member (410), and thus is undesirable.

[0131]

[0132] As shown in FIG. 11, a metal plate (620 in FIG. 10) is removed from the laminated multilayer film sheet layer (460), and the multilayer film sheet layer (460) with a surface reinforcement surface formed is positioned and aligned on a UV molding plate (630).

[0133] By applying heat and pressure to the multilayer film sheet layer (460) using the aforementioned heat press device and laminating them, a hard surface reinforced surface is formed on the upper surface of the substrate layer of the primary decorative member (410).

[0134] This surface reinforcement surface is formed by increasing the surface density and surface roughness of the upper surface of the base layer of the primary decorative member (410) by heat press lamination using a metal plate.

[0135] Next, a UV paint is applied to a multilayer film sheet layer (460) on which a surface reinforcement surface is formed to form a UV paint layer (475), and then the UV paint layer (475) is imprinted with a pattern mold (650) to form a second imprinting pattern layer (470 in FIG. 12).

[0136] At this time, a compression roller (660) is positioned on the pattern mold (650). This compression roller (660) moves in a scanning manner and presses the pattern mold (650) on which a fine pattern or a holographic pattern is imprinted, thereby enhancing the depth and three-dimensionality of the second imprinting pattern layer formed on the substrate layer of the primary decorative member (410).

[0137] Accordingly, in the present invention, a first imprinting pattern layer is formed inside the first decorative member (410), and a second imprinting pattern layer is formed outside the first decorative member (410).

[0138] As a result, the present invention makes it possible to realize a dual three-dimensional pattern capable of simultaneously expressing a beautiful gloss and various holographic effects on the surface of a decorative card through the first and second imprinting pattern layers.

[0139] Thus, the reason for proceeding with the second imprinting process after lamination is that if the second imprinting coating layer (470) is formed first on the substrate layer (411) of the first decorative member (410) and then lamination is performed, the shape of the second imprinting coating layer (470) is deformed due to high heat and pressure, and the effects such as brightness and texture of the second imprinting pattern layer (470) are significantly reduced.

[0140] Therefore, in order to make the base layer (411) of the first decorative member (410) into a hard surface, an imprinting process to form the second imprinting coating layer (470) must be performed after laminating using a metal plate, so that the brightness and texture of the second imprinting pattern layer (470) can be well preserved without deformation of the shape of the second imprinting coating layer (470).

[0141]

[0142] As shown in FIG. 12, a multilayer sheet layer (460) having a second imprinting pattern layer (470) formed thereon is cut into unit cells to form a decorative card (400).

[0143] Such cutting may be performed by stamping with a press to match the drawing specifications required by the customer or by cutting the outer shape using a CNC engraving machine, but is not limited to these methods.

[0144] With this, the method for manufacturing a decorative card having a double three-dimensional pattern according to the first embodiment of the present invention may be terminated.

[0145]

[0146] (2nd Example)

[0147] FIG. 13 is an exploded perspective view showing a decorative card having a double three-dimensional pattern according to a second embodiment of the present invention, and FIG. 14 is a combined cross-sectional view showing a decorative card having a double three-dimensional pattern according to a second embodiment of the present invention.

[0148] Referring to FIGS. 13 and 14, a decorative card (500) having a double three-dimensional pattern according to a second embodiment of the present invention includes a primary decorative member (510), a metal layer (520), and a second imprinting pattern layer (540).

[0149]

[0150] The first decorative member (510) includes a substrate layer (510), a color ink layer (512), a first imprinting pattern layer (513), a reflective layer (514), and a black ink layer (515) stacked in order from top to bottom.

[0151] The substrate layer (511) is a part that forms the framework of the primary decorative member (510), and a PVC film or a PET film may be used.

[0152] The color ink layer (512) is placed on the lower surface of the substrate layer (511) and is formed to be transparent or translucent. This color ink layer (512) can be formed by printing using a high-resolution digital printer with ink specially made for digital printers to express the design and color of the decorative card (500).

[0153] The first imprinting pattern layer (513) is placed on the lower surface of the color ink layer (512). This first imprinting pattern layer (513) is formed by molding various patterns using a UV-curing transparent paint and a pattern mold to create a three-dimensional effect on the primary decorative member (510), and this process is called imprinting.

[0154] A reflective layer (514) is placed on the lower surface of the first imprinting pattern layer (513). This reflective layer (514) is formed to enhance the pattern effect of the first imprinting pattern layer (513) and can be formed by depositing silver (Ag).

[0155] A black ink layer (515) is placed on the lower surface of the reflective layer (514). This black ink layer (515) can be formed by performing shielding printing using shielding black ink to protect the reflective layer (514) and then curing it.

[0156]

[0157] A metal layer (520) is placed on the lower surface of the primary decorative member (510). It is preferable to use aluminum (AL) or stainless steel (SUS) material for this metal layer (520) to compensate for the poor durability of plastic and to highlight a high-end image. Among these, it is more preferable to use stainless steel material for the metal layer (520) because it is more resistant to moisture and sweat, which can increase convenience of use.

[0158] Here, a bonding member (550) may be formed between the primary decorative member (510) and the metal layer (520). A hot melt adhesive may be used as the bonding member (550), but is not limited thereto.

[0159] In the first embodiment of the present invention, a metal sheet layer (430) is formed by including a primary decorative member (510), a metal layer (520), and a bonding member (550).

[0160]

[0161] The second imprinting pattern layer (540) is placed on the upper surface of the substrate layer (511) of the primary decorative member (510).

[0162] This second imprinting pattern layer (540) is formed by an imprinting method in which various patterns, such as fine patterns and holographic patterns, are formed using a UV-curing transparent paint and a pattern mold to create a double three-dimensional effect on the primary decorative member (510) together with the first imprinting pattern layer (513).

[0163] In particular, the substrate layer (511) of the first decorative member (510) of the present invention has a surface reinforcement surface formed on its upper surface. This surface reinforcement surface is formed by increasing the surface density and surface roughness of the upper surface of the substrate layer (511) of the first decorative member (510) through heat press lamination using a metal plate.

[0164]

[0165] To this end, in the present invention, a metal plate is positioned and aligned on the primary decorative member (510) of the metal sheet layer (530), and then heat and pressure are applied to the metal sheet layer (510) using a heat press device to laminate them.

[0166] It is preferable to laminate the metal plate in a state where it is positioned to come into contact with the upper surface of the base layer (511) of the primary decorative member (510) in order to make the surface of the base layer (511) of the primary decorative member (510) a hard surface.

[0167] The reason for using such a metal plate is that during the lamination process, high heat and pressure are applied to the substrate layer (511) of the primary decorative member (510), and thus the surface density and surface roughness of the substrate layer (511) of the primary decorative member (510) are increased by the high heat and pressure to form a hard surface reinforced surface on the upper surface of the substrate layer (511) of the primary decorative member (510). Therefore, if a metal plate with a rough surface is used, the surface shape of the metal plate is transferred as is to the substrate layer (511) of the primary decorative member (510), and even if a three-dimensional pattern is imprinted, there is a problem in that the pattern effect and the three-dimensional effect do not appear clearly.

[0168] Therefore, it is preferable to use a metal plate with a smooth surface, and it is even more preferable to use a metal plate that has undergone a polishing process.

[0169] In this way, in the present invention, the second imprinting pattern layer (540) is not formed directly on the first decorative member (510), but rather a metal plate is placed on a metal sheet layer (530) including the first decorative member (510), a metal layer (520), and a bonding member (550), and heat and pressure are applied using a heat press device to laminate them.

[0170] By using a lamination process using a metal plate and a heat press device, the surface density of the base layer (511) of the primary decorative member (510) is increased and the surface roughness is increased, thereby making it possible to complete a hard surface-reinforced surface. Accordingly, when a second imprinting pattern layer (540) is formed on the base layer (511) having a surface-reinforced surface by an imprinting process, it becomes possible to realize a double three-dimensional pattern that can simultaneously express a beautiful gloss and various holographic effects.

[0171] Thus, the reason for proceeding with the second imprinting process after lamination is that if the second imprinting coating layer (540) is formed first on the substrate layer (511) of the first decorative member (510) and then lamination is performed, the shape of the second imprinting coating layer (540) is deformed due to high heat and pressure, and the effects such as brightness and texture of the second imprinting pattern layer (540) are significantly reduced.

[0172] Therefore, in order to make the base layer (511) of the first decorative member (510) into a hard surface, an imprinting process must be performed to form the second imprinting coating layer (540) after laminating it using a metal plate, so that the brightness and texture of the second imprinting pattern layer (540) can be well preserved without deformation of the shape of the second imprinting coating layer (540).

[0173]

[0174] This will be explained in more detail below through the method for manufacturing a decorative card having a double three-dimensional pattern according to the second embodiment of the present invention attached.

[0175] FIGS. 15 to 19 are process cross-sectional views illustrating a method for manufacturing a decorative card having a double three-dimensional pattern according to a second embodiment of the present invention.

[0176] As shown in FIG. 15, a metal sheet layer (530) is loaded on a dedicated tray (710) in which a primary decorative member (510), a bonding member (550), and a metal layer (520) are arranged in order from top to bottom.

[0177] Here, the primary decorative member (510) may include a substrate layer, a color ink layer, a first imprinting pattern layer, a reflective layer, and a black ink layer stacked sequentially from the top.

[0178] A metal layer (520) is placed on the lower surface of the primary decorative member (510). It is preferable to use aluminum (AL) or stainless steel (SUS) material for this metal layer (520) to compensate for the poor durability of plastic and to highlight a high-end image. Among these, it is more preferable to use stainless steel material for the metal layer (520) because it is more resistant to moisture and sweat, which can increase convenience of use.

[0179] A bonding member (550) is formed between the primary decorative member (510) and the metal layer (520) to bond the primary decorative member (510) and the metal layer (520). A hot melt adhesive may be used as the bonding member (550), but is not limited thereto.

[0180]

[0181] As shown in FIG. 16, a dedicated tray (710) loaded with a metal sheet layer (530) is placed on a heat press plate (730), and then a metal plate (720) is positioned and aligned on the primary decorative member (510) of the metal sheet layer (530).

[0182] In this step, it is preferable to position the metal plate (720) so as to be in contact with the upper surface of the base layer of the primary decorative member (510) in order to make the surface of the base layer of the primary decorative member (510) a hard surface.

[0183] The reason for using such a metal plate (720) is that, during the lamination process, high heat and pressure are applied to the substrate layer of the primary decorative member (510), and thus the surface density and surface roughness of the substrate layer of the primary decorative member (510) are increased by the high heat and pressure to form a hard surface reinforced surface on the upper surface of the substrate layer of the primary decorative member (510). Therefore, if a metal plate with a rough surface is used, the surface shape of the metal plate is transferred as is to the substrate layer of the primary decorative member (510), and even if a three-dimensional pattern is imprinted, there is a problem in that the pattern effect and the three-dimensional effect do not appear clearly.

[0184] Therefore, it is preferable to use a metal plate (720) with a smooth surface, and it is more preferable to use a metal plate that has been polished.

[0185]

[0186] As shown in FIG. 17, a heat press device (740) is positioned above the metal plate (720) and then heat and pressure are applied to the metal sheet layer (530) using the heat press device (740) to laminate them.

[0187] In this step, it is preferable to heat press the laminate at 150 to 250°C under a pressure of 30 to 60 bar, and more preferable to heat press it at 180 to 220°C under a pressure of 40 to 50 bar.

[0188] In the lamination stage, if the heat press compression temperature is less than 150°C or the heat press compression pressure is less than 30 bar, there is a risk that the surface density and surface roughness of the base layer of the primary decorative member (510) will not increase sufficiently, and thus a surface reinforcement surface may not be formed on the upper surface of the base layer of the primary decorative member (510). Conversely, if the heat press compression temperature exceeds 250°C or the heat press compression pressure exceeds 60 bar, there is a risk that the shape of the primary decorative member (510) may be deformed due to the application of excessive heat and pressure, so this is undesirable.

[0189]

[0190] As shown in FIG. 18, the metal plate (720 in FIG. 17) is detached from the laminated metal sheet layer (530), and the metal sheet layer (530) with the metal glossy surface formed is positioned and aligned on the UV molding plate (750).

[0191] By applying heat and pressure to the metal sheet layer (530) using the aforementioned heat press device and laminating them, a hard surface reinforced surface is formed on the upper surface of the base layer of the primary decorative member (510).

[0192] This surface reinforcement surface is formed by increasing the surface density and surface roughness of the upper surface of the base layer of the primary decorative member (510) by heat press lamination using a metal plate.

[0193] Next, a UV paint is applied to a metal sheet layer (530) on which a surface reinforcement layer is formed to form a UV paint layer (545), and then the UV paint layer (545) is imprinted with a pattern mold (760) to form a second imprinted pattern layer (540 of FIG. 19).

[0194] At this time, a compression roller (770) is positioned on the pattern mold (760). This compression roller (770) moves in a scanning manner and presses the pattern mold (760) on which a fine pattern or holographic pattern is imprinted, thereby enhancing the depth and three-dimensionality of the second imprinting pattern layer formed on the substrate layer of the primary decorative member (510).

[0195] Accordingly, in the present invention, a first imprinting pattern layer is formed inside the first decorative member (510), and a second imprinting pattern layer is formed outside the first decorative member (510).

[0196] As a result, the present invention makes it possible to realize a dual three-dimensional pattern capable of simultaneously expressing a beautiful gloss and various holographic effects on the surface of a decorative card through the first and second imprinting pattern layers.

[0197] In this way, the reason for proceeding with the second imprinting process after lamination is that if the second imprinting coating layer (540) is formed first on the substrate layer of the first decorative member (510) and then lamination is performed, the shape of the second imprinting coating layer (540) is deformed due to high heat and pressure, and the effects such as brightness and texture of the second imprinting pattern layer (540) are significantly reduced.

[0198] Therefore, in order to make the base layer of the first decorative member (510) into a hard surface, an imprinting process must be performed to form the second imprinting coating layer (540) after laminating using a metal plate, so that the brightness and texture of the second imprinting pattern layer (540) can be well preserved without deformation of the shape of the second imprinting coating layer (540).

[0199]

[0200] As shown in FIG. 19, a metal sheet layer (530) having a second imprinting pattern layer (540) formed thereon is cut into unit cells to form a decorative sheet (500).

[0201] Such cutting may be performed by stamping with a press to match the drawing specifications required by the customer or by cutting the outer shape using a CNC engraving machine, but is not limited to these methods.

[0202] With this, the method for manufacturing a decorative card having a double three-dimensional pattern according to the second embodiment of the present invention may be concluded.

[0203]

[0204] As seen so far, the decorative card having a double three-dimensional pattern and the method for manufacturing the same according to the embodiments of the present invention do not form a second imprinting pattern layer directly on a primary decorative member, but rather place a metal plate on a multilayer film sheet layer or a metal sheet layer including a primary decorative member, a support layer, an NFC antenna layer, a rear decorative layer, and a magnetic bar layer, and laminate them by applying heat and pressure with a heat press device.

[0205] As such, the decorative card having a double three-dimensional pattern and the method for manufacturing the same according to the embodiments of the present invention utilize a lamination process using a metal plate and a heat press device to increase the surface density of the base layer of the primary decorative member and increase the surface roughness, thereby completing a hard surface reinforced surface. The reason for forming such a surface reinforced surface is that a reflector must be present on the underside of the second imprinting pattern layer to realize the pattern effect of the second imprinting pattern layer. In the past, PVD or mirror silver ink was used, but the present invention is characterized by realizing the pattern effect of the second imprinting pattern layer by utilizing the surface reinforced surface as a reflector without using PVD or mirror silver ink.

[0206] Accordingly, the decorative card having a double three-dimensional pattern and the method for manufacturing the same according to the embodiments of the present invention have the advantage of simplifying the manufacturing process and securing cost competitiveness by reducing process costs, as they do not use deposition or mirror silver ink. In addition, while deposition or mirror silver ink is susceptible to humidity and can lead to reliability issues, the present method has the advantage of completely resolving such reliability problems.

[0207] As a result, the decorative card having a double three-dimensional pattern according to the embodiments of the present invention and the method for manufacturing the same provide first and second imprinting pattern layers on the inside and outside of a primary decorative member, and since the second imprinting pattern layer is formed by an imprinting process on a substrate layer having a surface reinforcement surface, it becomes possible to realize a double three-dimensional pattern that can simultaneously express a beautiful gloss and various holographic effects on the surface of the decorative card.

[0208] Accordingly, the decorative card having a double three-dimensional pattern and the method for manufacturing the same according to the embodiments of the present invention can express a three-dimensional design through the 3D three-dimensional pattern, and can achieve more colorful and three-dimensional color expression through matching with various prints and colors.

[0209] In addition, the decorative card having a double three-dimensional pattern according to the embodiments of the present invention and the method for manufacturing the same provide a beautiful gloss on the surface of the decorative card and can simultaneously express various holographic effects, thereby providing high satisfaction to customers and consumers with a design differentiated from existing cards, and consumers can choose a unique and differentiated design.

[0210] In addition, the decorative card having a double three-dimensional pattern according to the embodiments of the present invention and the method of manufacturing the same can give a strong impression to others by highlighting individuality with personal patterns and colors when used as a business card, and can give a luxurious feeling with three-dimensionality and color when used as a smart card key for automobiles.

[0211] In addition, the decorative card having a double three-dimensional pattern according to the embodiments of the present invention and the method of manufacturing the same can preserve the elegant feel of metal even when using plastic material, thereby realizing the premium quality of plastic cards.

[0212] Accordingly, the decorative card having a double three-dimensional pattern according to the embodiments of the present invention and the method for manufacturing the same are suitable for use in bank cards including credit cards, debit cards, and prepaid cards, local currency, transportation cards, membership cards, automobile smart card keys, RF ID key rings, employee cards and visitor passes, high-end personal business cards, promotional business cards, and various other card-shaped promotional materials and card-type goods.

[0213]

[0214] 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. Accordingly, the scope of rights of the present invention should be determined by the claims set forth below.
