Description

Technical Field

[0001] This invention relates to the fields of epoxy resin product manufacturing, DIY handicraft customization, surface decoration and bonding technology, and particularly to a water-resistant epoxy resin product and a method for manufacturing an epoxy resin product that is easy to pattern. Background Technology

[0002] There is a type of sticker on the market with a surface covered in epoxy resin. The epoxy resin is a transparent resin that cures into a transparent, glossy solid. This type of sticker is made by first printing a design on it, then dripping liquid epoxy resin onto the sticker. The liquid resin flows and covers the design. After a period of time, the epoxy resin sets into a layer, thus creating the epoxy resin sticker with the design and transparent solid resin.

[0003] Existing epoxy stickers are manufactured using industrial processes and cannot be made by consumers themselves. These stickers are made of film or paper. Manufacturers first print a design on the sticker. To allow the epoxy to flow on the sticker, a coating layer, such as an oil-based or silicone-based treatment agent, is then printed on the surface of the sticker after the design is printed. This allows the epoxy to flow and spread on the sticker surface. However, this coating layer, which promotes epoxy flow, results in weak adhesion of the epoxy to the sticker, making the epoxy layer easy to detach from the sticker. This limits its uses. Therefore, conventional epoxy stickers cannot come into contact with water and cannot be used on products that require washing; they are only suitable for items that will not come into contact with water, such as pencil cases and books.

[0004] In addition, the films or papers used in existing epoxy stickers can only be printed with patterns using printing machinery, and cannot be printed with home printers such as EPSON / HP / Canon, because there will be ink bleeding (ink spreading), making the pattern blurry. Therefore, the films or papers used in existing stickers can only be used in industrial processes and cannot be used by consumers. Consumers cannot make such epoxy products themselves.

[0005] Because the designs on existing epoxy stickers are printed using printing machinery, they are generic designs that lack uniqueness and variety, making them unattractive. These epoxy stickers are mass-produced by manufacturers, offering various styles and sizes for consumers to choose from. When sales are poor, this results in large inventories and stockpiled materials, wasting resources and manufacturing costs. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one object of the present invention is to provide a epoxy resin product that is washable and can be used on items that require washing; to overcome the lack of generic patterns in epoxy resin products, enabling the creation of various patterns; to allow consumers or businesses to DIY epoxy resin products with patterns; and to allow the epoxy resin product to be adhered to various items or the human body by adhesive or heat treatment.

[0007] Another object of the present invention is to provide an object with an epoxy resin pattern, wherein the aforementioned epoxy resin product is adhered to an object. The user can change the epoxy resin pattern on the object, or replace the object with an object having a different epoxy resin pattern.

[0008] Another object of the present invention is to provide a method for manufacturing epoxy resin products, which can easily produce epoxy resin products with patterns, and can produce epoxy resin products in small quantities and in a variety of ways.

[0009] To achieve the above objectives, the present invention provides, in a first aspect, a dispensing product comprising: The first adhesive layer is a hot melt adhesive layer; An ink bonding layer is disposed on the hot melt adhesive layer; A printing layer is formed by printing ink onto an ink bonding layer, and the printing layer has a pattern printed on it; A drop of adhesive, made of transparent resin, is applied to the printed layer and completely covers it.

[0010] According to a epoxy resin product of the present invention, the epoxy resin product can be heat-bonded onto an object by means of a molten adhesive layer. The epoxy resin layer is directly applied to the printed layer, and there is no coating or treatment agent between the epoxy resin layer and the printed layer, resulting in excellent adhesion. The epoxy resin layer will not detach or separate from the epoxy resin product; thus, the epoxy resin product is washable and dryable, and can be used on items that require washing, such as clothing and apparel.

[0011] To achieve the above objectives, the present invention provides a second aspect of an epoxy resin product comprising: The first adhesive layer is a self-adhesive layer; An intermediate layer is disposed on the self-adhesive layer; A bonding layer is formed by connecting the adhesive layer through the intermediate layer; A printing layer is formed by printing ink onto an ink bonding layer, and a pattern is printed on the printing layer; A drop of adhesive, made of transparent resin, is applied to the printed layer and completely covers it.

[0012] According to a dispensing product of the present invention, the dispensing product can adhere the self-adhesive layer to an object or human body. The self-adhesive layer is self-adhesive and its adhesive does not harden or completely lose its stickiness after application, allowing the dispensing product to be repeatedly applied. The dispensing layer is directly applied to the printed layer, with no coating or treatment agent between the dispensing layer and the printed layer, resulting in excellent adhesion. The dispensing layer will not detach or separate from the dispensing product; thus, the dispensing product is washable and tumble-dryable, and can be used on items that require washing, such as clothing and apparel.

[0013] Optionally, the epoxy layer is made of acrylic acid or a resin synthesized from acrylic acid and polyurethane, which is flexible and bendable; this allows the epoxy product to be adhered to flat or curved objects, as well as to objects or the human body, thereby enhancing the appearance of the object or the aesthetics of the human body.

[0014] Optionally, the epoxy resin product includes a base layer; the adhesive layer is disposed on the base layer and is separable from the base layer.

[0015] Optionally, the ink bonding layer is a polyurethane resin, an acrylic resin, or a resin synthesized from acrylic and polyurethane, which has good adhesion to the dropper layer and the adhesive layer.

[0016] Optionally, the ink bonding layer contains an ink fixative and / or a leveling agent. The ink fixative prevents the ink in the printing layer from spreading, ensuring that the pattern on the printing layer is clear and not blurry. The leveling agent promotes the fluidity and uniform diffusion of the liquid adhesive on the printing layer.

[0017] Optionally, at least one or more of silica, calcium carbonate, or titanium dioxide are added to the ink bonding layer. The ink bonding layer is opaque, for example, white or with added white powder, and the color of the object beneath the hot melt adhesive layer will not be visible in the epoxy resin product.

[0018] Optionally, when the adhesive layer is a hot melt adhesive, the epoxy resin product further includes: an opaque color-blocking layer disposed between the hot melt adhesive layer and the ink bonding layer, the color-blocking layer containing at least one or more of silicon dioxide, calcium carbonate, or titanium dioxide; the hot melt adhesive layer is a transparent hot melt adhesive layer. The color-blocking layer prevents the color of objects beneath the hot melt adhesive layer from being visible in the epoxy resin product.

[0019] Optionally, the intermediate layer is a thin film, such as a polyurethane, thermoplastic polyurethane, polyethylene terephthalate, or hot melt adhesive film, serving as a bonding medium between the adhesive layer and the ink bonding layer.

[0020] Furthermore, the intermediate layer is a polyethersulfone (PES) hot melt adhesive layer, and the self-adhesive layer is an acrylic resin self-adhesive layer, which becomes sticky when heated with the PES hot melt adhesive layer. Thus, the epoxy resin product can be cold-applied to an object or bonded to an object by hot pressing.

[0021] Optionally, the epoxy resin layer may contain at least one of glitter powder, phosphorescent powder, reflective powder, thermochromic powder, photochromic powder, or pearlescent powder, so that the epoxy resin product can emit phosphorescence, reflect light, change color with temperature or light intensity, or have colorful light.

[0022] Optionally, the epoxy resin layer contains a photocuring agent or a thermal catalyst, allowing the epoxy resin to be cured by ultraviolet (UV) or visible light, or by heat, within a short time.

[0023] To achieve the above objectives, a third aspect of the present invention provides a method for manufacturing a patterned epoxy resin product, comprising the following steps: 1. Prepare a printing material, which has at least an adhesive layer and an ink bonding layer, and print a patterned printing layer on the ink bonding layer of the printing material. 2. Cut the pattern of the printing layer on the printing material; 3. Remove the waste material other than the pattern from the printing material, and retain the pattern of the printed layer and the layer bonded to the pattern; 4. Apply adhesive to the printed layer to form an adhesive layer on the printed layer. The adhesive layer is a transparent resin. 5. Cure the epoxy resin layer to produce the epoxy resin product.

[0024] According to the present invention, a method for manufacturing patterned epoxy resin products allows users to create epoxy resin products DIY without the need for molds, thus satisfying DIY needs. The patterns and production quantities of the epoxy resin products are unlimited, allowing for small-batch and diverse production. The resulting epoxy resin products can be adhered to flat or curved surfaces, or to the human body, enhancing the appearance of objects or the aesthetics of the human body. Users can print various patterns on the printing layer, increasing the uniqueness of the epoxy resin products.

[0025] Optionally, the printing material includes a base layer; the adhesive layer is detachably disposed on the base layer; in step two, when cutting the printing material, the base layer is not cut; after removing waste in step three, the remaining printing layer, the adhesive layer and the ink bonding layer remain on the base layer.

[0026] Optionally, the adhesive layer is a hot melt adhesive layer or a self-adhesive layer, or is formed by a self-adhesive layer and a hot melt adhesive layer. The epoxy product can be applied to an object or human body by cold bonding or hot bonding depending on the properties of the adhesive layer.

[0027] Optionally, the adhesive layer is a self-adhesive layer, and the printing material includes an intermediate layer disposed between the adhesive layer and the ink bonding layer. The intermediate layer is a film of polyurethane (PU), thermoplastic polyurethane (TPU), polyethylene terephthalate (PET), thermoplastic polyester elastomer (TPEE), or hot melt adhesive. The loose structure of the self-adhesive layer and the ink bonding layer lacks support, causing waste material to be difficult to remove. The denser intermediate layer is needed to bond the self-adhesive layer and the ink bonding layer, enabling smooth waste removal.

[0028] To achieve the above objectives, a fourth aspect of the present invention provides an object having an epoxy resin pattern, comprising: An object; and The epoxy resin product described above, or the epoxy resin product prepared by the manufacturing method described above, is adhered to the object with the adhesive layer.

[0029] According to the present invention, an object with an epoxy resin pattern is provided, wherein the epoxy resin product is cold-adheded to the object by the self-adhesive layer or hot-melt adhesive layer. The object can be any item that can be adhered to by the epoxy resin product, such as clothing, hats, cups, various containers, mobile phone cases, iPad cases, electronic products, electrical products, etc., so that the object can be covered with epoxy resin products with different patterns, or that consumers can replace objects with different epoxy resin patterns.

[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.

[0046] This invention provides an epoxy resin product, a method for manufacturing the epoxy resin product and giving the epoxy resin product a pattern, and an object having an epoxy resin pattern. This invention allows consumers or businesses to DIY epoxy resin products with epoxy resin patterns and to adhere the epoxy resin products to objects or the human body, such as to fingernails.

[0047] Figure 1 This is a cross-sectional view of the epoxy resin product 20 (20A) of the first preferred embodiment of the present invention, which includes: a base layer 22, an adhesive layer 24 (24A), an ink bonding layer (or ink absorption layer) 26, a printing layer 28 and an epoxy resin layer 30.

[0048] In this preferred embodiment, the base layer 22, the adhesive layer 24 (24A), and the ink bonding layer 26 are formed of a three-layer inkjet printing paper. The base layer 22, as a carrier layer, can be paper or a polymer material. The adhesive layer 24A in this embodiment is a hot melt adhesive layer, which can be a hot melt adhesive made of polyurethane (PU), polypropylene (PP), thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), polyethersulfone (PES), or ethylene-vinyl acetate copolymer (EVA), etc. It is applied to the base layer 22 by coating or bonding. The base layer 22 can have release properties, making the adhesive layer separable from the base layer.

[0049] The ink bonding layer 26 is disposed on the hot melt adhesive layer 24A, allowing the printer ink to easily bond with it. The ink bonding layer 26 can be a layer of polyurethane resin or acrylic resin, or a resin synthesized from acrylic and polyurethane, but is not limited thereto. In this preferred embodiment, the ink bonding layer 26 is a resin synthesized from acrylic and polyurethane, and its thickness is thin, for example, 0.01~0.1mm. Furthermore, the ink bonding layer 26 contains an appropriate proportion of ink-locking agent (or ink-fixing agent) and leveling agent, etc. The ink-fixing agent prevents the printer ink from spreading, resulting in a clear printed pattern. The ink-fixing agent can be a cationic polyurethane copolymer or a cationic acrylic copolymer, and its addition amount in the ink bonding layer 26 can be ≥2%. The leveling agent smooths the surface of the printed layer 28 and promotes the flowability of the dispensing layer 30 onto the printed layer. The leveling agent can be a silicone-based substance, and its addition amount in the ink bonding layer 26 can be ≥2%.

[0050] Furthermore, the ink bonding layer 26 is opaque, for example, containing one or more white powders such as silica, calcium carbonate, or titanium dioxide, preferably silica, making the ink bonding layer white and blocking the color of other objects. When the epoxy resin product 20A is adhered to an object, the color of the object will not be visible on the epoxy resin product 20A due to the blocking effect of the ink bonding layer 26; the amount of white powder such as silica, calcium carbonate, or titanium dioxide added is approximately 15%.

[0051] The printing layer 28 can be formed by consumers or merchants using home printers such as EPSON, HP, and CANON to print water-based ink onto the ink bonding layer 26. The ink bonding layer 26 can absorb ink (i.e., the ink of the printing layer). The ink can be colored ink, so that the printing layer 28 can print patterns of various colors. The pattern is designed or determined by the printer who prints the printing layer, so it can be various patterns, such as, but not limited to, various texts (such as the English letters A, B, C) or non-texts (such as people, landscapes, animals, plants, symbols, shapes of natural objects, etc.).

[0052] The epoxy resin layer 30 is a layer formed by curing a liquid adhesive, serving as the outer layer of the epoxy resin product 20 (20A), having an appropriate thickness, and enclosing the printing layer 28. Preferably, the adhesive of the epoxy resin layer 30 is a resin synthesized from polyurethane and acrylic, possessing flexible flexibility and good adhesion to the ink bonding layer 26, but this is not a limitation. The adhesive of the epoxy resin layer 30 is a transparent resin containing a photocuring agent (photoinitiator, photocatalyst), which can be cured by ultraviolet (UV) or visible light. The adhesive may also be a transparent resin containing a thermal catalyst, which can be cured by heat. The amount of photocuring agent or thermal catalyst added can be designed according to the required curing time. The cured epoxy resin layer 30 has appropriate flexibility and can bend and flex with curved or arc-shaped surfaces. Preferably, the epoxy resin layer 30 is non-sticky and does not produce stickiness, its surface is dry, and it will not stick to fabric lint after washing. The adhesive layer 30 of this invention increases the proportion of photoinitiators in the resin that promote surface drying. These photoinitiators undergo a chemical reaction upon absorbing light energy of a specific wavelength, generating active intermediates (free radicals or cations). This triggers the polymerization and cross-linking of polymerizable monomers or oligomers in the resin, transforming the liquid adhesive into a solid state. This invention can also increase the cross-linking density of polymerizable monomers or oligomers in the resin, improving the surface drying effect of the adhesive layer 30 and preventing its stickiness. Furthermore, this invention can adjust the flowability of the adhesive, allowing the liquid adhesive to flow outwards and expand rapidly without generating bubbles during the dripping process.

[0053] Figure 2This is a cross-sectional view of the epoxy resin product 20 (20B) according to a second preferred embodiment of the present invention, which also includes: a base layer 22, an adhesive layer 24 (24B), an ink bonding layer 26, a printing layer 28, and an epoxy resin layer 30. The base layer 22, the ink bonding layer 26, the printing layer 28, and the epoxy resin layer 30 are the same as those in the first preferred embodiment, and reference can be made to the description of the first preferred embodiment.

[0054] In this embodiment, the adhesive layer 24B is also a hot melt adhesive, preferably a transparent hot melt adhesive. It further includes an opaque color-blocking layer 25, having a specific color, located between the hot melt adhesive layer 24B and the ink bonding layer 26. Preferably, the color-blocking layer 25 is white and contains components such as silicon dioxide, calcium carbonate, or titanium dioxide. The color-blocking layer 25 can block the color of the object beneath the adhesive layer 24B, so that when the epoxy product 20B is adhered to an object, the front side of the epoxy product 20B will not show the color of the object. The base layer 22, the adhesive layer 24 (24B), the color-blocking layer 25, and the ink bonding layer 26 are formed of a four-layer printing material structure, such as a viscous multilayer material, with the base layer 22 serving as a carrier layer.

[0055] Figure 3 This is a cross-sectional view of the epoxy resin product 20 (20C) of the third preferred embodiment of the present invention, which includes: a base layer 22, an adhesive layer 24 (24C), an intermediate layer 27, an ink bonding layer 26, a printing layer 28 and an epoxy resin layer 30.

[0056] The base layer 22, the adhesive layer 24 (24C), the intermediate layer 27, and the ink bonding layer 26 are formed from a four-layer inkjet printing paper, such as a plurality of adhesive layers. The base layer 22 is a carrier layer. In this embodiment, the adhesive layer 24C is a pressure-sensitive adhesive (PSA). The pressure-sensitive adhesive refers to an adhesive material that is self-adhesive and whose adhesive does not harden or completely lose its adhesiveness after application, such as acrylic adhesives, rubber adhesives, or silicone adhesives, but is not limited thereto. Other adhesive materials that can produce self-adhesiveness that does not completely lose its adhesiveness can be the pressure-sensitive adhesive layer 24C. In this preferred embodiment, an acrylic pressure-sensitive adhesive is used. The pressure-sensitive adhesive layer 24C is applied to the base layer 22 by coating or lamination and is separable from the base layer.

[0057] The intermediate layer 27 is disposed on the self-adhesive layer 24C, located between the self-adhesive layer 24C and the ink bonding layer 26, serving as a bonding medium between the self-adhesive layer 24C and the ink bonding layer 26. The intermediate layer 27 is a thin film, and can be, but is not limited to, materials such as polyurethane (PU), thermoplastic polyurethane (TPU), polyethylene terephthalate (PET), thermoplastic polyester elastomer (TPEE), or hot melt adhesive. In this preferred embodiment, the intermediate layer 27 is a hot melt adhesive made of polyethersulfone (PES). Ethersulfone is a copolyester similar to polyester fiber, exhibiting good adhesion to the ink bonding layer 26 and the self-adhesive layer 24C, and can adhere well to textiles. The self-adhesive layer 24C and the ink bonding layer 26 have a loose structure and lack support. If only the self-adhesive layer and the ink bonding layer exist, it will be difficult to achieve the desired results. Figure 12 During the waste removal process, the waste cannot be completely removed. The intermediate layer 27, which has a denser material structure, is used to bond the self-adhesive layer and the ink bonding layer 26, so that the waste from the self-adhesive layer 24C and the ink bonding layer 26 can be removed smoothly.

[0058] The ink bonding layer 26 is disposed on the intermediate layer 27 for bonding with the ink. The ink bonding layer 26 may be a layer of polyurethane resin or a layer of resin synthesized from acrylic acid and polyurethane. In the preferred embodiment, the ink bonding layer 26 is a resin synthesized from acrylic acid and polyurethane.

[0059] The printed layer 28 is formed by an inkjet printer printing ink onto the ink bonding layer 26. The ink bonding layer 26 can hold the ink printed by the printer, and the printed layer 28 can form patterns of various colors. The patterns are designed or determined by the printer who prints the printed layer, and can be various patterns, such as, but not limited to, various text or non-text.

[0060] The epoxy resin layer 30 is identical to that of the first preferred embodiment, formed by curing a liquid adhesive, and serves as the outer layer of the epoxy resin product 20 (20C), enclosing the printing layer 28. The adhesive is a transparent resin containing a photocatalyst, curable by ultraviolet (UV) or visible light. Alternatively, the adhesive may be a resin containing a thermal catalyst, curable by heat. The cured epoxy resin layer 30 possesses suitable flexibility, allowing it to flex and bend with curved or arc-shaped surfaces. The epoxy resin layer 30 is non-sticky, has a dry surface, and does not attract lint from fabrics after washing. Preferably, the adhesive in the epoxy resin layer 30 is a resin synthesized from polyurethane and acrylic acid, and both the epoxy resin layer 26 and the ink bonding layer contain acrylic acid, allowing for good bonding.

[0061] Figure 4This is a cross-sectional view of the epoxy resin product 20 (20D) according to the fourth preferred embodiment of the present invention, comprising: a base layer 22, an adhesive layer 24 (24D), an ink bonding layer 26, a printing layer 28, and an epoxy resin layer 30. The base layer 22, the ink bonding layer 26, the printing layer 28, and the epoxy resin layer 30 are the same as those in the aforementioned preferred embodiments and can be understood from the aforementioned preferred embodiments. The base layer 22, the adhesive layer 24 (24D), and the ink bonding layer 26 form a plurality of adhesive layers.

[0062] In this embodiment, the adhesive layer 24D is formed by stacking a self-adhesive layer 241 and an intermediate layer, the intermediate layer being a hot melt adhesive layer 242. The hot melt adhesive layer 242 of the adhesive layer 24D is connected to the ink bonding layer 26, and the self-adhesive layer 241 is disposed below the hot melt adhesive layer 242. Preferably, the hot melt adhesive layer 242 is a polyethersulfone (PES) hot melt adhesive, while the self-adhesive layer 241 is an acrylic self-adhesive. When the adhesive layer 24D is heated and pressurized, the self-adhesive layer 241 and the hot melt adhesive layer 242 can be catalyzed and react to produce adhesion. Both the epoxy layer 30 and the ink bonding layer 26 contain acrylic components and can bond well.

[0063] The epoxy resin product 20D can be bonded to objects using either cold or hot adhesion methods. If you do not want the epoxy resin product 20D to be permanently bonded to the object, you can use cold adhesion, attaching the object to the non-drying layer 241. Cold adhesion means that the adhesive layer of the epoxy resin product is directly bonded to the object without heating it. Using cold adhesion, the epoxy resin product 20D can be separated from the object, and the non-drying adhesive layer 241 retains its stickiness, allowing for repeated application. To firmly bond the epoxy resin product 20D to the object, you can press it onto the object. The heat causes a cross-linking reaction between the non-drying adhesive layer 241 and the hot melt adhesive layer 242, generating stickiness and bonding the epoxy resin product to the object. When using hot adhesion, the epoxy resin product will not separate from the object even after washing.

[0064] This epoxy resin product 20 (20A~20D) can be applied to an object 60 or a human body, such as Figures 17 to 20 As shown.

[0065] Figures 9 to 16 , Figure 31 The following describes a preferred embodiment of the invention, which describes a method for manufacturing an epoxy resin product, comprising the following steps.

[0066] Step 1: Prepare a printing material 40 having at least a base layer 22, an adhesive layer 24, and an ink bonding layer 26, and print a patterned printing layer on the printing material 40.

[0067] First, prepare a sheet of printing material 40 of the present invention, which is the inkjet printing paper described above. Figures 5 to 8 These are several printing materials disclosed in this invention, wherein, Figure 5 The printing material 40 (40A) shown is Figure 1 The printing paper of the first preferred embodiment has a base layer 22, a hot melt adhesive layer 24A and an ink bonding layer 26. Figure 6 The printing material 40 (40B) shown is Figure 2 As shown in the preferred embodiment, it has: a base layer 22, an adhesive layer 24 (24B), a color-blocking layer 25 and an ink bonding layer 26. Figure 7 The printing material 40 (40C) shown is Figure 3 As shown in the preferred embodiment, it has: a base layer 22, an adhesive layer 24 (24C), an intermediate layer 27, and an ink bonding layer 26, wherein the adhesive layer 24C is a self-adhesive. Figure 8 The printing material 40 (40D) is Figure 4 The viscous multilayer material described in the embodiment has a base layer 22, an adhesive layer 24 (24D), and an ink-bonding layer 26. The adhesive layer 24D is formed of a self-adhesive layer 241 and a hot melt adhesive layer 242. (The following text and...) Figures 9 to 16 The printing material 40 can be Figures 5 to 8 Any of the printing materials shown, 40A to 40D.

[0068] Next, as Figure 9 As shown, the user uses a home or office printer such as an EPSON / HP / CANON to print a printing layer 28 on the ink bonding layer 26 of the printing material 40. This printing layer 28 can print various patterns 281, including people, animals, non-human / non-animal, text, and other graphics, in monochrome or color, with color being preferred. The user can design the graphics, textures, styles, and colors of the pattern 281 and print it on the printing material 40. The ink-locking agent in the ink bonding layer 26 binds with the ink, preventing ink from spreading and ensuring the pattern 281 is clear and unblurred.

[0069] Step 2: Cut out the pattern 281 of the printing layer 28 from the printing material.

[0070] The pattern 281 of the printed layer 28 can be cut on the printed material 40 by manual cutting or cutting machine cutting. Figure 11 The image shows the printed material 40 being cut using a home or office cutter 52, which is computer-controlled, to cut the printed material 40 according to the outline of the pattern 281. See also... Figure 10The cutting depth D of the cutter 52 is such that it cuts through the ink bonding layer 26 and the adhesive layer 24, but does not cut through the base layer 22. If the printing material 40 is... Figure 6 Printing material 40B or Figure 7 When printing with 40C printing material, its color separation layer 25 or intermediate layer 27 is also cut off.

[0071] Step 3: Remove the portion (waste material) other than the pattern 281 from the printing material, and retain the pattern 281 of the printing layer 28 and the layers superimposed on the pattern on the printing material 40.

[0072] Please see Figure 12 Unnecessary portions of the printed layer 28 other than the pattern 281 are removed, leaving the pattern 281 on the printing material 40. This means removing waste material W that does not include the pattern 281, and retaining the pattern 281 and other layers superimposed on it on the base layer 22. The portions retained on the base layer 22 include: the pattern 281 of the printed layer 28, and the ink bonding layer 26 and adhesive layer 24 superimposed on the pattern 281. The removed waste material W consists of waste material 261 of the ink bonding layer 26 that is not within the pattern 281 and is not bonded to the printed layer 28, and waste material 243 of the adhesive layer 24.

[0073] Please see Figure 13 In this step, when the printing material is Figure 6 The printing material 40B, the portion retained on the base layer 22 includes: the pattern 281 of the printing layer 28 and the ink bonding layer 26, the color separation layer 25 and the adhesive layer 24 superimposed on the pattern 281, and the waste material W to be removed includes the waste material 251 of the color separation layer 25.

[0074] Please see Figure 14 In this step, when the printing material is Figure 7 The printing material 40C, the portion retained on the base layer 22 includes: the pattern 281 of the printing layer 28 and the ink bonding layer 26, intermediate layer 27 and adhesive layer 24 superimposed on the pattern 281, and the removed waste material W includes the waste material 271 of the intermediate layer 27.

[0075] Step 4: Apply adhesive to the printed layer 28 to form an adhesive layer 30 on the printed layer.

[0076] Please see Figure 15 After the pattern 28 is cut, the user holds a dropper bottle and drips liquid adhesive onto the printed layer 28 from the center. After several seconds to minutes, the adhesive spreads evenly and diffuses outwards, forming an adhesive layer 30 on the printed layer 28. Figures 1 to 4As shown, the ink binder layer 26 covers the entire printed layer 28 and its pattern 281. The leveling agent in the ink binder layer 26 can promote the flow and uniform diffusion of the droplet on the printed layer, forming a droplet layer 30 with uniform thickness.

[0077] Step 5: Cure the epoxy resin layer for 30 minutes to form the epoxy resin product.

[0078] Please see Figure 16 After the epoxy resin layer 30 is formed on the printed layer 28, it is cured using a device. In this embodiment, the resin in the epoxy resin layer contains a photocatalyst. The epoxy resin layer 30 is cured by irradiating it with an ultraviolet lamp 54, or by sunlight. This invention increases the proportion of photocatalyst in the epoxy resin, allowing the epoxy resin layer 30 to cure in a short time. Once the epoxy resin layer 30 has cured, the process is complete. Figures 1 to 4 The epoxy resin product 20 (20A~20D). If the resin of the epoxy resin layer contains a thermal catalyst, it can be cured by heat drying.

[0079] The epoxy resin product of this invention can be adhered to an object or human body using this adhesive layer. Please refer to [link / reference]. Figures 17 to 20 After the epoxy resin product 20 is made, the base layer 22 is removed and adhered to the surface of an object 60. Figure 17 and Figure 18 The epoxy resin products 20A and 20B can be bonded to the object 60 by heat treatment through the hot melt adhesive layer 24A or 24B. Figure 19 The epoxy resin product 20C is adhered to the object 60 by the self-adhesive layer 24B. Figure 20 The adhesive layer 24D of the epoxy resin product 20D includes a self-adhesive layer 241 and a hot melt adhesive layer 242. It can be cold-adheded, in which the self-adhesive layer 241 is adhered to the object 60, or hot-adheded, in which the epoxy resin product 20D is pressed onto the object. The self-adhesive layer 241 and the hot melt adhesive layer 242 react with each other through heat to produce adhesion.

[0080] The epoxy resin product 20 of the present invention can be adhered to objects of various materials, giving the object an epoxy resin pattern, namely the pattern 281 of the epoxy resin product. The epoxy resin product is soft and flexible, and can be adhered to flat, curved, or arc-shaped objects. Figures 21 to 26 The epoxy resin products 20 (20A, 20B, 20D) are heat-bonded to objects 60 such as clothing, mobile phone cases, tablet cases, hats, beverage containers (e.g., thermos cups), and cups using the hot melt adhesive layer 24A, 24B, or the adhesive layer 24D. Epoxy resin products 20 (20C, 20D) can be adhered to objects with flat surfaces using the self-adhesive layer 24B or 241, and can also be adhered to objects with curved surfaces, such as fingernails and cups. Figure 27 and Figure 28The epoxy resin product 20B is shown adhering to the nail for nail art. Epoxy resin products 20 (20A~20D) can be adhered to the surface of objects 60 such as electronic or electrical products, for example... Figure 29 As shown, it is adhered to the inner or outer surface of the casing of the notebook computer 60.

[0081] Figure 30 The epoxy resin product 20 may be any one of the epoxy resin products 20 (20A~20D) of the first to fourth preferred embodiments.

[0082] This embodiment further adds an additive 32 to the resin of the epoxy resin layer 30, so that the epoxy resin layer 30 after molding contains the additive 32. The additive can be, for example, but not limited to, glitter powder, phosphorescent powder, reflective powder, thermochromic powder, photochromic powder, pearlescent powder, etc., so that the transparent epoxy resin layer 30 provides other effects in addition to aesthetics. The glitter powder gives the epoxy resin layer 30 of the epoxy resin product 20 a shiny effect; the phosphorescent powder (phosphorescent particles) makes the epoxy resin layer 30 glow at night or in dim light; the reflective powder (reflective particles) makes the epoxy resin layer 30 reflect light at night or in dim light; the thermochromic powder makes the epoxy resin layer 30 change color due to temperature changes; the photochromic powder makes the epoxy resin layer 30 change color due to changes in light intensity; the pearlescent powder makes the epoxy resin layer 30 reflect light with multiple colors.

[0083] In step four of the aforementioned preparation method, the dispensing resin contains at least one of the aforementioned additives.

[0084] The adhesive in the epoxy resin layer of the present invention is directly applied to the printing layer 28 and bonds well with the printing layer 28. There is no coating or treatment agent between the epoxy resin layer 30 and the printing layer 28, and the epoxy resin layer 30 will not detach or separate. Therefore, the epoxy resin product of the present invention is washable and dryable, and can be used on items that need to be washed, such as clothing.

[0085] The printing material of this invention provides an ink bonding layer (ink-absorbing layer) on which ink can be directly printed without ink bleeding, resulting in a clear printed pattern. Consumers can use the printing material of this invention to print patterns and create epoxy resin products.

[0086] The epoxy resin products 20 (20A~20D) provided by this invention can be made into various patterns by users or consumers to meet consumers' customization needs and DIY creativity, and make the patterns of epoxy resin products unique, one-of-a-kind and varied.

[0087] The epoxy resin products of this invention allow users or businesses to make them at home, enabling small-batch and diversified production without worrying about production quantity or using molds. All that is needed is the printing material of this invention, and by using a home printer, cutter, dropper, light curing machine, or heat oven, one can DIY epoxy resin products of various sizes and patterns.

[0088] The epoxy resin product of the present invention can be hot- or cold-bonded to various objects or articles, including the surface of the human body, increasing the versatility of its use and enhancing the appearance of the article or the aesthetic appeal of the human body.

[0089] The printing layer of the present invention is printed with ink. Through the leveling agent of the ink bonding layer, the liquid adhesive can flow well and spread evenly on the printing layer to form a uniform adhesive layer.

[0090] This invention solves the problem that only industrial-scale technology can produce epoxy resin products, allowing consumers to use a printer to create various patterns and manufacture epoxy resin products. These epoxy resin products 20 are then adhered to various objects 60 to create objects with epoxy resin patterns. Users can replace different epoxy resin products to change the epoxy resin patterns. Taking a mobile phone or iPad case as an example, if the epoxy resin product 20 is cold-attached to the case, the user can remove the old product and attach a new one to change the epoxy resin pattern. If the epoxy resin product 20 is heat-attached to the case, phone cases with different epoxy resin patterns can be used, allowing the phone to have different epoxy resin patterns.
