Description

Decorative element and method of making the same

technical field

The present invention relates to a decorative element and a manufacturing method thereof, and in particular to a decorative element with a holographic pattern and a manufacturing method thereof.

Background technique

Credit cards, banknotes, checks and other important documents need to have specific signs or characteristics to avoid being copied or embezzled. Today's copying equipment and copying technology are constantly improving, so new anti-counterfeiting technology must be developed. A hologram is a diffractive optical element that is widely used for authentication, security, defense or similar purposes. For example, the holographic pigeon image on the credit card and the holographic spherical image are designed for these purposes.

The reason for using holographic technology to achieve anti-counterfeiting purposes is that holographic images cannot be copied by scanning or printing, and it is not easy for those who are familiar with holographic technology to forge in the form of holographic images. At present, the application method of the holographic pattern is to make the holographic pattern on paper or film to form a required label or sign. Then, a label or logo with a holographic pattern is pasted on the surface of the element as an anti-counterfeiting design.

However, the adhesive material used for pasting may deteriorate due to weathering, oxidation or other effects, so the label or mark attached to the component has poor reliability and is easily peeled off from the surface of the component. In addition, the way of attaching may also make the structure constituting the holographic image easy to be worn or scratched and lose its visibility.

1A to 1E illustrate a method for manufacturing a decorative element according to an embodiment of the present invention. Please refer to Fig. 1A first, form a release layer 122 on a base material 110, wherein the formation method of release layer 122 can be to carry out a coating process so that a release type (transparent) material is coated on the base material 110 . In this embodiment, the material of the substrate 110 can be polyethylene terephthalate (polyethylene terephthalate, PET), polyethylene naphthalate (polyethylene naphthalate, PEN), glycol-modified polyethylene terephthalate Dicarboxylate (polyethylene glycol-co-cyclohexane-1, 4dimethanol terephthalate, PETG), thermoplastic polyurethane (thermalplastic polyurethane, TPU), polyurethane (polyurethane, PU), polypropylene (polypropylene, PP), polypropylene Carbonate (polycarbonate, PC), amorphous polyethylene terephthalate (amorphous polyethylene terephthalate, APET), polyvinyl chloride (polyvinyl chloride, PVC), polystyrene (Polystyrene, PS) cellulose triacetate ( Polymer materials such as triacetyl cellulose (TAC), acrylic (polymethylmethacrylate, PMMA), styrene-methyl methacrylate copolymer (MMA-St, MS) or cyclo olefin polymer (COC), or Can be composed of two or more of the above polymer materials, etc., but not limited thereto. In addition, the base material 110 is a flexible material to facilitate subsequent processes.

The release layer 122 can be a transparent resin material with heat curable property or ultraviolet light curable property. The release layer 122 is usually a low surface tension film made of one of materials such as wax, paraffin or polysiloxane, or a highly smooth and impermeable film made by such as radiation-resistant Prepared from one of cured polyfunctional acrylates, silicone acrylates, epoxies, vinyl esters, allyls and vinyls, unsaturated polyesters, or mixtures thereof. The material of the release layer 120 may comprise a condensation polymer, a copolymer, a mixture selected from the group consisting of epoxy, polyurethane, polyimide, polyamide, melamine formaldehyde, urea formaldehyde, and phenol formaldehyde or compound.

Next, referring to FIG. 1B , a pattern transfer process such as an embossing process is performed on the release layer 122 . During the embossing process, a roller 10 with a plurality of raised patterns 12 is used to contact and press on the release layer 122 to transfer the raised patterns 12 to the release layer 122 to form a concave-convex structure 124 . In this embodiment, the concave-convex structure 124 is located on a side of the release layer 122 away from the substrate 110 . It should be noted that the raised pattern 12 is produced according to the optical interference fringes of a predetermined image, and may have two or more reflective surfaces, and is not limited to the form shown in FIG. 1B . In addition, the roller 10 shown in FIG. 1B can be replaced by a flat plate with a raised pattern 12 to transfer the optical interference fringes of the preset image to the release layer 122 .

Specifically, the embossing process may be a hot pressing process or other processes used in the field, but the present invention is not particularly limited. That is to say, the method of forming the concave-convex structure 124 is not limited to the manufacturing steps shown in FIG. 1B . In addition, the release layer 122 can be cured by heating or irradiating ultraviolet light to provide a fixed pattern. In one embodiment, the thickness of the release layer 122 is substantially 1 μm to 30 μm.

Afterwards, as shown in FIG. 1C , a reflective layer 126 is formed on the concave-convex structure 124 to form a holographic layer 120 . The method of forming the reflective layer 126 may be an evaporation process or a sputtering process. The reflective layer 126 is substantially conformal to the concave-convex structure 124 so that the light reflected by the reflective layer 126 can present a holographic image through interference. Therefore, the concave-convex pattern 124 and the covering reflective layer 126 define a plurality of holographic patterns H in the holographic layer 120 . In one embodiment, a material of the reflective layer 126 can be aluminum, copper, nickel, zinc, chromium, silver, titanium, tungsten, gold, platinum, tin, magnesium, metal oxides, alloy oxides or combinations thereof ethnic group.

After that, referring to FIG. 1D and FIG. 1E , an adhesive layer 130 is formed on the reflective layer 126 and the holographic layer 120 is attached to the body 140 of an element 100 . The material of the adhesive layer 130 can be made of such as polyacrylate (polyacrylate), polymethacrylate (polymethacrylate), polystyrene (polystyrene), polycarbonate (polycarbonate), polyurethane (polyurethane), polyester (polyester), polyester Polyamide, epoxy resin, ethylene vinyl acetate copolymer (EVA, ethylene vinyl acetate), thermoplastic elastomer (thermoplastic elastomer) or similar, or its copolymer (copolymer), mixture (blend) or one of the composite materials. In particular, the substrate 110 can then be removed to form the element 100 with the holographic layer 120 . It is worth mentioning that the hologram pattern H is sandwiched between the release layer 122 and the main body 140 . Therefore, the hologram pattern H is not easily damaged and has ideal reliability.

In this embodiment, the method of forming the body 140 of the element 100 may be a decoration process, and the steps of the decoration process are described as follows. Firstly, the base material 110 and the holographic layer 120 disposed thereon are placed in an unshown mold. In this step, the mold may be a mold tool for making the body 140 . Then, a body material is filled into a mold not shown, and then the body 140 and the holographic layer 120 are ejected from the mold not shown. At this time, the substrate 110 can be separated from the hologram layer 120 while the body 140 and the hologram layer 120 are shot out from a mold not shown. In addition, in other embodiments, the substrate 110 may also be separated from the hologram layer 120 after the body 140 and the hologram layer 120 are shot out of a mold not shown.

The process carried out according to the above process steps can be called an in-mold decoration process. In one embodiment, the body material in the above steps can be a plastic material, such as polycarbonate (polycarbonate, PC), polypropylene (polypropylene, PP), acrylic (polymethylmethacrylate, PMMA), styrene methacrylic acid Methyl ester copolymer (MMA-St, MS), acrylonitrile butadiene styrene (ABS), polystyrene (polystyrene, PS), polyethylene terephthalate (polyethylene terephthalate) , PET) and polyoxymethylene (POM), but not limited thereto. Moreover, the above process steps can be performed according to a conventional injection molding process. However, the decoration process of this embodiment is not limited to the above-mentioned manufacturing steps. For example, the decoration process can be an in-mold rolling process, a laminating process, a thermoforming process (thermoforming), a blow molding process (blowmolding), a stamping process (stamping process), a compression molding process (compression molding), a combination of the above processes to bond the holographic layer 120 to the body 140 of the element 100 .

In this embodiment, the body 140 of the element 100 is provided with a hologram layer 120 , and the hologram pattern H is sandwiched between the release layer 122 and the adhesive layer 130 . Therefore, the hologram pattern H can be protected from being scratched or damaged. In this way, after the element 100 has been used for a period of time, the holographic pattern H still maintains a clear and sharp appearance and is easy to recognize. If the holographic pattern H is used as the anti-counterfeiting mark, it can provide an ideal and reliable anti-counterfeiting function. In addition, the holographic pattern 120 of this embodiment is combined with the main body 140 through a decoration process, so the holographic pattern 120 conforms to a surface 142 of the main body 140 . Also, no matter what the shape of the body 140 is, the hologram pattern 140 can be formed on the surface 142 thereof. That is to say, the hologram pattern 120 can be closely attached to any surface, such as a curved surface, a rough surface or a sharp surface, so that the practicability of the hologram layer 120 is greatly improved. Therefore, the element 100 with the holographic pattern H can have various designs.

2A to 2D illustrate a method of manufacturing a decorative element according to another embodiment of the present invention. Referring to FIG. 2A , in this embodiment, a release layer 222 a , a durable layer 222 b and a reflective layer 126 are sequentially formed on the substrate 110 . The substrate 110 may be a PC substrate, a PET substrate, or a substrate made of the materials described in the above-mentioned embodiments. A material of the reflective layer 126 can be aluminum, copper, nickel, zinc, chromium, silver, titanium, tungsten, gold, platinum, tin, magnesium, metal oxide, alloy oxide or a group thereof. Here, the release layer 222a is used to temporarily bond the durable layer 222b and the substrate 110 , and will be separated from the durable layer 222b in subsequent processes. The durable layer 222b can be, for example, a heat-curable material or a UV-curable material. Generally speaking, the material of the release layer 222a is, for example, siloxane or silica gel to provide a temporary bonding effect. In an embodiment, the thickness of the release layer 122 may be 1 μm to 30 μm.

Subsequently, referring to FIG. 2B , a pattern transfer process is performed on the substrate 110 to form a holographic layer 220 . In this step, a concave-convex structure 224 is formed on a surface (not shown) of the durable layer 222b, and the reflective layer 126 is conformal to the concave-convex structure 224 . Specifically, the pattern transfer process may be a general imprinting process, a hot embossing process, or the like. Similar to the embossing process of the previous embodiments, a plate or a roller with a plurality of raised patterns is also used to transfer the patterns in this embodiment, wherein the raised patterns are based on optical interference of a predetermined image Made of stripes. In other words, the concave-convex structure 224 and the reflective layer 126 covering it together form a plurality of holographic patterns H. Referring to FIG.

Next, referring to FIG. 2C and FIG. 2D , an adhesive layer 130 is formed on the holographic layer 220 and a decoration process is performed to complete the device 200 shown in FIG. 2D .

That is, the substrate 110 provided with the release layer 222a, the holographic layer 220 and the adhesive layer 130 can be placed in a mold, and a hot-melt plastic material is injected into the mold to perform the decoration process. In this way, the holographic layer 220 can be closely disposed on a surface 142 of a body 140 of the element 200 . Subsequently, an injection process is performed to inject the body 140 and separate the release layer 222 a from the holographic layer 220 . It is worth mentioning that the disposition of the release layer 222 a helps to separate the substrate 110 from the holographic layer 220 in this embodiment. In particular, the element 200 can be formed by performing an in-mold transfer process to bond the holographic layer 220 to the body 140 .

In this embodiment, the decoration process helps to tightly bond the holographic layer 220 to the surface 142 of the body 140 through the adhesive layer 130 so that the holographic layer 220 has good reliability. In one embodiment, the holographic layer 220 can be embedded in the main body 140 through a decoration process, and the holographic pattern H is sandwiched between the durable layer 222 b and the main body 140 . Therefore, the hologram pattern H is not easily scratched or damaged. Furthermore, the holographic layer 220 is conformal to the surface 142 of the body 140 such that the surface 142 can be a planar or a non-planar. On the whole, compared with the existing design of attaching a paper with a holographic pattern on a flat surface of a component, the design of this embodiment helps to improve the design diversity of the component 200, and this embodiment The holographic layer 220 of the embodiment has better reliability.

In other embodiments, the reflective layer 126 may be partially formed on the substrate 110 to form a partial holographic pattern. In particular, FIGS. 3A to 3D illustrate a method of manufacturing a decorative element with a partial holographic pattern.

Referring to FIG. 3A , a substrate 110 and a light-transmitting bottom layer 322 disposed thereon are provided. Here, the light-transmitting bottom layer 322 can be fabricated by the process described above to have a concave-convex structure 324 . In addition, a release layer (not shown) can be disposed between the transparent bottom layer 322 and the substrate 110 , as shown in FIG. 2B , or the transparent bottom layer 322 itself is a release layer.

In addition, in this step, a mask layer 350 is formed on the light-transmitting bottom layer 322 to shield a part of the surface of the light-transmitting bottom layer 322 . The material of the mask layer 350 may be a polymer material, including polyurethane, polymethylmethacrylate (PMMA), epoxy resin, polyester, or a combination of the above materials. In addition, a reflective material layer 326' is formed on the substrate 110 by an evaporation process or a sputtering process. In this embodiment, the reflective material layer 326' conformally covers another part of the surface of the transparent bottom layer 322 exposed by the mask layer 350 and covers the mask layer 350, for example.

Then, referring to FIG. 3B , the mask layer 350 is removed to form a reflective layer 326 partially exposing the light-transmitting bottom layer 322 . In this embodiment, the reflective layer 326 and the concave-convex structure 324 form a plurality of holographic patterns H together. The reflective layer 326 is partially disposed on the substrate 110 so that the holographic pattern H is partially disposed in the holographic layer 320 .

Next, referring to FIG. 3C and FIG. 3D , an adhesive layer 130 is formed on the hologram layer 320 , and the decoration process described in the above embodiments is performed to form an element 300 , which has a body 140 and a hologram layer on the surface of the body 140 320. This embodiment is similar to the above embodiments, the holographic layer 320 can be disposed on the main body 140 through the adhesive layer 130 . However, in this embodiment, the hologram pattern H is only partially distributed on the surface of the main body 140 , which helps to improve the design diversity of the main body 140 .

In addition to the holographic pattern, other decorative patterns, such as ink patterns, can also be formed on the surface of the element, and the corresponding manufacturing methods are shown in FIG. 4A and FIG. 4B , for example. 4A and 4B illustrate a partial process of a decorative element according to another embodiment of the present invention. Referring to FIG. 4A , a substrate 110 and a holographic layer 420 disposed thereon are provided. The holographic layer 420 here may be the holographic layer 120 , 220 or 320 described in the foregoing embodiments. That is, the holographic layer 420 is produced through the process described above, and a release layer (not shown) can be selectively disposed between the substrate 110 and the holographic layer 420 (ie, as shown in FIG. 2B). In addition, an ink layer 460 is formed on the holographic layer 420, wherein the ink layer 460 can be a color ink layer, a black ink layer, or a white ink layer to form a desired ink pattern.

Next, please refer to FIG. 4B , the hologram layer 420 and the ink layer 460 are bonded on a body 140 of an element 400 through a decoration process. Specifically, the hologram layer 420 and the ink layer 460 are attached to the main body 140 through an adhesive layer 130 .

Additionally, the element 400 may be subjected to an in-mold decoration process to bond the holographic layer 420 and the ink layer 460 to the body 140 . In other embodiments, the film with the holographic layer 420 and the ink layer 460 can be pasted on the body 140 by hot stamping, lamination or thermal transfer to form the element 400 . Therefore, the element 400 has both the holographic pattern H and the ink pattern.

The holographic pattern H of the holographic layer 320 is locally distributed on the surface of the body 140 , so that the ink layer 460 can be exposed between the concave-convex structures 324 not covered by the reflective layer 326 . Therefore, the holographic pattern H and the ink layer 460 can constitute a composite holographic pattern C as shown in FIG. 5B . When viewing the composite hologram C, the user can see the partial hologram H and the partial ink layer 460 . However, the relative position and area size of the holographic pattern H and the ink layer 460 can be adjusted according to the designer's requirements to form the required composite holographic pattern C, and FIG. 5B is only used to illustrate but not limit the present invention.
