Description

[Detailed explanation of the invention] This invention is a vapor-deposited transfer foil.
For example, the present invention relates to a vapor-deposited transfer foil for decorating the surface of a plastic molded article with a metal foil having a so-called grain pattern.

As shown in FIG.
For example, a decorative product in which a metal foil with a so-called grain pattern 9 formed on the surface of which is matted by fine granular irregularities is closely adhered to the surface of a plastic molded product 8 is a decorative product containing a decorative material. It is prized for enhancing the beauty of containers and other items.

Conventional methods for making such decorative products include transferring vapor-deposited transfer foil of only the selected metal color onto the surface of a plastic molded product in advance, and pressing it with a metal plate having a desired grain pattern; A known method is to use gravure printing to print a desired grain pattern onto a mat to make transfer foil, but the former method requires a separate template to press the grain pattern, which is complicated and costly. The latter method also has some inconveniences, such as the need to make a gravure printing plate, which increases the cost accordingly.

This invention eliminates such conventional inconveniences and provides a new vapor-deposited transfer foil that can easily form a textured pattern with a beautiful finish on the surface of a plastic molded product at low cost.

Next, an embodiment of this invention will be described with reference to FIG. The substrate 1 is, for example, a synthetic resin film such as polyethylene terephthalate, polyester, polypropylene, polyethylene, or polycarbonate, or a sheet such as polyolefin coated paper, and if necessary, an appropriate undercoat 2 having high affinity with the substrate is applied. For example, a thermosetting resin paint such as thermosetting acrylic, silicone paint, or epoxy resin paint, or a thermoplastic paint such as PVC or acrylic is applied, and then an ultraviolet curing pseudo is applied in the shape of a planar figure with the desired grain pattern. Has an etching effect. The matte etching ink layer 3 is formed to form, for example, a lattice pattern shown in FIG. 3, in which case the matte etching ink layer 3 is formed in a lattice pattern in plan view.

Next, a matte etching ink layer 3 is applied, such as thermoplastic acrylic resin, wax, etc.
A release layer 4 made of a material such as polyethylene, ethylene-vinyl acetate copolymer resin, or polyvinyl alcohol is provided.

On the peeling layer 4, a colored layer 5 is provided when it is desired to color a desired grain pattern or to print a colored pattern, characters, symbols, etc. separately from this. The colored layer 5 is made of natural and synthetic resins commonly used in ink coating materials, such as cellulose resins such as ethyl cellulose and nitrocellulose, acrylic resins, styrene resins, chlorinated rubber, cyclized rubber, and vinyl chloride-vinyl acetate copolymer. The ink is composed of a color vehicle appropriately selected from resins, polyamide resins, petitral resins, melamine resins, etc., and an oil-based dye mixed therein as a colorant.

On this colored layer 5, a metal vapor deposition layer 6 made of aluminum or the like is provided, and on top of this, acrylic, styrene, rosin, rubber, polyamide, modified products thereof, or their modified forms are coated with water. An adhesive layer 7 made of a thermoplastic resin such as a dispersed emulsion type resin is provided.

The transfer foil having the structure detailed above is placed so that its adhesive layer 7 is in contact with the target plastic molded article 8, and when it is heated and transferred from above in the direction of the arrow, it peels off as shown in FIG. Layers 4 and below remain attached to the plastic molding 8. When viewed from above, the metal vapor deposited layer 6 represents a photosensitive surface unique to the metal, and the concave portion corresponding to the matte etching ink layer 3 expresses the desired matte grain pattern 9 in the photosensitive surface. be. As already mentioned, this grain pattern 9 is created by the colored layer 5.
can be expressed in color, and in addition to this grain pattern, characters, symbols, patterns, etc. can also be expressed by this colored layer 5. In some cases, this colored layer may be completely omitted.

According to this invention, the following effects are achieved.

a A precise pattern in the shape of a desired grained planar figure can be easily formed on a substrate by a matte etching ink layer having an ultraviolet curing type pseudo etching effect, and the pattern formed in this way can be easily formed. Precise patterns can be accurately and reliably transferred onto molded objects because the matte etching ink layer is cleanly peeled off from the release layer by the action of the undercoat during heat transfer. A grain pattern with a precise pattern can be made to appear beautifully, and a grain pattern with higher decorativeness can be obtained.

b By adding a colored layer, the grain pattern itself can be colored, and characters, symbols, patterns, etc. can be expressed separately independently of the grain pattern, so the synergistic effect combined with the above effects makes it even more appealing. A highly decorative grain pattern can be obtained.

c In the process of forming the grain pattern, there is no need to separately make a template for pressing the grain pattern or a plate for gravure printing, so the highly decorative grain pattern can be easily formed on the surface of the plastic molded product at low cost. be able to.
