SUMMARY OF THE INVENTION The present invention relates to a decoration in which a matte tone region is formed on a pattern ink layer and a metal deposition layer, and a metallic gloss region is formed on the outermost surface by a highly glossy metal foil layer. It is intended to provide an effective packaging material.

[0010]

According to the present invention, there is provided a synthetic resin layer 1 comprising:
1, a metallized layer 12, a pattern ink layer 13, a transparent synthetic resin layer 14, a mat resin layer 15, and a patterned metal foil layer 16 are laminated in this order.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to embodiments.
FIG. 1 is a side view of a packaging material according to the present invention, in which a synthetic resin layer 11 (polyester, polyethylene, polypropylene,
A metal vapor-deposited layer 12 such as aluminum is applied to the surface of a film sheet made of polyvinyl chloride, acrylic, or a composite material thereof.

On the metal-deposited layer 12 side of the synthetic resin layer 11,
After applying the pattern ink layer 13 by an appropriate printing method, a transparent synthetic resin layer 14 is applied to the entire surface of the pattern ink layer 13 side. On the transparent synthetic resin layer 14, a mat-like synthetic resin layer 1 is formed.
5 is applied, and a metal foil layer 16 is applied on the resin layer 15.

The metal deposition layer 12 is made of a metal such as aluminum and has a thickness of 1 × 10 ⁻⁴ μm to 1 × 1.
The entire surface of the synthetic resin layer 11 or a pattern is deposited at 0 ^-1 μm.

The pattern ink layer 13 has a suitable pattern, character, or color printed by a gravure printing method, an offset printing method, a screen printing method, or the like, and uses a printing ink having an appropriate color tone.

The transparent synthetic resin layer 14 is formed by coating or coating a liquid or molten transparent synthetic resin by an extruder method, or by laminating a transparent synthetic resin film.
Any of the same materials as those described above or the resin used for the synthetic resin layer 11 can be used.

The mat-like resin layer 15 is made of a mat-like synthetic resin obtained by adding an appropriate amount of a matting agent such as a silica-based or kaolin-based resin to an olefin-based or alkyd-based synthetic resin, or the above-mentioned olefin-based or alkyd-based resin. Varnish to which a wax agent such as a silica-based or kaolin-based matting agent and a wax are added can be used.

The metal foil layer 16 is formed on the outermost surface. A metal foil sheet for heat transfer is superimposed on the mat varnish layer 15, and an appropriate pattern mold heated from above is pressed. The pattern is appropriately applied by a heat transfer method, and is provided with a metallic high gloss area, for example, a pattern with a relatively delicate line drawing such as a brand name of a confection, a name of a cosmetic soap or a cosmetic. A high gloss region (metal foil layer 16) is formed by heat transfer of the metal foil sheet for heat transfer.

FIG. 2 is a side view of the metal foil sheet for heat transfer, showing a transfer base sheet 2 made of polyester resin.
1, a metal deposition layer 23 of aluminum or the like is applied via a release agent layer 22, and an adhesive layer 24 is applied to the metal deposition layer 23.

The release agent layer 22 is a release agent having a composition mainly composed of a resin exhibiting easy releasability to either the transfer base sheet 21 or the metal deposition layer 23. For example, a material mainly composed of silicone resin can be used.

FIG. 3 is a side view for explaining another embodiment of the packaging material of the present invention. A mat-like resin layer 15 is provided on a transparent synthetic resin layer 14 in a pattern. A metal foil layer 16 made of aluminum or the like is provided in an appropriate pattern on the substrate 15 by a heat transfer method.

When the metal foil layer 16 is made of aluminum, the metal foil layer 16 has a strong metallic luster of silver color.
The surface of the silver-colored metal foil layer 16 can be appropriately colored with a coloring ink as needed. For example, a yellow ink (preferably a transparent ink) is used to such an extent that the glossiness of the glossy surface is not reduced. By laminating thinly, the surface becomes the metal foil layer 16 having a golden color tone.

When manufacturing the packaging material of the present invention, in addition to the above-described manufacturing method, for example, a synthetic resin layer 11 (synthetic resin film) having a metal vapor-deposited layer 12 on one side and a pattern ink layer 13. On the other side, mat-like resin layer 15
And a transparent synthetic resin layer 1 provided with a metal foil layer 16 on its upper surface.
4 (transparent synthetic resin film) may be laminated by a dry lamination method via an adhesive as appropriate.

The metal deposition layer 12 of the synthetic resin layer 11
On the opposite side, a suitable synthetic resin film having suitability for a sealant may be separately attached by a dry lamination method via an adhesive.

Specific examples will be described below. <Example 1> A transparent biaxially stretched polypropylene film (OPP, for example, having a thickness of 20 µm) having a corona treatment on both surfaces.
１００100 μm) on a printing substrate (transparent synthetic resin layer 1)
As 4), an arbitrary pattern layer (a pattern ink layer 13 formed by a combination of a solid shape and a pattern shape) is printed in a single layer or a multilayer shape as appropriate with a urethane-based ink. Subsequently, a mat-like varnish (mat-like resin layer 15) having a composition of a polyamide-based synthetic resin + a silica-based matting agent + wax is printed in an arbitrary pattern on the surface of the printing substrate. Then, the pattern layer side of the printing substrate, the vapor deposition side of a polyethylene terephthalate resin film on which aluminum has been vapor-deposited (the synthetic resin layer 11 on which the metal vapor-deposited layer 12 has been deposited), and a sealant film (for example, polyethylene, unstretched polypropylene, etc.) Are sequentially superposed and laminated to obtain a packaging material having a metallic glossy region having a partial matte feeling. Subsequently, a metal foil sheet for heat transfer is superimposed on the matt varnish side of the printing substrate, and a metal mold for foil pressing of an arbitrary pattern, for example, is heated and pressed by a metal mold having a relatively fine character pattern. Forming a highly glossy metal foil character pattern on the matt varnish surface of the printing substrate. As a result, a high-quality packaging material in which a character pattern of a highly glossy metal foil, a matte (soft) metallic luster area, and a matte (soft) picture area are formed is obtained.

High gloss area on the surface (metal foil layer 1
6) any one of a soft gloss region by the metal deposition layer 12 and the mat resin layer 15 and a soft pattern region such as a soft pattern region, a soft coloring region, a soft character region by the pattern ink layer 13 and the mat resin layer 15. The regions are observed as being mixed and integrated with each other, which further enhances the decorative effect.
