JPS588774A - Pressure-sensitive decorative adhesive label or sheet - Google Patents

Abstract

PURPOSE:To provide the titled label or sheet showing a stereoscopic effect and variation of lightness by irregular reflection, prepared by laminating a plastic film with (semi)transparent uneven patterns on the surface of a metallic colored label or sheet backed with a pressure-sensistive adhesive layer by using a (semi)transparent adhesive. CONSTITUTION:The label or sheet is prepared by laminating a (semi)transparent plastic film 3 (e.g. polyethylene, or polypropylene) with numerous unevennesses of at least 5M deep formed by means of an embossing roller, etc. on the surface of a metallic colored label or sheet made of (a) base sheet 1 consisting of a (semi)transparent plastic film 1a and a deposited metal film (e.g., aluminum) 1b, (b) a pressure-sensitive adhesive layer 6 and (c) a release paper 7, by using a (semi)transparent adhesive 4 (e.g., acrylic ester). The decorative label or sheet has a stereoscopic and substantial appearance with complicated color variation.

Description

DETAILED DESCRIPTION OF THE INVENTION Decorative pressure-sensitive adhesive labels or sheets with a smooth metal-colored decorative surface, with or without printing on the surface, have been known in the art, but the surface has a smooth and monotonous metal surface in appearance. It is extremely difficult to process such a type of label or sheet into something with a three-dimensional effect that has an uneven pattern all over it. That is, even if the surface is subjected to sandblasting or brushing, the scratches are shallow and no uneven pattern is formed on the surface. Furthermore, when applied to an embossing roller or the like, depending on the material, the flexible base material itself tends to be cracked or damaged, making it difficult to commercialize it.

Regardless of the material of the label or sheet base material, the present invention provides an uneven pattern with a three-dimensional appearance and uneven brightness due to diffused reflection without damaging the label or sheet base material, and protects the printed surface well. To easily provide a new type of decorative pressure-sensitive adhesive label or sheet, which has a pressure-sensitive adhesive coating layer on the back surface of a metal-colored label or sheet base material with a difference in unevenness of 5μ or more. It is characterized by a transparent or translucent plastic film laminated with a myriad of uneven patterns and attached via a transparent or translucent adhesive.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In the drawing, (1) indicates a label or sheet base material having a metallic color, and the base material (1) is a metal-deposited plastic film or metal foil in which a metal-deposited surface is formed on one side of a transparent or translucent plastic film. , metal-foil paper made of a laminate of paper and metal foil, metal-deposited paper in which a metal-deposited surface is formed on paper, and the like. The one shown is a label with a surface-enhancing metallic color, which is made by integrally forming a colorless transparent or translucent plastic film base material (1a) and a vapor-deposited film (1b) of aluminum or other metal on the layer surface. Sheet base material (
An example using 1) is shown below. A transparent or semi-transparent flexible and tough plastic film A having an uneven pattern (2) with a difference in unevenness of at least 5 μm on the surface of this base material (1), which is separately processed by an embossing roller or drawing process, etc. +31 is pasted through a transparent or translucent adhesive coating layer (4).In such a case, the base material (1 The metal surface (metal deposited surface) of ) is provided with a heavy metal decorative surface processed into a three-dimensional metal surface with an uneven pattern (2).Also, in this case, at the same time, the transparent film (3)
The uneven pattern (2) diffusely reflects light, giving the appearance of a complex metal surface with brightness and darkness, and printing appropriate characters, figures, etc. on the surface of the base material (1) [[]] (51 Generally, the printed surface (5) has a three-dimensional appearance with complex brightness and darkness through the uneven film (3), which improves its taste.The uneven pattern The shape of (2) is arbitrary. In the illustrated example, the seam is made up of countless straight grooves and protrusions, and the difference between the unevenness is 5μ or more.
Preferably, nine uneven patterns (2) of about 50 μm to 100 μm are formed over the entire surface of the film (3) at a density of 10 to 1000 lines/cIrL in the width direction. This is an example of a product having a three-dimensional metal surface with an uneven pattern according to the present invention constructed in this manner. This figure shows a release mount temporarily pasted on its outer surface and coated with a release agent such as silicone resin.

The material of the plastic film (3) having the transparent or translucent uneven pattern is selected from suitable synthetic resin films such as polyethylene, polypropylene, polyester, and vinyl chloride, and is stretched to a thickness of 5 to 200 μm. As the transparent or translucent adhesive (4), pressure sensitive adhesives such as acrylic ester adhesives and rubber adhesives are particularly preferred.

FIG. 5 shows a modification in which a metal foil (1) is used as the base material instead of the transparent or translucent plastic metal vapor deposited base material. The metal foil used has a thickness of about 5 μm to 100 μm.

Although not shown, a label or sheet base material may be made by forming a metal foil or a metal vapor-deposited film on the surface of paper or coated paper. The thickness of the metal vapor deposited film may be in the range of 0.05 to 0.1 micron.

In the case of the practical example shown in FIG. 5 of the present invention or an embodiment using a base material having a metal foil or metal vapor deposited film on the surface, the plastic film having the uneven pattern (2) of the present invention ( 3), the film (3) gives the metal surface an uneven appearance, and at the same time protects the metal surface and the printed surface appropriately from deterioration caused by rainwater, etc. Helps protect from impact, friction, etc.

In this way, according to the present invention, a separately prepared transparent or translucent Plasti Thick 7' ilm with an uneven pattern is attached to the surface of a label or sheet base material whose decorative surface is a metallic color. With this method, decorative adhesive labels or sheets with a three-dimensional appearance of an uneven pattern and a complex gold-tone surface due to diffused reflection can be obtained extremely easily, and regardless of the material of the label base material, it will not be damaged. It has the effect that various products can be obtained without giving any.
