2. Description of the Related Art Conventionally, a label having a plurality of colored aluminum foils formed on its surface has been known. This label is foil-stamped in a plurality of colors by stamping a plurality of pre-colored transfer foils onto the label base one by one. In addition, a partial vapor deposition method or the like is used as a method of partially producing a metallic feeling.

[0003]

However, in the conventional thin adhesive sheet, in order to give different metallic lusters to the plurality of foils transferred to the label base, only the number of colors to be transferred is required. Since a transfer foil is required and a mold for transferring the foil is also required for each transfer foil, a great deal of labor and equipment are required.

Further, in order to perform gradation printing with a metallic luster, there is a method of printing a portion which is difficult to be vapor-deposited in advance before vapor deposition and washing unnecessary portions after vapor-depositing the whole surface, but the process is complicated. It could only be used for specific purposes. Therefore, it was impossible to give a gradation expression to the metallic luster of such a foil, except for the case where the entire surface was metallic.

The present invention has been made in view of such a problem, and can emit a metallic luster colored in a plurality of colors and easily perform gradation expression and the like, and thin film adhesion with less labor and equipment. The purpose is to provide things.

[0006]

In order to solve the above-mentioned problems, a thin-film adhesive according to the present invention comprises an adhesive layer which is adhered to the surface of an object on one surface of a thin-film which can be attached to the surface of the object. A thin film is formed on the other surface of the thin leaf body, a transparent resin layer is formed on the surface of the thin metal layer, and a plurality of translucent layers are formed on the resin layer. It is characterized in that color inks are printed.

[0007]

In the thin film adhesive according to the present invention, the separator is adhered to one surface of the thin film that can be attached to the surface of the object through the adhesive layer that adheres to the surface of the object, and the other of the thin film is adhered. Since a metal thin film layer is formed on the surface, a transparent resin layer is formed on the surface of the metal thin film layer, and a plurality of transparent inks are printed on the resin layer, The metallic luster appears to be colored in various colors.

Moreover, since a plurality of transparent inks are printed on the resin layer of the metal thin film layer, it is possible to print at one time by silk screen printing, letterpress printing, flexographic printing, etc. Since it is not necessary to prepare a transfer foil or a mold for each color, the labor and equipment can be significantly reduced.

Labels, stickers, sheets,
There are films, papers, etc., but if the thin leaf is a transparent member, the transparent member is first printed with a translucent colored ink, and a foil is placed on this printed surface via an adhesive resin layer. The printed surface and the colored metallic luster can be shown through the transparent member. Labels as transparent members are polyethylene terephthalate, polyolefin, cellophane,
It can be formed of acetate or the like.
