[Prior Art] Various methods have conventionally been used to impart a pearly luster to a synthetic resin film, and the majority of these methods use a mixture mainly formed of a pearl pigment and mixed with the film. . In particular, efforts have been made to reproduce the unique color tone of pearls when used for decoration. As one of such methods, there is an example in which a film layer having a different transmittance is used in combination with an adhesive layer, and a product using this has been well-received for exhibiting a luster close to that of a pearl.

[Problem to be Solved by the Invention] However, even with such a product, a pearly feeling has not yet been exerted strongly. Particularly, depending on the type of the adherend using the sheet, the color tone of the base is superimposed due to the light transmitted through the sheet, and the pearl light emitting effect of the sheet itself may be reduced.

[Means for Solving the Problems] The inventor has recognized that the conventional pearl film produces a pearly feeling depending on the angle at which a person views. Because this is due to the directionality of light from the adhesive sheet plane,
It was presumed that the unevenness of the surface would reduce the difference in the pearl feeling depending on the viewing angle. When the sheet was embossed, it was found that the surface was sharpened and the pearl tone was enhanced more than expected. In order to promote the concealing property on the adherend surface, the film was made opaque by kneading a pigment into the film.However, especially when the transmitted light was blocked by interposing a vapor deposition film, the concealing property was further improved. However, it was found that the pearl tone was further enhanced due to the superposition effect of the reflected light from the deposition surface.

In the embossing of the pearl film in the present invention,
Press the synthetic resin film between the male and female molds
A method of heating is used, but it is difficult to hold the unevenness obtained by this method alone in the film, for example, PE
After laminating a plastic film having a relatively high heat distortion temperature such as T in advance, it is desirable to emboss the pearl film to form an embossed film. Therefore, in this case, the film having a higher heat deformation temperature is required to have a higher heat deformation temperature than the heating temperature at the time of embossing.
It is desirable to use an opaque film for promoting the concealing property of the film, but it is advantageous to apply a vapor deposition process to one side of the film in advance so that the concealing property can be further promoted.

The above method uses a film in which a pearl pigment has been kneaded in advance and uses an adhesive on the back surface, but the pearl pigment can be kneaded into either the film or the adhesive, and the effect obtained is not much different. This was easily conceived, and it was found that it was possible by actually testing it, and that the pearly feeling could be further deepened.

The embossed film 1 is obtained by embossing a thermoplastic synthetic resin film, and is a film in which a pearl pigment has been kneaded in advance. The embossed film 1 is preliminarily coated with an adhesive on the entire back surface of the thermoplastic synthetic resin film to form an adhesive layer 2, and is then subjected to embossing after attaching a vapor-deposited or opaque synthetic resin film 3. It is a laminate of the film 1. The heat-deformation temperature of the vapor-deposited or opaque synthetic resin film 3 is relatively high, that is, the pigment is kneaded into a synthetic resin having a heat-deformation temperature higher than the heating temperature at the time of the embossing to make it opaque, or one side is vapor-deposited. It has been processed. Further, an adhesive layer 4 is provided on the back surface to form an adhesive sheet. In addition, a release paper 7 is usually attached to the adhesive layer 4 to protect the adhesive surface until immediately before use, so that a product is obtained.

In the above structure example of the present invention, the adhesive layer 2 is interposed. However, after removing the adhesive layer, the thermoplastic synthetic resin film is vapor-deposited or directly heat-fused to the opaque synthetic resin film 3, and then the thermoplastic synthetic resin film 3 is heated. A method of embossing a synthetic resin film into the embossed film 1 is also widely known, and almost the same adhesive effect can be obtained, and the effect of holding the embossed film can be sufficiently obtained.

The embossed film 5 is obtained by vapor-depositing a transparent thermoplastic synthetic resin film or bonding to the opaque synthetic resin film 3 and then embossing. However, unlike the embossed film 1 shown in FIG. There is no film. On the other hand, unlike the adhesive layer 2, a pearl pigment is kneaded into the adhesive layer 6 and used. Adhesive layer 6
Since the coating fills the concave portion of the embossed film 5 by coating and hardly leaves a void, it is possible to exhibit almost the same effect as the pearl pigment contained in the embossed film.
