Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention has an uneven pattern formed by arranging a plurality of fine line-shaped uneven patterns in which a plurality of sets are arranged by gradually changing the line direction. The present invention relates to an image forming body in which a pattern forming body is arranged on a transfer target and a method for manufacturing the image forming body.

[Prior art]

As an image forming body having a pattern with a fine uneven surface, a group of fine parallel line uneven patterns is formed on the surface of a sheet substrate having a metallic luster by changing the line for each pixel little by little. There is an image forming body (image forming body having an opal effect). This image-forming body is disclosed, for example, in JP-A-62-227700, in which a colored layer having a gloss and an adhesive layer are provided on one surface of a support on the transferred material so that the adhesive layer is the uppermost layer. After arranging at least a transfer sheet formed by stacking so that the adhesive layers are in contact with each other, a press plate having an image forming body having an opal effect is pressed from the side of the support while heating, if necessary, A portion of the colored layer and the adhesive layer, which is pressed by the concavo-convex pattern, is transferred onto the transfer target body, and a plurality of fine line-shaped concavo-convex pattern groups are arranged by gradually changing the parallel line direction. There is an image forming body characterized in that a concavo-convex pattern obtained by imprinting a concavo-convex pattern on the colored layer as the uppermost layer is provided only on a specific portion of the transfer target. In such an image forming body, since the line directions in the line-shaped uneven pattern group on the surface are different, the reflection direction of the reflected light on the surface changes variously, and the viewing angle and direction also change variously. When you do so, the shade and brilliance of each line-shaped uneven pattern group dynamically changes, producing an extremely splendid effect (opal effect). In the image forming body having the opal effect, it is very difficult to manufacture the emboss pattern used at the time of manufacture, and it is difficult for a third party to easily forge it.

However, in the above-described conventional technique, only the colored layer having gloss is used, and the original hue only shines due to the opal effect.

Further, even when an attempt is made to directly print on such an image forming body, it is difficult to form a good printed image because the surface is made of metal such as aluminum and easily repels the printing ink. Further, even if a printed image was formed, it was easy to peel off due to impact (friction) during handling.

[Problems to be Solved by the Invention]

As described above, the conventional opal is intended to solve the problem that the opal effect is produced only on the basis of the hue of the material having gloss, and the color expression is poor. Further, in order to perform color expression, a hologram image which has a high production cost has been conventionally formed, but another object is to obtain an excellent effect of color expression at low cost by using the method of the present invention. Furthermore, it is another object of the present invention to produce an excellent printed image using the method of the present invention and to produce an image-forming body that is less likely to peel due to friction during handling.

[Means for Solving the Problems]

The present invention provides a peelable protective layer on one surface of a support, a partial printed layer on the peelable protective layer, a vapor deposition layer on the peelable protective layer and the printed layer, and an adhesive on the vapor deposited layer. A transfer sheet formed by stacking at least layers is arranged on the transfer object so that the adhesive layer is in contact, and then a plurality of fine line-shaped uneven pattern groups are arranged in a plurality of lines by gradually changing the line direction. The press plate on which the concavo-convex pattern is formed is pressed from the side of the support to transfer the peelable protective layer, the printing layer, the vapor deposition layer, and the adhesive layer of the transfer sheet onto the transfer target, and the transfer target. The method for producing an image-forming body is characterized in that a pattern-forming body is provided by imprinting on the peelable protective layer, the printing layer, the vapor deposition layer, and the adhesive layer.

[Action]

The image forming body of the present invention can obtain a color expression that cannot be obtained by the conventional image forming body, and can enhance the decorativeness as well as the security and add value. Further, since the print layer is embedded under the protective layer together with the vapor deposition layer, it is resistant to peeling and impact (friction). Furthermore, since the printing layer is provided on the peeling protection layer, the printing ink is not repelled.

〔Example〕

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a sectional view of a transfer foil used in the present invention. A peelable protective layer 2 (acrylic resin layer) is provided on a polyethylene terephthalate sheet (25 μm), a vapor deposition anchor layer 3 is applied, a color print layer is provided by printing, aluminum is vapor deposited on the color print layer, and an adhesive layer is provided on the uppermost layer. Is provided. The vapor deposition anchor layer 3 may be located on the peelable protective layer 2 provided with the printing layer 4, or may be omitted in some cases.

FIG. 2 is a partial cross-sectional view of the image forming body of the present invention.

FIG. 3 is a schematic explanatory view of transferring the transfer foil of FIG. 1 to a card substrate. Transfer foils 1 to 6 are attached to the card base 7 to form an adhesive layer 6
Is contacted with the card base, and a press plate 8 on which a concavo-convex pattern formed by arranging a plurality of fine line-shaped concavo-convex pattern groups is arranged by gradually changing the parallel line direction is heated under pressure, The portion 8 is transferred to the card substrate.

The image-forming body produced as described above is rich in color expression as compared with the conventional image-forming body, and since the printing layer is embedded under the protective layer together with the vapor deposition layer,
It has a strong advantage in peeling and impact (friction).

Further, since the printing layer is provided on the peeling protection layer, there is an effect that a good printed image can be formed without repelling the printing ink.

〔The invention's effect〕

In addition to the conventional security, the image forming body according to the present invention is rich in color expression and excellent in designability, and has an effect of lower cost and higher productivity as compared with a hologram card.

Furthermore, since the print layer is embedded under the protective layer together with the vapor deposition layer, there is an effect that the print image is resistant to peeling and impact (friction).
