Abstract

PURPOSE:To obtain a picture forming body which is enriched in color expression and excellent in design properties in addition to security properties, and is at low cost and excellent in productivity in comparison with a hologram card by successively laminating at least a vapor deposition layer, a printing layer and a protective layer on the base body of a card and pressurizing these layers with a pressing plate having an uneven pattern which is formed by arranging a fine multilinear uneven pattern group at a plurality of sets while gradually changing the direction of the multi-lines and heating the layers. CONSTITUTION:A releasing protective layer 2 (acrylic resin layer) is provided on a polyethylene terephthalate sheet 1. A vapor deposition anchor layer 3 is applied to the layer. A color printing layer is provided by printing and aluminum is vapor-deposited thereon. An adhesive layer is provided on the uppermost layer. The vapor deposition anchor layer 3 may be positioned on the printing layer 4 provided on the releasing protective layer 2. According to circumferences, the layer 3 may be omitted. the transfer foils 1-6 are brought into contact with the base body 7 of a card via an adhesive layer and pressurized by a pressing plate 8 described hereunder and heated. Thereby the part of the pressing plate 8 is transferred on the base body of the card. The pressing plate 8 has the uneven pattern which is formed by arranging a fine multilinear uneven pattern group at a plurality of sets while gradually changing the direction of the multi-lines.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method in which a concavo-convex pattern is formed on a surface by arranging a plurality of sets of fine line-like concavo-convex patterns with the line directions gradually changing. The present invention relates to an image-shaped precept, in which a patterned precept is arranged on a transfer object, and a method for manufacturing the same.

[Prior art]

As an image forming body having a pattern with a fine unevenness on its surface, a plurality of groups of fine linear unevenness patterns are formed on the surface of a sheet-like substrate having metallic luster by changing the lines slightly for each pixel. There is a certain image-forming body (an image-forming body with an opal effect). This image-forming body is disclosed in, for example, Japanese Patent Laid-Open No. 62-227700, in which a glossy colored layer and an adhesive layer are placed on one side of a support so that the adhesive layer is the uppermost layer. After arranging the transfer sheet formed by laminating at least the adhesive layer so that the adhesive layer is in contact with the adhesive layer, a press plate having an image forming body having an opal effect is pressed from the support side with heating if necessary, and the transfer sheet The portions of the colored layer and the adhesive layer that are pressed by the uneven pattern are transferred onto the transfer object, and a plurality of groups of fine line-shaped uneven patterns are arranged by changing the line direction little by little. There is an image-forming body characterized in that a concave-convex pattern obtained by forming a concavo-convex pattern of the above coloring layer on the uppermost colored layer is provided only on a specific portion of the transfer object. Such an image forming body is
Since the line directions in the group of line-like uneven patterns on the surface are different, the direction of reflection of the reflected light on the surface changes variously, and when the viewing angle and direction are changed variously, each line-like uneven pattern The paleness and brightness of the group changes dynamically,
Creates an extremely brilliant effect (opal effect). The embossed patterns used in the production of image-shaped precepts with this oval effect are extremely difficult to manufacture, making it difficult for a third party to easily forge them. However, the above-mentioned conventional technology only has a colored layer with luster, and the original hue only has a metallic shine due to the opal effect.

(Problems to be Solved by the Invention) As described above, the present invention attempts to solve the problem that conventional opal only creates an opal effect based on the hue of a lustrous material and lacks color expression. . In addition, in order to express color, conventionally a hologram image was formed which was expensive to produce, but it is an object of the present invention to obtain an inexpensive and excellent effect of color expression using the method of the present invention. [Means for Solving the Problems] At least a vapor deposited layer, a printed layer, The present invention provides an image-forming body characterized by sequentially laminating protective layers, and provides a method for manufacturing the image-forming body as described below. A removable protective layer is applied to one side of the support onto the transfer target.
Printing layer. A transfer sheet made by laminating a vapor deposition layer and an adhesive layer such that the adhesive layer is at least the uppermost layer is arranged so that the adhesive layers are in contact with each other, and then a group of fine line-shaped uneven patterns are formed on the lines. A press plate on which a plurality of patterns of protrusions and recesses arranged in a plurality of sets with slightly different directions is formed is pressed from the support side with heating if necessary, and the releasable protective layer and printing layer of the transfer sheet are pressed. The portions of the vapor deposited layer and the adhesive layer that are pressed by the uneven pattern are transferred onto the transfer body, and a plurality of groups of fine line-shaped uneven patterns are arranged by changing the line direction little by little. 1. A method for producing an image-shaped precept, which comprises providing an uneven pattern body obtained by forming an uneven pattern on a releasable protective layer, a printing layer, a storage layer, and an adhesive layer on the transfer target.

[Effect]

The image forming body of the present invention can provide color expression that cannot be obtained with conventional image forming bodies, and can enhance security as well as decorativeness and add value. In addition, since the printing layer is embedded under the protective layer together with the vapor deposited layer, it becomes resistant to peeling and impact w1 (rubbing I!!) [Example] Examples of the present invention will be described below with reference to the drawings. I will explain it in detail. 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) 1, and a vapor-deposited anchor layer 3 is provided.
A color printing layer is formed by printing, aluminum is vapor-deposited on top of this, and an adhesive layer is provided as the top layer. The vapor-deposited anchor layer 3 may be located on the removable protective layer 2 and the printed layer 4, or may be omitted depending on the case. FIG. 2 is a partial sectional view of the image forming body of the present invention. FIG. 3 is a schematic explanatory diagram of how the transfer foil shown in FIG. 1 is transferred to a card base. Adhesive layer 6 of transfer foils 1 to 6 is applied to card base 7
is brought into contact with the card base, and heated under pressure with a press plate 8, which has formed an impressive uneven pattern by arranging a plurality of groups of fine line-shaped uneven patterns by changing the direction of the lines little by little. Transfer the part of plate 8 to the card base. The image-shaped precepts manufactured as described above have richer color expressions than conventional image-type precepts, and the printed layer is embedded under the protective layer together with the vapor-deposited layer. ,
It has the advantage of being resistant to peeling and impact (19! rub). [Effects of the Invention] In addition to the conventional security properties, the image forming body according to the present invention has rich color expression and excellent design, and has excellent productivity effects at lower cost than hologram cards. ．． Furthermore, since the printing layer and the smoke coating layer are embedded under the protective layer, the printed image has the effect of being resistant to peeling and impact (friction).
