Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method in which a concavo-convex pattern is formed on a surface by arranging a plurality of groups of fine line-shaped concavo-convex patterns with the line directions gradually changing. The present invention relates to a method of manufacturing an image forming body in which a concavo-convex pattern forming body is arranged only on a specific portion of a transfer target.

[Prior art of the invention and its problems]

As an image forming body having a pattern with a fine uneven surface, a group of fine line-like uneven patterns is formed on the surface of a sheet-like substrate having gloss such as metallic luster or specular gloss, and the direction of each group is slightly changed. There is an image-forming body (image-forming body having an opal effect) in which a plurality of groups are formed in different shapes. This image-forming body is, for example, an aluminum surface K of wax-laminated aluminum foil paper, with a pattern applied if necessary,
Thereafter, a press plate having various combinations of fine line-like uneven patterns by changing the line direction little by little is pressed against a press plate.

In such an image-forming body, since the line directions of the fine line-like uneven patterns on the surface of the object are different, the direction of reflection of the reflected light on the pattern surface changes variously, and the viewing angle and direction can vary. By varying this, the shading and brightness of each line-shaped uneven pattern group changes dynamically, creating an extremely brilliant effect (opal effect). Furthermore, it is very difficult to manufacture the concavo-convex pattern used in the production of the image-forming body having the opal effect, and it is also difficult to register the pattern with the pattern previously formed on the sheet-like substrate. It is difficult for three parties to easily create a counterfeit product. Therefore, an image-forming body having such a structure may be placed on or in a card base, or may be used as a gift certificate, membership certificate, bankbook, employee ID card, video tape or audio tape cassette, compact disc, record, book, lottery ticket, etc. If it is pasted on a ticket, etc., it can work effectively as a counterfeit prevention measure. However, as mentioned above, this image forming body is made by forming various combinations of fine line-based uneven patterns on the aluminum surface of wax-laminated aluminum foil paper by gradually changing the line directions. Because it is made by pressing a press plate made of aluminum foil, the base material, aluminum foil paper, may warp due to the influence of humidity and temperature. In order to cut the aluminum foil paper into the desired shape and size and paste it onto the object to be adhered to, the aluminum foil paper is cut into the desired shape and size after forming a concavo-convex pattern on the aluminum surface. It is extremely difficult to accurately form a concavo-convex pattern having the above-mentioned configuration that matches the shape of the specific portion only in a specific portion, and the efficiency is extremely low.

[Purpose of the invention]

The present invention has been made in view of the above circumstances,
The uneven pattern of an image forming body having an uneven pattern body formed by molding a plurality of fine line-like uneven patterns arranged in a plurality of sets by slightly changing the line directions on a glossy colored layer. The present invention relates to a method for manufacturing an image forming body that is very simple to operate and that allows images to be formed only on specific portions of a transfer target with good registration.

[Details of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram of an embodiment of the method for manufacturing an image forming body according to the present invention, and FIG. 2 is an explanatory diagram of the structure of the image forming body obtained by the present invention.

The image forming body referred to in this specification refers to a fine line pattern uneven pattern only on a specific part of the transfer target (L), as shown in FIGS. 1 and 2. Group (height difference between concave and convex parts is about 10 to 20μ, pitch width is 60 to 9
A concavo-convex pattern (2, hereinafter referred to as an opal pattern), which is formed by arranging multiple sets of approximately 0μ) with the line directions slightly changed (2, hereinafter referred to as an opal pattern), is formed on a glossy colored layer (3, hereinafter referred to as an opal pattern). (referred to as a pattern forming body). Opal pattern of image forming body (5) having such a structure/opal pattern (2) on forming body (3)
Because the line directions in a group of fine linear concavo-convex patterns formed on a surface with gloss such as metallic luster or specular luster vary, the direction of reflection of reflected light on the pattern surface changes in various ways. When viewed from various angles and directions, the shading and brilliance of each line pattern group changes dynamically, creating an extremely brilliant opal effect.

In manufacturing the image forming body (5), first the support (7)
Ink containing metal powder, aluminum,
A colored layer (8) made of a metal such as tellurium, bismuth, or nickel and having luster such as metallic luster or specular luster, and an adhesive layer (
9) Prepare a transfer sheet arst, which is formed by laminating at least the adhesive layer (9) as the top layer.

In addition to the colored layer (8) and the adhesive layer (9) described above, the transfer sheet has a release layer qυ and a protective layer (121) as shown in Figure 1 (1). Good. Transfer sheet) (101 is (lυ, protection * a'a, colored layer (8
) and an adhesive layer (91) are laminated in this order.

Transfer sheets that can be applied to the present invention are not limited to hot stamp type transfer sheets having such a configuration, but include pressure-sensitive transfer type transfer sheets that have a pressure-sensitive transfer layer that includes at least an adhesive layer made of a pressure-sensitive adhesive and a colored layer. In other words, when pressed using the press plate (17) described later, the transfer layer of only the suppressed portion is transferred to the transferred object side, and the uneven pattern ←e of the press plate αη can be formed into a glossy colored layer. Any configuration is acceptable.

Once the transfer sheet with the above structure is prepared, place this transfer sheet on the transfer target Qs so that the adhesive layer is in contact with it, and then apply the opal pattern (let-press plate αnt- formed on the press section). Transfer sheet (transfer sheet that corresponds only to the part that is heated from the support (7) side of 101 and is heated as necessary and is pressed by the opal pattern (16)) (1 (It is colored layer (8) ) and adhesive layer (
9) is transferred at least to the transfer target α9 side, and the colored layer (
On 81, at least an opal pattern forming body (3) formed by molding an opal pattern is selectively placed. The transferred object α9 in FIG. 1 and FIG. 2 show an image-forming body (5) having an opal pattern-formed body (3) thus obtained. In the illustrated embodiment, the adult body is not buried but is formed in the shape of a protrusion.

〔Effect of the invention〕

The present invention is as described above, and instead of forming an opal pattern on wax-laminated aluminum foil paper (opal paper) and placing it in or on a transfer target, A press in which an opal pattern is formed using a transfer sheet consisting of at least a glossy colored layer and an adhesive layer laminated on one side of a support with the adhesive layer being the uppermost layer. The plate transfers at least the glossy colored layer and adhesive layer of the transfer sheet to the transfer object side with the pattern facing down, and the opal pattern of the press plate is imprinted on the colored layer transferred in Butter 7 Autumn. It becomes possible to arrange the opal pattern-formed body only in a specific part of the transfer body with good registration by a very simple operation.
