Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method of applying adhesive to the surface of a sheet-like base material such as cloth, Japanese paper, or resin film to attach foil. Used to apply foil to Japanese clothing such as kimono, Japanese accessories, wallpaper, etc.

(Prior art and its problems) This type of foil processing involves pasting metal foil or colored foil in its foil state, or by arranging or scattering small pieces or powdered foil. It has been known since ancient times.

In these foil processes, the foil is directly attached to the surface of the flat base material using adhesive, so
There is a disadvantage that the color and luster of the foil appear in a planar manner, resulting in a flat pattern.

In particular, when using metal foil or glossy colored foil, the shine of the foil becomes strong, so if you use foil over a large area, only the foil part will stand out and the pattern will lack depth. Therefore, the range in which the foil can be used is naturally restricted.

These problems could only be solved by weaving the foil pattern with foil thread.

(Conventional Issues) The present invention is a method of applying adhesive to the surface of a sheet-like base material such as cloth, Japanese paper, or resin film to adhere foil, and the present invention is a method of applying foil to the surface of a sheet-like base material such as cloth, Japanese paper, or resin film. The goal is to do so.

(Technical means) The technical means for solving this technical problem are: (a) After the surface of the adhesive has hardened, (b) Forming irregularities on the adhesive layer with a mold material, and (c) Place the foil on the surface and (d) press the foil to adhere it.

The mold materials used in this method include unit mold surfaces in which narrow concave grooves are formed in parallel and assembled so that the grooves of adjacent unit mold surfaces form different angles; It is possible to use one in which the surface is formed of pattern-like unevenness.

In the above method, a colorant or colored filler that is compatible with the foil to be adhered can be mixed into the adhesive.

Alternatively, metal foil pieces and/or glitter powder may be mixed into a transparent adhesive resin, and when the surface of the resin is dry, the above-mentioned mold material may be pressed against the resin and dried to form an uneven pattern.

(Effect of technical means) Since the adhesive whose surface has dried and hardened is not completely hardened on the inside, it is possible to easily form irregularities on the surface of the adhesive layer using a mold material.

When a molding agent is pressed onto the surface of the dried and hardened adhesive layer, the adhesive in the undried inner portion moves, and unevenness is formed in the adhesive layer itself.

Since the surface of the adhesive layer with the unevenness remains sticky, it is possible to place a sheet of foil, small piece of foil, or powdered foil on the surface and apply it using your fingertips, cotton, brush, etc. When pressed, the foil tends to follow the unevenness because the surface of the adhesive layer has unevenness.

At this time, sheet-like foil or small piece-like foil does not have elasticity, so when pressed along the unevenness, minute cracks are generated and form an escape route for air. The foil is adhered along the unevenness without air remaining between the foil and the foil.

In addition, in the case of transfer foil formed on a thin film, since cracks are difficult to form in the foil, it is necessary to gradually attach the foil by heating it while releasing air between the unevenness and the foil from one end side. is desirable.

Because grooves are formed in the mold material, the surface of the foil that is pasted is pasted along the unevenness facing in different directions, so the direction of reflection of the foil changes depending on the viewing angle. become.

If unit mold surfaces with narrow concave grooves formed in parallel are used as a mold material, and mold surfaces are used so that the grooves of adjacent unit mold surfaces form different angles, the angle of the grooves relative to the viewing direction are different from each other, so the direction of light reflection differs for each corner unit mold surface.

In addition, when using a mold surface with pattern-like unevenness, when viewed from the front it will look like a pattern of uneven foil, but by shifting the viewing direction, the angle of the unevenness that makes up the pattern will change, so it is the same as above. A phenomenon occurs.

These molds are manufactured using techniques such as engraving, printing plate making, etc., and it is desirable that the mold surface be formed into a flat shape, an arc shape, or even a roll surface shape.

If a colored material or colored filler that matches the color of the foil is mixed into the adhesive, the color will be visible and hidden on the underside of minute cracks that occur in the foil.

In addition, transparent adhesive resin mixed with metal foil pieces and/or glitter powder such as pearl powder and foil powder is applied to a sheet-like base material, and when the surface is hardened, a mold material similar to the above is pressed. When dried, the angle of the grooves relative to the viewing direction changes, even if no foil is pasted thereon, and the direction in which light is reflected from the foil or powder filled in the resin changes.

(Effects of the present invention) As a result of the reflection direction of the foil differing depending on the viewing angle,
The shine of the foil changes depending on the viewing direction, which has the advantage of creating a varied foil pattern.

In addition, because the unevenness of the foil suppresses the shine of the foil,
It is possible to create a calming foil pattern, and there is an advantage that foil can be used even in large pattern areas.

Placing a matching color on the underside of the cracker has the advantage of allowing the fused color to change depending on the angle from which it is viewed, for example, merging the luster of silver foil into gold leaf, or merging blue into red colored foil. There is.

Incidentally, when a foil piece or glittering powder is mixed into the resin, there is an advantage that the surface glittering process of the sheet-like base material can be easily performed.
