Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer paper for partially cutting out patterns when painting plastic molded objects.

Conventionally, painting on plastic molded objects has been done by transferring wood grain, etc., and spraying has been done by painting, but if you want to remove a partial pattern, you may need to attach paper to the area you want to remove in advance. After pasting the tape, painting and marking using the above method, the paper and tape must be peeled off, which requires labor, and mass production is not possible.
There were problems such as not being able to make the desired pattern.

The present invention has been devised in view of these points, and it is an object of the present invention to provide a transfer paper for pattern cutting, which can stably process a large amount of partial pattern cutting of any pattern.

Hereinafter, the present invention will be described based on embodiments and with reference to the drawings.

FIG. 1 shows a transfer paper for pattern cutting.

The transfer paper is formed by providing a release agent 2 on a heat-resistant film base 1, partially providing a water-soluble resin layer 3, and providing a heat-sensitive adhesive 4 thereon.

This is transferred onto a transfer object 5 by heating with a heat roller, thereby producing a transfer object shown in FIG. 2 partially provided with a water-soluble resin 3.

In order to partially apply a water-soluble resin to the transfer target, in addition to the above configuration, a layer 3 of water-soluble resin is provided on the entire surface using transfer paper, a heat-sensitive adhesive 4 is provided partially, and hot roll transfer is performed. , transfer the water-soluble resin layer and release agent layer 1 only to the heat-sensitive adhesive 4 portion, or apply the water-soluble resin layer 3 to the entire surface using transfer paper, and then apply the heat-sensitive adhesive layer 4 to the entire surface. The layer 2 of the release agent, the layer 3 of the water-soluble resin, and the layer 4 of the heat-sensitive adhesive are transferred in a pattern to the object to be transferred using a heating plate having a convex part in the shape of a pattern. be able to.

Next, a pattern layer 6 is provided thereon by vapor deposition, by transferring the pattern onto the entire surface with a transfer paper, or by spray painting, as shown in the third figure.

That is, a water-soluble resin is provided in the shape of a pattern on the transfer target 5, and the other parts are vapor-deposited, the pattern, and the paint are closely attached to the transfer target in a state that does not contain the water-soluble resin.

By dissolving and removing the water-soluble resin with water from above the state shown in Fig. 3, and also removing the pattern on top of it, the patterned pattern that is the object of the present invention is obtained as shown in Fig. 4. You can make things that you want.

In the above, the film base material 1 having heat resistance is suitable for use in paper that has been subjected to release processing, polyester film, etc., and is preferably one that does not deform due to heat.

The release agent layer 2 is prepared by dissolving the heat-resistant film base 1 and a release agent-containing resin, such as a rubber resin such as cyclized rubber or an acrylic resin, in an organic solvent, and then applying gravure coating, roll coating, etc. It can be provided by silk screen coating or the like.

In addition, water-soluble resins specifically include polyvinyl alcohol, maleic acid resins, and cellulose resins such as methylcellulose and hydroxycellulose.From the viewpoint of drying, those that are soluble in organic solvents are used, and they can be made into solutions. Print by gravure printing method.

In the present invention, since the transfer paper contains the resin layer, it is possible to remove the pattern using water.

Further, the heat-sensitive adhesive described above is appropriately selected and used depending on the object to be transferred.

For example, for polypropylene, polystyrene, and ABs, chlorinated polyethylene, acrylic, or rubber materials are used.

The object to be transferred using the transfer paper for pattern cutting of this invention is:
It is preferable to use a transparent plate, a molded body, or a milky white molded body that allows light to pass through the cutout, and acrylic resin, vinyl chloride resin, etc. are suitable.

- As is clear from the above explanation, any pattern can be easily cut out using the transfer paper for pattern cutting of the present invention.
