Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copied image material.

[0002]

2. Description of the Related Art Conventionally, screen printing has been generally carried out as a method for applying a pattern to a base material such as a tile plate, a slate plate or a plastic plate.

However, this method requires labor for color matching particularly when multicolor printing is performed, and it takes time because each color is printed, and when printing a complicated pattern, this method is not suitable. There is a drawback in that this effort and the time required for it are prolonged because of the frequent screen printing.

As a method of remedying these drawbacks, a color copying machine is used to copy a pattern on a transfer paper, and then this is thermally transferred onto a transfer target, and then the transfer paper is peeled off to transfer the transfer target. A pattern is created on an object.

This method has the advantage that it does not require much labor and that a complicated pattern can be formed on an object to be transferred in a short time. On the other hand, the transferred pattern is easily scratched when the object comes into contact with it. Moreover, there is a defect that the pattern is apt to suffer from defects such as fading, peeling, and staining due to light, heat, moisture, contaminants (cigarettes), and the like.

In order to improve the drawbacks of the above method, an attempt was made to form a transparent resin film by applying a transparent resin organic solvent solution on the surface of the pattern formed on the transferred material and drying it. Since the coating property of the solution on the surface was not sufficient, a film excellent in aesthetics and performance could not be obtained.
In addition, this is solved by washing the surface of the pattern formed on the transferred material with an aqueous solution of a surfactant and then applying the above solution, but since the washing and drying steps are involved, the process becomes complicated and troublesome. It has a drawback that it is costly and inferior in productivity.

[0007]

The inventors of the present invention have conducted extensive studies in order to solve the above-mentioned problems, and as a result, the transferred image formed by using a copying machine has a low surface tension. That the transparent resin coating cannot be formed on the surface and that the surface tension is 30 dyn for forming the transparent resin coating.
It was found that all of the above problems can be solved by using a curable transparent resin composition of e / cm or less, and the present invention has been completed.

That is, according to the present invention, a release sheet having (a) a copying resin layer and a copy image layer is transferred onto the surface of a base material so that the surface of the base material and the copy image layer are overlapped with each other, and (b) followed by copying. The resin layer for copying is peeled off from the image layer to obtain a transfer product composed of the substrate and the copy image layer, and (c) a cured transparent resin having a surface tension of 30 dyne / cm or less on the copy image layer of the transfer product. It relates to a copied image obtained by applying and curing the composition.

The copied image of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a release sheet, FIG. 2 is a cross-sectional view of a transfer product in which a copy image layer of a release sheet and a base material are overlaid and transferred,
FIG. 3 is a cross-sectional view of the transfer product obtained by peeling the copying resin layer from the transfer product obtained in FIG. 2, and FIG. 4 is a cured transparent resin composition applied to the transfer product obtained in FIG. 3 and cured. A cross-sectional view of the transcript is shown.

The release sheet is one in which the copy image layer 2 is formed on the surface of the copy resin layer 1 by copying the copy resin layer 1 and, if necessary, a copy sheet having a release layer with a copying machine. Can be used. The copying machine is not particularly limited, and a conventional single-color or multi-color (color) copying machine can be used.
An electrophotographic type in which toner particles are electrostatically fixed is preferable. In copying, the copy image layer 2 is transferred to the base material 3 and inverted in the next step, so that the original image is copied on the back side.

Substrate 3 for transfer using the release sheet
Is a material that does not deteriorate or deform due to heat, and for example, pottery (tile, slate, etc.), wood, glass, metal, plastic, and plates, sheets, and molds made of combinations thereof can be used. Further, the base material 3 may be provided with a primer layer and / or an intermediate coating layer between the base material 3 and the copy image layer 2 and / or the coating film 4. These layers can improve the adhesion between the base material 3 and the copy image layer 2, and by coloring these layers, the color behind the image can be changed to raise the image or blur the image. It is possible to obtain images with different feelings.

Further, the transfer is performed by superposing the surfaces of the copy image layer 2 of the release sheet and the substrate 3 and applying pressure. The pressurization is usually performed in a heated state. Heating is generally about 80-250 ° C, preferably about 150-1.
A range of about 20 to 50 seconds at 70 ° C is preferable. If necessary, the surface of the base material 3 transferred while the base material 3 is warm may be pressed with a cloth or the like to bring the copy image layer 2 into more uniform contact.

The copying resin layer 1 after transfer is peeled from the transfer image layer 2 after cooling. The peeling can be performed directly using a comb or a transfer peeling solution.

The curable transparent resin composition applied to the substrate 3 onto which the copy image layer 2 has been transferred is liquid at room temperature and has a surface tension of 30 dyne / cm or less. Examples of the curable transparent resin composition include acrylic resins, polyester resins, epoxy resins, silicone resins,
Base resin such as fluorinated resin and azo resin, (block)
A resin composition containing a crosslinking agent such as a polyisocyanate compound or a polycarboxylic acid compound, which can be cured at room temperature or by heating, or a polyfunctional oligomer type resin composition which can be cured by irradiating a peroxide catalyst or an active energy ray, etc. Can be used. Further, a coloring agent such as a pigment or a dye may be added to the resin composition to the extent that the copy image layer 2 is not hidden.

The coating of the resin composition can be usually carried out by means of spray coating, flow coating, roll coater coating, electrostatic coating, curtain flow coater coating, screen printing, gravure printing and the like. The coating film thickness (drying) may be appropriately selected according to the required performance and appearance, but is usually about 10 to 200 μm, preferably about 20 to
100 μm is good.

When ultraviolet rays are used for the irradiation of active energy rays, the exposure dose is usually about 10 to 500 mJ / cm ² , preferably about 50 to 300 mJ / cm ² , and when electron rays are used. Is usually about 0.5-20M
A radiant dose of rad, preferably about 2-10 Mrad is good.

Further, the cured coating film formed from the curable transparent resin composition has a surface hardness of JIS K 54.
00) H or more is preferable because it has excellent scratch resistance and abrasion resistance.

The copied image of the present invention can be used, for example, as a building material (wall material, ceiling material, floor material, etc.), an art product, an ornamental product, a display product, or a part of those constituting these.
