A material that generates radicals when irradiated with ultraviolet rays can also be used.

The transfer layer 3 may be formed as a uniform layer or may be provided in a partial pattern.

In addition, the transfer layer 3 is used as a layer with excellent durability by finally curing one of the above two resins, and the curing time is not particularly limited, but the transfer layer 3 is thermally cured. In the case of a transfer sheet formed of a synthetic resin, it is preferable to heat and cure the transfer sheet before transfer.

The ionizing radiation shielding pattern 4 serves as a mask pattern for shielding ionizing radiation when ionizing radiation is irradiated from the upper surface side of the transfer sheet, partially curing and raising the ionizing radiation curable resin layer described below. It is something. In this sense, the position where the ionizing radiation shielding pattern 4 is provided is either the upper surface or the lower surface of the ionizing radiation transparent sheet 2 or the lower surface of the transfer layer 3 in FIG.

When the ionizing radiation is ultraviolet rays, the material forming the shielding pattern 4 may be a substance that reflects and shields ultraviolet rays, such as a filler such as titanium oxide, potassium sulfate, or calcium carbonate, or a material with a particle size of 0°.

When the ionizing radiation is an electron beam, examples include the above-mentioned inks and inks containing other pigment-based inks. The ionizing radiation shielding pattern 4 can be formed using these inks by a normal printing method.

Next, a method for transferring an uneven pattern using a transfer sheet having the above structure will be described in detail.

First, as shown in FIG. 2, the above-mentioned transfer sheet 1 is placed on a transfer base material 6 for forming an uneven pattern, which is coated with a separately prepared ionizing radiation curable resin N5. The transfer layer 3 and the pattern 4 are brought into contact with the ionizing radiation-curable resin layer 5, and are brought into close contact with each other (FIG. 3). The ionizing radiation curable resin layer 5 may be provided in advance only on the transferred substrate 6 side as described above, or may be coated and provided on the transfer sheet l side (not shown in the drawings). 6 may be coated and provided.

The transfer base material 6 may be of any material, such as ■temporary or molded products of metal such as stainless steel, steel, aluminum, or copper, ■glass, marble, ceramics, etc.
Gypsum board, asbestos cement board, calcium silicate board, GR
Inorganic boards or molded products such as C (glass fiber reinforced cement), ■Organic polymer boards or molded products such as polyester, melamine, polyvinyl chloride, diallyl phthalate, or sheets or films thereof, ■Wood, plywood, particle board Examples include wooden boards or molded products such as.

These transfer target substrates 6 may be subjected to surface treatment such as sealing treatment or primer treatment, treatment for improving adhesion, and the like.

The ionizing radiation curable resin layer 5 is mainly composed of polymers, oligomers, hexamers, etc. that have radically polymerizable double bonds in their structure, and contains a photopolymerization initiator, a sensitizer, and other non-reactive substances as necessary. Polymers, organic solvents, waxes, and other additives are readily available in various grades on the market and can be used in the present invention. The ionizing radiation curable resin layer 5 can be formed by a known method such as gravure coating, roll coating, flow coating, or spray coating. The thickness of resin M5 is 3 μm to 1
m, particularly preferably 30 to 200 μm.

After the transfer sheet 1 and the substrate 6 to be transferred are overlapped with the ionizing radiation-curable resin layer 5 in between and brought into close contact with each other, ionizing radiation 7 is applied from the side of the ionizing radiation-transparent sheet 2, which is the base material of the transfer sheet. irradiate (Figure 3). Typical ionizing radiations 7 are ultraviolet rays and electron beams, but other radiations can also be used.

By irradiation with the ionizing radiation 7, the ionizing radiation curable resin layer 5 is cured in the areas without the ionizing radiation shielding pattern 4, and the transferred substrate 6, the resin portion of the cured electron radiation curable resin layer 5, and the transfer The three layers of layer 3 (if this transfer layer is made of an ionizing radiation-curable resin, are cured at the same time) are cured and integrated, while the portion with the ionizing radiation-shielding pattern 4 In this case, the ionizing radiation curable resin layer 5 is left uncured.

When the ionizing radiation transparent sheet 2 is peeled off after irradiation with the ionizing radiation 7, the above-mentioned cured and integrated portion is transferred and remains on the transfer target substrate 6 side, and the uncured portion of the ionizing radiation curable resin layer 5 remains. , the uncured ionizing radiation-curable resin (together with the shielding pattern and transfer layer corresponding to the uncured portion) attached to the TL ionizing radiation-transparent sheet is removed when the sheet 2 is peeled off, and the result is , a recess 8 in which a small amount of uncured ionizing radiation curable resin 5a remains;
Cured portion (convex portion) made of cured ionizing radiation curable resin
9 are formed, and thus a transferred object 10 having the uneven pattern transferred thereto is obtained.

Regarding the curing time of the transfer layer 3 in the present invention, when the transfer layer 3 is formed of a thermosetting resin, it is preferable to heat-cure it before transfer, and when the transfer layer 3 is formed of an ionizing radiation-curable resin. In this case, at the time of transfer, the ionizing radiation curable resin layer 5
Although it is preferable to cure simultaneously with the curing by the ionizing radiation 7, the timing is not particularly limited. In addition to the above-mentioned curing time, for example, if the transfer layer is made of thermoplastic resin, it may be semi-cured before transfer and finally heat-cured during transfer, or it may be heat-cured all at once during transfer. Alternatively, when the transfer layer is formed of an ionizing radiation-curable resin, it may be cured by ionizing radiation before transfer, that is, in the state of a transfer sheet.

In the method of the present invention, after the sheet 2 is peeled off, the uncured ionizing radiation curable resin 5a remaining in the recesses 8 may be further irradiated with ionizing radiation to harden the uncured ionizing radiation curable resin 5a remaining in the recesses 8. The curable resin 5a may be removed. There are various physical removal methods and chemical removal methods to remove the uncured ionizing radiation curable resin remaining in the recess 8.
It is preferable to employ a chemical removal method in which the uncured ionizing radiation-curable resin is dissolved and removed by using an appropriate solvent, taking advantage of the high solubility of the remaining uncured portion in organic solvents. Solvents for dissolving and removing include esters such as ethyl acetate and n-butyl acetate, ketones such as methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone, and alcohols such as ethanol, isopropanol and n-butanol. Select and use according to the type of ionizing radiation-curable resin used. Removal by dissolving with these solvents can be done by simply pouring water or dipping, but a more preferable method is to apply the solvent to the formed uneven surface and then buff it using a brush or cotton puffing roller. There is a way.

In the present invention, when the uncured ionizing radiation curable resin remaining in the recesses is left after being cured without being removed as described above, the uncured ionizing radiation curable resin adheres to the ionizing radiation transparent sheet and is removed. Since the amount of the recess is not always constant, it is possible to form a recess with a varying depth.Especially when the transfer layer is colored or the ionizing radiation-curable resin itself is transparently colored, the depth of the recess may vary. This method has the advantage that it is possible to form a color shading pattern that changes in accordance with the uneven pattern and is completely in sync with the uneven pattern.

Hereinafter, the present invention will be explained in more detail by giving specific examples.

Example 1 A polyester film (manufactured by Toshi ■) with a thickness of 38 μm was used as a base sheet, and a composition for forming an alternating layer having the following composition was applied to the surface of the base sheet using a gravure printing method so that the thickness after drying was 2 μm. , dry to form a colored solid layer, and then print a shielding layer forming composition having the following composition using a gravure plate with a plate depth of 80 μm to form a white shielding pattern layer to create a transfer sheet. did.

Next, the above transfer sheet is superimposed on the calcium silicate plate surface coated with the ultraviolet curable paint so that the surface on the light-shielding pattern layer side is in contact with the surface, and output 8 is applied from the base sheet side of the transfer sheet 1-.
Irradiation was performed while passing at a speed of 20 m/min through an irradiation device equipped with five ozone-less ultraviolet lamps of 0 W 7 cm, and after the irradiation, the base sheet was peeled off. After peeling off the sheet,
Further UV rays were irradiated under the same conditions as above to cure the uncured UV curable paint partially remaining in the recesses.

When the base sheet is peeled off, the UV-curable paint corresponding to the area without the shielding pattern layer provided on the sheet is cured, forming a convex portion of the UV-curable paint, and the colored portion at the same position is cured. The vector layer is also cured by ultraviolet irradiation and transferred onto the convex portion, and on the other hand, in the area corresponding to the shielding pattern layer, a part of the uncured ultraviolet curable paint is transferred to the base material sheet of the transfer sheet. It adhered and was removed when the sheet was peeled off, forming a recess.

The resulting uneven pattern had a sharp pattern and a beautiful appearance due to the presence of the coloring layer.

Furthermore, the uneven pattern had excellent surface properties because the surface was covered with a colored solid layer formed by curing of the ionizing radiation having the above-described structure.

Example 2 A transfer sheet was produced in the same manner as in Example 1, except that a composition having the following composition was used as the composition for forming the transfer layer. This transfer sheet was heat-treated to harden the resin of the transfer layer.

Note that the ultraviolet curable paint was flow coated on the calcium silicate plate side.

The resulting concavo-convex pattern had a sharp pattern, and had excellent surface properties because a transfer layer made of a cured thermosetting resin was transferred onto the convex portions of the convex pattern.

〔Effect of the invention〕

As explained above, according to the method of the present invention, a transfer sheet having a transfer substrate for forming an uneven pattern, an ionizing radiation shielding pattern, and a transfer layer consisting of the resin composition as described above is coated with an ionizing radiation curable resin layer. The ionizing radiation-transparent sheet of the transfer sheet is then peeled off and the uncured ionizing radiation-curable resin adheres to the transparent sheet and removed to form a recess; On the other hand, a method was adopted in which convex portions were formed from a cured ionizing radiation-curable resin layer and a transfer layer transferred onto the layer, and an uneven pattern consisting of the concave portions and convex portions was transferred to the transfer substrate. As a result, a sharp and durable uneven pattern can be easily formed.

Further, according to the present invention, by using the transfer sheet, the surface of the convex portion of the concavo-convex pattern is always coated with a thermosetting resin or an ionizing radiation-curable resin that is solid at room temperature and thermoplastic in an uncured state. Since the formed (cured) transfer layer is transferred, there is no need to perform the conventional surface treatment (such as top coat) after forming the uneven pattern, and it has excellent scratch resistance, abrasion resistance, solvent resistance, and resistance. A concavo-convex pattern with excellent surface properties such as drug resistance and weather resistance can be easily formed at any time.
