Representative examples of ionizing radiation used in the present invention are ultraviolet rays and electron beams, but other types can also be used. The shielding printing layer 1 is irradiated by ionizing radiation.
In the part without 3, the ionizing radiation-curable resin layer 2 is cured,
In addition, the ionizing radiation-curable resin layer 2 is in an uncured state in a portion where the shielding print layer 13 exists.

(C) Fourth Step As shown in FIG. 2 (c), the ionizing radiation-permeable sheet 11 of the transfer sheet 10 is peeled off and the ionizing radiation-curable resin layer 2 is removed.
The uncured portion 21 corresponding to the shielding print layer 13 is removed together with the ionizing radiation-permeable sheet 11 to form the cured portion 4 in which the printing layer 12 is in close contact with the ionizing radiation-curable resin 22.
Further, the uncured ionizing radiation-curable resin 23 remaining on the surface of the substrate 3 is cured to obtain the decorative material substrate 7 in which the uneven pattern 5 and the printed pattern 6 synchronized with the uneven pattern 5 are formed. When the transfer sheet is peeled off after the irradiation of the ionizing radiation, the uncured ionizing radiation-curable resin 21 adheres to the ionizing radiation-permeable sheet 11 at the uncured portion of the ionizing radiation-curable resin layer 2 and the transfer sheet 10 is peeled off. The adhering portion is removed, and as a result, a concave portion 52 in which a small amount of the uncured ionizing radiation-curable resin remains and a convex portion 51 made of the cured ionizing radiation-curable resin are formed.

The transparent resin layer 8 is provided to protect the printed pattern 6 from polishing described below, and further has a protective function such as preventing the surface from being damaged when used as a decorative material. The transparent resin layer 8 can be formed of a known thermoplastic resin, a thermosetting resin, an ionizing radiation-curable resin, or the like. The thermoplastic resin has good workability such as coating properties and polishing properties, and ,
The thermosetting resin and the ionizing radiation curable resin are inferior in workability to thermoplasticity but have excellent physical properties after curing. Therefore, they may be appropriately selected according to the use of the decorative material. The thickness of the transparent resin layer is preferably formed in a range of 15 to 20 μm.

(E) Sixth Step As shown in FIG. 3 (e), wiping is performed on the concave portion 52 of the decorative material substrate 7 using the coloring ink 9. Wiping is a coating method in which the concave portions are filled with coloring ink and the concave portions are colored. As a processing method, a coloring ink (or paint) is applied to the entire surface of the concave and convex pattern, and then a doctor blade and an air are applied on the concave and convex pattern. It can be performed by wiping with a knife or a roller or the like having a sponge, cloth, or the like as a surface material, and removing the ink on the convex portions. At this time, the ink on the projections does not have to be completely removed because the ink is polished later.

The coloring ink may be selected from known inks, and the binder resin may be an aqueous emulsion composed of acryl, vinyl chloride-vinyl acetate copolymer, or a curing agent such as isocyanate or amine. It is desirable to use two-component curing type polyurethane, polyester, epoxy, melamine, etc. using The coloring pigment may be selected from known pigments such as red iron oxide, graphite, black ink, cyanine blue, and polyazo.

(F) Seventh Step Finally, the surface of the transparent resin layer is polished with a sander or the like to remove excess colored ink 9, and the surface of the transparent resin layer 8 is polished and smoothed as shown in FIG. The obtained decorative material 1 is obtained. As a means for polishing the transparent resin layer 8, a method such as a wet type, a dry type, sand paper polishing, and buff polishing is used.

In this embodiment, after the transfer sheet 10 is peeled off, the uncured ionizing radiation-curable resin 23 remaining in the concave portion 5 is cured by further irradiating ionizing radiation. A concave portion from which 23 has been completely removed may be formed. To completely remove the uncured ionizing radiation-curable resin, use the high solubility of the remaining uncured portion in the solvent, and use an appropriate solvent to remove the uncured ionizing radiation-curable resin. It is preferable to employ a chemical removal method for dissolving and removing the compound.

Solvents for dissolution and removal include esters such as ethyl acetate and n-butyl acetate; ketones such as methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone; ethanol, isopropanol,
There are alcohols such as n-butanol, etc., which are selected and used according to the type of ionizing radiation-curable resin used. Dissolution removal by these solvents can be performed only by pouring or immersion, but a more preferable method is to apply a solvent on the formed uneven pattern and then buff polishing using a brush or a cotton buffing roller. is there.

Further, if necessary, the transparent resin layer 8 is polished, and then a protective coat layer 15 is formed on the transparent resin layer 8 by coating. The protective coat layer 8 can be formed of the above-mentioned ionizing radiation curable resin, but may be formed of a thermosetting resin. The decorative material having a high-grade paint feeling of the present invention is a door,
It can be used for various applications such as kitchen doors, furniture and other surface materials, wall materials, etc., but it is particularly suitable for use as a woodgrain decorative material by forming a woodgrain conduit as an uneven pattern and providing a woodgrain pattern as a printed pattern Can be

Hereinafter, the present invention will be described in more detail with reference to specific examples. Example 1 After printing a wood grain pattern on a 38 μm thick polyester film (manufactured by Toray: polyethylene terephthalate) with a white ink (manufactured by Showa Ink: UVH White) that blocks ultraviolet rays, using a gravure plate having a plate depth of 60 μm, coloring was performed. The transfer sheet was formed by gravure printing using a pearl ink (manufactured by Morohoshi Ink: UVTR) so that the grain print layer had a thickness of 3 μm after drying.

Separately, a plywood having a thickness of 2.5 mm was prepared, and an enamel-based paint was applied to the surface of the plywood and subjected to a sealing treatment to obtain a base material. Next, an ultraviolet-curable coating material was flow-coated on the surface of the base material so as to have a thickness of 100 μm to form an uncured ultraviolet-curable resin layer. Then, the transfer sheet subjected to the grain printing was overlapped so that the printing surface thereof was in contact with the ultraviolet curable resin layer of the base material, and five towers of ozoneless ultraviolet lamps having an output of 80 w / cm were installed from the polyester film side of the transfer sheet. Irradiation was performed while passing through the irradiation device at a speed of 20 m / min to cure the ultraviolet curable resin layer, and then the polyester film of the transfer sheet was peeled off.

By peeling off the polyester film, most of the ultraviolet-curable resin layer becomes uncured in a portion corresponding to the printed pattern printed with white ink, and a part of the layer adheres to the polyester film together with the transfer layer and is removed. In the other portions of the UV-curable resin layer (other than the portion corresponding to the pattern portion printed with white ink), the UV-curable resin layer cured with the grain print layer remains on the base material, A decorative material base was obtained in which the resin layer was removed and formed as a concave portion of the wood grain conduit.

Further, the decorative material base material is passed through the irradiation device to cure the uncured ultraviolet curable resin layer remaining on the base material, and a two-component curable urethane resin-based transparent paint is used. After forming a transparent resin layer on the convex portion of the decorative material base material, wiping with a roll coater method using a two-component curable urethane resin-based brown paint from above the transparent resin layer to form a concave portion on the concave portion. Paint was filled. After wiping, sanding was performed on the surface of the decorative material base material, and the wiping ink (a paint that was colored in a two-component curable urethane resin-based tea system) remaining on the surface of the transparent resin layer was scraped off (the whole transparent resin layer was cut off, but the wood grain was removed). Printing is not reached). Thereafter, for the purpose of gloss control, a protective coating layer was provided to a thickness of about 5 μm by spray coating using a gloss control clear paint (urethane-based) over the entire surface of the decorative material to obtain a decorative material. The obtained decorative material had a high surface hardness and a high-grade paint feeling, and also had an excellent design without shaving of the printed pattern.

Example 2 A printed sheet (30 g thick) of a pearl resin wood-grain pattern was used as a base material.
Example 1 except that a sheet of paper / m ² was used.
A decorative material was formed in the same manner as described above.

The printed pattern is protected from the polishing treatment after wiping while having a deep high-grade paint feeling, so that the printed pattern is not shaved and the design property is not degraded. In addition, the method for producing a cosmetic material having a high-grade coating feeling according to the present invention includes forming a transparent resin layer before wiping,
Since the method has the step of performing the grinding treatment, it has an effect that the decorative material having excellent design properties can be reliably manufactured.

(57) [Claims] An ionizing radiation-curable resin layer is coated on the surface of a transfer sheet provided with a shielding printing layer made of an ionizing radiation shielding ink and a printing layer as a transfer layer on an ionizing radiation transmitting sheet. The printed layer of the transfer sheet is superimposed on the base material so as to be in contact with the ionizing radiation-curable resin layer, and the transfer sheet is irradiated with ionizing radiation from the ionizing radiation-permeable sheet side of the transfer sheet to correspond to portions other than the shielding print layer. After the ionizing radiation-curable resin is cured, the ionizing radiation-curable resin sheet is peeled off, and the uncured portion of the ionizing radiation-curable resin layer is removed together with the ionizing radiation-curable sheet, and the printing layer adheres to the ionizing radiation-curable resin. The cured portion is formed as a convex portion, and the removed portion of the ionizing radiation-curable resin is formed as a concave portion,
After curing or removing the uncured ionizing radiation-curable resin on the surface of the substrate, forming a transparent resin layer on the surface of the convex portion of the substrate, wiping and filling the concave portion with the coloring ink, and then removing the surface of the transparent resin layer. A decorative material having a high-grade paint feeling, characterized by being formed by polishing and removing excess colored ink remaining on the convex portions. 2. A method for producing a decorative material having a high-grade coating feeling, comprising sequentially performing the following steps. (A) A printing layer is provided on the surface of an ionizing radiation-permeable sheet having a releasable surface, and an ionizing radiation shielding ink is used on either the front or back surface of the ionizing radiation-permeable sheet or the surface of the printing layer. First step of preparing a transfer sheet provided with a shielding print layer. (B) a substrate having an uncured ionizing radiation-curable resin layer on the substrate or surface and a transfer sheet having an uncured ionizing radiation-curable resin layer on the surface of the transfer sheet or printing layer, A second step of superimposing an uncured ionizing radiation-curable resin layer between the printed layer and the substrate so as to form an uncured ionizing radiation-curable resin layer. (C) a third step of irradiating the transfer sheet with ionizing radiation from the side of the ionizing radiation-transmissive sheet to cure portions of the transfer sheet of the ionizing radiation-curable resin other than the portion corresponding to the shielding print layer of the transfer sheet; (D) removing the uncured portion corresponding to the shielding printing layer of the ionizing radiation-curable resin layer together with the ionizing radiation-curable sheet by peeling off the ionizing radiation-transmissive sheet of the transfer sheet to form an ionizing radiation-curable resin; A fourth step of forming a hardened portion in close contact with the substrate. (E) a fifth step of curing or removing the uncured ionizing radiation-curable resin remaining on the substrate surface. (F) A sixth step of providing a transparent resin layer on the surface of the convex portion of the base material. (G) Wiping is performed on the concave portion of the transfer product using a coloring ink, and the surface of the transparent resin layer is further polished to leave it on the convex portion of the base material.
Seventh step of scraping off excess coloring ink that.
