Shielding printing layer 1 by irradiation of ionizing radiation
The ionizing radiation-curable resin layer 2 is cured in a portion where 3 is absent,
Further, the ionizing radiation curable resin layer 2 is in an uncured state in a portion where the shield printing layer 13 is present.

(C) Fourth Step As shown in FIG. 2 (c), the ionizing radiation permeable sheet 11 of the transfer sheet 10 is peeled off to remove the ionizing radiation curable resin layer 2.
The uncured portion 21 corresponding to the shield printing layer 13 is removed together with the ionizing radiation transparent 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 base material 3 is cured to obtain the decorative material base material 7 on which the concavo-convex pattern 5 and the printed pattern 6 synchronized with the concavo-convex 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 transparent sheet 11 in the uncured portion of the ionizing radiation curable resin layer 2 and the transfer sheet 10 is peeled off. The adhered portion is removed, and as a result, the concave portion 52 in which a small amount of the uncured ionizing radiation curable resin remains and the convex portion 51 made of the cured ionizing radiation curable resin are formed.

In the present invention, in the fifth step, it is important to form the transparent resin layer 8 on the surface of the convex portion 51 of the printed pattern before performing the wiping described later. The transparent resin layer 8 is provided to protect the printed pattern 6 from polishing described later, and further has a protective function such as prevention of scratches on the surface 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 property and polishing property, and ,
Although the thermosetting resin and the ionizing radiation curable resin are inferior in workability to thermoplastics but are excellent in physical properties after curing, they may be appropriately selected depending on the application of the decorative material. The thickness of this transparent resin layer is preferably 15 to 20 μm.

(D) Sixth step As shown in FIG. 3 (e), wiping is performed on the concave portion 52 of the decorative material base material 7 using the colored ink 9. Wiping is a coating method in which recesses are filled with colored ink and the recesses are colored.The processing method is to apply colored ink (or paint) on the entire surface of the uneven pattern, and then over the uneven pattern with a doctor blade or air. This can be performed by wiping with a knife or a roller 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 convex portion does not have to be completely removed because it is polished later.

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

(D) Seventh Step Finally, the surface of the transparent resin layer is ground with a sander or the like to scrape off the excess colored ink 9, and the surface of the transparent resin layer 8 is ground and smoothed as shown in FIG. 3 (f). The obtained cosmetic material 1 is obtained. As means for polishing the transparent resin layer 8, methods such as wet type, dry type, sandpaper polishing, and buff polishing are used.

Further, in this embodiment, after the transfer sheet 10 is peeled off, ionizing radiation is further irradiated to cure the uncured ionizing radiation curable resin 23 remaining in the recesses 5, but the uncured ionizing radiation curable resin is not yet cured. You may form the recessed part which removed 23 completely. In order to completely remove the uncured ionizing radiation-curable resin, the fact that the remaining uncured portion has high solubility in a solvent is used. It is preferable to adopt a chemical removal method for dissolving and removing the.

Examples of the solvent for dissolving and removing the above 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 and the like, which is selected and used according to the type of the ionizing radiation curable resin used. Dissolving and removing with these solvents can also be carried out only by pouring or dipping, but a more preferable method is to apply a solvent on the formed uneven pattern and then buff it 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 applied and formed on the transparent resin layer 8. The protective coat layer 8 may be formed of the above-mentioned ionizing radiation curable resin, but may be formed of a thermosetting resin. The decorative material having a high-quality paint of the present invention is a door,
It can be used for various purposes such as kitchen doors, surface materials such as furniture, wall materials, etc. Especially, it is optimally used as a woodgrain decorative material by forming woodgrain conduits as uneven patterns and woodgrain patterns as printed patterns. Be done.

The present invention will be described in more detail with reference to specific examples. Example 1 A polyester film having a thickness of 38 μm (polyethylene terephthalate manufactured by Toray) was printed with a white ink (UVH white manufactured by Showa Ink) that shields ultraviolet rays from a wood grain conduit pattern using a gravure plate having a plate depth of 60 μm, and then colored. A wood grain print layer was formed by gravure printing so that the thickness after drying was 3 μm using a pearl ink (Muroboshi Ink: UVTR) to form a transfer sheet.

Separately, a plywood sheet having a thickness of 2.5 mm was prepared, and an enamel-based paint was applied to the surface of the plywood sheet to subject it to a sealing treatment to obtain a base material. Then, 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 on which the wood grain printing was applied was stacked so that its printed surface was in contact with the ultraviolet curable resin layer of the substrate, and five ozoneless ultraviolet lamps having an output of 80 w / cm were installed from the polyester film side of the transfer sheet. After irradiating while passing through the irradiation device at a speed of 20 m / min to cure the ultraviolet curable resin layer, the polyester film of the transfer sheet was peeled off.

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

Further, the uncured UV-curable resin layer remaining on the base material is cured by passing the decorative material base material through the irradiation device, and a two-component curable urethane resin-based transparent paint is used. After forming the transparent resin layer on the convex portion of the decorative material base material, wiping is performed on the transparent resin layer by a roll coater method using a two-component curable urethane resin-based brown coating material to form the concave portion. Filled with paint. After wiping, the surface of the base material of the decorative material was sanded to remove the wiping ink (two-component curing type urethane resin-based brown colored paint) remaining on the surface of the transparent resin layer. It does not reach printing). Thereafter, for the purpose of adjusting the gloss, a protective coating layer having a thickness of about 5 μm was spray-coated on the entire surface of the decorative material using a gloss-adjusting clear paint (urethane type) to obtain a decorative material. The obtained decorative material had a high surface hardness, had a high-grade painting feeling, and had excellent designability without scraping of printed patterns.

Example 2 A printing sheet (thickness: 30 g) having a pearl resin grain pattern on a base material
/ M ² thin paper) was used in Example 1
A cosmetic material was formed in the same manner as in.

Claims (2)

[Claims] 1. A transfer sheet comprising an ionizing radiation permeable sheet provided with a shielding printing layer made of an ionizing radiation shielding ink and a printing layer as a transfer layer, the surface of which is coated with an ionizing radiation curable resin layer. The printing layer of the transfer sheet is superposed on the base material so as to be in contact with the ionizing radiation-curable resin layer, and ionizing radiation is applied from the ionizing radiation transparent sheet side of the transfer sheet to correspond to a portion other than the shielding printing layer. After curing the ionizing radiation-curable resin, peel off the ionizing radiation-transparent sheet and remove the uncured portion of the ionizing radiation-curable resin layer together with the ionizing radiation-transparent sheet so that the printed layer adheres to the ionizing radiation-curable resin. The cured portion formed as a convex portion and the removed portion of the ionizing radiation curable resin as a concave portion,
After curing or removing the uncured ionizing radiation curable resin on the surface of the base material, forming a transparent resin layer on the surface of the convex portion of the base material, and then wiping to fill the concave ink with the surface of the transparent resin layer. A cosmetic material having a high-quality painting feeling, characterized in that it is formed by polishing and removing the excess colored ink on the convex portion. 2. A method for producing a decorative material having a high-grade coating feeling, which comprises sequentially performing the following steps. (A) A printing layer is provided on the surface of an ionizing radiation transparent sheet having a peelable surface, and an ionizing radiation shielding ink is used on either the front or back surface of the ionizing radiation transparent sheet or the surface of the printing layer. A 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 the surface, and a transfer sheet having an uncured ionizing radiation-curable resin layer on the surface of the transfer sheet or the printing layer, A second step of laminating so that an uncured ionizing radiation curable resin layer is formed between the printed layer and the substrate. (C) A third step of irradiating ionizing radiation from the side of the ionizing radiation transparent sheet of the transfer sheet to cure the portion of the surface of the base material other than the portion corresponding to the shield print layer of the transfer sheet of the ionizing radiation curable resin. (D) The ionizing radiation transmissive sheet of the transfer sheet is peeled off, and the uncured portion of the ionizing radiation curable resin layer corresponding to the shield printing layer is removed together with the ionizing radiation transmissive sheet so that the printing layer is an ionizing radiation curable resin. A fourth step of forming a hardened portion in close contact with. (E) A fifth step of curing or removing the uncured ionizing radiation curable resin remaining on the surface of the base material. (F) A sixth step of providing a transparent resin layer on the surface of the convex portion of the base material. (G) A seventh step in which the recesses of the transferred product are wiped with a coloring ink and the surface of the transparent resin layer is further polished to scrape off the excess coloring ink.
