Next, as shown in FIG. 3 (C), the decorative material 20 having a three-dimensional effect is obtained by laminating it on the substrate 6 having the adhesive 7 applied on its surface.

The base sheet 2 used in the present invention includes base sheets used for ordinary decorative boards, for example, paper such as thin paper, bleached kraft paper, titanium paper, linter paper, paper board, gypsum board paper. Paper-based substrates such as, polyethylene film, polypropylene film, polyvinyl chloride film, plastic film consisting of polyester film or the like, or metal foil such as copper, iron or aluminum, and the like, or they may be used alone or Lamination films or the like that are appropriately laminated can be used, and as the substrate 6, wood veneer such as wood veneer, wood plywood, particle board, MDF (medium density fiberboard), gypsum board, gypsum board such as gypsum slag board, etc. , Calcium silicate board, asbestos slate board, lightweight foam concrete board or pulp cement board, asbestos cement board, wood chips Instrument panel, fiber cement board or an iron plate such as a glass fiber-reinforced concrete plates, galvanized steel, poly vinyl chloride sol coating steel, aluminum plate, a metal plate such as copper plate and the like. As the base material of the present invention, the base sheet 2 and the substrate 6 may be used individually, or the base sheet 2 and the substrate 6 may be laminated and the base sheet 2 may be used as the front surface side. Is also good.

When a paper-based base material is used as the base material sheet 2, a thickness of 23 to 65 g / m ² is suitable, and a primer 3 is applied to strengthen the paper interval. Is preferred. The primer resin used is urethane resin, acrylic resin, urea resin,
Melamine resin or the like is applied by a known gravure printing method. Further, when the substrate 6 is used alone as a base material, it is preferable to apply an undercoat layer, that is, a primer 3 in order to prevent inhalation of ink, paint, etc. in a later step and to reinforce the surface of the base material. Although it depends on the type of substrate used at this time, a suitable coating amount is 30 to 60 g / m ² ,
Examples of the resin used include urethane resin and acrylic resin, which are usually applied by the roll coating method.

The ink 5 containing a liquid repellent which forms an ink layer having a desired uneven pattern is a known thermoplastic resin,

As the coating method, known coating means such as a gravure printing method, a roll coating method and a reverse roll coating method can be used. 1-100μ as coating thickness
m is preferable, and when the coating amount is small, it becomes difficult to form coating unevenness or the liquid-repellent portion is formed as a concave portion. When the coating amount is too large, the ink of the liquid-repellent portion is repelled and the concave portion is sufficiently formed. Is not formed, and the ink portion is formed thicker than necessary, resulting in high cost.

As the pigment added to the liquid repellent ink, a commonly used organic or inorganic pigment and bright pigment can be used. For example, typical pigments include silica, extender pigments, polyazo pigments, isoindolinone pigments, perylene pigments, carbon black and the like. Then, in order to further develop a three-dimensional effect, it is preferable to use a bright pigment.

Further, as the printing layer, the solid printing layer and the constitution in which the pattern printing layer is provided on the solid printing layer have been described. In the latter case, for example, the surface pattern of stone, cloth, natural leather, etc. , An abstract pattern or the like may be expressed. However, in the case of using a liquid-repellent ink to which a bright pigment is added, the addition amount of the bright pigment mixed with the ink containing the liquid-repellent agent is preferably 5 to 20% by weight. . That is, if the pigment addition amount is too large, the pattern printing layer is hidden, and if the pigment addition amount is too small, the appearance of a three-dimensional effect is insufficient and the design is inferior. The printed layer may be provided on the surface of the above-mentioned base sheet and the surface of the base sheet bonded to the substrate, or may be provided directly on the surface of the substrate.

Next, as shown in FIG. 4 (a), the entire surface of the decorative material 20 is coated with an ionizing radiation curable resin for forming a transparent or semi-transparent surface protective layer 8, and further an ionizing radiation transparent sheet. 9 are superposed and the ionizing radiation 11 is irradiated from the ionizing radiation transparent sheet 9 side to cure the ionizing radiation curable resin on the surface of the decorative material 20 to form the transparent or semitransparent surface protective layer 8. Next, as shown in FIG. 4 (b), the ionizing radiation transparent sheet 9 is peeled off, and an ionizing radiation curable resin layer having a smooth surface and an uneven pattern inside is surfaced as shown in FIG. 4 (c). The decorative material 30 serving as the protective layer 8 is obtained.
