The uncured resin layer was cured by irradiating an electron beam (applied voltage: 175 KeV, 5 Mrad (50 kGy)) to obtain a surface layer (thickness: 5 μm). Thereafter, the composition was heated and cured at 70 ° C. for 24 hours to obtain the decorative material of Example 1. The above-mentioned evaluation was performed about the obtained decorative material. Table 1 shows the evaluation results.

Example 2
In Example 1, instead of the penetration preventing layer, a resin composition for forming a tactile layer (two-component curable resin (base resin: acrylic polyol, curing agent: hexamethylene diisocyanate)), tactile layer (silica particles, average particle size) : 12 μm, 50 parts by mass with respect to 100 parts by mass of the two-component curable resin)), using a pattern plate having a plate depth of 90 μm, so as to have a thickness of 15 μm so as to have a wood grain pattern autumn material portion (light expression portion) The pattern printing was performed so as to be synchronized with the above (1), a tactile layer was formed, and a decorative material was obtained. The above-mentioned evaluation was performed about the obtained decorative material. Table 1 shows the evaluation results.

Example 3
In Example 1, the anti-penetration layer was provided so as to be synchronized with the wood-grained spring material portion, and the resin composition for forming the tactile layer (two-component curable resin (main component: acrylic polyol, curing agent: hexamethylene diisocyanate) ), Silica particles (average particle size: 12 μm, 50 parts by mass with respect to 100 parts by mass of the two-component curable resin)), using a pattern plate having a plate depth of 90 μm, so as to have a grain size of 15 μm. The pattern printing was performed so as to synchronize with the autumn material portion (light expression portion), and a tactile layer was formed to obtain a decorative material. The above-mentioned evaluation was performed about the obtained decorative material. Table 1 shows the evaluation results.

Examples 4 to 6
A cosmetic material was obtained in the same manner as in Example 2, except that the tactile particles in the resin composition for forming a tactile layer were used as the fillers shown in Table 1.

Comparative Example 1
A cosmetic material was obtained in the same manner as in Example 1 except that the penetration preventing layer was not provided.

In Table 1, the touch imparting particles used in the examples are as follows.
Tactile particles a: silica particles (average particle size: 12 μm)
Tactile particles b: aluminum hydroxide particles (average particle size: 4 μm)
・ Tactile feel imparting particles c: acrylic beads (average particle size: 20 μm)
・ Tactile feel imparting particles d: acrylic beads (average particle size: 30 μm)

From the results of Examples 1 to 6, it was confirmed that the decorative material of the present invention had high design properties by multi-step gradation expression. In addition, it was confirmed that the decorative materials of Examples 2 to 6 having the tactile layer had improved tactile sensation and improved design compared to the decorative materials of Example 1 having no tactile layer. Was done.
On the other hand, the decorative material of Comparative Example 1, which did not have the penetration preventing layer and the tactile sensation imparting layer, was not considered to be excellent in both the design property and the tactile sensation.

  The decorative material of the present invention has excellent design properties by multi-step gradation expression by real unevenness only in the printing and coating steps without embossing (shaping) processing. The decorative member is a member for interior or exterior of a building such as a wall, a ceiling, a floor, etc., a window frame, a door, a handrail, a skirting board, a surrounding edge, a fitting such as a mall, or a building member, as well as a kitchen, furniture or light electric appliance. It is suitably used as a decorative surface of a cabinet of a product, OA equipment, or the like, or a member for interior or exterior of a vehicle.
