た部分が濃色となり鮮明で良好な意匠が得られた。The obtained sheet-like material had a colored resin layer having a thickness of 2.0 mm and excellent in surface smoothness. When a mold with an uneven pattern on this sheet-like material was hot pressed at 200 ° C. for 2 seconds, the concave part reached the deep part of the sheet base material, the surface was smooth and the uneven pattern was extremely excellent in three-dimensional impression. The colored portion became dark and a clear and good design was obtained.

Except that a liquid in which 5 parts by weight of pigment and 5 parts by weight of pigment are mixed and dissolved is used,
A sheet-like material was obtained in the same manner as in Example 1.

られなかった。The softening points of the polyurethane in the sheet base material of the obtained sheet material and the polyurethane of the colored resin layer were both 210 ° C. When a mold was hot-pressed on this sheet-like material under the same conditions as in Example 1, the concave portion did not penetrate into the sheet base material, resulting in an uneven pattern having a poor three-dimensional effect, and a clear design could not be obtained.

A sheet-like material was obtained in the same manner as in Example 1 except that a non-woven fabric was used.
