Description of the Related Art Conventionally, as a matte decorative sheet used for furniture, housing equipment, etc., a vinyl chloride resin sheet as a base material is colored, printed, etc., and then applied with a heated mold roll. It is known to apply matting by mechanical embossing such as pressing. The mold roll has a fine uneven shape formed on the surface by an engraving method, an etching method, a sand blast method or the like, and forms a mat.

Because of the projection, the finger feel is rough and it is hard to say that it is smooth.
Furthermore, matting with a mat material has the disadvantage that the gloss increases as the protrusions of the mat material are rubbed.

ないものとなる。In applying the resin containing the elastic spherical beads in the present invention, the elastic spherical beads are held as a resin layer in order to give a smooth texture to the elastic spherical beads, so that the resin application amount is approximately 15 g / m 2. Although the above is required, when the resin containing the elastic spherical beads is a solvent-based or water-based resin, the solvent or water is dried at a coating amount of 15 g / m 2 or more and then dried to wind up as a decorative sheet. Production is difficult and productivity is reduced. In particular, in the case of a base sheet having low heat resistance such as a vinyl chloride resin film, the base sheet itself is thermally deformed, so that it is difficult to dry with hot air.

It was found that even a base sheet having low heat resistance, such as a vinyl chloride resin film, was not significantly deformed.

Smooth finger feel and texture can be obtained, and the protruding portion has resilience even when rubbed with a finger, and gloss is hardly increased.

The decorative sheet was obtained by irradiating an electron beam of 0 Kv and 3 Mrad. The electron beam-curable resin was 50 parts by weight of “M-8030” manufactured by Toa Gosei Chemical Industry Co., Ltd.
A mixture of 25 parts by weight of the functional monomer, 20 parts by weight of black colored urethane spherical beads having a particle size of 30 to 50 μm, 4 parts by weight of a black pigment, and 1 part by weight of a slip agent was used. The obtained decorative sheet was a black, moist matte, smooth finger feel and texture. The luster of the protruding portion did not increase even when rubbed with a finger.

り、光沢は上がりにくく、傷もつきにくい。As described above, on the surface of the decorative sheet according to the present invention, spherical beads of an elastically deformable material are dispersed,
Since the resin layer is partially covered with the protruding resin layer, a smooth velvet or suede-like finger touch and texture can be obtained. Since the curing of the resin layer is performed by electron beam curing, even if the amount of application is large, the curing is fast and easy, and the production efficiency is high. Further, since the heat does not increase, even a base sheet having low heat resistance such as a vinyl chloride resin film is unlikely to be deformed. The protruding portion is a spherical bead made of an elastically deformable material, and has resilience even when rubbed with a finger, hardly increases gloss, and is hardly scratched.
