上した。Example 1 A PvC paste sol for packing was applied to the back side of a glass fiber nonwoven fabric (basis weight 50 g/m) to a thickness of 1.0 I after drying.
It is applied so that it becomes ll/II1 and heated to gel. On the other hand, PvC paste was also applied to the surface side of the glass fiber nonwoven fabric, and the surface was smoothed and heated to gel at the same time, thereby forming a base material layer. A printed pattern is applied to the surface of this base layer using a transfer printing method, and an ultraviolet curable paint consisting of an acrylic-urethane photocurable resin and a photoinitiator (penzophenone) is applied to the printed layer to a thickness of 0.3 m/m. Spread glass beads (particle size 0.4 m/m) over the entire surface (spraying amount: 60 m/m).
0 g/rrr) The coating material was cured by irradiating with ultraviolet rays to obtain the flooring material of the present invention. This flooring material had a good design, with the printed pattern visible through it, and also had good cigarette resistance. Example 2 A flooring material was obtained in the same manner as in Example 1, except that after bead scattering, a small amount of acrylic/urethane ultraviolet curable paint was applied thereon. In addition to the effects of Example 1, wear resistance was improved.
