PROBLEM TO BE SOLVED: To provide a flooring hardly influenced by water, the surface of which is hardly scratched or dented even if a load is imposed on a caster etc., and which does not damage design by presenting irregularities of a plywood surface as it is on the surface of a decorative sheet. SOLUTION: In this flooring material, resin-impregnated paper impregnated with a thermosetting resin is thermocompression-bonded in the state of being placed on a thermosetting resin layer which is formed by coating one surface of plywood with the thermosetting resin, so that a composite material can be integrally molded by curing a resin of the thermosetting resin layer while making the resin penetrate the resin-impregnated paper; and a decorative sheet, the surface layer of which is provided with a surface protecting layer composed of an ionizing radiation-curing resin, is stuck on the resin-impregnated paper surface of the composite material via an adhesive layer. The flooring is characterized in that the basis weight of the impregnating base paper of the resin-impregnated paper is 80g/m<SP>2</SP>or more. COPYRIGHT: (C)2008,JPO&INPIT |
