Patent ID: 7494713

Claim:
A flooring material which comprises the following synthetic resin A, synthetic resin B, and synthetic resin C and having: a face layer formed from a synthetic resin composition obtained by compounding ingredients comprising 30-60 parts by weight of synthetic resin A, 10-50 parts by weight of synthetic resin B, 10-40 parts by weight of synthetic resin C, the sum of the resins A, B, and C being 100 parts by weight, 1-15 parts by weight of a viscosity improver, and 150-500 parts by weight of a filler; and a groundwork layer formed from a synthetic resin composition obtained by compounding ingredients comprising 0-30 parts by weight of synthetic resin A, 30-60 parts by weight of synthetic resin B, 41-60 parts by weight of synthetic resin C, the sum of the resins A, B, and C being 100 parts by weight, 1-15 parts by weight of a viscosity improver, and 150-500 parts by weight of a filler: Synthetic resin A: α-resin comprising a polyethylene resin and/or an ethylene/α-olefin copolymer resin; Synthetic resin B: a flexible ethylene-based resin comprising one or more members selected from ethylene/vinyl acetate copolymer resins, ethylene/vinyl alcohol copolymer resins, ethylene/acrylic acid copolymer resins, ethylene/methacrylic acid copolymer resins, ethylene/ethyl acrylate copolymer resins, ethylene/methyl methacrylate copolymer resins, ethylene/acrylic ester/maleic anhydride terpolymer resins, and ethylene/acrylic ester/epoxy terpolymer resins; Synthetic resin C: a thermoplastic elastomer comprising one or more members selected from ethylene/vinyl acetate copolymer thermoplastic elastomers, olefin-based thermoplastic elastomers, and styrene-based thermoplastic elastomers.
