Document Type and Number:
WIPO Patent Application WO/2021/161898
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a thermoplastic resin composition exhibiting high transmittance, low haze, and excellent transparency, scratch resistance, and toughness. A thermoplastic resin composition according to the present invention is characterized by containing: 50-99 mass% of a methacrylic resin (A) composed of 80.0-99.9 mass% of a methacrylic acid ester monomer unit, 0.1-20.0 mass% of a vinyl monomer unit consisting of a vinyl monomer copolymerizable with a methacrylic acid ester monomer excluding maleic acid and maleic anhydride, and 0-4.0 mass% of a maleic acid and/or maleic anhydride monomer unit; and 1-50 mass% of thermoplastic polyurethane (B) having a structural unit derived from polyester polyol and a structural unit derived from isocyanate having an alicyclic ring.
