Title:

RESIN LAMINATE AND TRANSPARENT SUBSTRATE MATERIAL INCLUDING THE SAME AS WELL AS TRANSPARENT PROTECTIVE MATERIAL

Document Type and Number:

Japanese Patent JP2021041614

Kind Code:

A

Abstract:

To provide a resin laminate which exhibits excellent warping deformation resistance even when exposed to high temperature and high humidity and has a good appearance.SOLUTION: The above problem can be solved by the resin laminate having a layer containing a thermoplastic resin (B) on at least one surface of a layer containing a polycarbonate resin (A). The thermoplastic resin (B) has a glass transition temperature of 110-130°C and contains a methacrylic resin (C) and a styrene copolymer (D). The content of the methacrylic resin (C) is 30-70 pts.mass and the content of the styrene copolymer (D) is 70-30 pts.mass based on 100 pts.mass of the total content of the methacrylic resin (C) and the styrene copolymer (D). The styrene copolymer (D) is a copolymer consisting only of a vinyl aromatic monomer unit (d1) and a cyclic acid anhydride monomer unit (d2). The content of the vinyl aromatic monomer unit (d1) is 68-84 mass% and the content of the cyclic acid anhydride monomer unit (d2) is 16-32 mass% based on the total content of the vinyl aromatic monomer unit (d1) and the cyclic acid anhydride monomer unit (d2).SELECTED DRAWING: None
