Title:
TRANSPARENT RESIN LAMINATE AND TRANSPARENT SUBSTRATE MATERIAL AND TRANSPARENT PROTECTIVE MATERIAL USING THE SAME
Document Type and Number:
Japanese Patent JP2022029793
Kind Code:
A
Abstract:
To provide a resin laminate having excellent thermal moldability at low temperature and having good appearance with suppressed formation of interference fringes.SOLUTION: The above-mentioned problems are solved by a resin laminate having a layer containing a thermoplastic resin (B) at least on one surface of a layer containing a polycarbonate-based resin (A) including a polycarbonate resin as a main component, and a hard coat layer at least on one side surface of the layer containing the thermoplastic resin (B). The thermoplastic resin (B) contains a vinyl copolymer (C) and a styrene copolymer (D). Based on a total content amount of 100 pts.mass of the vinyl copolymer (C) and the styrene copolymer (D), the content of the vinyl copolymer (C) is 20-45 pts.mass and the content of the styrene copolymer (D) is 80-55 pts.mass. The vinyl copolymer (C) is a copolymer containing 60-80 mol% of a (meth)acrylic acid ester monomer unit (c1) represented by the following general formula (1) and 40-20 mol% of an aliphatic vinyl monomer unit (c2) represented by the following general formula (2). The styrene copolymer (D) is a copolymer containing 80-90 mol% of a vinyl aromatic monomer unit (d1) and 10-20 mol% of a cyclic acid anhydride monomer unit (d2).SELECTED DRAWING: None
