SYNTHETIC RESIN LAMINATE

摘要

A synthetic resin laminate is excellent in shape stability in high-temperature high-humidity environments and in surface hardness and usable for a transparent substrate material or protection material. A synthetic resin laminate includes a substrate layer containing a polycarbonate (B); and a resin layer laminated on one or both surfaces of the substrate layer, the resin layer containing a resin (A) that contains a (meth)acrylate copolymer (a1) and a polycarbonate (a2); wherein (a1) is a (meth)acrylate copolymer composed of 5 to 80% by mass of an aromatic (meth)acrylate unit (a11) and 20 to 95% by mass of a methyl methacrylate unit (a12); (a2) is a polycarbonate containing a constituent unit represented by formula [1]; and the ratio of (a1) with respect to the resin (A) is 5 to 55% by mass, and the ratio of (a2) with respect to the resin (A) is 95 to 45% by mass.

1. A synthetic resin laminate, which is obtained by laminating
a resin layer containing a resin (A) that contains a (meth)acrylate copolymer (a1) and a polycarbonate (a2) on one surface or both surfaces of a substrate layer containing a polycarbonate (B), wherein the (meth)acrylate copolymer (a1) is a (meth)acrylate copolymer composed of 5 to 80% by mass of an aromatic (meth)acrylate unit (a11) and 20 to 95% by mass of a methyl methacrylate unit (a12), the polycarbonate (a2) is a polycarbonate containing a constituent unit represented by the following formula [1]: (in formula [1], R represents a single bond, an alkylene group having 1 to 6 carbon atoms, an arylene group having 6 to 10 carbon atoms, or a cyclic alkylene group having 3 to 8 carbon atoms), and the ratio of the (meth)acrylate copolymer (a1) with respect to the resin (A) is 5 to 55% by mass, and the ratio of the polycarbonate (a2) with respect to the resin (A) is 95 to 45% by mass.
