Document Type and Number:

WIPO Patent Application WO/2013/172381

Kind Code:

A1

Abstract:

The objective of the present invention is to provide a synthetic resin laminate, which has excellent surface hardness and shape stability in high-temperature high-humidity environments, and which is used for transparent substrate materials and protective materials. The above-mentioned objective can be achieved by 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 base layer that contains a polycarbonate (B), and which is characterized in that: the (meth)acrylate copolymer (a1) is composed of 5-80% by mass of an aromatic (meth)acrylate unit (a11) and 20-95% by mass of a methyl methacrylate unit (a12); the polycarbonate (a2) contains a constituent unit represented by formula [1]; the ratio of the (meth)acrylate copolymer (a1) in the resin (A) is 5-55% by mass; and the ratio of the polycarbonate (a2) in the resin (A) is 95-45% by mass.
