A thermoplastic resin laminate is a transparent substrate material or protective material which is excellent in transparency, birefringence, and pattern-formability. The laminate is a synthetic resin laminate formed of a methacrylic resin layer, and a vinyl copolymer resin layer laminated on one or both sides of the methacrylic resin layer. The vinyl copolymer resin contains a (meth)acrylate structural unit and an aliphatic vinyl structural unit represented by specific formulas. The ratio of the sum of the (meth)acrylate structural units and the aliphatic vinyl structural units is 90 to 100 mol % with respect to all the structural units that form the resin. The ratio by mole of the (meth)acrylate structural unit to the aliphatic vinyl structural unit is 65:35 to 85:15. The methacrylic resin contains a structural unit having no benzene ring in an amount of 90 mol % or more with respect to all the structural units.
A thermoplastic resin laminate formed of a methacrylic resin (B) layer, and a vinyl copolymer resin (A) layer laminated on one side or both sides of the methacrylic resin (B) layer, wherein the vinyl copolymer resin (A) comprises a (meth)acrylate structural unit (a) represented by the following formula (1):
A thermoplastic resin laminate formed of a methacrylic resin (B) layer, a thermoplastic resin (C) layer comprising a methyl methacrylate-styrene copolymer or an acrylonitrile-styrene copolymer and being laminated on one side or both sides of the methacrylic resin (B) layer, and a vinyl copolymer resin (A′) layer further laminated thereon, wherein the vinyl copolymer resin (A′) comprises a (meth)acrylate structural unit (a) represented by the formula (1), and an aliphatic vinyl structural unit (b) represented by the formula (2);
