THERMOPLASTIC RESIN LAMINATE |
摘要 |
<p>To provide a thermoplastic resin laminate which is used as a transparent substrate material or a transparent protective material and which is excellent in transparency, birefringence, and pattern-formability. The thermoplastic resin laminate is a synthetic 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) contains a (meth)acrylate structural unit (a) represented by a specific formula and an aliphatic vinyl structural unit (b) represented by a specific formula; in which the ratio of the sum of the (meth)acrylate structural units (a) and the aliphatic vinyl structural units (b) is 90 to 100 mol% with respect to all the structural units that form the vinyl copolymer resin (A); in which the ratio by mole of the (meth)acrylate structural unit (a) to the aliphatic vinyl structural unit (b) is 65 : 35 to 85 : 15; and in which the methacrylic resin (B) contains a structural unit having no benzene ring in an amount of 90 mol% or more with respect to all the structural units thereof.</p> |
