Title:

THERMOPLASTIC RESIN LAMINATE

Document Type and Number:

WIPO Patent Application WO/2010/024217

Kind Code:

A1

Abstract:

A thermoplastic resin laminate having a thermoplastic transparent resin (A) layer, a thermoplastic resin (B) layer composed of a methyl methacrylate-styrene copolymer and/or an acrylonitrile-styrene copolymer, and a thermoplastic resin (C) layer composed of a polycarbonate resin. The (B) layer is arranged on one or both sides of the (C) layer, and the (A) layer is arranged on the surface of the (B) layer. The thermoplastic transparent resin (A) is a vinyl copolymer resin which contains a (meth)acrylate constituent unit (a) of a specific structure and an aliphatic vinyl constituent unit (b), with the molar ratio of the (meth)acrylate constituent unit (a) to the aliphatic vinyl constituent unit (b) being within the range from 15:85 to 85:15. The thermoplastic resin laminate has excellent weather resistance against high-temperature high-humidity environments, excellent abrasion resistance and excellent interlayer adhesion, and can be used as a transparent substrate material or protective material for optical products, especially for portable display devices such as portable phone terminals, portable electronic game devices and PDA's.
