    • Provided is a thermoplastic resin laminate including: a thermoplastic transparent resin (A) layer; a thermoplastic resin (B) layer formed of a methyl methacrylate-styrene copolymer and/or an acrylonitrile-styrene copolymer; and a thermoplastic resin (C) layer formed of a polycarbonate-based resin, the (B) layer being laminated on one surface, or each of both surfaces, of the (C) layer, and the (A) layer being laminated on the surface of the (B) layer, in which the thermoplastic transparent resin (A) includes a vinyl copolymer resin containing a (meth)acrylate constituent unit (a) and an aliphatic vinyl constituent unit (b) each having a specific structure at a molar ratio between the (meth)acrylate constituent unit (a) and the aliphatic vinyl constituent unit (b) of 15:85 to 85:15. The thermoplastic resin laminate has such characteristics as to be excellent in, for example, weather resistance against high-temperature, high-humidity environments, abrasion resistance, and interlayer adhesion, and is used, as a transparent substrate material or a transparent protective material, for an optical product, and in particular, portable display devices such as portable phone terminals, portable electronic game devices, and PDA's.
    • 本发明提供一种热塑性树脂层压体,它包括:热塑性透明树脂(A)层; 由甲基丙烯酸甲酯 - 苯乙烯共聚物和/或丙烯腈 - 苯乙烯共聚物形成的热塑性树脂(B)层; 和由(C)层和层叠在所述(C)层上的所述(A)层的一个表面或两个表面层叠的所述(B)层,由聚碳酸酯类树脂形成的热塑性树脂(C) (B)层,其中热塑性透明树脂(A)包含含有(甲基)丙烯酸酯结构单元(a)的乙烯基共聚物树脂和脂族乙烯基构成单元(b) (甲基)丙烯酸酯结构单元(a)和脂族乙烯基构成单元(b)之间的比例为15:85至85:15。 热塑性树脂层叠体具有例如耐高温,高湿度环境的耐候性,耐磨性和层间粘合性优异的特征,作为透明基材或透明保护材料, 用于光学产品,特别是诸如便携式电话终端,便携式电子游戏设备和PDA的便携式显示设备。
