摘要： The present invention provides: a new synthetic resin laminated sheet in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and in which defects similarly do not occur during lamination of a hard coating layer; and a molded article obtained by molding said laminated sheet. Provided is a synthetic resin laminated sheet which has a coating layer, which is configured to include an acrylic resin (B), laminated on one surface of a substrate layer comprising a polycarbonate resin (A) in which a monohydric phenol represented by general formula (1) is used as a chain terminator and which is obtained by reacting said monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).
摘要翻译：本发明提供：一种新的合成树脂层压板，其中当进行热成形时，尤其是当进行深拉成型时不发生白化，开裂和发泡，并且其中在层压过程中类似地不发生缺陷硬涂层; 以及通过模制所述层压片而获得的模制品。本发明提供一种合成树脂叠层片，其具有在由聚碳酸酯树脂（A）构成的基材层的一个面上层叠有丙烯酸树脂（B）而成的被覆层，所述聚碳酸酯树脂（A） 1）用作链终止剂，其通过使所述一元酚与二元酚和碳酸酯粘合剂反应而获得并且具有18000-35000的粘均分子量。（式中，R 1表示碳原子数8〜36的烷基或碳原子数8〜36的烯基，R 2〜R 5分别表示氢原子，卤原子或可以具有取代基的碳原子数1〜20的烷基或碳原子数6〜12的芳基。
