Estimating the term…
A 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 defects do not occur during lamination of a hard coating layer; and a molded article obtained by molding the laminated sheet. A synthetic resin laminated sheet has a coating layer, which includes an acrylic resin, laminated on one surface of a substrate layer including a polycarbonate resin in which a monohydric phenol represented by general formula (1) is used as a chain terminator and is obtained by reacting the 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).
A laminated synthetic resin sheet comprising a coating layer containing an acrylic resin (B) on at least one surface of a substrate layer containing a polycarbonate resin (A) with a viscosity-average molecular weight of 18,000-35,000 that is produced by reacting a dihydric phenol and a carbonate binder using a monohydric phenol represented by formula (1) below as a terminating agent:
A laminated synthetic resin sheet comprising a coating layer containing an acrylic resin (B) laminated on at least one surface of a substrate layer containing a polycarbonate resin (A) with a viscosity-average molecular weight of 18,000-35,000 and having a terminal group represented by formula (1-a) below resulting from a monohydric phenol terminating agent:
