Abstract:
1. A laminate having a core layer and a skin layer on either side of the core layer, wherein the skin layer is formed of a copolymer having a glass transition point of 85° C. or more and 115° C. or below and consisting of 2,6-naphthalene dicarboxylic acid or its lower alkyl ester, terephthalic acid or its lower alkyl ester and ethylene glycol or a polymer alloy having a glass transition point of 85° C. or more and 115° C. or below and consisting of polyethylene terephthalate and polyethylene-2,6-naphthalate, wherein the core layer is formed of a polymer alloy consisting of a thermoplastic polyester resin and a heat-resistant resin, which contains 50 to 65 wt % of the heat-resistant resin having an Izod impact test value of 80 J/m to 850 J/m when tested with a ⅛″ notch under conditions of 23° C. and a relative humidity of 50% and having a glass transition point of 140° C. to 250° C.
