Abstract:
A resin sheet for forming is provided which is made of a polycarbonate resin as the main material. Even when thermoformed especially by deep drawing, the resin sheet neither cracks, foams, nor causes whitening. The resin sheet for forming is a layered sheet comprising: a base layer including, as the main component, a polycarbonate resin composition (A) comprising a polymer alloy constituted of an aromatic polycarbonate (A1) and another resin (A2); and a coating layer including an acrylic resin (B) as the main component and superposed on one side of the base layer. The difference in glass transition temperature between the polycarbonate resin composition (A) and the acrylic resin (B) is within 30°C in terms of absolute value.
