Abstract
A layered product is provided which is excellent in heat resistance, difficult to hydrolyze and excellent in weatherability, and has such flexibility that it can hardly crack even when folded, and further is prevented from curling, and thus is excellent in processability, productivity and handleability. The layered product comprises a base layer made of a thermoplastic resin (I) having a glass transition temperature of 120° C. or higher, the base layer being layered on at least one side thereof with a layer made of an aromatic vinyl resin (II) having a lower glass transition temperature than the thermoplastic resin (I). The aromatic vinyl resin (II) is preferably a rubber-reinforced aromatic vinyl resin which contains a rubber-like polymer (a) selected from ethylene-α-olefin rubbers, hydrogenated conjugated diene rubbers, acrylic rubbers, silicone rubbers and silicone/acrylic composite rubbers in an amount of 5-40 parts by mass. The difference in glass transition temperature between the thermoplastic resin (I) and the aromatic vinyl resin (II) is preferably 10° C. or more.
