Abstract
A laminated structure comprising, laminated in the order stated, (A) a layer of polycarbonate or a layer of a polyester, (B) a layer of a modified ethylene/alpha-olefin random copolymer, the modified copolymer containing about 0.01 to 10% by weight, based on the trunk ethylene/alpha-olefin random copolymer, of an unsaturated carboxylic acid or its derivative grafted thereto, and having an ethylene content of 75 to 95 mole %, a melt flow rate of 0.1 to 50 g/10 min., a density of 0.850 to 0.905 g/cm.sup.3 and a crystallinity of less than 10%, and (C) a layer of a saponified olefin/vinyl acetate copolymer or a layer of a polyamide resin.
