Document Type and Number:
Japanese Patent JP4253896
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated structure made of a thermoplastic resin excellent in both of rigidity and impact resistance and low in the coefficient of linear expansion and a method for producing the same. SOLUTION: A laminated structure is constituted of at least two layers, that is, a layer comprising (A) a thermoplastic resin having a fusion main peak temp. of Tma( deg.C) and a layer comprising (B) a thermoplastic resin having a fusion main peak temp. of Tmb( deg.C). In this case, at least two multilayered stretched films wherein Tma( deg.C) and Tmb( deg.C) satisfy a relation of Tma< Tmb-5( deg.C) are integrally laminated.
