Document Type and Number:
Japanese Patent JP2956254
Kind Code:
B2
Abstract:
A laminated polyphenylene sulfide film wherein the central layer comprises a biaxially oriented polyphenylene sulfide film and the surface layer comprises a phenylene sulfide copolymer containing a comonomer unit other than a p-phenylene sulfide unit in an amount of 3 to less than 50 mole %.
