Polyarylene sulfide resin composition and coated molding

The present invention is improved in an enhanced impact resistance of a molded article of a PAS resin and continuous molding (mold release improvement) in mass production and adhesion to coating. The present invention provides a polyarylene sulfide resin composition comprising (A) 100 parts by weight of a polyarylene sulfide resin, (B) 1-20 parts by weight of a graft copolymer formed by the branching or crosslinking chemical bond of an olefin-based copolymer (b-1) and at least one polymer or copolymer (b-2), the olefin copolymer (b-1) composed mainly of an alpha-olefin and an alpha, beta-unsaturated carboxylic acid ester without a glycidyl group, the polymer or copolymer (b-2) constituted of a specific repeating unit, and (C) 1-20 parts by weight of an olefin copolymer composed mainly of an a-olefin and a glycidyl ester of an alpha,beta-unsaturated carboxylic acid.
