Composition of polyamide, polyester and glycidyl vinylic copolymer

A resin composition for molding, comprising 100 parts by weight of a mixture comprising:

• (A) 30 to 70% by weight of a polyamide resin having terminal carboxyl groups and terminal amino groups, and having a molar ratio of the terminal carboxyl group to the terminal amino group of 1.5 or more, and
• (B) 70 to 30% by weight of a thermoplastic polyester resin, and incorporated therein, and
• (C) 0.1 to 10 parts by weight, based on 100 parts by weight of components (A) and (B), of a vinylic copolymer consisting essentially of 40 to 99% by weight of at least one vinyl monomer represented by formula (I) and 60 to 1% by weight of at least one vinyl monomer having a glycidyl ester group represented by formula ##STR4## wherein R.sub.1 represents a hydrogen atom or a lower alkyl group;
• R.sub.2 represents a phenyl group, a cyano group or an alkyl ester group in which the alkyl group has 1 to 10 carbon atoms;
• and R.sub.3 represents a hydrogen atom or a lower alkyl group.
