High rigidity and impact resistance resin composition

A polyamide resin composition comprising

• (A) at least one polyamide resin component selected from the group consisting of
• a polyamide resin and
• a resin composition comprising
• (i) at least 80 weight % of a polyamide resin and
• (ii) the remainder being another thermoplastic resin selected from the group consisting of polypropylene, an ABS resin, polycarbonate, polyethyleneterephthalate and polybutyleneterephthalate;
• (B) a layered silicate having a thickness of 6 to 20.ANG., a length of one side of 0.002 to 1 .mu.m and being uniformly dispersed in the component (A) with a weight ratio of 0.05 to 30 parts by weight of (B) per 100 parts by weight of (A);
• and respective layers of silicate being positioned apart from each other by 20.ANG. or more on an average;
• and
• (C) an impact resistance improving material selected from the group consisting of:
• impact resistance improving materials comprising copolymers obtained from ethylene, unsaturated carboxylic acid and unsaturated carboxylic acid metal salt;
• impact resistance improving materials comprising olefin copolymers containing 0.01 to 10 mole % of acid groups;
• and
• impact resistance improving materials comprising block copolymers, containing 0.01 to 10 mole % of acid groups, obtained from vinyl aromatic compounds and conjugated diene compounds, hydrogenated products of said block copolymers or mixtures thereof,
• wherein there are 5 to 70 parts by weight (c) per 100 parts by weight of (A).
