Abstract
An aromatic polycarbonate resin composition comprising:100 parts by weight of a resin component consisting of (1) 50 to 100 wt % of an aromatic polycarbonate resin (component A) and (2) 0 to 50 wt % of at least one thermoplastic resin (component B) selected from the group consisting of a thermoplastic polyester resin (component B-1) and a styrene unit component-containing resin having a rubber component content of less than 40 wt % (component B-2); and(3) 1 to 100 parts by weight of wollastonite particles having such particle shape characteristics that the particles have a number average fiber length measured by a method specified in this text of 10 &mgr;m or less and a number average fiber diameter measured by a method specified in this text of 4 &mgr;m or less and include particles having a fiber length of 5 to 25 &mgr;m in a number proportion of less than 50% of the total and moldings thereof. According to the present invention, there are provided an aromatic polycarbonate resin composition which has high stiffness, high impact resistance, a good surface appearance (suppression of the formation of projecting foreign matter which causes deterioration in coating appearance) and re…
