Abstract

To provide a resin composition with antistatic properties and resistance to thermal discoloration.SOLUTION: A resin composition contains a resin main material containing a rubber-reinforced resin (G), an antistatic agent (E), and alkyl phosphate (F). Preferably the alkyl phosphate (F) includes a C1-30 alkyl group. An example of the antistatic agent (E) is a polyether ester amide. The resin composition may further contain a thermoplastic resin (Z) other than the rubber-reinforced resin (G) and the antistatic agent (E).SELECTED DRAWING: None
