    Abstract: The present invention provides a composition for preventing adhesion of air-borne fine particles, which contains a 2-(meth)acryloyloxyalkyl phosphorylcholine-(meth)acrylic acid alkyl ester copolymer as an antistatic agent, and which is not decreased in the effect of preventing adhesion of air-borne fine particles even if a sufficient amount of an oil component is blended therein. The present invention is characterized by containing (A) 2-(meth)acryloyloxyalkyl phosphorylcholine-(meth)acrylic acid alkyl ester copolymer, (B) a di-long-chain cationic surfactant represented by formula (I) (wherein each R1 independently represents and alkyl group having 12-22 carbon atoms and 0-3 double bonds; each R2 independently represents an alkyl group having 1-3 carbon atoms and no double bond; and Y represents a halogen atom, a methosulfate or a methophosphate), and (C) one or more oil components selected from among hydrocarbon oils, ester oils and silicone oils.
