The present invention provides a composition which is a composition for preventing the adhesion of fine particles in the air containing 2- (meth) acryloxyalkyl phosphate choline-alkyl (meth) acrylate copolymer as an antistatic agent And even if a sufficient amount of oil is blended, the effect of preventing the adhesion of fine particles in the air will not be reduced. The main purpose of the present invention is to contain: (A) 2- (meth) acryloyloxyalkylphosphocholine-alkyl (meth) acrylate copolymer, (B) A double long-chain cationic surfactant represented by the following formula (I): [In formula (I), R 1 independently represents an alkyl group having 12 to 22 carbon atoms and 0 to 3 double bonds； R 2 independently represents a carbon atom having 1 to 3 carbon atoms and has no double bonds Alkyl； Y represents a halogen atom, methyl sulfate, or methyl phosphate], and (C) One or more oils selected from hydrocarbon oil, ester oil and silicone oil.本發明提供一種組合物，其係含有2-(甲基)丙烯醯氧基烷基磷酸膽鹼-(甲基)丙烯酸烷基酯共聚物作為抗靜電劑之空氣中微粒子附著防止用組合物，且即便調配有足夠量之油分，其防止空氣中微粒子附著之效果亦不會降低。本發明之主旨在於含有：(A)2-(甲基)丙烯醯氧基烷基磷酸膽鹼-(甲基)丙烯酸烷基酯共聚物、(B)以下之式(I)所表示之雙長鏈型陽離子界面活性劑：[式(I)中，R1分別獨立地表示碳原子數為12～22且具有0～3個雙鍵之烷基；R2分別獨立地表示碳原子數為1～3且未具有雙鍵之烷基；Y表示鹵素原子、硫酸甲酯、或磷酸甲酯]、及(C)選自烴油、酯油、矽酮油之1種以上之油分。
