An antistatic agent for an active energy ray-curable resin composition, an active energy ray-curable resin composition, a cured product and a film. The present disclosure relates to a structural unit (a1) derived from a vinyl monomer containing a quaternary ammonium salt structure, a ring-opening polyadduct of a hydroxyl group-containing vinyl monomer and a lactone, and having a weight average molecular weight of 1,000. It includes a constituent unit (a2) derived from a vinyl monomer which is ~ 10,000 and a constituent unit (a3) derived from a vinyl monomer containing a branched alkyl ester group having 3 to 5 carbon atoms, and the molecular weight distribution (Mw / Mn) is 1 Antistatic agent for active energy ray-curable resin composition containing polymer (A), which is from 8 to 5.0, active energy ray-curable resin composition containing the above antistatic agent, cured product of the above composition And a film comprising the above cured product. 【Selection chart】 None |
