<p>The invention provides a novel antistatic agent which has good intermiscibility with an active energy ray gel-type resin in composition with poly(methyl)acrylate compound and other active energy ray gel-type resin as main components, and the antistatic agent can restrain water-absorbing property of the resin composition, and also restrain anti-static function reduction of solidified skin obtained by the resin composition. The antistatic agent used for the active energy ray gel-type resin composition contains vinyl monomers (a1) with quaternary ammonium salt structure, vinyl monomers (a2) which is formed by opening loop and polymerizing vinyl monomers containing hydroxyl and lactones, weight-average molecular weight of the vinyl monomers (a2) is 4000-10000, chain-shaped alkyl ester groups with carbon number of 3-5, and vinyl monomers (a3) without alicyclic structure, and a copolymer (A) which is obtained by reaction of other vinyl monomers (a4) which is used as needed.</p> |
