1. Field of the Invention
The present invention relates to an active energy ray-curable composition and an antistatic film.
2. Description of the Related Art
Generally, resin materials exhibit excellent electrical insulation properties and are therefore very useful for applications requiring electrical insulating properties such as insulators, but surfaces thereof are easily charged with static electricity, which is thus likely to result in dust adsorption and electrostatic troubles.
To solve such problems, it is known to use various antistatic agents (in particular, cationic antistatic agents).
For example, JP2011-225797A discloses an “antistatic coating composition including an antistatic copolymer (A) having a quaternary ammonium base in the molecule, a compound (B) having three or more ethylenically unsaturated groups, a photopolymerization initiator (C) containing a photopolymerization initiator (c-1) having a solubility in water of 0.2 g/L or less and a photopolymerization initiator (c-2) having a solubility in water of 1 g/L or more, and a solvent (D) containing an alcohol-based solvent (d-1)” ([claim 1]), and also discloses that the photopolymerization initiator (C) is “at least one selected from the group consisting of 1-hydroxy-cyclohexyl-phenyl-ketone, 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one, bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide, 2-hydroxy-1-{4-[4-(2-hydroxy-2-methyl-propionyl)-benzyl]-phenyl}-2-methyl-propan-1-one, 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide, oligo {2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone}, and 2,4,6-trimethylbenzophenone” ([claim 4]).
