Active energy ray curable composition, active energy ray curable coating and active energy ray curable printing ink using the same

摘要

Provided is an active energy ray-curable composition which is characterized by being obtained by reacting (A) a polyfunctional acrylate, (B) an aromatic dicarboxylic acid and (C) an aromatic epoxy resin, and then reacting the obtained reactant with (D) a carboxylic acid having a polymerizable unsaturated group. In cases where this active energy ray-curable composition is used in a coating material such as a hard coat agent, this active energy ray-curable composition is capable of providing a cured film of the coating material with high scratch resistance. Consequently, this active energy ray-curable composition is suitable as a material for a hard coat agent that forms a protective film on the surface of an article. In cases where this active energy ray-curable composition is used in a printing ink, this active energy ray-curable composition is capable of providing the ink with high anti-misting properties and is also capable of providing a cured film of the printing ink with high adhesion to a base and high solvent resistance. Consequently, this active energy ray-curable composition is suitable as a binder for various printing inks such as a lithographic printing ink and a gravure printing ink.
