PHOTOCURABLE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a photocurable resin composition wherein the synthesis of a resin is simple and convenient and the ink sensitivity and the tack property shown by step grading evaluation can be balanced. SOLUTION: The composition contains a monomer composition having a terminal carboxyl group in which a terminal hydroxy (meth)acrylate obtained by adding to hydroxyalkyl (meth)acrylate of 1 mol a ε-caprolactone monomer at a ratio of less than 1 mol is acid-anhydride-modified. Alternatively, it contains a monomer composition which has a terminal carboxyl group obtained by adding to a (meth)acrylic acid the monomer at the same ratio.
