Title:
Active energy-rays hardenability constituent
Document Type and Number:
Japanese Patent JP6111592
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition capable of providing a coating film having low tackiness before curing, low curling property of a cured film after curing, good in surface hardness, excellent in flexibility and further having low heat curling property in a heating process after curing.SOLUTION: An active energy ray-curable composition contains 50 to 95 mass% of a polymer (A) manufactured by an addition reaction of a glycidyl (meth)acrylate polymer and (meth)acrylic acid and having a radical polymerizable unsaturated group having an unsaturated group equivalence of X (g/eq), and 5 to 50 mass% of a polyfunctional monomer (B) having 3 or more (meth)acryloyl groups in a molecule, and a weight average molecular weight (Mw) of the polymer (A) satisfies a requirement of the formula (1). Formula (1): 60X+80,000≤Mw≤500,000, where the unsaturated group equivalence X is 200 to 3000.
