PHOTOCURABLE PUTTY COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a photocurable putty composition rapidly curable by photo- irradiation while having high opacifying properties and a method for repair coating using the same. SOLUTION: The subject photocurable putty composition comprises an ethylenically unsaturated group-containing compound (A), a photoinitiator (B) and a filler (C), and a urethane (meth)acrylate oligomer obtained by reacting a polyisocyanate bearing at least three isocyanate groups in one molecule with a hydroxyl group-containing (meth)acrylate accounts for 20-90 wt.% of the component (A) in the composition.
