URETHANE HARD COATING RESIN COMPOSITION AND COATED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide urethane hard coating resin compositions which inhibit foaming under hot and humid conditions and have sufficient working life, and coated materials. SOLUTION: The urethane hard coating resin compositions comprise (A) a compound composed of (a-1) a liquid bisphenol type epoxy ester modified polyol having two or more secondary hydroxy groups and (a-2) a natural oil or its derivative at a hydroxyl group equivalent % of (a-1) to (a-2) of 4/6 to 6/4 and (B) a polyisocyanate compound as the essential components.
