ACTINIC RAY-CURABLE COATING COMPOSITION AND METHOD FOR FORMATION OF COATING FILM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an actinic ray-curable coating composition capable of forming a cured coating film with good storage stability, good curing properties and hardness and fine appearance. SOLUTION: The actinic ray-curable composition consists of: (A) a polymer having at least one oxetanyl groups and one radical-polymerizable double bonds within each polymer; and (D) a polymerization initiator or a polymerization initiator mixture which generates cations and free radicals when irradiated with actinic ray. The coating method consists of applying the composition on the surface of a material to be coated and then curing the composition by irradiation with actinic ray.
