Title:
COATING COMPOSITION, DECORATIVE FILM AND DECORATIVE MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/235345
Kind Code:
A1
Abstract:
The present invention provides an ionizing radiation curable coating composition which is capable of forming a cured film that exhibits excellent elongation under heating (for example, 30% or more), while having excellent solvent resistance and chemical resistance, and which is able to contain an alcohol as a diluent solvent. The present invention is an ionizing radiation curable coating composition. The present invention contains a urethane (meth)acrylate oligomer (A1) which has six or more (meth)acryloyl groups and a weight average molecular weight of from 3,000 to 50,000; and the urethane (meth)acrylate oligomer (A1) is a silicone-modified oligomer that has a constituent unit (a) derived from a polyfunctional (meth)acrylate monomer having a hydroxyl group and three or more (meth)acryloyl groups, a constituent unit (b) derived from an alcohol having two or more hydroxyl groups and a molecular weight of 100 or less, a constituent unit (c) derived from isophorone diisocyanate, and a constituent unit (d) derived from a carbinol-modified polysiloxane.
