PHOTOCURABLE COATING MATERIAL

Document Type and Number:

WIPO Patent Application WO/2007/116704

Kind Code:

A1

Abstract:

Disclosed is a photocurable coating material which is cured by ultraviolet light, electron beam, radiation or the like. This coating material is excellent in thermal discoloration resistance, adhesion to a base, abrasion resistance, water resistance and impact resistance. Specifically disclosed is a photocurable coating material characterized by containing 5-95 parts by weight of a urethane acrylate (U), 5-95 parts by weight of an acrylate compound (M) and 0.1-15 parts by weight of a photoinitiator (C) per 100 parts by weight of the total of the components (U) and (M). This photocurable coating material is also characterized in that the urethane acrylate (U) contains at least one or more diisocyanates (a) selected from the group consisting of hydrogenated xylylenediisocyanate and hydrogenated methylene bisphenylene diisocyanate, and a compound (b) containing a hydroxyl group and a (meth)acrylate group. The photocurable coating material is further characterized in that the acrylate compound (M) has two or more acrylate groups in a molecule with an acrylate group content of 5-12 mmol/g, while containing no aromatic ring structure.
