Ultraviolet-curable composition and use thereof

Abstract

Provided is an ultraviolet-curable composition containing silicon atoms, wherein the composition has a high ability to adjust the mechanical properties of the cured product thereof, and has excellent workability and high adhesion to a substrate even for solvent-free application. This disclosure provides an ultraviolet-light curable composition and a use thereof. The composition contains: (A) 1-99 parts by mass of a compound having at least one (meth)acryloxy group and hydroxyl group in one molecule and having no silicon atom; (B) 1-99 parts by mass of an organopolysiloxane having at least two alkenyl groups in one molecule and having no ultra-violet-curable functional group; and (C) 0-80 parts by mass of a compound having at least one (meth)acryloxy group in the molecule and having no hydroxyl group, on the basis of 100 parts by mass of the total mass of the composition, and contains substantially no organic solvent in the composition.
