CURING COMPOSITION, FORMATION OF CURED FILM USING THE SAME AND CURED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a curing composition excellent in flowability and curability, and usable as a film-forming material such as for inks, as a resin material such as for tack agents by including a specific hemiacetal ester and another (meth)acrylic compound or the like. SOLUTION: This composition is obtained by including (A) a reactive hemiacetal ester prepared by reaction between (i) a carboxyl-bearing (meth) acrylic compound and (ii) a vinyl ether-based compound having two or more vinyl ether groups and (B) another (meth)acrylic compound or vinyl ether-based compound in the weight ratio A/B of (10:90) to (95:5); wherein it is preferable that the component (i) is e.g. a half ester prepared by reaction between a cyclic acid anhydride and a hydroxyl-bearing (meth)acrylate compound, as necessary in the presence of a tertiary amine catalyst.
