<p>PROBLEM TO BE SOLVED: To obtain the subject composition excellent in adhesion to substrates such as a plastic film or a metal and useful as a film-forming material for coating materials, inks or the like, or a resin material for encapsulants, molding agents, adhesives, tacky agents or the like, by including a specific epoxy acrylate and a polymerizable unsaturated compound. SOLUTION: This composition is obtained by including (A) an epoxy acrylate prepared by reacting (i) an aliphatic epoxy group-containing compound with (ii) a carboxyl group-containing (meth)acrylic compound represented by formulae I to III [(p) and (m) are each 2-20; (q) is 2-15; (n) is 0-10; (r) and (r') are each 1-16; (t) is 5-15; (l) is 1-10; R1 is H or methyl; R2 and R2' are each an organic residue represented by formula IV (R3 is H or a 1-20C hydrocarbon) or the like] and (B) other polymerizable unsaturated compounds. The component (i) is preferably a compound represented by formula V [(s) is 2-25] or the like. The compounding ratio of the components A to B is preferably (10:90) to (95:5) (weight ratio). The component B preferably contains an acrylate- or a methacrylate-based compound having hydroxyl group.</p> |
