Abstract
Abstract An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) a reaction product of a novolak-epoxy compound and an unsaturated monocarboxylic acid, (b) a reaction product of a diisocyanate and a poly(meth)acrylate having a hydroxyl group per moleucle and (c) at least one of an aromatic, aliphatic or alicyclic polybasic acid (or an anhydride thereof).

An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) a reaction product of a novolak-epoxy compound and an unsaturated monocarboxylic acid, (b) a reaction product having one isocyanate group of a diisocyanate and a poly(meth)acrylate having a hydroxyl group per molecule and (c) at least one of an aromatic, aliphatic or alicyclic polybasic acid or an anhydride thereof.
Claim 3
Dependent Claim
40 words
An activation energy-curable resin composition according to claim 1, wherein said reaction product (a) of the novolak-epoxy compound and the unsaturated monocarboxylic acid is obtained by the addition reaction of a polycondensate of phenol and formaldehyde with epichlorohydrin or β-methylepichlorohydrin.
Claim 4
Dependent Claim
50 words
An activation energy-curable resin composition according to claim 1, wherein said reaction product (a) of the novolak-epoxy compound and the unsaturated monocarboxylic acid is obtained by the addition reaction of a polycondensate of an alkyl phenol having a C 1 -C 9 alkyl group and formaldehyde with epichlorohydrin or β-methylepichlorohydrin.
Claim 5
Dependent Claim
27 words
An activation energy-curable resin composition according to any one of claims 1, 2 or 3 wherein said novolak-epoxy compound contains from 3 to 8 phenol nucleus residues.
Claim 6
Dependent Claim
24 words
An activation energy-curable resin composition according to claim 1 wherein the unsaturated monocarboxylic acid is acrylic acid, methacrylic acid, crotonic acid or cinnamic acid.
Claim 7
Dependent Claim
50 words
An activation energy-curable resin composition according to claim 1, wherein the reaction product (a), the novolak-epoxy compound and the unsaturated monocarboxylic acid are reacted at an equivalent ratio of the epoxy group of the novolak-epoxy compound to the carboxyl group of the monocarboxylic acid in the range of from 1.0-1.7:1.0.
Claim 8
Dependent Claim
