Patent ID: 8323533

Claim:
A curable resin manufactured by condensation of a composition, wherein the composition comprises: a) a compound represented by the following Formula 1; b) glycidyl (meth)acrylate; c) acid monoanhydride; and d) a solvent: wherein X is hydrogen, C 1 -C 6 alkoxy, phenoxy, C 1 -C 10 alkyl unsubstituted or substituted with halogen, C 2 -C 10 alkenyl containing 1 to 3 unsaturated groups, phenyl, naphthyl, or anthracenyl, Y is C 1 -C 6 alkoxy, phenoxy, C 1 -C 10 alkylene unsubstituted or substituted with halogen, C 2 -C 10 alkenylene containing 1 to 3 unsaturated groups, or phenylene, X and Y may be connected to each other to form a C 5 -C 12 ring, and Z is hydrogen, or straight or branched C 1 -C 10 alkyl which is substituted with a carboxyl group; wherein a molar ratio of the ingredients a) and b) is 5:1 to 0.2:1 and the c) acid monoanhydride is contained in a molar ratio of 0.1 to 1, based on 1 mole of the a) compound, and wherein the curable resin has a weight-average molecular weight of 1,000 to 100,000, and an acid value of 5 to 200 KOH mg/g, and having a (meth)acrylic equivalent of 15 wt % or more.
