Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
A radiation curable composition comprising the reaction product of (a) an acrylate copolymer containing pendant glycidyl ester groups, and (b) acrylic acid or methacrylic acid plus (c) phosphoric acid wherein the acrylate copolymer (a) is a copolymer of about 5 to about 75 weight percent, based on the total weight of the copolymer, glycidyl acrylate or methacrylate with the remainder being an ethylenically unsaturated monomer copolymerizable therewith, wherein (b) is reacted with the glycidyl ester groups in the amount of about 25 to about 75 percent of the equivalents of the glycidyl ester groups, and wherein (c) is reacted with the remainder of the glycidyl ester groups in the amount of about 0.5 to about 1 mole per glycidyl ester group in the presence of at least about one equivalent of hydroxyl group-containing material per mole of (c).
Claim 2
Dependent Claim
138 words
A radiation curable composition comprising the reaction product of (a) an acrylate copolymer containing pendant glycidyl ester groups, and (b) acrylic acid or methacrylic acid plus (c) phosphoric acid wherein the acrylate copolymer (a) is a copolymer of about 5 to about 75 weight percent, based on the total weight of the copolymer, glycidyl acrylate or methacrylate with the remainder being an ethylenically unsaturated monomer copolymerizable therewith, wherein (b) is reacted with the glycidyl ester groups in the amount of about 25 to about 75 percent of the equivalents of the glycidyl ester groups, and wherein (c) is reacted with the remainder of the glycidyl ester groups in the amount of about 0.5 to about 1 mole per glycidyl ester group in the presence of at least about one equivalent of hydroxyl group-containing material per mole of (c).
