Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A thermosetting coating composition comprising an aqueous dispersion of a copolymer of (a) acetoacetoxy ethyl acrylate or methacrylate, (b) glycidyl acrylate or methacrylate, (c) an ethylenically unsaturated polymerizable acid, and (d) a monomer copolymerizable therewith wherein (a) and (b) are present in the weight ratio of less than or equal to 0.5 or greater than 1.5, wherein (b) and (c) are present in the weight ratio of greater than 1.5, wherein the total weight percent of (a), (b) and (c) in the polymer is at least about 8 and not more than about 60 weight percent, wherein (d) is present in the amount of about 40 to about cm 92 weight percents and wherein the pH is about 8.5 to about 10.
Claim 2
Dependent Claim
122 words
A thermosetting coating composition comprising an aqueous dispersion of a copolymer of (a) acetoacetoxy ethyl acrylate or methacrylate, (b) glycidyl acrylate or methacrylate, (c) an ethylenically unsaturated polymerizable acid, and (d) a monomer copolymerizable therewith wherein (a) and (b) are present in the weight ratio of less than or equal to 0.5 or greater than 1.5, wherein (b) and (c) are present in the weight ratio of greater than 1.5, wherein the total weight percent of (a), (b) and (c) in the polymer is at least about 8 and not more than about 60 weight percent, wherein (d) is present in the amount of about 40 to about cm 92 weight percents and wherein the pH is about 8.5 to about 10.
