Claim 1
Independent Claim
66 words
A water dispersed coating composition containing a polymeric binder, the binder polymer comprising copolymerized ethylenically unsaturated monomers and on polymeric solids weight basis: copolymerized monomers comprising between 1% and 20% alkylated alkylol acrylamide monomer, between 1% and 15% functional monomer selected from reactive carboxyl, hydroxyl, amine, or amide functional group monomer, and between 0.1% and 10% phosphate monomer, with the balance being other ethylenically unsaturated monomer.
Claim 2
Dependent Claim
66 words
A water dispersed coating composition containing a polymeric binder, the binder polymer comprising copolymerized ethylenically unsaturated monomers and on polymeric solids weight basis: copolymerized monomers comprising between 1% and 20% alkylated alkylol acrylamide monomer, between 1% and 15% functional monomer selected from reactive carboxyl, hydroxyl, amine, or amide functional group monomer, and between 0.1% and 10% phosphate monomer, with the balance being other ethylenically unsaturated monomer.
Claim 3
Dependent Claim
17 words
The coating composition in claim 1 wherein the phosphated monomer comprises an hydroxy alkyl phosphate ester monomer.
Claim 4
Dependent Claim
21 words
The coating composition in claim 1 wherein the phosphated monomer is a phosphoric acid ester of an hydroxyl acrylate or methacrylate.
Claim 5
Dependent Claim
17 words

Claim 6
Dependent Claim
44 words
The coating composition in claim 1 wherein the phosphated monomer is prepared by reacting an acrylic acid derivative with a glycol to produce a glycol ester monomer, and then phosphating the glycol ester monomer with a phosphoric acid derivative to produce a phosphated monomer.
Claim 7
Dependent Claim
43 words
The composition in claim 1 wherein the phosphated monomer is prepared by reacting an arcylic acid derivative with epoxy resin to produce an epoxy ester monomer, and then phosphating the epoxy ester monomer with a phosphoric acid derivative to produce a phosphated monomer.
Claim 8
Dependent Claim
58 words
