Patent ID: 8592040

Claim:
A binder or coating formulation, comprising a copolymer derived from: at least one vinyl ester of formula I: CH 2 ═CR 1 —O—CO—R 2 , (I) wherein R 1 is H or CH 3 and R 2 is C 6 -C 12 branched or straight chain alkyl at least one copolymerizable surfactant of formula II, or salt thereof: wherein R 1 represents a branched aliphatic hydrocarbon group, a secondary aliphatic hydrocarbon group or a branched aliphatic acyl group, AO and AO′ each independently represent an oxyalkylene group having 2 to 4 carbon atoms, R 2 and R 3 each independently represent a hydrogen atom or a methyl group, x stands for a number of from 0 to 12, y stands for a number of 0 to 1, z stands for a number of from 1 to 10, X represents a hydrogen atom or an ionic hydrophilic group, m stands for a number of from 0 to 1,000, and n stands for a number of from 0 to 1,000; and optionally at least one additional co-monomer, wherein the binder or coating formulation is substantially free of surfactants not co-polymerized with the copolymer.
