ABSTRACT A solution copolymer of styrene or vinyl toluene and allyl or methallyl alcohol is esterified with from 20% to 65% of the weight of the ester with ethylenically unsaturated monocarboxylic fatty acid containing from 8 to 22 carbon atoms. This ester is then copolymerized with monoethylenically unsaturated monomers including from about 2% to about 15%, based on the total weight of the final copolymer, of a monoethylenically unsat- urated carboxylic acid to provide a copolymer which dissolves in water with the aid of a volatile base and which is particularly useful in pigmented latex paints.
