ABSTRACT:
The invention relates to an acrylic polymer latex comprising the polymerization product of an acetoacetate moiety of the structure ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and are selected from the group consisting of C.sub.1 -C.sub.22 alkyl groups and X is a halogen, in amounts effective to improve the water resistance of the acrylic latex; and at least one monomer(s) selected from the group consisting of C.sub.3 -C.sub.6 monocarboxylic acids, C.sub.4 -C.sub.6 dicarboxylic acids and their C.sub.1 -C.sub.4 half esters, C.sub.1 -C.sub.10 alkyl esters of acrylic acid, C.sub.1 C.sub.10 alkyl esters of methacrylic acid, styrene, halogenated styrene and substituted styrene and latex compositions containing the novel latexes. The invention also relates to methods of improving the water resistance of the coating compositions which include adding to the coating composition the latex which contains an amount of the acetoacetate moiety effective to improve the water resistance of the coating compositions.
