ABSTRACT:
A copolymer containing a hydroxy and a carboxyl moiety and is dilutable with water after neutralization with an organic base, which copolymer is from an alkyl ester and/or hydroxyalkyl ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid in which the alkyl moiety is interrupted by one or more oxygen atoms and the alkyl moiety of the hydroxyalkyl ester can contain one or more hydroxyl groups, an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and an optionally copolymerizable vinyl monomer, and has an acid number of from about 20 to about 50, and an OH number of from about 40 to about 90, and contains incorporated by polymerization from about 0.5 to about 5% wt. based on the monomers used for its preparation of one or more perfluoroalkyl ethyl ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid containing a C.sub.6-18 alkyl moiety.
