An aqueous dispersion of 0.1 to 15 percent by weight of at least one phosphate ester and a copolymer formed by the coploymerization of a monomer mixture comprising: a) 0.1 to 15 percent by weight of at least one dicarboxylic acid, b) 0.1 to 10 percent by weight of at least one functional monomer is represented by the following formula: where R1, R2 and R3 are hydrogen or a methyl group, R4 is an alkyl containing 1 to 4 carbon atoms, n is 0 or 1, X is selected from the group consisting of hydrogen, carboxyl, phenyl, aryl, alkyl or alkaryl groups containing 1 to 30 atoms, and Y is a nucleophilic group selected from -OH, -NH2 or or wherein R5 is a hydrogen, an alkyl containing 1-20 carbon atoms, or an aryl group, and c) more than 80% by weight of backbone monomers.
