Abstract The present invention relates to a novel coating composition which contains a coalescent. The coating composition comprises a latex of a normally solid organic addition polymer and a coalescing amount of an ether-ester solvent having formula (I) or (II) ##STR1## where R represents hydrogen or an alkyl group of 1 to 4 carbon atoms, R' represents a C 1 -C 4 alkyl group, and n is 1 or 2. Preferred coalescents include 2-ethoxyethyl p-toluate, 2-ethoxyethyl benzoate, 2-(2-ethoxyethoxy)ethyl p-toluate, 2-(2-ethoxyethoxy)ethyl benzoate, 2-propoxyethyl o-toluate, 2-propoxyethyl benzoate, 2-ethoxyethyl o-toluate, 2-methoxy-1-methylethyl benzoate and mixtures thereof. In preferred embodiments, the organic addition polymer comprises an acrylic homopolymer or copolymer. The coating composition preferably comprises about 5-50 parts by weight of the ether-ester solvent per 100 parts of the organic addition polymer.
A coating composition comprising a latex of a normally solid organic addition polymer and a coalescing amount of at least one ether-ester solvent having the formula ##STR4## where R represents hydrogen or an alkyl group of 1 to 4 carbon atoms, R' represents a C 1 -C 4 alkyl group, and n is 1 or 2.
