Abstract
The present invention relates to coating compositions that include an admixture or blend of at least two solution copolymers that provide combinations of properties which are not possessed by coating compositions that include only one of the copolymers. Each solution copolymer contains at least one aromatic monoethylenic monomer and at least one monoethylenic ester in amounts sufficient to provide a first solution copolymer having a glass transition temperature between about 40 and 70 degrees Centigrade and a second solution copolymer having a glass transition temperature between about -10 and +10 degrees Centigrade. Pigments can be readily wetted and dispersed in the copolymer blend to provide stable pigment concentrates that are useful in the preparation of coating compositions suitable for use on human fingernails.
