"LATEX NAIL COATING" Hector J. Gonzalez and Janiana Z. Pilch ABSTRACT OF THE DISCLOSURE An aqueous latex nail coating emulsion of copolymers of at least three monomers and methods of formulating such coating are disclosed. One monomer comprises at least one or .beta. mono ethylenically unsaturated mono or polycarboxylic acid monomer having from 3-10 carbon atoms. A second monomer comprises at least one ethylenically unsaturated ester. The third monomer comprises at least one additional monomer of an ethylenically unsaturated ester other than the last mentioned ester monomer, a monovinylidene, a vinyl ester or an acrylamide. Emulsifying agents may be added to emulsify these monomers in the aqueous emulsion and at least some of these emulsifiers may be copolymerizable with the monomers. Following copoly- merization, a salt of a di- or trivalent metal is added to the emulsion for crosslinking the copolymers. Following copoly- merization, one or more alkali soluble resins, plasticizing agents, coalescing agents, antifoaming agents, viscosifying agents, leveling aids and pigments may also be added, as desired, to form the nail coating.
