ABSTRACT:
An improved nail lacquer containing a film forming resin, a plasticizer, and a solvent. The improvement resides in utilizing as the film forming resin a blend of: (i) a graft copolymer having a main backbone chain of acrylic ester units and methacrylic ester units, with the main backbone chain having grafted thereto pendant trialkoxysilyl groups and pendant ethylene glycol dimethacrylate groups; and (ii) a silsesquioxane resin containing RSiO.sub.3/2 units and .tbd.SiOH units in which R is an alkyl group or an aryl group. In an alternate form of the invention, the film forming resin is not a blend, but an improved type of graft copolymer containing, in addition to pendant trialkoxysilyl groups, pendant vinylbenzyl chloride groups.
