Abstract
A nail compositions comprising at least one photo-curable polymer dispersed in water (latex), at least one polyurethane non-photo-curable polymer dispersed in water (latex), at least one photo-initiator, optionally at least one plasticizer, optionally a colorant, and water are provided. Also provided are nail composition systems and kits comprising the nail compositions of the invention together with a base coat composition and/or a top coat composition.
