Abstract
A pot-stable photopolymerizable composition for forming a cosmetic coating for nails comprises a mixture of a poly(alkyl(meth)acrylate powder, (meth)acrylate oligomer, (meth)acrylate monomer, a crosslinker, and a photoinitiator. This composition exhibits high viscosity that resembles the viscosity of a workable two part system after the monomer liquid and the polymer have been mixed. This composition can be shaped to form nail coatings without any additional use of monomers liquid, followed by an exposure to UV light to photopolymerize the composition to create a hard, durable nail coating. Additional ingredients such as colorants and antioxidants may be included in the composition of the present invention.
