Abstract:
1. A method of preparing colored ultraviolet (UV)-curable compositions useful for adornment of natural and artificial nails and artificial nail extensions comprising dispersing a pigment in an organic liquid to form a pigment concentrate, the organic liquid comprised of one or more organic chemicals selected from solvents, ethylenically unsaturated monomers, and ethylenically unsaturated oligomers; and mixing the dispersed pigment concentrate with a radiation-curable nail gel composition consisting essentially of one or more ethylenically unsaturated monomers, one or more ethylenically unsaturated oligomers, or mixtures thereof, a photoinitiator and, optionally, one or more photo accelerators, fillers, inhibitors, plasticizers, non-reactive polymers, and adhesion promotors; the resultant mixture adapted to be curable in the presence of UV radiation.
