Abstract
A photo-reactive nail polish coating composition that cures quickly upon exposure to low levels of ultraviolet radiation. The coating consists of a polymer formed from a composition comprising nitrocellulose, a photo-reactive monomer, a photoinitiator and a reaction inhibitor, resulting in a product compatible with commercially available nail polish of any color and removable by standard acetone-based polish removers. It is also compatible with every-day chores because it is insoluble in water. The composition is not phototoxic and has very low potential for skin irritation or sensitization. The photo-reactive coating is applied over the wet nail polish and then irradiated with safe dosages of ultraviolet radiation, causing the nail polish to dry in a few minutes.
