Abstract
Abstract A combination of a human nail and an artificial nail cover are coated by (1) first applying to the surface of the combination a monomeric aliphatic or cycloaliphatic hydrocarbon urethane dimethacrylate, a photo cure system and methacrylic acid and then curing in the visible light range and then applying a composition of the monomeric urethane or methacrylate, a polymeric aliphatic of cycloaliphatic hydrocarbon urethane acrylate methacrylate, a low viscosity polyglycol dimethacrylate and a photo cure system and curing in the visible range.
