Improved composition for a fingernail coating having an acrylic binder, a peroxide catalyst, a tertiary amine accelerator, and a polymeric filler at least partially soluble in the coating. The acrylic binder contains a monoethylenically unsaturated monomer comprising at least a major proportion of methoxyethyl methacrylate. A polyfunctional monomer may be present that copolymerizes with the monoethylenically unsaturated monomer, for crosslinking and toughening.
