Abstract
Rapid drying top coat used to provide a durable glossy look to manicured nails. The rapid-drying, durable coating composition is comprised of a base resin of cellulose acetate butyrate and an aliphatic ester monomer. Additional components include a film former, a cross-linking agent, an inhibitor to polymerization and a solvent. The rapid drying nail polish top-coat composition cures to a hard durable finish within a few minutes on exposure either to safe dosage of ultraviolet light or any heat source depending whether the formulation contains a photoinitiator or thermal initiator. This process of curing also aids in drying the inner layers of nail polish application by evaporating the solvents in these layers. The top coats are non-toxic and exhibit an unique property of non-yellowing.
