Compositions and methods for nail coatings
View Patent ↗The present disclosure relates generally to compositions for natural and artificial nail coatings, and particularly, but not by way of limitation, to polymerizable compositions and adhesion-promoting basecoats polymerized therefrom. The disclosure further relates to methods of making a polymerized basecoat that are more easily removed than artificial nail enhancements and more durable and long lasting than nail polish coatings.
