Abstract
The present disclosure relates generally to compositions for nail coatings, and particularly, but not by way of limitation, to polymerizable compositions. The disclosure further relates to methods of making a polymerizable, protective and scratch resistant topcoat layer that can be easily removed.
Claims26
A multilayer nail covering system comprising at least a first layer and a second layer,
- wherein at least one of the first and second layer is curable to an acrylic thermoset lattice layer covering a nail surface upon exposure to actinic radiation;
- wherein at least one of the first or second layer comprises:
- hydroxypropyl methacrylate (HPMA),
- at least one reactive urethane (meth)acrylate, and
- a sufficient amount of a non-reactive, solvent-dissolvable polymer and a non-reactive solvent such that, when cured to the nail surface, the system is removable from the nail surface within 20 minutes of exposure to organic solvent.

A nail covering system comprising:
- a basecoat layer;
- an intermediate layer;
- and a topcoat layer;
- wherein at least one layer comprises:
- (a) hydroxypropyl methacrylate (HPMA);
- (b) at least one reactive urethane (meth)acrylate;
- (c) at least one non-reactive, solvent-dissolvable polymer;
- and
- (d) at least one non-reactive solvent;
- and
- wherein, upon exposure to actinic radiation, the at least one layer cures to an acrylic thermoset lattice layer covering a nail surface.
