Abstract
Photopolymerizable topcoat and color coat gel compositions suitable for forming a photopolymerized nail coating are described. Both gel compositions include a mixture of one or more pre-formed polymers, a (meth)acrylic monomer, a multi-(meth)acrylate crosslinker, a UV photoinitiator and an antioxidant. The color coat gel composition includes pigments, a smectite clay and silica.
Claims5
A topcoat composition consisting of:
- a single phase mixture of a preformed crosslinked polyester of C5-C12 alkyl-dicarboxylic acid, a C2-C10 diol and an aromatic or alkyl tricarboxylic acid or anhydride thereof, a (meth)acrylate monomer of di-C1-C3 alkylamino C1-C3 alkyl methacrylate, a multi-(meth)acrylate crosslinker of trimethylolpropane triacrylate or tetramethylol methane tetraacrylate, a UV photoinitiator and an antioxidant, wherein;
- the preformed crosslinked polyester concentration is about 40 wt. % to about 44 wt. %,
- the (meth)acrylate monomer concentration is about 35 wt. % to about 45 wt. %,
- the cross-linker concentration is about 14 wt. % to about 17 wt. %,
- the weight ratio of the weight amount of the preformed crosslinked polyester to the weight amount of the combination of monomer and crosslinker is in a range of about 0.5:1 to about 1.1:1,
- the (meth)acrylate monomer is a solvent for and solubilizes the preformed crosslinked polyester,
- the preformed crosslinked polyester is soluble in organic solvent, and
- the topcoat composition is a homogeneous, clear, stable, single phase mixture, does not separate into individual components, is essentially free of organic solvent and aqueous medium, and optionally includes one or more of a free radical scavenger, a polymerization regulator, a plasticizer, a surfactant and an emulsifier.
