Abstract
A photopolymerizable composition suitable for forming a polymerized base coat of a substantially uniform mixture of nitrocellulose and crosslinked (meth)acrylate polymer is disclosed. The composition comprises an ethyl acetate solution including multiple (meth)acrylate monomers, nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, a chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight of 10 to 20 kDa, one or more plasticizers and a photoinitiator.

A composition suitable for formation of a photopolymerized base coat on a nail, comprising:
- a mixture of components including multiple (meth)acrylate monomers, nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, a chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa, one or more plasticizers and a photoinitiator wherein the mixture is in an ethyl acetate solution.
A photopolymerized composition comprising a crosslinked (meth)acrylate polymer of multiple (meth)acrylate monomers and chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa, which is in a mixture with nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, one or more plasticizers and a photoinitiator.
A photopolymerized base coat suitable for covering a nail comprising a photopolymerized composition of a crosslinked (meth)acrylate polymer of multiple (meth)acrylate monomers and chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa, which is in a mixture with nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, one or more plasticizers and a photoinitiator.
A method for forming a photopolymerized base coat on a nail comprising the steps of:
- coat a nail with a photopolymerizable composition of a mixture of multiple (meth)acrylate monomers, nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, a chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 13 kDa to 17 kDa, one or more plasticizers and a photoinitiator wherein the mixture is in an ethyl acetate solution, and
- exposing the photopolymerizable composition with UV radiation for a sufficient time to cure the composition and produce the photopolymerized base coat.
A method for removal of a photopolymerized base coat of a crosslinked (meth)acrylate polymer of multiple (meth)acrylate monomers and chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 13 kDa to 17 kDa, which is in a mixture with nitrocellulose, a rapid release copolymer of alkyl acrylate monomers, one or more plasticizers and a photoinitiator, comprising:
- soaking the photopolymerized base coat in an organic solvent to substantially uniformly swell the photopolymerized coat and enable its removal at least as large pieces of swelled coating.
