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 comprising hydroxyethyl (meth)acrylate at a weight percentage of about 2 wt % to about 10 wt %, hydroxypropyl (meth)acrylate at a weight percentage of about 5 wt % to about 15 wt %, isobornyl (meth)acrylate at a weight percentage of about 2 wt % to about 4 wt % and acrylic acid at a weight percentage of about 0.1 wt % to about 1 wt % wherein the weight percentage of each of the monomers is relative to the total weight of the composition, nitrocellulose at a nitrogen weight percentage of about 10.7 wt % to about 12.3 wt % relative to the total weight of the nitrocellulose, a rapid release linear copolymer of butyl acrylate and a mixture of methyl and ethyl acrylates wherein the molar ratio of butyl acrylate to the mixture of methyl and ethyl acrylate is in a range of about 1:0.8 to about 1:1.5 and the weight average molecular weight of the rapid release linear copolymer is in a range from about 3 kDa to about 20 kDa, a polyethylene glycol chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa a polydispersity of about 2.0 to about 5.0 and a weight percentage in a range of about 11.0 wt % to about 16 wt % relative to the total weight of the composition, 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 comprising hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, isobornyl (meth)acrylate and acrylic acid and which are crosslinked with a polyethylene glycol chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa, a polydispersity of about 2.0 to about 5.0 and wherein the weight percentage of the dicarbamate oligomer is in a range about 22 wt % to about 32 wt % relative to the total weight of the photopolymerized composition, nitrocellulose at a nitrogen weight percentage of about 10.7 wt % to about 12.3 wt % relative to the total weight of the nitrocellulose, a rapid release linear copolymer of, butyl acrylate and a mixture of methyl and ethyl acrylates wherein the molar ratio of butyl acrylate to the methyl and ethyl acrylate mixture is in a range of about 1:0.8 to about 1:1.5 and the weight average molecular weight of the rapid release linear copolymer is in a range from about 3 kDa to about 20 kDa, and one or more plasticizers and a photoinitiator, wherein the nitrocellulose, the crosslinked (meth)acrylate polymer and the rapid release linear copolymer are in a substantially homogeneous single solid phase mixture with each other.
A photopolymerized base coat suitable for covering a nail comprising a photopolymerized composition of a crosslinked (meth)acrylate polymer of multiple (meth)acrylate monomers comprising hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, isobornyl (meth)acrylate and acrylic acid which are crosslinked by a polyethylene glycol chain extended di-(hydroxyethylmethacryloyl) trimethylhexyl dicarbamate oligomer of weight average molecular weight in the range of 10 kDa to 20 kDa, a polydispersity of about 2.0 to about 5.0 and a weight percentage of the dicarbamate oligomer in the range of about 22 wt % to about 32 wt % relative to the total weight of the photopolymerized base coat, nitrocellulose at a nitrogen weight percentage of about 10.7 wt % to about 12.3 wt % relative to the total weight of the nitrocellulose, a rapid release linear copolymer of butyl acrylate and a mixture of methyl and ethyl acrylates wherein the molar ratio of butyl acrylate to the mixture of methyl and ethyl acrylate is in a range of about 1:0.8 to about 1:1.5 and the weight average molecular weight of the rapid release linear copolymer is in a range from about 3 kDa to about 20 kDa, and one or more plasticizers and a photoinitiator, wherein the nitrocellulose, the crosslinked (meth)acrylate polymer and the rapid release linear copolymer are in a substantially homogeneous single solid phase mixture with each other.
