         2 . A radiation curable gel nail coating composition according to  claim 1 , further comprising from about 3% to about 6% by weight of one or more methacrylic acid alkylene diol esters, said % by weight of each of the one or more esters being based on the weight of the nail coating composition. 
     
     
         3 . A radiation curable gel nail coating composition according to  claim 1 , wherein the one or more methacrylic acid alkylene diol esters are each selected independently from hydroxyethyl methacrylate and hydroxypropyl methacrylate.

         8 . A radiation curable gel nail coating composition according to  claim 1 , wherein the solvent is selected from the group consisting of esters, ketones, alcohols, alkanes, aromatics, amides and mixtures thereof. 
     
     
         9 . A radiation curable gel nail coating composition according to  claim 1 , wherein the solvent is selected from the group consisting of esters, ketones, alcohols, alkanes, aromatics, and mixtures thereof. 
     
     
         10 . A radiation curable gel nail coating composition according to  claim 1 , wherein the solvent is selected from butyl acetate, ethyl acetate, propyl acetate, ethanol, isopropyl alcohol, butyl alcohol, amyl acetate, acetone, and diacetone alcohol, or mixtures thereof. 
     
     
         11 . A radiation curable gel nail coating composition according to  claim 1 , wherein the solvent is present at a range of from about 15% to about 40% by weight of the nail coating composition. 
     
     
         12 . A radiation curable gel nail coating composition according to  claim 1 , further comprising at least one photoinitiator. 
     
     
         13 . A radiation curable gel nail coating composition according to  claim 12 , wherein the at least one photoinitiator I present in a range of from about 0.1% to about 1% by weight of a photoinitiator based on the weight of the nail coating composition. 
     
     
         14 . A radiation curable gel nail coating composition according to  claim 12 , wherein the at least one photoinitiator is selected from hydroxycyclohexyl phenyl ketone, benzophenone, and mixtures thereof. 
     
     
         15 . A radiation curable gel nail coating composition according to  claim 1 , wherein at least one methacrylic acid ester is isobornyl methacrylate. 
     
     
         16 . A radiation curable gel nail coating composition according to  claim 1 , further comprising a cross linking agent. 
     
     
         17 . A radiation curable gel nail coating composition according to  claim 16 , wherein the cross linking agent comprises esters of methacrylic acid and a polyhydroxy compound, each of said hydroxyl groups esterified with methacrylate. 
     
     
         18 . A radiation curable gel nail coating composition according to  claim 17 , wherein the cross linking agent comprises trimethylolpropane trimethyacrylate. 
     
     
         19 . A kit suitable for coating mammalian nails with a radiation curable gel nail coating composition, comprising:
 a radiation curable gel nail coating composition according to  claim 5 ; and   a bottle designed to substantially exclude the passage of UV light.   
     
     
         20 . A kit according to  claim 19 , wherein the bottle comprises clear glass coated with a finish to substantially exclude UV light transmission through the glass. 
     
     
         21 . A kit according to  claim 19 , further comprising a brush for applying the radiation curable gel nail coating composition.
