         8 . A nail enamel, comprising: butylphthalimide isopropylphthalimide; a secondary film forming polymer; nitrocellulose; and a polyester resin.  
     
     
         9 . A colored nail enamel, consisting essentially of butylphthalimide isopropylphthalimide in a concentration of about 1 to 10 percent by weight; ethyl acetate in a concentration of about 37 to 39 percent weight; butyl acetate in a concentration of about 19 to 26 percent weight; nitrocellulose in a concentration of about 11 to 14 percent weight; isopropyl alcohol in a concentration of about 5 to 6 percent by weight; optionally, polyester resin in a concentration of about 12 percent by weight; optionally, tosylamide/epoxy resin in a concentration of about 8 to 10 percent by weight; stearalkonium hectorite in a concentration of about 0.5 to 2 percent by weight; optionally, acrylic copolymer in a concentration of about 1.5 percent by weight; and coloring agents in a concentration effective to produce color.  
     
     
         10 . A nail enamel, comprising: a plasticizer and butylphthalimide isopropylphthalimide (BIP) in a concentration effective for imparting to the nail enamel, adhesion, hardness and flexibility that is retained for at least about 7 days, when the nail enamel is applied to a nail.  
     
     
         11 . The nail enamel of  claim 10 , wherein the resin is either a tosylamide/epoxy resin or a polyester resin.  
     
     
         12 . The nail enamel of  claim 10  wherein the nail enamel is substantially free of cracking for at least about 7 days after application to a nail.  
     
     
         13 . The nail enamel of  claim 1  wherein the enamel is substantially free of phthalates.  
     
     
         14 . A colored nail enamel, comprising: ethyl acetate; butyl acetate; nitrocellulose; 
 isopropyl alcohol; tosylamide/epoxy resin; butylphthalimide isopropylphthalimide in a concentration of about 1 to about 10 percent by weight; and coloring agents.
