Artificial nail composition having improved adhesion property

Abstract

An object of the present invention is to provide an artificial nail composition which can improve adhesion between a natural nail and an artificial nail, and also can suppress exfoliation or detachment. The artificial nail composition comprises: (a) a compound having at least one radical polymerizable unsaturated double bond in the molecule, (b) an acidic phosphorus compound having at least one radical polymerizable unsaturated double bond in the molecule, and (c) a radical polymerization initiator.

       2 . The artificial nail composition according to  claim 1 , comprising:
 (a) 0.1 to 98.5 parts by weight of a compound having at least one radical polymerizable unsaturated double bond in the molecule,   (b) 0.1 to 98.5 parts by weight of an acidic phosphorus compound having at least one radical polymerizable unsaturated double bond in the molecule, and   (c) 0.01 to 10 parts by weight of a radical polymerization initiator.   
   
   
       3 . The artificial nail composition according to  claim 1 , wherein (b) the acidic phosphorus compound having at least one radical polymerizable unsaturated double bond in the molecule has a P—OH bond.
