ABSTRACT There is provided a composition readily applicable to human nails for cosmetic, protective and other purposes, and which polymerizes upon exposure to ultraviolet radia- tion. The composition is used to produce artificial nails by direct application to human nail tissue and if cured by exposure to a controlled source of radiation. The composition consists essentially of from about 40% to about 90% by weight of the composition of a monofunctional ester monomer selected from the group consisting of esters of acrylic acid and 1-4 carbon alkyl-substituted acrylic acids with methyl, ethyl, propyl, isopropyl, butyl, isobutyl, furfuryl, tetrahydrofurfuryl and glycidyl alcohols and mixtures of such esters; from about 3% to about 40% by weight of a composition of an ester momomer selected from the group con- sisting of esters of acrylic acid and 1-4 carbon alkyl- substituted acrylic acids with polyhydric alcohols containing 2 to 4 hydroxyl groups and mixtures of such esters; from about 0.1% to about 30% by weight of the composition of an initiator that acts upon exposure to ultraviolet radiation to initiate polymerization; and from about 5% to about 25% by weight of the composition of a modifier that is soluble or swellable in the admixture and is selected from the group consisting of particulate cured elastomers up to 300 microns in particle size, and mixtures of such elastomers with a particulate cellulose ester or a particulate cellulose ether-ester having up to 300 micron particle size in the ratio of at least 4.5 parts by weight of the former to each one part by weight of the latter. The composition is characterized in that the composition after curing exhibits an in vivo adhesion to natural human nails of at least about 25 pounds per square inch, a flexural modulus of elasticity of at least 50 x 103 pounds/ square inch, a flexural strength of at least 3000 pounds/square inch, and an elongation to break under flexural stress of at least 3.5% as measured under ambient pressure and temperature conditions.
