Method of applying self curing artificial nails

A method of coating a human nail comprising:

• (1) applying to the nail a self-curing composition consisting essentially of a mixture of the following ingredients, by weight based on the total weight of the composition:
• (a) from about 5% to about 80% of a polymerizable, cross-linkable monomer selected from the group consisting of 2,2 bis propane, ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, polyethylene glycol dimethacrylate, diallyl fumarate, 2,2 bis (4'-methacryloyl phenyl) propane, 2,2 bis (4'-methacryoylethyloxy-phenyl) propane, diallyl phthalate, butenediol-1,4-dimethacrylate, allyl methacrylate, bis (2-methacryloyl-ethyl)-O-phthalate, bis (2-methacryloyl-ethyl)-m-phthalate, bis (2-methacryloyl-ethyl)-p-phthalate, 2-acryloylethyl-methacrylate and
• (b) a second monomer in an amount to about 45%, that copolymerizes with the first monomer upon self-curing of the composition to form a copolymeric structure that is cross-linked, said second monomer being either tetrahydrofurfuryl acrylate or tetrahydrofurfuryl methacrylate;
• (c) from about 0.2% to about 4.0% of a peroxide-type free radical initiator;
• (d) from about 0.1% to about 8.0% of a tertiary amine-type accelerator, and
• (e) from about 5% to about 55% of a polymeric filler that is at least partially soluble in the composition;
• the composition being formulated and the initiator and accelerator being present in quantities to cause self-curing to occur in situ within about 120 to about 400 seconds after mixing the ingredients and application to a nail, and
• (2) permitting the composition to cure and to harden in situ on the nail.

A method of coating a human nail comprising:

• (1) applying to the nail a flowable composition that comprises by weight based on the total weight of the composition:
• (a) from about 5% to about 80% of a first addition polymerizable, ethylenically unsaturated monomer that can form a cross-linked polymer upon polymerization during self-curing of the composition, which monomer contains in its molecule at least two groups that are capable of being addition polymerized upon contact with a peroxide-type free radical initiator and a tertiary amine-type accelerator, the polymerizable groups being members selected from the group consisting of allyl, acryloyl, methacryloyl, or combinations thereof;
• (b) a second monomer that is monoethylenically unsaturated, in an amount up to about 60%, that copolymerizes with the first monomer upon self-curing of the composition to form a copolymeric structure that is cross-linked, the second monomer being either tetrahydrofurfuryl acrylate or tetrahydrofurfuryl methacrylate;
• (c) a peroxide-type initiator;
• (d) a tertiary amine-type accelerator, and
• (e) from about 5% to about 60% of a polymeric filler that is at least partially soluble in said composition.
