Abstract

A method for coating human nails in which a basecoat composition comprising a water-soluble or water-swellable polymer dissolved in a solvent is first applied to the nails and allowed to dry. This is followed by the application of a photocurable polymer composition which is then exposed to a light source to cure the coating of photocurable polymer.

Claims

1. A METHOD FOR COATING HUMAN NAILS WITH COMPOSITIONS THAT ARE ADOPTED TO BE READILY REMOVABLE FROM THE NAILS BY SOAKING THE NAILS IN WATER WHICH COMPRISES:

A. APPLYING TO SAID NAILS A LIQUID BASECOAT COMPOSITION CONTAINING A WATER-SOLUBLE OR WATER-SWELLABLE FLEXIBLE FILM FORMING POLYMER;

B. ALLOWING SAID COMPOSITION TO DRY ON SAID NAILS WHEREBY A FILM OF SAID WATER-SOLUBLE OR WATER-SWELLABLE POLYMER IS DEPOSITED ON AND ADHERES TO SAID NAILS;

C. APPLYING TO SAID DRIED FILM OF WATER-SOLUBLE OR WATER-SWELLABLE POLYMER A SECOND LAYER OF LIQUID PHOTOCURABLE NAIL LACQUER COMPOSITION CAPABLE OF BEING POLYMERIZED BY AN ACTINIC LIGHT SOURCE;

AND D. EXPOSING SAID LAYER OF PHOTOCURABLE NAIL LACQUER COMPOSITION TO A SOURCE OF ACTINIC LIGHT FOR A SUFFICIENT PERIOD OF TIME TO CURE SAID NAIL LACQUER COMPOSITION WHEREBY A HARD POLYMERIZED LAYER OF NAIL LACQUER IS OBTAINED WHICH OVERLIES AND ADHERES TO SAID BASECOAT LAYER;

SAID WATER-SOLUBLE OR WATER-SWELLABLE POLYMER BEING A POLYMERIZATION PRODUCT OF ONE OR MORE VINYLIC COMPOUNDS OF THE FORMULA;

2. A method according to claim 1 wherein said water-soluble polymer is soluble in water at least to the extent of 1% by weight.

3. A method according to claim 2 wherein said water-soluble polymer is a copolymer of vinyl pyrrolidone and vinyl acetate.

4. A method according to claim 2 wherein said water-soluble polymer is a copolymer of methyl vinyl ether and maleic anhydride.

5. A method according to claim 2 wherein said water-soluble polymer is a terpolymer of crotonic acid, vinyl acetate and a vinyl ester of a higher fatty acid having from C10-C18 carbons.

6. A method according to claim 1 wherein said liquid photocurable nail lacquer comprises a liquid composition containing a polyene component, a polythiol component and a photocuring rate accelerator.

7. A method according to claim 6 wherein said liquid photocurable nail lacquer composition also contains a surfactant selected from the group consisting of sorbitan sesquioleate, sorbitan dioleate, sorbitan trioleate, pentaerythritol dioleate, pentaerythritol trioleate, glyceryl monooleate, gylceryl dioleate, glyceryl trioleate, polyglycerol ester of oleic acid, alkenyldimethylethyl ammonium bromide, di coco dimethyl ammonium chloride, and quaternary imidazolinium salt.

8. A method according to claim 7 wherein:

a. said polyene component is a terminally unsaturated polyene which comprises the formula;

ti (A-X)m wherein m is an integer of at least 2, wherein X is

9. A method according to claim 8 wherein said liquid photocurable nail lacquer composition additionally contains a photocuring rate accelerator selected from the group consisting of aryl aldehyde, diaryl ketone, alkyl aryl ketone, triaryl phosphine and a blend of carbon tetrahalide with polynuclear aromatic hydrocarbon.

10. A method according to claim 9 wherein said liquid photocurable nail lacquer composition contains from about 0.5% to 1.0% by weight of said surfactant, about 1% to 10% by weight of said photocuring rate accelerator and from about 1% to about 98.5% by weight of a mixture of said polythiol and said polyene, the molar ratio of polythiol to polyene in said mixture being in the range of about .50:

1.0 to 1.5;

1.0.

11. A method according to claim 10 wherein said polyene is

12. A method according to claim 11 wherein said polythiol is pentaerythritol tetrakis ( Beta -mercaptopropionate).

13. A method according to claim 11 wherein said polythiol is tris(2-hydroxyethyl)isocyanurate tris ( Beta -mercaptopropionate).
