Abstract

The invention relates to nail treatment system comprising at least one basecoat, at least one second coat, and optionally at least one topcoat, wherein the basecoat comprises water and at least one non-UV curable adhesive latex compound, and the second coat comprises at least one photocrosslinkable urethane (meth)acrylate and at least one (meth)acrylate monomer.

Claims

1. A nail treatment system comprising:

(1) at least one basecoat comprising;

water; and

at least one non-UV curable latex; and

(2) at least one second coat comprising;

at least one photocrosslinkable urethane (meth)acrylate compound P1;

at least one photocrosslinkable (meth)acrylate monomer; and

at least one photoinitiator.

2. The nail treatment system of claim 1, wherein the basecoat is non-UV curable composition and the second coat is UV curable composition.

3. The nail treatment system of claim 2, wherein the second coat comprises:

at least one photocrosslinkable urethane (meth)acrylate compound P1 comprising at least one structural unit;

4. The nail treatment system of claim 2, which comprises:

(1) the at least one basecoat comprising;

water;

at least one non-UV curable adhesive latex;

optionally at least one plasticizer;

optionally at least one coalescent;

optionally at least one abrasive agent; and

(2) at least one second coat comprising;

at least one photocrosslinkable urethane (meth)acrylate compound P1 comprising at least one structural unit;

5. The nail treatment system of claim 4 wherein the at least one non-UV curable adhesive latex is at least one aqueous acrylate copolymer dispersion.

6. The nail treatment system of claim 5 wherein the at least one non-UV curable adhesive latex is present in an amount of from about 5% to about 95%, by weight, relative to the total weight of the basecoat.

7. The nail treatment system of claim 6 wherein the water is present in an amount of from about 10% to about 95%, by weight, relative to the total weight of the basecoat.

8. The nail treatment system of claim 7 wherein the at least one basecoat further comprises at least one plasticizer in an amount from about 0.1% to about 25%, by weight, relative to the total weight of the basecoat.

9. The nail treatment system of claim 8 wherein the at least one second coat further comprises at least one photocrosslinkable urethane (meth)acrylate compound P2 in an amount from about 1% to about 80%, by weight, relative to the total weight of the second coat.

10. The nail treatment system of claim 9 wherein the at least one second coat further comprises at least one film-forming polymer P3 in an amount from about 0.2% to about 10%, by weight, relative to the total weight of the second coat.

11. The nail treatment system of claim 1 comprising:

(1) at least one basecoat comprising;

water present in an amount from about 30% to about 90% by weight;

at least one non-UV curable adhesive latex in an amount from about 10% to about 90% by weight;
