Description

EXAMPLES

(1) The present invention will now be illustrated using the following example.

(2) A colored photocrosslinkable composition according to the invention (composition No. 1) is applied onto nails. After drying for approximately 10 minutes, the nail coated with the photocrosslinkable composition is then crosslinked for 60 seconds under an OPI GelColor lamp from OPI (wavelength: 404 nm).

(3) Composition No. 1 (ratio (P1+P2)/P3=2 with 59% ethyl acetate)

(4) TABLE-US-00001 Isophorone Urethane Dimethacrylate 13.5% (X-851-1066-ESSTECH, Inc.) PEG 400 Extended Urethane Dimethacrylate 9% (X-726-0000-ESSTECH, Inc.) Nitrocellulose with 30% isopropyl alcohol (viscosity: E22-1/2s) 16% Ethyl acetate 59% Red 7 lacquer 0.5% (Sunchroma D&C red 7-Sun) Ethyl-2,4,6-Trimethylbenzoylphenylphosphinate 2% photoinitiator (Lucirin TPO-L-BASF)

(5) Nitrocellulose, ethyl acetate and pigment are introduced into a container and placed under stirring with a Rayneri laboratory mixer until a homogeneous mixture is obtained. An aluminum foil will have been previously positioned on the top of the container to prevent the solvents from evaporating. The mixture is then introduced into a Dyno-mill type laboratory bead mill so as to obtain a homogeneous color.

(6) The mixture obtained is then introduced into a light-opaque bottle. The Ethyl-2,4,6-Trimethylbenzoylphenylphosphinate photoinitiator is then introduced into the opaque bottle and mixed using a bar magnet for 1 hour. The Isophorone Urethane Dimethacrylate and PEG 400 Extended Urethane Dimethacrylate compounds are then introduced into the opaque bottle. The mixture obtained is then placed under stirring using a bar magnet for 1 hour.

(7) The surface of the crosslinked coat is not tacky and does not need to be cleaned with isopropanol.

(8) Optionally, the coat may be coated with a finishing layer, with ESSIE Good to go composition.
