PCT/US2006/004380 shampoos, conditioners, hair serums and touch-up colorants, which are all applied to the hair only after it has been colored. It would be advantageous to provide a hair coloring composition and system that improves color retention properties in the hair at the same time as the hair is being initially colored.

[0006] Another disadvantage of these previous compositions and formulations for hair coloring is that they are difficult to use, in that they drip or bleed when the coloring is being applied to the hair, particularly when heat is applied to the hair. It would be advantageous to provide a hair coloring treatment that does not drip or bleed as it is applied to the hair.

[0007] Accordingly, prior to the development of the present invention, there has been no composition and system for hair coloring which: provided improved color retention properties in hair at the same time as the hair was being initially colored; was capable of improving the vibrancy and shininess of colored hair; reduced dripping or bleeding of the coloring, particularly under heat; and was economical and easy to apply and/or use. Therefore, the art has sought a composition and system for coloring of hair which: improves color retention properties in hair at the same time as the hair is being initially colored; is capable of improving the vibrancy and shininess of colored hair; reduces dripping or bleeding of the coloring, particularly under heat; and is economical and easy to apply and/or use.

SUMMARY OF THE INVENTION

[0008] In accordance with the invention, the foregoing advantages have been achieved through the present composition for use in coloring hair and improving color retention properties in colored hair. The composition of the present invention preferably includes hair dye and a copolymer of isobutylmethacrylate and silicone grafted acrylate in isoparaffin, whereby these components are combined in an aqueous based solution.

[0009] In accordance with another aspect of the invention, the foregoing advantages have also been achieved through the present composition for use in coloring hair and improving color retention properties in colored hair. This composition of the present invention may include hair dye and a copolymer of isobutylmethacrylate and silicone grafted acrylate in isoparaffin, whereby these components are combined in a non-aqueous based solution.

[0010] In accordance with yet another aspect of the invention, the foregoing advantages have also been achieved through the present system for use in coloring hair and improving color retention properties in colored hair. This aspect of the present invention may include the step of applying a hair coloring solution to the hair, whereby the solution includes hair dye and a copolymer of isobutylmethacrylate and silicone grafted acrylate in isoparaffin, and whereby these components are combined in a non-aqueous based solution.

[0011] In accordance with still another aspect of the invention, the foregoing advantages have also been achieved through the present system for use in coloring hair and improving color retention properties in colored hair. This aspect of the present invention may include the step of applying a hair coloring solution to the hair, whereby the solution includes hair dye and a copolymer of isobutylmethacrylate and silicone grafted acrylate in isoparaffin, and whereby these components are combined in an aqueous based solution.

[0012] The composition and system of the present invention, when compared with previously proposed compositions and systems for hair coloring, have the advantages

CA 02596880 2012-02-02 of: improving color retention properties in hair at the same time as the hair is being initially colored; being capable of improving the vibrancy and shininess of colored hair; reducing dripping or bleeding of the coloring, particularly under heat; and being economical and easy to apply and/or use.

[0012A] The invention in one broad aspect pertains to a composition for use in coloring hair and retaining color in colored hair, the composition comprising hair dye, and an isobutylmethacrylate and silicone grafted hydroxypropyl or bishydroxypropyl dimethiconylpropyl acrylate copolymer, whereby the hair dye and copolymer are combined in a non-aqueous based solution.

[0012B] The invention also comprehends a process for coloring hair comprising the steps of providing a hair coloring solution in accordance with one of the compositions noted above, and applying the hair coloring solution to the hair, the solution forming a viscous coating over the strands of hair, thereby trapping the hair dye from the hair coloring solution on the strands of hair with the coating to prevent dripping or bleeding of the hair dye from the hair.

[0013] While the invention will be described in connection with the preferred embodiment, it will be understood that it is not intended to limit the invention to that embodiment. On the contrary, it is intended to cover all alternatives, modifications, and equivalents as may be included within the scope of the invention as defined by the appended claims.

Î&amp;0Î4] Thé present invention involves à hair coloring composition, anti a system ibr using such a composition. The composition includes one of more hair dyes combined with a silicon acrylate copolymer. The system includes the step Of Using the Composition inhair that:&amp;being colored, such that the hair strands srecoated with the silicon acrylate copolymer; The silicon acrylate copolymer forms à film orcoating on the hair strands/ which protects fee hair &amp;om damage by the colorant, improves color retention properties is the hair and reduces bleeding and dripping of the colorant.
