TITLE OF THE INVENTION

COMPOSITIONS CONTAINING TEMPERATURE SENSITIVE COLORANT

FIELD OF THE INVENTION

[0001]    The present invention generally relates to compositions comprising temperature sensitive colorant as well as to methods of applying such compositions to keratin materials and kits comprising such compositions.  Such compositions possess improved properties and characteristics such as, for example, allowing the color or shade of a composition to be changed or altered before, during or after application, and/or enhancing the characteristics, appearance or properties of other colorants in the same composition or in a complementary composition.    

BACKGROUND OF THE INVENTION    

[0002]    Cosmetic compositions often contain colorant to provide a coloring effect to the keratin material to which they have been applied.  In the past, changing the coloring effect provided by these compositions has been difficult if not impossible.  Generally speaking, the only way to change coloring was to apply a different composition having a different colorant over the previously applied composition, or to remove the applied cosmetic composition, replacing it with a different composition containing a different colorant.  Obviously, such additional steps and manipulations were time-consuming and/or inconvenient, and inhibited changing the desired coloring effect.   Thus, there is a need for improved colorant-containing compositions in which at least some of the colorant components can more easily be changed or altered before, during or after application by the end user.

[0003]    Accordingly, one aspect of the present invention is a care and/or makeup and/or treatment composition for keratin materials which is able to address or overcome the aforementioned problems with the prior art compositions.

BRIEF SUMMARY OF THE INVENTION

[0004]    The present invention relates to compositions comprising at least one temperature sensitive colorant.  Such a composition could be, for example, a topcoat (for example, a mascara, foundation or lipstick) which could be applied to a basecoat (for example, a primer), or a basecoat (for example, a mascara, foundation or lipstick) upon which a topcoat (for example, a gloss or moisturizing composition) could be applied.  

[0005]    The present invention further relates to methods of applying a composition comprising at least one temperature sensitive colorant to a keratin material . 

[0006]    The present invention also relates to methods of applying to a keratin material a basecoat composition comprising at least one temperature sensitive colorant, and then applying to the basecoat composition a topcoat composition.

[0007]    The present invention also relates to methods of applying to a keratin material a basecoat composition, and then applying to the basecoat composition a topcoat composition comprising at least one  temperature sensitive colorant.
