Composition of dyeing composition for keratin fibers

Technical field

The invention relates to a dye composition for keratin fibers, in particular for human hair, the dyeing medium of which comprises at least one direct cationic dye of the defined formula and characterized in that it additionally comprises a substantive component which is at least one specific cationic or amphoteric polymer.

The invention also relates to methods and compositions for use of the dye composition.

BACKGROUND OF THE INVENTION

Two different techniques are used in hair dyeing.

The first technique is dyeing with a semi-permanent or temporary effect, or direct dyeing, which uses colors that can more or less significantly change the natural color of the hair and preserve it after several washes. For this purpose, spot colors are applied which can be used with or without an oxidizing agent. The oxidizing agent is used to lighten the hair color. The lightening is carried out by applying a ready-to-use mixture of a spot color and an oxidizing agent. The lightening of melanin achieves the desired effect, ie uniform coloring for gray hair or color enhancement for hair with a natural pigment.

The second technique is permanent dyeing or oxidative dyeing. This is done by so-called "oxidizing" dyes, which contain the starting material and the reagent. The starting materials of the oxidative dyes, the so-called "oxidizing bases", are mixtures originally non-dyeing or weakly dyeing, whose dyeing ability only develops directly in the hair in the presence of oxidizing agents added at the time of use and thus after the two have been combined. The formation of these coloring compounds is the result of either oxidative condensation on "oxidizing bases" or oxidative condensation of "oxidizing bases" on dye modifying compounds, commonly called "reagents", which are typically present in the coloring compositions used for oxidative dyeing.

Changes in shades of oxidizing colors and their tinting are achieved by adding spot colors.

Direct cationic dyes for dyeing keratin fibers, especially human hair, include known compounds whose composition and structure are described below; these substances

-2 However, they still do not have the required staining properties, especially in terms of uniform fiber overlap ("unisson") when we say that the color is too selective and in terms of resistance to external influences (light, weather, hair washing).

Extensive investigations in this field by the present inventor have led to the finding that the addition of at least one substantive cationic polymer to at least one prior art cationic dye, whose composition (I) will be defined below, results in such a dyeing composition for keratin fibers, which has good hiding power and leveling ability and higher resistance to various external influences.
