Description

The Invention relates to means for oxidative dyeing of keratinous fibers, In particular, human hair, the specific cationic, heterocyclic Compounds containing the use of these compounds for dyeing keratin-containing fibers, and a corresponding method for dyeing keratin-containing fibers, in particular human hair.

For dyeing keratin-containing fibers are generally either direct-acting Dyes or oxidation dyes produced by oxidative coupling one or more developer components with each other or with one or more coupler components arise for use. Coupler and developer components are also known as oxidation dye precursors designated.

When Developer components are usually primary aromatic amines with another, in para or ortho position free or substituted hydroxy or amino group, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and its derivatives used.

Regarding other usual ones Dye components becomes explicit to the series "Dermatology", issued by Ch. Culnan, H. Maibach, Marcel Dekker Inc., New York, Basel, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, ch. 7, pages 248-250 (Direct Dyeing), and Chap. 8, pages 264-267 (oxidation dyes), as well as the "European Inventory of cosmetic raw materials ", 1996, published by the European Commission, available in Diskette form of the Federal Association of German industrial and commercial enterprises for medicines, Health food and personal care products e.V., Mannheim.

With Oxidation dyes can be intense colorations with good fastness properties achieve. Still problematic is a provision of oxidation hair dyes with sufficient fastness properties, especially with very good light, washing and rubbing fastness.

Furthermore can p-phenylenediamine and its derivatives in some individuals, the so-called para-allergic, cause allergic reactions. Therefore, it is always a task dye, especially for the coloring of keratin-containing fibers such as hair, which are not allergenic. Consequently, it is desirable to be oxidative To develop dyes which are not derived from p-phenylenediamine derive and still have excellent dyeing properties.

Surprisingly has now been found that the Compounds according to formula I keratinhaltige fibers oxidatively stain and the resulting colorations have excellent fastness properties. They give colorings with exquisite Brilliance and color depth and lead to shades in the blue to red area. The oxidative coupling obtained dyes are also excellent for use in hair dyes.
