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 dyes), 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.
