摘要:
The invention relates to 1,3-dihydroxybenzene derivatives of general formula (I) or (Ia), or the physiologically acceptable, water-soluble salts thereof, R'1 representing a substituted pyridyl group, a pyrimidyl group, or a radical of formula (IIa) or (IIIa). The invention also relates to colorants containing said compounds and used on keratin fibres.
摘要:
Pro-dyes of direct dyes having an enzymatically-labile functionality, e.g. glutaramide derivatives of direct dyes of formula (I) or their physiologically acceptable salts, are described, as well as compositions for dyeing keratinous fibers containing these pro-dyes, as well as compositions for dyeing keratinous fibers containing a combination of at least one pro-dyes and at least one enzyme capable of cleaving the glutaramide functionality in the pro-dye. A method for dyeing keratinous fibers with the aforementioned dyeing compositions is also described.
摘要:
