摘要:
The invention relates to an agent for coloring fibers (A), which is produced by mixing two components (A1) and (A2). Said agent is characterized in that component (A1) contains at least a 2-benzothiazolinone-hydrazone derivative of formula (I) or the physiologically acceptable salt thereof and component (A2) contains at least one ortho-quinone of formula (II) or a para-quinone of formula (III). The invention also relates to a method for dyeing hair using said agent and a multicomponent kit for hair dyeing.

The invention relates to 4-(pyrazol-4-ylimino)-2,5-cyclohexadienylidene ammonium salts of general formula (I) as well as to dyestuff for keratin fibres, containing said compounds.
摘要:
The invention relates to an agent for coloring fibers (A). Said agent is obtained by mixing before use a component A1 containing at least one enamine of formula (I) with a component A2 containing at least one carbonyl compound. The invention further relates to a multiple-component kit for coloring and subsequently decoloring fibers. Said kit consists of colorant A and a component B containing a sulfite. The invention also relates to a method for the temporary coloration of hair.
