Abstract (en)

[origin: DE10130144A1] The invention relates to an agent for colouring fibres, said agent being obtained by mixing two components if necessary, by adding an alkalisation agent or an acid. Said agent is characterised in that one of the components (component A2) contains at least one electrophilic compound and the other component (component A1) contains at least one 1-benzopyrane of formula (Ia)/(Ib) or one 1-benzopyrylium-derivative of formula (I). The invention also relates to a method for the temporary colouration of keratin fibres, whereby hair is initially coloured with the above-mentioned known colouring agent and then discoloured by a reducing agent at any later given moment.
