solution have been studied by means of chemicaltristimuluscolorimetry and spectrophotometry. Ionization and hydroxylation constants of the dyes have been determined using chromaticity functions of specific and CIE color difference. It has been shown that aggregation processes in the solution of 4-hydroxystyryl dyes can be observed by means of tristimuluscolorimetry. A scheme of acid-base transformations
The present invention relates to an agent for dyeing keratin fibers, containing at least one compound with a nucleophilic reaction center, at least one alcohol from the group comprising aryl alcohol derivatives and benzyl alcohol derivatives and at least one suitable oxidizing enzyme, as well as to a method for dyeing keratin fibers using this agent.
