A composition for dyeing keratin fibers, the at least one free-radical connection from the nitroxyl - type and at least one primary or secondary alcohol

摘要

Dye composition for the oxidation dyeing of keratin fibers, which, in a suitable medium for the dyeing:– at least one free-radical connection from the nitroxyl - type, which is connected as an oxidation and– at least one primary or secondary alcohol of the formula (i), (ii) or (iii) and / or at least one of the addition salts thereof, wherein:– A₁ and a₂, which can be identical or different, an aliphatic chain having 2 to 50 carbon atoms, which optionally contains one or more hetero atoms, which, under nitrogen, sulfur, oxygen and phosphorus are selected,– where a₁ and a₂ together form:– an unsaturated, aromatic or non-aromatic, condensed or mono not condensed carbocyclic cyclic or poly carbonyl cyclic group having 6 to 50 carbon atoms,– an aromatic or non-aromatic, condensed or not condensed, 5 - to 30 - member in question mono heterocyclic, or poly heterocyclic group, the one or more hetero atoms, which, under nitrogen, sulfur, oxygen and phosphorus are selected,– these chains or rings with the optionally..
