Abstract

The present invention relates to a process for dyeing keratin fibres,in particular human keratin fibres such as the hair,in which the said fibres are treated with one or more cosmetic compositions containing,taken together or separately in the said composition(s), the fo llowing ingredients: a) one or more ortho-dipheno l derivatives, b) one or more manganese salts or one or more zinc salts, c) hydrogen peroxide or one or more systems that generate hydrogen peroxide, d) one or more (bi)carbonates or one or more systems that generate (bi)carbonate(s), and e) one or more basifying agents other than the (bi)carbonate(s), and f) one or more salts chosen from titanium salts and scandium salts; it being understood that the pH of at least one of the compositions comprising at least one of the ingredients a) ,b), c), d), e) and/or f) is alkaline, i.e. greater than 7, and that the composition comprising f) the salt(s) chosen from titanium salts and scandium salts is applied to the keratin fibres as the last step of the dyeing process.

Description

[0001] This application was filed on June 22, 2012 and the title of the invention is "Using at least one catechol, manganese salt or zinc salt, hydrogen peroxide, carbonate (hydrogen) salt, alkaline reagent and titanium or scandium salt A divisional application of the Chinese patent application number 201280031020.4 of the method for dyeing hair. technical field [0002] The present invention relates to a process for the coloring of keratin fibers, in particular human keratin fibers such as hair, wherein said fibers are treated with one or more cosmetic compositions comprising: a) one or more a catechol derivative, b) one or more manganese or zinc salts, c) hydrogen peroxide or one or more systems for generating hydrogen peroxide, d) one or more carbonic acids ( hydrogen) salt or one or more systems for generating one or more carbonate (bi) salts, e) one or more alkalizing agents other than the one or more carbonate (bi) salts and f ) one or more salts selected from titanium ...
