Description

[Technical field]

[0001] The present invention relates to compositions for dyeing keratinous fibers with oxidative and direct dyes. Additionally, two- or three-part compositions, kits of parts and dyeing methods are disclosed. [Background technology]

[0002] Direct dyes have been of particular interest to the cosmetics industry over the past decade. Unlike oxidative dyes, direct dyes are easy to apply to keratin fibers but often lack durability on keratin fibers.

[0003] One of the technical challenges for direct dyes in general is their poor durability on keratin fibers that have been previously damaged by environmental factors or chemical treatments such as perms or bleaching. Chemical treatments change the internal structure of the hair, usually improving dye uptake compared to untreated hair, but at the same time can make the direct dyes more easily washed out. Thus, consumers who have previously chemically treated their hair may experience poor durability of the direct dyes, especially after several hair washes. Furthermore, the color intensity may weaken after several washes, and the hair may further experience undesirable color shifts depending on the different bleeding rates of the individual direct dyes.

[0004] In the daily work of a beauty salon, it is not always easy for an expert to analyze a client's previous hair damage, since some of the previous treatments may have already been washed off and their effects are no longer visible. Even if the hair is assumed to be healthy and then directly dyed, it may come as a surprise to the hairdresser and the client that the durability of the dyeing treatment is exceptionally low. Such an experience is sure to be disappointing for all parties involved.

[0005] DE202005002552 discloses 1,4-diamino-2-methoxymethyl-benzene, oxidation dye couplers, and certain direct dyes to address skin compatibility and dyeing issues.

[0006] FR3026004 (Patent Document 2) discloses 1,4-diamino-2-methoxymethyl-benzene oxidation dye couplers and cationic direct dyes to address the dyeing strength problem. [Prior art documents] [Patent documents]
