Description

The The invention relates to an agent for coloring keratin-containing Fibers, especially human hair, the special vinyl ether in combination with CH-acidic compounds containing Use of this combination in dyeing agents Keratinhaltigen fibers, for color refreshment or nuance of already dyed keratin fibers and a method for dyeing keratin-containing fibers, in particular human Hair.

to Provision of color-changing cosmetic preparations, in particular for the skin or keratin fibers such as human hair, the expert knows the requirements of the Coloring various dyeing systems.

For permanent, intensive colorations with corresponding fastness properties so-called oxidation colorants are used. Such Colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of Atmospheric oxygen with each other or under coupling with one or more Coupler components from the actual dyes. The oxidation colorants Although distinguished by excellent, long-lasting staining results out. For natural-looking dyeings but usually has a mixture of one larger number of oxidation dye precursors be used; in many cases will continue to be substantive Dyes used for shade.

When Developer components usually become primary aromatic amines with another, in para or ortho position free or substituted hydroxy or amino group, heterocyclic hydrazones, diaminopyrazole derivatives and 2,4,5,6-tetraaminopyrimidine and its derivatives used.

Specific Representatives are, for example, p-phenylenediamine, p-toluenediamine, 2,4,5,6-tetraaminopyrimidine, p-aminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2- (2,5-diaminophenyl) ethanol, 2- (2,5-diaminophenoxy) ethanol, 4-amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 4,5-diamino-1- (2-hydroxyethyl) pyrazole, 2-hydroxy-4,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine, 2,5,6-triamino-4-hydroxypyrimidine and 1,3-N, N'-bis (2-hydroxyethyl) -N, N'-bis (4-aminophenyl) -diaminopropan-2-ol.

When Coupler components are usually m-phenylenediamine derivatives, Naphthols, pyridine derivatives, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols used. Suitable coupler substances in particular 1-naphthol, 1,5-dihydroxynaphthalene, 2,7-dihydroxynaphthalene, 1,7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, Resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 1-phenyl-3-methyl-pyrazol-5-one, 2,4-di-chloro-3-aminophenol, 1,3-bis- (2,4-diaminophenoxy) -propane, 2-amino-3-hydroxypyridine, 4-chlororesorcinol, 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol and 2-methyl-4-chloro-5-aminophenol.

For temporary stains become common Dyeing or toning agents used as coloring Component so-called direct pullers included. This is it around dye molecules that are directly on the substrate raise and no oxidative process to form the Need color. Belongs to these dyes for example, that already from antiquity for coloring body and hair known henna. These dyes are much more sensitive to shampooing than the oxidative dyeings, so that then very much faster a much undesirable nuance shift or even a visible homogeneous color loss occurs.

After all another dyeing process has received a lot of attention found. In this process, precursors of the natural Hair Dye Melanin on the substrate, eg. As hair applied; These then form natural analogues in the course of oxidative processes in the hair Dyes off. At, in particular multiple, application of means With 5,6-dihydroxyindoline it is possible to give people with graying Hair to reproduce the natural hair color. The coloration can be done with atmospheric oxygen as the sole oxidant, so that resorted to no further oxidizing agents must become. In persons with originally mittelblondem to brown hair, indoline can be the sole dye precursor be used. For use with persons with original red and especially dark to black hair color can against it Satisfactory results often only through co-use further dye components, in particular special oxidation dye precursors, be achieved.

Another possibility for color change is the use of colorants containing so-called Oxofarbstoffvorprodukte. A first class of oxo dye precursors are compounds with at least one reactive carbonyl group. A second class of oxo dye precursors form CH-acidic compounds and compounds having primary or secondary amino groups or hydroxy groups, which in turn are selected from compounds of the group formed from primary or secondary aromatic amines, nitrogen-containing heterocyclic compounds and aromatic hydroxy compounds. The aforesaid classes are generally not themselves dyes, and therefore are not in themselves suitable for coloring keratinous fibers alone. In combination, they form dyes in a non-oxidative process of so-called oxo dyeing. The resulting dyeings have partially color fastness on the keratin-containing fiber, which are comparable to those of the oxidation dyeing.

The Nuance spectrum achievable with gentle oxo staining is very broad, and the color obtained often shows an acceptable brilliance and color depth. Above mentioned compounds However, second classes can also contain corresponding oxidation dye precursors of the developer and / or coupler type with or without use of a Oxidizing agent find use. Thus leaves The method of oxo-staining is readily compatible with the oxidative Combine dyeing system.

The existing staining technology of oxo staining In many cases it is possible to dye the hair intensively, However, at the same time it also has a number of disadvantages, in particular: in improvement fastness properties such as wash fastness and light fastness are. Object of the present invention is it therefore, to provide hair dyeing agents, which on the hair even without the use of oxidizing agents intensive colorations with good dyeing properties to generate. In particular, the generation of intensive Dyeing with good light fastness and good, pH-stable wash fastness represents the task. Surprisingly, it was found that a combination of special vinyl ethers and CH-acidic Compounds satisfies these conditions satisfactorily.

dye, containing vinyl ether compounds according to the following Formula I in combination with CH-acidic compounds, as well as the use this combination for dyeing keratinous fibers or for color refreshing or nuancing already dyed keratin-containing fibers are not yet known.

Surprisingly could now be found that with the use at least one specific vinyl ether compounds according to the following Formula (I) in combination with at least one CH-acidic compound Only two components are necessary to intense, long-lasting To achieve shades on the hair.
