Description

The The invention relates to novel cationic dyes and compositions for Dyeing and, if necessary, simultaneous lightening of keratin-containing fibers, in particular human hair, these Dyes contain the use of these cationic dyes for dyeing hair and a method for dyeing of keratinous fibers, in particular human hair.

For The coloring of keratinic fibers generally occurs either direct dyes or oxidation dyes, the by oxidative coupling of one or more developer components arise with each other or with one or more coupler components, for use. Coupler and developer components are also known as Oxidation dye precursors referred.

When Developer components usually become primary aromatic amines with another, in para or ortho position free or substituted hydroxy or amino group, Diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone 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, 1-phenyl-3-carboxamido-4-amino-pyrazol-5-one, 4-amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 2-hydroxymethyl-4-aminophenol, 2-hydroxy-4,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine, 2,5,6-triamino-4-hydroxypyrimidine and 4,5-diamino-1- (2-hydroxyethyl) pyrazole.

When Coupler components are usually m-phenylenediamine derivatives, Naphthols, resorcinol and resorcinol derivatives, pyrazolones, m-aminophenols and substituted pyridine derivatives. As coupler substances Particularly suitable are α-naphthol, 1,5-, 2,7- and 1,7-dihydroxy naphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 2,4-diaminophenoxyethanol, 2-amino-4- (2-hydroxyethylamino) -anisole (Lehmann's Blue), 1-phenyl-3-methyl-pyrazol-5-one, 2,4-dichloro-3-aminophenol, 1,3-bis- (2,4-diaminophenoxy) -propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol, 3-amino-6-methoxy-2-methylaminopyridine and 3,5-diamino-2,6-dimethoxypyridine.

Although intensive dyeings with good fastness properties can be obtained with oxidation dyes, the development of the color is generally carried out under the influence of oxidizing agents such. H ₂ O ₂ , which in some cases may result in damage to the fiber. Furthermore, some oxidation dye precursors or certain mixtures of oxidation dye precursors can sometimes sensitize people with sensitive skin. Direct dyes are applied under more gentle conditions, but their disadvantage is that the dyes often have only insufficient fastness properties, especially in hair washing, but also against external influences, such as sunlight or reactive environmental chemicals, such as swimming pool water.

One special challenge for hair coloring with direct dyes provides the uniform Coloring of frequently pretreated hair, such as bleached or permed hair, in which the fiber is in different lengths or differently treated areas has a very different degree of predilection. During the dyeing itself, the dye can on differently pre-damaged hair an uneven Dyeing behavior, but also by repeated shampooing Can the dyes in the different hair areas be washed out differently, creating a non-uniform and thus undesirable color result is achieved. at Hair dyes, which is a uniform Achieve color result on different pre-damaged hair, the expert speaks of a good leveling ability.

The object of the present invention is to provide colorants for keratinic fibers, in particular human hair, which are at least equivalent in terms of color depth and fastness properties, such as lightfastness, rubfastness and washfastness, as well as perspiration and cold wave fastness, to the usual oxidation hair colorants However, necessarily on oxidizing agents such. B. H ₂ O ₂ instructed to be. In particular, the colorants should have a good wash fastness. Finally, it is particularly desirable to provide colorants with good leveling power.

In addition, the most luminous and intense colors possible, preferably in the fashionable Ge particularly interesting red and orange areas are achieved.

In the case of simultaneous use with oxidation dyes direct drawers should have sufficient stability against H ₂ O ₂ and not lose their positive fastness and dyeing properties. In addition, the colorants must have no or only a very low sensitizing potential and may under no circumstances be mutagenic.

It was surprisingly found that compounds of general formula (I) are very good as substantive dyes suitable for hair coloring. In dyeings become extremely intense shades, especially in orange and Red area, with very good fastness properties, especially very good wash fastness, received. Furthermore, the achieved Dyeings by an excellent leveling process.

The substantive dyes also deliver at the same time Application of oxidizing agents such as hydrogen peroxide or a Mixture of hydrogen peroxide and peroxodisulfates luminous nuances without attenuation of color intensity and color brilliance. In this way, the simultaneous lightening and coloring of hair possible, whereby even on dark hair one bright coloring can be achieved.

dye, containing compounds according to the following formula (I) as well as some of the corresponding compounds themselves are so far not known.

  with the proviso that X stands for a physiologically acceptable anion.

In principle, as anion X ^- any physiologically acceptable anion can be used. This includes both anions derived from mineral acids, anions derived from organic acids, and inorganic anions.

Examples for mineral acids are carbonic acid, hydrochloric acid, Hydrofluoric acid, perchloric acid, sulfuric acid, phosphoric acid, Phosphoric acid or nitric acid.

Examples for organic acids are formic acid, Acetic acid, tartaric acid, citric acid, Lactic acid, benzoic acid, salicylic acid, Glycolic acid, malic acid or organic sulfonic acids and sulfuric acid esters.

Examples Anorgic anions are halides such as fluoride, chloride, Bromide or iodide, hexafluorophosphate, tetrachlorozincate, hexachloroferrate or tetrachloroaluminate.

It will be understood by those skilled in the art that with polyvalent anions derived from acids having more than one deprotonatable hydrogen atom, the stoichiometric ratios within the salt must be considered and adjusted. For example, with a salt of the divalent sulfate anion, it is understood that two monovalent organic cations are needed to balance the charge within the salt. For the sake of simplicity, however, in this application the polyvalent anion is provided with a corresponding stoichiometric coefficient, so that a negative net Charge the anion of -1 results. Examples of this notation are ½ sulfate or 1/3 citrate.

A another preferred embodiment of the present invention are means for dyeing and possibly simultaneous Lightening keratinic fibers, which is a compound according to formula (I), wherein the physiologically acceptable anion X is an anion which is selected from the group formed by chloride, bromide, iodide, fluoride, Perchlorate, hydrogen sulfate, ½ sulfate, ½ tetrachlorozincate, p-benzenesulfonate, p-toluenesulfonate, acetate, tetrafluoroborate, trifluoromethanesulfonate, Hexafluorophosphate, methanesulfate or methanesulfonate.

2.4 Wash fastness and leveling ability

2.4.1. Production of leveling strands

It were about 15 cm long, 80% gray hair strands of Company Kerling used. The lower part of the strand was for 30 minutes a cold wave and then subjected to fixation for 10 minutes. After washing and drying became the lower stratum part for Ultra-blonded for 30 minutes, washed and dried. Then it became the lower part of the hair strand again after the above Procedure cold-waved and fixed. Subsequently, the entire strand subjected to ultrablonding, washed and dried again. The treated hair strands show a strong degree of damage in the lower part of the Streak and moderate damage in the upper Part of the strand on.

2.4.2. colorations

Each 8.0 g of the nonionic staining cream (staining cream 2.1.1), containing as inventive, substantive Dye either 4- [7- (diethylamino) -2-oxo-2H-chromen-3-yl] -1-methylpyridinium p-toluenesulfonate or 1-allyl-4- [7- (diethylamino) -2-oxo-2H-chromen-3-yl] pyridinium bromide, were applied to a leveling bar and there for Leave at 30 ° C for 30 minutes. After completion of the exposure time the hair was rinsed out and then dried.

2.4.3. Measurement of washfastness and leveling ability

To the dyeing process, the Egalisiersträhnen colorimetric with a colorimeter from Datacolor, Type Spectraflash 450 measured. One measurement took place in the upper one Part of the strand of hair, another measurement was in the lower, severely damaged part of the tress performed. Here, the L value stands for the brightness (the lower the L value is, the greater the color intensity), while the a-value is a measure of the red component of a color (i.e., the larger the a value is, the greater the proportion of red). The b-value is a Measure of the blue component of the color, with the blue component the greater the more negative the b-value is.

Then the tresses were 6 times by hand with a 25% Texapon ^® NSO-UP solution (sodium lauryl ether sulfate, ethoxylated with 2 EO; INCI name: Sodium Laureth Sulfate, from Cognis, Germany) and dried after every wash with a Hair dryer dried. After the last drying, a new colorimetric measurement was carried out according to the procedure described above.

Table 3 and 4 show the results obtained for the two dyeing creams each containing the substantive dyes of the invention. Table 3. 4- [7- (Diethylamino) -2-oxo-2H-chromen-3-yl] -1-methylpyridinium p-toluenesulfonate (DZ1) upper part of the strands lower part of the stretcher L a b L a b before the wash 37.65 44.66 37.21 30.72 43.59 26,86 after the wash 48.34 42.21 53.14 50,30 43.33 56,00 Table 4. 1-Allyl-4- [7- (diethylamino) -2-oxo-2H-chromen-3-yl] pyridinium bromide (DZ2) upper part of the strands lower part of the stretcher L a b L a b before the wash 32.05 38.84 26.44 27.02 37.57 20.18 after the wash 43.54 45.65 44.29 42.46 46,00 41.25

A good leveling ability exists when the Lab values measured in the upper part of the strands and in the lower part of the strands show only slight deviations from one another. Both for the staining cream containing 4- [7- (diethylamino) -2-oxo-2H-chromen-3-yl] -1-methylpyridinium p-toluenesulfonate (DZ1) and for the staining cream containing 1-allyl-4- [ 7- (diethylamino) -2-oxo-2H-chromen-3-yl] pyridinium bromide (DZ2), the L values, the a values and the b values of the upper part of the strands differ only slightly from those of the lower strand part from. This applies to both substantive dyes both for the pre-wash and especially post-wash values. The leveling power of both substantive dyes is for this reason to classify as very good.

A good washfastness is present when received before the washout L values, a values and b values are only marginally different from those after differ from the values obtained during the wash-out process. This too is for both substantive dyes of the case, so that the wash fastness Of the two substances is also classified as very good.
