Description

Cationic azacyanine dyes and colorants containing them

The present invention relates to cationic azacyanine dyes containing agents for dyeing fibers, such as keratinic fibers, wool, silk or furs, and in particular human hair, as well as novel azacyanine dyes.

Cationic substantive dyes have long been known in hair tints. In oxidative dyeing systems, which simultaneously lighten the natural hair melanin during the dyeing process, especially nitro and azo dyes are used, since most other dye types do not survive the oxidation process.

From JP-OS 07-126543 it is known to use certain azacyanines for the surface treatment of optical recording media.

Surprisingly, it has now been found that certain cationic azacyanine dyes allow dyeings into the blue and blue-green range and, depending on the substitution pattern, are stable to oxidation and thus can also be used in oxidative dyeing systems.

The symmetrical azacyanines in which the two ring systems attached to the N atom are identical (for example azacyanines of the formula (II)) can be prepared by the method of F. W. Kröck and F. Kröhnke, Chem. Ber. 104, 1645-1654 (1971). This is based on an aromatic nitrogen compound which carries in 2- position an alpha-keto alkyl chain, z. For example, 2-acetylpyridine, which is reacted in synthesis stage 1 under alkaline conditions with an aromatic aldehyde and then in a second stage in the presence of ammonium acetate / glacial acetic coupling with itself to the dye. Unsymmetrical dyes (ie compounds of the formula (I) in which the two ring systems attached to the N atom are not identical, for example the following compounds of the formula (III) to (VII)) are reacted in the second stage by reaction with a primary Amine (without addition of an ammonium compound), or with the addition of an ammonium compound with a ketone or aldehyde prepared.

Symmetrical dyes of the invention may, for example, have the following mesomeric basic structure (II),

(H)

where the radicals R 2, R 2 ', R 3 and R 3' have the abovementioned meaning (with R 2 - R 2 ', R 3 = R 3'), X 'and X are identical and hydrogen, an alkyl group, an alkoxy group, an alkoxyalkyl group, represents a hydroxy group, a hydroxyalkyl group, an alkylcarboxylic acid amide group, a dialkylamino group, a carboxylic acid ester group, an alkylcarboxylic ester group, a carboxylic acid group, an alkylcarboxylic acid group, a sulfonic acid group, an alkylsulfonic acid group or a halogenator, and Y is a counterion selected from the group of organic or inorganic acid anions , such as As halides (chloride, bromide, iodine id), sulfates, acetates, lactates, perchlorate or hexafluorophosphate means. (In the following text only the left of the two mesomeric structures is used for illustration).

With R 2 = R 2 '= R 3 = R 3' = H, X = X '= 4-methoxy and Y = acetate, for example, a dyestuff (IIa) is obtained which is absorbed by bleached hair of deep blue color. Depending on the substitution pattern of the dyes, dyeings are also possible in the presence of hydrogen peroxide / alkalizing agent and even persulfates.

In the asymmetric Azacyaninen, such as. B. the dye (III) or (IV) is added in the second stage instead of ammonium an aromatic amine. With 4,5-diamine-pyrazoles as reactants, bright shades in the violet range result.

(III) (IV)

With R1 '= 4-methoxyphenyl, R3' = hydrogen and Y = acetate gives an intense violet-red dye. Compound (III) is practically not and compound (IV) is only partially resistant to hydrogen peroxide / alkalizing agent. An altered substitution pattern on the nitrogen in the 5-position of the pyrazole increases the peroxide stability significantly.

(V) (VI)

With R1 '= 4-methoxyphenyl, R3' = hydrogen and Y = acetate gives bright violet-red dyes, the dye (V) is largely resistant and the dye (VI) is very resistant to hydrogen peroxide / alkalizing.

If a pyrazolin-5-one-amine is used as coupling partner in the second synthesis stage, z. B. with 4-aminoantipyrine a bright red dye (R1 '= 4-methoxyphenyl, R3' = hydrogen and Y = acetate) of the formula (VII).

However, the particularly preferred preparation forms are a cream, a gel, an emulsion or a powder or granule preparation. Their composition is a mixture of the dyes with the usual additives for such preparations.

Typical additives in solutions, creams, emulsions, gels, powders or granules are, for example, solvents such as water, lower aliphatic alcohols, for example ethanol, propanol or isopropanol, glycerol or glycols such as 1, 2-propylene glycol, wetting agents or emulsifiers from the classes of anionic, cationic, amphoteric or non-ionic surface-active substances, for example fatty alcohol sulfates, ethoxylated fatty alcohol sulfates, alkyl sulfonates, alkylbenzenesulfonates, alkyltrimethylammonium salts, alkylbetaines, ethoxylated fatty alcohols, ethoxylated nonylphenols, fatty acid alkanolamides and ethoxylated fatty acid esters, furthermore thickeners such as higher fatty alcohols, starch, cellulose derivatives, petrolatum, paraffin oil, sugars and fatty acids, and also care substances such as cationic resins, cationic, nonionic, anionic and amphoteric polymers, lanolin derivatives, Cholesterol, pantothenic acid and betaine. The constituents mentioned are used in the amounts customary for such purposes, for example the wetting agents and emulsifiers in concentrations of about 0.1 to 30 percent by weight, the thickeners in an amount of about 0.1 to 30 percent by weight and the conditioners in one Concentration of about 0.1 to 5.0 percent by weight.

In addition, the dyeing agent may contain other conventional additives, for example antioxidants such as ascorbic acid, thioglycolic acid or sodium sulfite, as well as perfume oils, penetrating agents, buffer systems, complexing agents, preservatives, wetting agents, emulsifiers, thickeners, encapsulating agents, granulation aids and conditioners.

The ready-to-use colorant according to the invention can be used undiluted or can be prepared immediately before use by mixing the color carrier mass containing the dyes with water, a care product or with an oxidizing agent.

As the oxidizing agent are mainly hydrogen peroxide or its addition compounds of urea, melamine, sodium borate or sodium carbonate in the form of a 1- to 12prozentigen, preferably a 3- to δprozentigen, aqueous solution into consideration. For remedies with simultaneous whitening or bleaching may vary depending on the used Dye of formula (1) additionally persulfates, z. For example, ammonium persulfate, potassium persulfate or sodium persulfate can be added. The weight ratio between dye carrier mass and oxidizing agent is in this case preferably about 5: 1 to 1: 3, in particular 1: 1 to 1: 2. Larger amounts of oxidizing agent are mainly used at higher concentrations of oxidative dye precursors in the colorant, or when at the same time a greater bleaching of the keratin fiber (especially the hair) is intended.

The pH of the ready-to-use dyeing agent according to the invention can be adjusted so that it can be applied undiluted, or it is adjusted to a pH when mixing the dye-carrier mass with a diluent (conditioner, water, etc.) or the oxidizing agent. which is determined by the pH values of the dye carrier mass and of the diluent or of the oxidizing agent and by the mixing ratio.

The ready-to-use agent has a pH of from 2 to 11, preferably a pH of from 5 to 11. The setting of an alkaline pH is preferably carried out with ammonia, but also organic amines, for example 2-amino-2-methyl-1-propanol, tris (hydroxymethyl) amino-methane, monoethanolamine and triethanolamine, or mixtures of organic amines and ammonia and inorganic bases such as sodium hydroxide and potassium hydroxide can be used. If the pH is too high, it can be corrected with inorganic or organic acids, for example phosphoric acid, acetic acid, lactic acid, ascorbic acid, citric acid or tartaric acid. Subsequently, sufficient for the dyeing treatment amount, generally about 60 to 200 grams, pure or of the mixture on the keratin fiber and leaves the dyeing preparation at about 15 to 50 ⁰ C, preferably 30 to 40 ⁰ C, about 10 to 45 minutes long, preferably for 30 minutes, act on the keratin fiber, then rinsed the keratin fiber with water and dried. Optionally, following this rinse, it is washed with a shampoo and optionally rinsed with a weak organic acid such as citric acid or tartaric acid. Subsequently, the keratin fiber is dried.

The dyeing center! with canonical azacyanine dyes of the forms! (I) allows, inter alia, a simple and gentle coloring of differently damaged hair (for example, re-dyeing already oxidatively dyed hair lots), wherein the pre-damaged hair parts (for example, the hair tips) the color carrier mass without oxidizing agent -pur or mixed with an acidic, neutral or basic aqueous diluent is applied, while on the little or no pre-damaged hair parts (for example, the young hair) mixed with the oxidizing agent color carrier mass is applied. The aqueous component used for dilution may contain the abovementioned customary additives for solutions, creams, emulsions or gels. This method allows for color matched to the hair texture, which are characterized by a hair-friendly balance between approach and tips, which is not possible with the use of conventional oxidative hair dye, since the coupling of the dye precursors always an oxidizing agent is needed. The colorant according to the invention is characterized by colorations with particularly high color intensity and luminosity, good color balance between damaged and undamaged hair (such as between hair tips and hair offspring), good durability, very good hair care and variable applications with and without oxidant.

Another object of the present application are novel asymmetric cationic azacyanine dyes of the formula (I), which are to be understood as asymmetrically those compounds of formula (I) in which the seated on the nitrogen radical B is different from that also sitting on this nitrogen ring system ,
