Abstract
Dyes of formula (1): <EMI ID=1.1 HE=28 WI=48 LX=837 LY=674 TI=CF> <PC>```wherein D is a cationic radical consisting or comprising an anthraquinone, acridine, azo, azomethine, hydrazomethine, benzodifuranone, coumarine, diketopyrrolopyrrole, dioxazine, diphenylmethane, formazan, indigoid, indophenol, naphthalimide, naphthaquinone, nitroaryl, merocyanine, methine, oxazine, perinone, perylene, pyrenequinone, phthalocyanine, phenazine, quinoneimine, quinacridone, quinophthalone, stilbene, styryl, triphenylmethane, xanthene, thiazine, thioxanthene or direct dye; may be used for dyeing keratin-containing fibres.
Description
Cationic Dyes The present invention relates to cationic dyes,
compositions thereof, and to their use for the dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or poly-amides, especially keratin-containing fibers, cotton or nylon, and preferably hair, more preferably human hair.
It is known, for example, from WO 95/01772 that cationic dyes can be used for the dyeing of organic material, for example keratin, silk, cellulose or cellulose derivatives, and also syn- thetic fibers, for example polyamides. Cationic dyes exhibit very brilliant shades. A disad-vantage is their unsatisfactory fastness to washing.
The technical problem is to provide dyes that are distinguished by deep dying having good fastness properties with respect to washing, light, shampooing and rubbing.
Accordingly, the present invention relates to cationic hair dyes of formula D is the radical of anthraquinone, acndine, azo, azomethine, hydrazomethine, benzodifuranone, coumanne, diketopyrrolopyrrol, dioxaxine, diphenylmethane, formazane, indigoid, indophenol, naphtalimide, naphthaquinone, nitroaryl, merocyani ne, methine, oxazine, pennone, perylene, pyrenequinone, phtalocyanine, phenazi ne, quinoneimine, quinacndone, quinophtalone, stilbene, styryl, triphenylmethane, xanthene, thiazine dye and thioxanthene dye; Q is C1-C30alkylene, -C2-C1 alkenylene, -C5-C1 0arylene-, -C5-C1 0cycloalkylene-or -C1 -C10alkylene(C5-C10arylene)-which may be interrupted and/or terminated at one or both ends by one or more than one -0-, -S-, -N=, -N(R1)-, SO2, -(CH2CH2-0)15-, -(CH2CH2CH2-O)15-, -C(O)-, -C(O)-C1-C12alkenylene, -C(O)O-, -OCO-, -Nt--R1 -CON(R1)-, -C(NR1R2)2-, -(R1)NC(O)-, -CSR1-or an optionally substituted, saturated or unsaturated, fused or non-fused aromatic or nonaromatic (hetero)cyclic) bivalent radical optionally comprising at least one heteroatom; -0-; -S-; -N(R1)-; SO2; -(CH2CH2-O)15-; -C(0)-; -C(O)-C1-C12alkenylene; -C(0)0-, -OCO-; -Nt-; -CON(R1)-; -C(NR1R2)2-; R1 -(R1)NC(O)-; CSR1; saturated or unsaturated, fused or non-fused aromatic or nonaro-matic bivalent radical optionally comprising at least one heteroatom; which is optionally substituted by C1-C39alkyl, C1-C30alkoxy, -C2-C12alkenyl, C5-C10aryl, C5-C10cycloalkyl, Ci-C1oalkyl(C5-C10arylene), hydroxy or D; R1 and R2 independently from each other are hydrogen; or unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted Ci-C14alkyl; C1-C14 hydroxyalkyl; C1-C14 aminoalkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl).

A further emodiment of the present inveintion relates to processes for the preparation of the dyes of formula (I).
Generally, the process comprises the reacing of dye intermediates with 3-amino-dihydro-thiophenone, which is a cyclic thioderivative according to the following reaction scheme: D An-+ Q + H2Ns DQ0 An The reaction is generally initiated by contacting, for example by mixing together the starting compounds or by dropwise addition of one starting compound to the other.
Customary, the temperature is in the range of 263-363. K, preferably in the range of 263-33Q K during the mixing of the starting compounds.
The reaction time is generally dependent on the reactivity of the starting compounds, on the selected reaction temperature and on the desired conversion. The reaction time is usually in the range fromi h to 3 days.
The selected reaction pressure is generally in the range from 10 kPa to 1 MPa, especially from 50 kPa to 150 kPa, and is more especially atmospheric pressure.
Preferably the reaction is carried out in the presence of a catalyst.
The molar ratio of compound of formula (1 b) to the catalyst is generally selected in the range from 10:1 to 1:5, especially in the range from 10:1 to 1:1.
Preferred are acid catalysts, HA and Lewis acids like Agor base catalysts as tertiary nitrogen bases In addition, the reaction may be carried out with or without a solvent, but is preferably carried out in the presence of a solvent, preferably organic solvents or solvent mixtures.
Preferred solvents are alcohols like methanol, ethanol, propariol, 2-propanol or butanol; nitnles like acetonitnl or propionitril; amides like dimethylformamide, dimethylacetamide or N- methylpyrolidone; halogenated hydrocarbons like chloroform, methylenechioride, trichloro-ethylene or chlorobenzene; or other solvents like dimethylsulfoxide or water or mixtures of the mentioned solvents.
The product prepared according to the process of the present invention may advantageously be worked up and isolated, and if desired be purified.
Customary, the work up starts by decreasing the temperature of the reaction mixture in the range from 350 to 273 K, especially in the range from 320 to 273 K. It may be advantageous to decrease the temperature slowly over a period of several hours.
In general, the reaction product is filtered off and subsequently dried.
Filtration is normally carried out in standard filtering equipment, for example Büchner funnels, filter presses, pressurised suction filters, preferably in vacuo.
The temperature for the drying is dependent on the pressure applied. Drying is usually carried out in vacuo at 50-200 mbar.
The drying is usually carried out at a temperature in the range from 313 to 363 K, especially from 323 to 353 K, and more especially in the range from 328 to 348 K. Advantageously the product is purified by recrystallisation after isolation.
The dyes of formula (I) according to the invention are suitable for dyeing organic materials, such as keratin-containing fibers, wool, leather, silk, cellulose or polyamides, cotton or nylon, and preferably human hair. The dyeings obtained are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing.
Gemerally, hair dyeing agents on a synthetic base may be classiefied into three groups: -temporary dyeing agents -semipermanent dyeing agents, and -permanent dyeing agents.
The multiplicity of shades of the dyes can be increased by combination with other dyes.
Therefore the dyes of formula (1) of the present invention may be combined with dyes of the same or other classes of dyes, especially with direct dyes oxidation dyes; dye precursor combinations of a coupler compound as well as a diazotized compound, or a capped dia-zotized compound; and/or cationic reactive dyes.
Direct dyes are of natural origin or may be prepared synthetically. They are uncharged, cationic or anionic, such as acid dyes.
The dyes of formula (1) may be used in combination with at least one single direct dye different from the dyes of formula (1).
Direct dyes do not require any addition of an oxidizing agent to develop their dyeing effect.
Accordingly the dyeing results are less permanent than those obtained with permanent dyeing compositions. Direct dyes are therefore preferably used for semipermanent hair dyeings.
Examples of direct dyes are described in "Dermatology", edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basle, 1986, Vol. 7, Ch.
