Definitions

  • the invention relates to compositions for reductive color printing, which in addition to organic sulfinic acid derivatives at least one organic compound selected from aldehydes and ketones.
  • These color proofing agents are suitable for the decolorization of colored substrates such as paper, textiles and, in particular, keratin-containing fibers, for example human hair.
  • a process for decolorization of colored substrates, as well as the use of said color proofing agent is the subject of the invention.
  • the dye In dyeing, the dye is transferred to the substrate by adsorption to the surface, by diffusion, by formation on and / or in the substrate, or by chemical bonding.
  • natural dyes such as purple or carmine were used.
  • oxidation dyes are generally suitable for dyeing, for example, paper, textiles or keratin fibers.
  • Oxidative dyes are formed by oxidative coupling of one or more developer components with each other or with one or more coupler components. Coupler and developer components are also known as Oxidation dye precursors referred.
  • the oxidative coupling preferably takes place during the dyeing process so that the dye precursors can diffuse into the substrate and the dye forms in the substrate. The size of the resulting dye molecule makes it difficult to wash out of the substrate.
  • the developer components are usually primary aromatic amines having a further free or substituted hydroxy or amino group in para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and derivatives thereof used.
  • m-phenylenediamine derivatives naphthols, resorcinol and resorcinol derivatives, pyrazolones, m-aminophenols and substituted pyridine derivatives are generally used.
  • Suitable coupler substances are in particular ⁇ -naphthol, 1, 5, 2,7- and 1, 7-dihydroxynaphthalene, 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-dimethoxypyr
  • Direct-acting dyes are generally understood to be dyes which are already preformed before the beginning of dyeing and are applied to the substrate.
  • Important representatives of this class of dyes are, for example, triphenylmethane dyes, azo dyes, anthraquinone dyes or nitrobenzene dyes, which may each carry cationic or anionic groups.
  • an important technical field is the removal of dyes. This generally refers to the removal of dyeings or prints by washing, chemical modification or destruction of the dye. The oxidative or reductive discoloration of dyed materials finds particular application in the decolorization of textiles or hair.
  • Oxidative discoloration usually leads to good results.
  • the structure of the substrate can be chemically altered by the strong oxidizing action of the decolorizing oxidizing agent. This is accompanied by an undesirable physical change of the substrate. For example, textiles or hair can become brittle or even break, especially if they are discolored several times. The visual impression, the feel as well as the durability of the substrate are negatively influenced.
  • reductive decolorizing agents scarcely discolour the natural hair color but have a reductive effect only on the dyes applied by dyeing. There is thus hardly any whitening of the hair.
  • the reductive decolorants require an improvement in decolorization performance.
  • reductive sulfur compounds for decolorization.
  • dithionites or derivatives of 1-hydroxymethylsulfinic acid or of 1-aminomethylsulfinic acid are suitable as reducing agents.
  • 1-hydroxyalkylsulfinic acids or 1-aminoalkylsulfinic acids which carry a carboxy group, a sulfonic acid group, an acyl group, an aminocarbonyl group or an alkoxycarbonyl group are suitable for decolorization of colored substrates.
  • Said derivatives have a comparable or better decolorizing power as 1-hydroxymethylsulfinic acid (vide supra).
  • WO-A1-02 / 30369 describes the discovery that with the sulfinic acid derivatives of WO-A1 -99 / 18067 keratin-containing fibers, such as, for example, hair, can be decolorized.
  • Further sulfinic acid derivatives which are suitable for decolorizing keratin-containing fibers can be found in the publications W0-A1 -03 / 026597 and WO-A1-03 / 41668.
  • the object of the present invention is to provide reductive decolorizing agents which decolorize the substrate permanently without darkening.
  • the substrate structure should be spared.
  • the reducing agents used in the decolorizing agents for a cosmetic use should be physiologically acceptable and toxicologically harmless.
  • the object is achieved by means which comprise a combination of at least one of the organic sulfinic acid derivatives according to the invention with at least one selected carbonyl compound.
  • the discoloration of colored substrates, such as paper, textiles or keratin fibers, in particular human hair, succeeds very well without darkening to a high degree after the decolorization process, as is caused by the use of the sulfinic acid derivatives alone.
  • the compositions according to the invention are particularly suitable for the fiber-sparing decolorization of keratin-containing fibers.

Abstract

La présente invention concerne des agents qui contiennent dans un excipient une combinaison de dérivés spéciaux d'acide sulfinique de formule (I), dans laquelle M représente un atome d'hydrogène ou un équivalent d'un cation monovalent ou multivalent et R est dérivé d'un peptide ou représente un radical selon une des formules (II) à (VI) (Pour la signification des constituants restants, voir la revendication 1), et d'au moins un composé choisi parmi les aldéhydes et / ou les cétones. Ces agents permettent une décoloration durable de substrats teints, sans que lesdits substrats décolorés foncent ultérieurement. Pendant le processus de décoloration, la structure du substrat est épargnée.
