    Abstract: Procedimiento para la preparacion de formulaciones liquidas de colorantes de formula general I (en donde Y significa cloro o bromo, Z significa hidrogeno, cloro, bromo, ester de acido sulfonico, nitro o bien sulfamoilo eventualmente sustituido, X significa o R significa alquilos eventualmente interrumpidos por oxigeno, o m representa el numero 1 o 2, n representa el numero 0 o 1, p representa el numero 0, 1 o 2, An- representa el equivalente de un anion, R1 y R2, independientemente entre ellos, representan hidrogeno, alquilo, alquenilo, cicloalquilo, aralquilo o arilo eventualmente sustituido, o bien R1 y R2 juntos con el nitrogeno que los une forman un heterociclo, R3 representa hidrogeno o bien alquilo eventualmente sustituido, B representa hidrogeno o bien alquilo C1 a C4, B1 representa hidrogeno, hidroxi, alcoxi C1 a C4 o bien alquilo C1 a C4, en donde R4 representa alquilo eventualmente sustituido y R5 representa hidrogeno o bien alquilo C1-C4 y el radical puede significar tambien un radical piperazina eventualmente sustituido, a traves de la diazotizacion de una amina de la formula II y finalmente el acoplamiento de la sal de diazonio en un enlace de la formula III asi como eventualmente la adicion de aditivos de solubilizacion en la medida en que para la diazotizacion se ajusta el valor de pH a un nivel acido a traves de adicion de acido metansulfonico puro o bien una mezcla de por lo menos 20% molar de acido metansulfonico en acidos monobasicos.

    Abstract: The invention relates to azoxy dyes of general formula (I) in their free acid form, in which n is 0 or 1, R is methoxy, hydroxyl and carboxyl, R is carboxyl, amine, C1-C4 alkylamine, allylamine, benzylamine and methoxycarbonylmethylamine and the phenyl rings A can be substituted with C1-C8 alkyl, phenyl that can be substituted with methyl or halogen, hydroxyl, amine, nitro, halogen, carboxyl, N-benzylcarbamoyl, phenylcarbamoyl and naphthylcarbamoyl that can be unsubstituted or substituted with nitro, halogen, C1-C4 alkoxy, acetoxy, or they can be benzo-anellated. The invention also relates to their Cu complexes, to a method for producing the Cu complex dyes, to azoxy dyes of formula (I) in their partially or completely deacylated form, to their Cu complexes, to dyes containing said azoxy dyes and/or to their Cu complexes and to their use for dyeing and printing natural or synthetic substrates.

    IPC: D21H21/28 ,  D21H17/06

    Abstract: In the production of coloured paper by adding paper dyes that react with bleach to an aqueous bleached pulp still containing residual bleach and draining, the bleach is first inhibited by adding at least the equivalent amount of a compound (I) containing keto or aldehyde groups. Also claimed is the use of (I) for stabilising these paper dyes against oxidative and reductive degradation in the production of coloured paper. Preferably (I) is a 1-8 carbon (C) aldehyde, a ketone or a 2-8 C dialdehyde, especially glyoxal, glyoxalic acid, succindialdehyde, glutardialdehyde, form aldehyde, acetaldehyde, propionaldehyde, n- or iso-butyraldehyde, phthaldialdehyde, benz aldehyde and/or salicylaldehyde; or acetone, diethyl ketone, methyl ethyl ketone, methyl n- or iso-propyl ketone, di-n- or -iso-propyl ketone, methyl isoamyl ketone and/or (di)hydroxy acetone. The bleach is sodium dithionite; formamidinesulphinic acid or its ammonium or alkali metal salt; ammonium or alkali metal sulphite; or hydrogen peroxide.

    Abstract: Azoxy dyes of the general formula I in the form of the free acid where n is 0 or 1, each R 1 is selected from the group consisting of methoxy, hydroxyl and carboxyl, each R 2 is selected from the group consisting of carboxyl, amino, C 1 -C 4 -alkylamino, allylamino, benzylamino and methoxycarbonylmethylamino, and the phenyl rings A may additionally be substituted by C 1 -C 8 -alkyl, unsubstituted or methyl- or halogen-substituted phenyl, hydroxyl, amino, nitro, halogen, carboxyl, N-benzylcarbamoyl, unsubstituted or nitro-, halogen-, C 1 -C 4 -alkoxy- or acetoxy-substituted phenylcarbamoyl and naphthylcarbamoyl or be benzofused, their copper complexes, a process for preparing the copper complex dyes, azoxy dyes of the formula I in their partially or completely deacylated form, their copper complexes, colorants comprising these azoxy dyes and/or their copper complexes and also their use for dyeing and printing natural or synthetic substrates.
