Abstract: Concentrated solutions of cationic dyes are prepared by treating the cationic dyes, which contain as the counterions the anions customarily present during their preparation, with alkali metal salts of monocarboxylic acids and with or without complexing agents in an aqueous glycol ether medium, and separating off the organic phase, which contains the dyes in the form of their monocarboxylic acid salts.

Abstract: The invention relates to a process for tanning leather by using compounds of the general formula I where m is 0 or 1 and the radicals R are independently of each other C1-C18-alkyl, which may be substituted by hydroxyl or carboxyl and/or interrupted by oxygen atoms, or else one of the radicals R is a radical of the formula where R is alkylene, which may be substituted by hydroxyl and/or interrupted by oxygen atoms.

Abstract: In the prodn. of quaternised azo dyestuffs L-het-N=N-K Ane (I) by reacting the neutral dye base Het-N=N-K (II) with an alkylating agent L-X (III), the novelty is that gamma-butyrolactone (IV) is used as the inert diluent. In (I)-(III) Ane = the equiv. of an anion; L = 1-4C alkyl; Het = a 5-membered aromatic heterocycle, which may be benzo-annellated and contains at least one N atom and 1 or 2 other hetero-atoms, selected from N, O and S, which is linked to L at a N atom; K = the radical of a coupling component of the aniline series; X = a labile gp.. Pref. (III) is di(m)ethyl sulphate. USE/ADVANTAGE - (IV) is readily biodegradable and serves well as medium for (I), allowing the reaction soln. to be used directly, without changing the diluent. (I) are obtd. in high yield and high purity and are useful for dyeing polyamide or polyacrylonitrile texti

Abstract: A transfer printing process in which a dye is transferred from a carrier to a receptor by vapourisation or sublimation of the dye by means of a thermal head, uses a carrier bearing a deprotonated cationic dye with a cyanine chromophore exhibiting at least one N-H gp. which forms part of the cyanine chromophore and which is in its electrically neutral form that is deprotonated at the N-H gp., the deporotonated dye being transferred to a coated paper receptor.

Abstract: Polymeric condensation prods. (I) contg. repeating units of formula (II) are useful as conditioning agents for the pretreatment of non-metallic surfaces (''pre-dip'') before activation for subsequent chemical metallisation. In the formulae A1 A2 = 2-4C alkylene; A3 = opt. OH-substd. 2-4C alkylene; R1, R4 = H, 1-12C alkyl or benzyl; R2, R3 = 1-12C alkyl or benzyl; R5, R6 = 1-12C alkyl, OH-substd. 2-12C alkyl or benzyl; n,m,o,p,q,r = 0 or 1. Repeating units have formula (III) (with R7, R8 = 1-12C alkyl or benzyl; s, t = 0 or 1); (I) is a condensation prod. derived from piperazine and epichlorhydrin, in which the N atoms are 0-100% quaternised with 1-12C alkyl gps. or 0-80% quaternised with benzyl gps., and is used in the form of a salt soluble in the aq. application bath; concn. of (I) is 0.001-1 wt.%, bath temp. is 10-60 deg.C and application time is 15 secs. 30 mins.
