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: 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: The light-sensitive element has a light-sensitive registration layer applied to a dimensionally stable base, possibly using one or more intermediate layers. The layers have good photographic properties and long shelf life, and to control the photochemical properties of the light-sensitive registration layer and/or any intermediate layer present, they incorporate specific azo or azoxy dyestuffs containing sulpho groups of the type defined in more detail in Claim 1. Suitable dyestuffs to be used according to the invention may be obtained, for example, by self-condensation of 5-nitro-o-toluenesulphonic acid.

Abstract: Benzisothiazole azo dyes of the formula in which R denotes hydrogen or chlorine, R denotes hydrogen, chlorine, bromine, nitro or the radical SO2-NL L , in which L and L , independently of one another, represent substituted or unsubstituted C1-C8-alkyl, and K denotes a radical of the formula in which R represents substituted or unsubstituted C1-C12-alkyl, C5-C7- cycloalkyl, substituted or unsubstituted phenyl, pyridyl, furyl, thienyl or C1-C4-alkylthienyl and R and R , independently of one another, represent substituted or unsubstituted C1-C12-alkyl, R represents hydrogen or C1-C3-alkyl and R , R and R , independently of one another, represent hydrogen or substituted or unsubstituted C1-C12-alkyl, with the proviso that in at least one of the radicals R and R the alkyl chain is interrupted by 1 to 4 oxygen atoms and that R , R and R do not simultaneously denote hydrogen and their use for the dyeing of textile fibres.
