    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: A compound of the formula: where R is hydrogen, C1-C4-alkyl, phenyl, chlorophenyl, methylphenyl, methoxyphenyl or nitrophenyl; R1 is allyl, C1-C8-alkyl, C1-C8-alkyl substituted by C1-C8-alkoxy, phenoxy, phenyl or C1-C8-alkanoyloxy, cyclopentyl, cyclohexyl, methylcyclohexyl, norbornyl, phenyl or phenyl substituted by chlorine, methyl or alkoxy; R2 is C1-C10-alkanoyl, C1-C10-alkanoyl substituted by alkoxy or phenoxy, cyclohexanoyl, benzoyl, benzoyl substituted by chlorine, methyl or methoxy, C1-C8-alkoxycarbonyl, aminocarbonyl, phenylaminocarbonyl, CH3NHCO, C2H5NHCO, C3H7NHCO, C4H9NHCO, (CH3)2NCO, CH3SO2, C6H5SO2 or p-CH3-C6H4-SO2; or R1 and R2, together with the nitrogen atom, form a ring system, and K is a radical of a coupling component. The isothiazolylylazo compound of the invention is useful for the dyeing of the polyesters, nylon, and cellulose esters.
