    摘要: 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.

    摘要: Compounds of the general formula I ##STR1## where B is a bridge member,the radicals R independently of one another are hydrogen or substituted or unsubstituted alkyl, or two radicals R together with the nitrogen are a heterocyclic saturated 5-membered or 6-membered ring,the radicals R.sup.1 independently of one another are hydrogen or C.sub.1 -C.sub.4 -alkyl,the radicals R.sup.2 independently of one another are hydrogen, C.sub.1 -C.sub.4 -alkyl or halogen,the radicals R.sup.3 independently of one another are hydrogen or substituted or unsubstituted alkyl or together are an alkylene group, and X.crclbar. is an anion. The compounds of the formula I are particularly suitable for dyeing paper.
