    摘要: This invention relates to the production of basic modified polyamides produced by the polycondensation of lactams or .omega.-aminocarboxylic acids with 0.1 to 5 mol of triamines of the formulaH.sub.2 N -- (CH.sub.2).sub.n -- NH -- (CH.sub.2).sub.n -- NH.sub.2where n equals 2 to 6 per 100 mol of lactam and 2 equivalents of carboxyl groups in the form of dicarboxylic acids and monocarboxylic acids per mol of triamine, using a molar ratio of monocarboxylic acids to dicarboxylic acids of between 10 : 1 and 1 : 20, which polyamides are dyed with reactive dyes.
