The invention relates to the use of cationic polycondensation products as additives for fixing colours and/or inhibiting the running of colours, for washing products and washing aftertreatment products. Said cationic polycondensation products can be produced by the condensation of (A1) non- cyclic amines obtained by the reaction of (A1 a) mono(N,N- dialkylaminoalkyl)amines with (A1 b) bifunctional compounds selected from the group containing urea, thiourea, dialkyl carbonates, aliphatic and aromatic dicarboxylic acids, and aliphatic and aromatic diisocyanates, in a molar ratio 1.2: 1 to 2.1: 1, or (A2) mixtures of non-cyclic amines (A1) and cyclic amines (A3) in a molar ratio 10: 1 to 1: 10 with (B) bifunctional compounds selected from the group containing alkylene dihalogenides, dihalogen alkyl ethers, halomethyl oxiranes, and bisepoxides, in a molar ratio (B) to (A1) or (B) to (A2) from 0.6: 1 to 1.3: 1.
L'invention concerne l'utilisation de produits de polycondensation cationiques fabriqués par condensation (A1) d'amines non-cycliques obtenues par réaction (A1 a) de mono(N,N-dialkylaminoalkyl)amines avec (A1 b) des composés bifonctionnels choisis dans le groupe contenant urée, thiourée, dialkycarbonates, acides dicarboxyliques aliphatiques et aromatiques et diisocyanates aliphatiques et aromatiques, dans un rapport molaire de 1,2: 1 à 2,1: 1 ; ou (A2) de mélanges d'amines non-cycliques (A1) et d'amines cycliques (A3) dans un rapport molaire de 10: 1 à 1: 10, avec (B) des composés bifonctionnels choisis dans le groupe contenant alkylène-dihalogénures, dihalogénoalkyléthers, halométhyloxiranes et bisépoxydes, dans un rapport molaire (B) sur (A1) ou (B) sur (A2) de 0,6: 1 à 1,3: 1, en tant qu'additifs de fixation des couleurs ou d'inhibition du transfert des couleurs dans des lessives et agents de traitement du linge.
