Title (EN) NEGATIVE DYES AND COLORATION PROCESS USING THEM
(FR) COLORANTS NEGATIFS ET PROCEDE DE COLORATION LES UTILISANT
Abstract:
(EN) A process for coloration of a substrate comprising applying thereto at a pH above 7 a water-soluble reactive dye comprising at least three chromophoric groups linked to a polyamine. Also claimed are dyes suitable for use in the process.
(FR) L'invention concerne un procédé de coloration d'un substrat. Ce procédé consiste à appliquer sur ce dernier, à un pH supérieur à 7, un colorant réactif et soluble dans l'eau, comprenant au moins trois groupes chromophores liés à une polyamine. Sont également revendiqués des colorants pouvant être utilisés dans ce procédé.
