Title (EN) DYE INTERMEDIATES
(FR) INTERMEDIAIRES DE COLORANT
Abstract:
(EN) Fiber-reactive dye intermediates are described that are useful for the preparation of fiber-reactive dyes. These compounds are of the formula: AeNH-(W-SO2-CH2-CH2-SO2-Y)m; where A represents hydrogen, an optionally substituted alkyl, alkoxy, or phenyl group; W represents an optionally substituted phenylene or naphthalene moiety; and m and e independently are 0, 1, or 2; the sum of m and e must be 2.
(FR) L'invention a trait à des intermédiaires de colorant réagissant sur les fibres se révélant utiles pour la préparation de colorants réagissant sur les fibres. Ces composés répondent à la formule AeNH-(W-SO2-CH2-CH2-SO2-Y)m. Dans cette formule, A représente un hydrogène, un groupe alkyle, alkoxy ou phényle, éventuellement substitués, W représente une fraction de phénylène ou de naphtalène éventuellement substituées et m et e, valent, de manière indépendante, 0, 1 ou 2, la somme de m et de e devant valoir 2.
