SULFO GROUP CONTAINING TRIPHENDIOXAZINES HAVING AT LEAST ONE 1,3,5-TRIAZINE RING

摘要

Sulpho group-containing dioxazine compounds corresponding to the formula IMAGE +TR IMAGE in which the symbols are as defined in the specification, and salts thereof as well as dyeing preparations thereof are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, optionally combined with a special after-treatment of the dyed or printed textiles thus obtained to improve their wet fastness properties. Most preferred substrates are textile material containing or consisting of cellulose and paper.
