摘要:
Phthalocyanine compounds which contain a heterocyclic fibre-reactive radical correspond to the formula ##STR1## in which the symbols are as defined in the specification, which compounds are in free acid or salt form, and mixtures thereof, are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, for example leather and fibre material comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is a textile material comprising cotton.
摘要:
Dyes of the formula in which Me, R1, X1, A, u and q are as defined in the specification are particularly suitable for dyeing cotton and produce dyeings with good all-round properties.
摘要:
Novel aluminium phthalocyanine compounds of having the formula ##STR1## and their salts wherein D represents --SO.sub.2 NR.sub.a --A--SO.sub.2 --B or ##STR2## --SO.sub.2 B is a fiber-reactive group and Z is a heterocyclic fiber-reactive group having 1 or 2 labile halogens selected from fluorine or chlorine. The novel aluminium phthalocyanine compounds and their salts are fiber-reactive dyestuffs useful in dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates.
