Abstract
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.
