Phthalocyanine dyes containing an ortho-amino-sulfanilide group, and process for preparing them Abstract of the disclosure: Very valuable, new phthalocyanine compounds, suitable as dyestuffs, had been found which contain one or several ortho- amino-sulfanilide groups. These dyestuffs can be applied and fixed on various fiber-materials, especially in accordance with the old ice-color technique. The novel dyestuffs are fixed by treating them on the material on which they had been applied, by means of nitrous acid. The dyeings and prints thus obtained possess very good fastness properties, such as to rubbing, to washing and to light.
