Abstract

Water-insoluble indulines are made by heating a water-insoluble blue to black dyestuff of the induline class with an alkoxysubstitution product of an amine of the benzene series. In examples, (1) nigrosine, and (2) induline are heated with 4-amino-phenolethyl-ether, and the melt poured into dilute hydrochloric acid. Specification 467,085 is referred to.
