ABSTRACT:
This invention relates to novel pigmentary products, particularly valuable in the textile art, prepared by using strong acid solvents to solubilize or form fine colloidal dispersions of normally water-insoluble aryl pararosanilines in an aqueous medium. The aryl pararosaniline which is thus solubilized or dispersed is reacted with a heteropoly acid to produce water-insoluble blue-hued pigments. By various modifications in the process, the pigments can be co-precipitated with other pigments and/or dyes to produce pigments or pigment lakes of different shades and intensities.
