Abstract

Liquid dye prepns. for paper, contain 25-35 wt.% known dye of formula (I); 30-45% acetic acid; 12-22% glycolic or lactic acid; 2-8; citric or malic acid; 2-15; water; and 2-8% other prods. Crystallisation and drying-out on exposure to air, causing blocking of continuous feed equipment, as occurs with solns. in aq. acetic and formic acids, is prevented.
