Abstract

Process for preparing disazo dyes lacking aqueous solubilizing groups, and corresponding to the formula R1 - SO2 - X - A - N-N - B - N=N - D in which R1 and A mean benzene radicals, optionally substituted, X means an oxygen atom, a lower alkylene group or a bridge member of the formula. ** (See formula) ** where n represents an integer value from 1 to 5, B means a benzene or naphthalene radical in which the azo groups are in position 1,4 with respect to each other and D means a benzene radical having a hydroxyl group in position for the azo group, characterized in that the diazo compound of an aminoazoic dye lacking aqueous solubilizing acid groups, of the formula is combined R1 - SO2 - X - A-N=N-B-NH2 in which R1, X and A have the meaning already stated, and B means a benzene or naphthalene radical in which the amino and azo groups are in position for each other, with a hydroxybenzene copulating in position for the hydroxyl group.
