Abstract
Process for the preparation of asymmetric monoazo dye urea derivatives characterized in that two monoazo dyes corresponding to the formulas are treated with phosgene ** in which r1 denotes a benzoyl radical in which the groups -n = n and nh2 are located in position-p of one with respect to the other and r2 a radical linked with the azo group in position- 4 of a 1-oxybenzole-2-carboxylic acid, to which effect the starting materials are determined in such a way that the asymmetric urea derivative that is formed contains a single sulfonic acid group.
