Abstract
Acridone dyes capable of conversion to complex metal compounds are made by treating with condensing agents diphenylamine-hydroxycarboxylic acids of the general formula <FORM:0483402/IV/1> (in which in the ring I at least one position ortho to the N-atom is unsubstituted, and in which the carboxylic and hydroxy groups in the ring I are in o-position to one another), or their substitution products. The condensing agent may be concentrated sulphuric acid and the ring II may contain one or two nitro groups, or other substituents of acid nature such as halogen atoms. Starting materials specified are those obtained by condensation of 2-alkoxy- or 2-halogen-benzene-1-carboxylic acids (if desired, containing nitro groups in 3- or 5- or 3.5-positions) with o-hydroxybenzene carboxylic acids containing a primary or secondary amino group. In examples: (1) 21.41-dinitro-3-sulpho-6-hydroxydiphenylamine -5.61-dicarboxylic acid is heated with concentrated sulphuric acid (orange shades on wool, brown-red on afterchroming, and red-brown by chrome-printing on cotton); 21- or 41-nitro-3-sulpho-6-hydroxydiphenylamine-5.61 -dicarboxylic acid or 21.41-dinitro-6-hydroxydiphenylamine-5.61 -dicarboxylic acid may also be used; (2) 21.41-dinitro- or 21-or 41 - nitro - 4 - hydroxydiphenylamine-5.61-dicarboxylic acid or their 3-sulpho derivatives are heated with concentrated sulphuric acid to give a product similar to that of example 1. 21.41 - Dinitro - 3 - sulpho - 4(or 6) - hydroxydiphenylamine - 5.61 - dicarboxylic acid is made by condensing 6 (or 2)-hydroxy-3-amino-5 - sulphobenzene - 1 - carboxylic acid with 3.5 - dinitro - 2 - chlorbenzene - 1 - carboxylic acid.
