Abstract

Procedure for the preparation of the azo compounds of the general formula **(See formula)** in which D means the radical of a diazo component; R1 and R2 each signify a hydrogen atom or a substituent; and R2 signifies a substituent, and that they contain at least one carboxylic group, which, however, must be linked directly to the ring in a position not neighboring the azo bridge, characterized by coupling diazoic amine compounds of the formula D-NH2 with hydroxypyridonic compounds of the formula **(See formula)** or the formula **(See formula)** to form compounds of the formula (l) or respectively of the formula **(See formula)** in which the two nitrogen atoms of the pyridonic radical are linked together by means of a carbon bridge with formation of a second ring, while D, R2 and R3 have the same meaning as in claims 1 to 8, for which Which starting materials are chosen so that the molecule of the azo compound contains a carboxylic group linked directly to the ring in a position not neighboring the azo bridge.
