| titleOfInvention | PROCEDURE FOR THE PRODUCTION OF HETEROCICLIC AROMATIC PIGMENTS. |
| abstract | Process for the production of heterocyclic aromatic pigments, especially benzo- [g] -naft- [2,3-b] -indolizin-8,13-dion-14-carboxyarylamide, of formula I **(See formula)** where A is an arylenic radical unsubstituted or substituted with one or more halogen atoms or with groups of lower alkyl, lower alkoxy, aryloxy or halogen-substituted aryloxy, and B is a phenyl group or an alpha- or beta-naphthyl group unsubstituted or substituted with one or more halogen atoms or with groups of lower alkyl, lower alkoxy, trifluoromethyl, cyano, lower alkanoyl, aryl, nitro, carbamyl substituted with lower alkyl, lower alkyl substituted sulfamyl, lower alkyl sulfonyl, aryl sulfonyl, lower alkyl substituted carbonylamino, lower alkyl substituted sulfonylamino or lower alkoxy substituted carbonylamino, characterized in that it consists in reacting a benzo- [g] -naft- [2,3-b] -indolizin-8,13-dion-14-carboxylic acid halide, of formula II **(See formula)** where "halogen" is chlorine or bromine, with a substituted or unsubstituted 2-, 3- or 4-aminobenzanilide, or a substituted or unsubstituted 2-, 3- or 4-amino-N- (1- or 2-naphthyl) -benzamide of the formula III H2N-A-CO-NH-B (III) where A and B have the meaning stated above.
