| titleOfInvention | PROCEDURE FOR THE PREPARATION OF OZOIC DYES FREE OF HYDRO-SUBILIZING ACID GROUPS. |
| abstract | Procedure for the preparation of azo dyes free of hydrosolubilizing acid groups, corresponding to the formula ** (See formula) ** or to a tautomeric formula, in which R1 signifies an optionally substituted alkyl, cycloalkyl, aryl or heterocyclic radical, Z means a radical of the formulas ** (See formula) ** in which R2, R3, R4 or R5 mean, independently the same as R1 or R2 and R3 together with the nitrogen atom that binds them, eventually including another heteroatom, a non-aromatic heterocycle with 5 or 6 members, Y means the group -CONH2- or the group -CN-, D means the radical of a diazoic, aromatic or heterocyclic component, and in which at least one of the radicals Z and D has a basic group, characterized by the coupling of the diazo compound of an amine of the formula D-NH2 with a coupling component of the formula ** (See formula) ** transform the dye obtained, provided that in D and/or Z there is a non-quaternized nitrogen atom, optionally with a quaternizer, and, optionally, when Y = CN, saponify the cyano group with concentrated sulfuric acid.
