Abstract
Procedure for obtaining group-free azo dyes gives carboxylic acid and sulfonic acid, which have the formula (l): **(See formula)** where R is a hydrogen atom, a halogen atom, a cyano, nitro, hydroxy or amino group or an organic radical, R1 is a hydrogen atom, an optionally substituted hydrocarbon or a heterocyclic radical or an amine group which may be substituted, R2 is an alkyl group optionally substituted with 3 or more carbon atoms, an optionally substituted aryl group or an aralkyl group, K + is a cationic group, X- is an anion and ring A may carry additional substituents or may have a ring banzo fused to it, characterized in that it comprises diazoar an aromatic amine of the formula: **(See formula)** and coupling the resulting diazonium salt with a pyridone of the formula: **(See formula)** where A, R, R1, R2, K + and X- are as defined above.
