Abstract

Procedure for obtaining disazo dyes, free of groups that make them soluble in water, of general formula: ** (See formula) ** wherein A means a phenyl or naphthyl residue, which may contain one or more substituents that do not make it soluble in water, B means a phenylene or naphthylene residue, which may contain one or more substituents that do not make it soluble in water, characterized Why a diazo compound of general formula: A - N = N - B - N2 + II Where A and B have the meaning indicated above, it is coupled with 2,6-dihydroxy-4-methyl-3-cyano-pyridine.
