Abstract

Improvements introduced in the object of main patent no. 368,836, granted on September 7, 1970, for: Procedure for the production of monoazoic dyes in water, free of sulfonic acid and carboxylic acid groups, which, in one of the possible forms tautomeric, are represented by the formula: ** (See formula) ** wherein R4 is hydrogen, lower alkyl, aryl, or aralkyl, R5 is hydrogen or lower alkyl, and benzene ring B may be further substituted by one or two nitro, cyano, lower alkyl, lower alkoxy, phenoxy, lower hydroxyalkoxy, or alkyl groups. (lower) lower carbonyloxyalkoxy; characterized in that they comprise diazotizing an amine of the formula: ** (See formula) ** wherein R4, R5 and B are defined as above, and coupling the resulting diazo compound with 1- (2'-ethylhexyl -) - 3-cyano-4-methyl-6-hydroxypyrid-2-one.
