Reaction of p-diazobenzaldehyde hydrogen sulfate with PhNH2, PhOH, naphthylamine, and naphthol derivatives gave azo dyes containing conjugated aromatic aldehyde groups. Condensation of the aldehyde-contg. azo dyes with malonitrile gave dicyanomethylidene-contg. azo dyes and caused bathochromic shifts in the UV spectra. The dyes containing amino groups caused red shifts in acid solvents and those containing hydroxy groups caused red shifts in basic solvents.
