Article abstract of DOI:10.1016/j.saa.2012.07.013

Six new water insoluble azo-azomethine dyes have been synthesized via condensation reaction of α,α′-bis(o-aminophenylthio)-1,2- xylene with substituted azo-coupled salicylaldehyde. The condensation reaction provides the expected bis-iminated azo-azomethin
