Abstract

The invention relates to the field of film- and photo industry. A process for obtaining of cyanine dyes by interaction of quaternary salt of nitrogenous heterocyclic compound. A compound comprises active methyl group with a derivative of nitrogen-containing base, containing alkoxy-, or acetanilino-, or sulpho-, or methylmerkaptogroup in α- or γ -position to cyclic nitrogen atom, or with 1,2-dichloro-3,4,5,6-tetrafluorocyclohex-1-ene in dimethylsulphoxide or acetonitrile medium in the presence of condensing agent at 20 - 40°C. Triamidophosphazomethane of formula [(C2H5)2N]3 P=N-CH3 is used as a condensing agent.
