Complexing processes occurring between reactive matrices obtained from Fe(III), Co(III), Ni(II), Cu(II) hexacyanoferrates(II), and alkaline solutions of various nitrogen-sulfur-containing chelating ligands in thin gelatin layers have been studied. With Fe(III) and Cu(II) hexacyanoferrates, complexing process is found out to proceed according to S<SUB>N</SUB>1 mechanism, while in Co(III) and Ni(II) hexacyanoferrates matrices, S<SUB>N</SUB>2 mechanism is realized. The schemes of the processes proceeding in each of the above matrices are given. The examples of the kinetic curves for particular systems "hexacyanoferrate(II)-ligand" as well as spectral characteristics of thin gelatin layers containing chelate complexes formed as a result of the chelating process are presented. The possibility of practical utilization of complexing processes studied for obtaining non-silver photographic images from light-resistant metallorganic dyes is reported.
