An Investigation Of The Mechanism Of Emulsion Stabilization By 4-Hydroxy-6-Methyl-1,3,3a,7-Tetraazaindene, Eddie Rising
Theses
There is considerable speculation in literature as to the mechanism of photographic emulsion stabilization by 4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene, (Aza). Aza is important as a stabilizer because, unlike the heterocyclic mercaptans, it causes no desensitization when the emulsion is processed in the commonly used MQ developing agents. The mercaptans are strongly adsorbed, whereas Aza is weakly adsorbed on silver halide. Therefore, there has been speculation that the stabilization mechanism of Aza is distinctly different from that of the mercaptans. For this work, Aza was tested as an antifogging agent and development restrainer along with KBr, as a reference, in two developers which function …
