Sensitometric and spectroscopic techniques are used to study the effect of 4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene (TAI) during the sulphur sensitization of AgBr octahedra. TAI increased the speed of an oversensitized emulsion, causing it to have a speed comparable with the optimally sulphur-sens...
