Abstract
Several new selective development accelerators, viz. 2-[4-(2-acyl]hydr azino) anilinocarbonylmethyl] thio-5-alkylthio-1,3,4-thiadiazoles were synthesized. The structure of the compounds was confirmed by elementa l analysis, MS, IR and H-1-NMR. Their effect on the photographic chara cteristics of color negative material was studied and it was found tha t the photographic speed can be greatly increased with the inclusion o f these compounds in the color negative material.
