Red and infrared films containing either 5-thio-1,2,3,4-thiatriazoles and 5-oxy-1,2,3,4-thiatriazoles or 5-substituted-thio-1,2,3,4-thiatriazoles and 5-substituted-oxy-1,2,3,4-thiatriazoles

摘要

5-substituted-thio-1,2,3,4-thiatriazoles and 5-substituted-oxy-1,2,3,4-thiatriazoles have been found to be supersensitizers for silver halide photographic emulsions spectrally sensitized to the red and infrared regions of the electromagnetic spectrum.
