Comparison of Bromide, Benzotriazole, and Phenyl Mercaptotetrazole and Their Effect on Photographic Development

Author

Abstract

A comparison of three commonly used antifoggants was made. Their effect on the formation of fog and image density development was studied using a rate factor of development. This rate factor is defined as the slope of the curve for density-log development time. Bromide and benzotriazole were found to have no effect on the rate of development whereas 1-phenyl-5-mercaptotetrazole was found to significantly reduce the rate of development. Bromide and benzotriazole were found to cause a suppression of image density only by increasing the time before density formation begins.
