Abstract
Room-light handleable direct silver halide emulsions exhibit a broadened Dmin window when certain nitro-substituted aryl- or heteroaryl-containing imidazoles are included. These imidazoles act as excellent rereversal and Dmin suppressants. Photographic elements are prepared from these emulsions that can be handled in room-light if desired.
