Abstract
A radiation sensitive emulsion is disclosed containing a silver halide grain population comprised of at least 50 mole percent chloride, based on silver, in which greater than 50 percent of the total grain projected area is accounted for by ultrathin tabular grains having a {111} crystal face stabilizer adsorbed to the major faces of the ultrathin tabular grains.
