Abstract
A photographic recording element is disclosed containing in at least one dye image forming layer unit (a) a radiation-sensitive silver halide grains include tabular grains (1) having {111} major faces, (2) containing greater than 50 mole percent bromide, based on silver, and (3) accounting for greater than 50 percent total grain projected area, (b) a fragmentable electron donating sensitizer, (c) a water dispersible cationic starch peptizer, and (d) a one equivalent dye image providing coupler. Increased photographic speed is realized.
