Abstract

Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a novel releasable azo dye. The dyes are azophenols, or precursors of azophenols, and have an electron withdrawing group in one of the positions ortho to the phenolic hydroxy group and a carbamoyl electron withdrawing group in the other position ortho to the phenolic hydroxy group.
