AZO DYES, AZO DYE-RELEASING COMPOUNDS AND PHOTOGRAPHIC PRODUCTS AND PROCESSES EMPLOYING THEM

摘要

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 electron withdrawing groups in each of the position ortho to the phenolic hydroxy group.
