摘要

PHOTOGRAPHIC PRODUCTS EMPLOYING NONDIFFUSIBLE N',N'-DIAROMATIC CARBOCYCLIC - OR DIAROMATIC HETEROCYCLIC SULFONOHYDRAZIDE COMPOUNDS CAPABLE OF RELEASING PHOTOGRAPHICALLY USEFUL GROUPS Photographic elements and assemblages are described which employ nondiffusible N',N'-diaromatic carbocyclic - or diaromatic heterocyclic sulfonohydrazide compounds which are capable of releasing photographically useful groups in an imagewise manner as a function of silver halide development.
