A
Abstract:
Photographic recording material comprising one or more blocked photographically useful compounds. The blocked compounds are photographic image dyes and photographic reagents. These compounds are blocked with a group which, under alkaline conditions, is cleaved from the compounds by an intramolecular necleophilic displacement reaction. The compounds are resistant to unblocking under storage conditions but are uniformly unblocked under conditions encountered during photographic processing.
