Abstract of the Disclosure Photographically useful compounds such as photographic reagents and photographic dyes are blocked with a grouping which, under alkaline conditions, is cleaved from the compound by an intramolecular nucleophilic dis- placement reaction. The compounds are resistant to unblocking under storage conditions, but are uniformly unblocked under conditions encountered during photographic processing.
