Blocked photographically useful compounds and photographic compositions, elements and processes employing them |
摘要 |
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 displacement reaction. The compounds are resistant to unblocking under storage conditions, but are uniformly unblocked under conditions encountered during photographic processing.
