    摘要： Intramolecular nucleophilic displacement compound or a precursor thereof wherefrom during photographic processing a photographically useful group can be split off, said intramolecular nucleophilic displacement compound or precursor thereof corresponding to the following general structure (I): ##STR1## wherein Nu.sup.1 represents a nucelophilic group e.g. HO, H.sub.2 N or Hs, or a precursor of such nucleophilic group e.g. an oxidized nucleophilic group e.g. O.dbd. or HN.dbd., or RO wherein R is an alkyl, an acyl, an aryl or a trialkylsilanyl group, which groups may be substituted, the said nucleophilic group or precursor thereof being located in adjacent position to C(R.sup.1 R.sup.2) so as to make possible elimination of PUG through a nucleophilic displacement reaction;Ar represents an aryl group or a heteroaryl group (e.g. pyridine), which groups may be substituted by one or more mono-atomic or poly-atomic groups, e.g. alkyl groups, nitro groups, cyano groups, carboxy groups, or by sibstituents which, when in adjacent positions on the ring, together form a ring fused with the (hetero)aryl group, e.g. a benzene ring, a cyclohexane ring, a heteroannulated ring; Ar may comprise as substituent e.g. another nucleophilic group Nu.sup.2 (same as or different from Nu.sup.1);each of R.sup.1 and R.sup.2 (same or different) represents hydrogen or an alkyl, an aryl or an aralkyl group which groups each may be substituted;R.sup.3 represents an alkyl, an aralkyl, an alkyloxy, an aryloxy, an alkylthio, an arylthio, an amino group which groups each may be substituted, an oxy (O.sup.-) or a hydroxy group;PUG is a group containing a hetero atom (selected from among N, S and O) through which it is attached to the phosphor atom and producing a photographically useful activity after cleavage of the bond between the hetero atom and the phosphor atom.
