<p>PURPOSE:To release a photographic useful group by cleaving a single bond between nitrogen-nitrogen atoms as a tigger by incorporating a specified compd. in the titled material. CONSTITUTION:The titled material contains the novel compd. shown by formula I wherein EAG is an aromatic group capable of receiving an electron binding to NA, NA and NB are each nitrogen atom, R<1> is an isolated pair electron, a single bond (pi binding or delta binding) or a group other than hydrogen atom, (n) is 2 or 3, R<2> is R<3>-CO- or R<3>-SO2-, group, etc., R<3> is alkyl or aryl group, etc., Time is a group capable of releasing PUG group through a following reaction by cleaving the single bond between the nitrogen-nitrogen bonds as the tigger, PUG is a photographic useful group, (t) is an integer of 0 or 1, a full line is a bonding a dashed line is at least one of bonding. Thus, the titled material contains the compd. capable of releasing the photographic useful group by cleaving easily the single bond between the nitrogen-nitrogen bonds as the tigger.</p> |
