Claims
- 1. A photographic element comprising a support; a layer comprising silver halide emulsion; and a layer containing non-uniformly and imagewise the reaction product of
- (a) a photographically useful and/or active fragment having appended thereto a moiety selected from the group consisting of ZNHR, --SO.sub.2 NHR and ##STR88## wherein R is H or alkyl and Z is selected from the group consisting of alkylene, arylenealkylene, cycloalkylene and with R can be taken together with the NH to complete an N containing heterocyclic group and (b) a polymeric mordant, wherein said polymer contains recurring units having the formula selected from the group consisting of ##STR89## wherein R.sup.2 is H or alkyl;
- R.sup.1 is H, alkyl or aryl;
- L is a bivalent linking group providing a linkage between the vinyl group and W selected from the group consisting of alkylene, arylene, arylenealkylene, COOR.sup.3 and CONHR.sup.3 ;
- R.sup.3 is selected from the group consisting of alkylene, arylene and arylenealkylene;
- W is an electron withdrawing group selected from the group consisting of SO.sub.2, CO, ##STR90## m is 1 or 2; n is 0 or 1;
- with the proviso that when n is O, W is SO.sub.2 or ##STR91## and X is a leaving group which can be displaced by nucleophiles or eliminated in the form of HX by treatment with base;
- wherein said reaction product is formed (a) by displacement of X by said moiety in recurring unit (1), or (b) by addition of said moiety to the double bond of recurring unit (2).
- 2. The photographic element of claim 1 wherein the silver halide emulsion is in the same layer as the reaction product.
- 3. The photographic element of claim 2 wherein said photographically useful and/or active fragment is a dye or dye precursor.
- 4. The photographic element of claim 1 wherein said polymer contains recurring units having the formula selected from the group consisting of: ##STR92## said photographically useful and/or active fragment having appended thereto ZNHR when the polymeric mordant is anionic and said fragment having appended thereto ZNHR, --SO.sub.2 NR or ##STR93## when the polymeric mordant is cationic or nonionic.
- 5. The photographic element of claim 1 wherein said polymer containing recurring units has the formula selected from the group consisting of ##STR94## wherein said photographically useful and/or active fragment has appended thereto the moiety ZNHR when the polymeric mordant is cationic or nonionic and said moiety being ZNHR, --SO.sub.2 NHR or ##STR95## when the polymeric mordant is cationic.
- 6. The photographic element of claim 1 wherein said polymer is cationic and contains recurring units having the formula selected from the group consisting of ##STR96## said photographically useful and/or active fragment having appended thereto a ZNHR moiety.
- 7. The photographic element of claim 1 wherein said photographically useful and/or active fragment is a dye or dye precursor.
