摘要:
The present invention is an imaged photographic element which includes a support, at least one light sensitive silver halide emulsion layer superposed on the support, and an overcoat layer overlying the light sensitive silver halide emulsion layer. The protective overcoat includes a first water insoluble polymer having a Tg less than 25.degree. C. and a second water insoluble polymer having a Tg greater than 25.degree. C. The first or second polymer is composed of a monomer at a weight percent of 20 to 100 having the following formula ##STR1## wherein: X is selected from the group consisting of --Cl, --F, and --CN, and Y is each independently selected from the group consisting of H, Cl, F, CN, CF.sub.3, CH.sub.3, C.sub.2 H.sub.5, n--C.sub.3 H.sub.7, iso--C.sub.3 H.sub.7, n--C.sub.4 H.sub.9, n--C.sub.5 H.sub.11, n--C.sub.6 H.sub.13, OCH.sub.3, OC.sub.2 H.sub.5, phenyl C.sub.6 F.sub.5, C.sub.6 Cl.sub.5, CH.sub.2 Cl, CH.sub.2 F, C.sub.2 F.sub.5, n--C.sub.3 F.sub.7, iso--C.sub.3 F.sub.7, OCF.sub.3, OC.sub.2 F.sub.5, OC.sub.3 F.sub.7, C(CF.sub.3).sub.3, CH.sub.2 (CF.sub.3), CH(CF.sub.3).sub.2, --COCF.sub.3, COC.sub.2 F.sub.5, COCH.sub.3, COC.sub.2 H.sub.5.
