Beschreibung
Zusammenfassung:	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 DEG C. and a second water insoluble polymer having a Tg greater than 25 DEG C. The first or second polymer is composed of a monomer at a weight percent of 20 to 100 having the following formula 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, CF3, CH3, C2H5, n-C3H7, iso-C3H7, n-C4H9, n-C5H11, n-C6H13, OCH3, OC2H5, phenyl C6F5, C6Cl5, CH2Cl, CH2F, C2F5, n-C3F7, iso-C3F7, OCF3, OC2F5, OC3F7, C(CF3)3, CH2(CF3), CH(CF3)2, -COCF3, COC2F5, COCH3, COC2H5.
