Title: Protecting layer for gelatin based photographic products containing 1H-pyrazolo[1,5,-b][1,2,4]triazole-type magenta coupler

Abstract: An overcoat composition comprising a water insoluble polymer having a Tg equal to or less than C. and comprising 75 to 100 weight percent of the monomer having the following formula: ##STR1## wherein: X is selected from the group consisting of Cl, F or 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 ; and wherein said overcoat composition being superposed on an imaged light sensitive silver halide emulsion layer on a support, said silver halide emulsion layer containing 1H-pyrazolo[1,5-b][1,2,4]triazole type of magenta coupler. Optionally, the polymer composition may contain a second polymer having a Tg greater than C.
