Black and white silver halide display elements having good light stability

Abstract

This invention provides a black and white silver halide photographic display element comprising a support and a layer on top of said support comprising baryta and a yellow pigment represented by Formula I wherein each of R1, R2, and R5 independently represents a halogen atom, or a substituted or unsubstituted alkyl, alkenyl, aryl, aralkyl, cycloalkyl, alkoxy, or alkyl amino group of 1 to 8 carbon atoms, or a substituted or unsubstituted aminocarbonyl, alkoxycarbonyl or alkylthio group of 2 to 10 carbon atoms, or a substituted or unsubstituted alkylsulfonyl, arylsulfonyl or sulfamoyl group of 1 to 8 carbon atoms, or a nitro, amino, acetamido, hydroxy, cyano, carboxy, carboxylate, sulfonic acid, or sulfonate group, additionally pairs of R1 or R2 may represent the non-metallic atoms necessary to complete a substituted or unsubstituted ring system containing at least one 5- or 6-membered heterocyclic or carbocylic fused ring; and n, m and r are independently 0 to 5.

Dependencies are inferred from the claim text.
