Imine dyes useful in photographic materials have the formula ##STR1## wherein D is selected from ##STR2## and wherein E.sup.1, E.sup.2, E.sup.3, and E.sup.4 each individually represents strongly electron-withdrawing groups; R.sup.1 and R.sup.6 each individually represents an alkyl group of 1 to about 8 carbon atoms, or an aralkyl or cycloalkyl group of 5 to about 10 carbon atoms, or an aryl group of 6 to about 14 carbon atoms; R.sup.2, R.sup.3, and R.sup.11 each individually represents an alkyl group of 1 to about 8 carbon atoms, or an alkenyl group of 2 to about 8 carbon atoms, or an aryl, aralkyl, or cycloalkyl group of 5 to about 14 carbon atoms; or R.sup.2 and R.sup.3 individually represent the non-metallic atoms necessary to form a 5- or 6-membered fused ring with the phenyl ring to which the nitrogen is attached, or together represent the non-metallic atoms required to form a 5- or 6-membered ring with each other; R.sup.4, R.sup.7, R.sup.8, R.sup.9, and R.sup.10 each individually represents hydrogen, or an alkyl , aralkyl, cycloalkyl, alkoxy, alkylamino, or alkylthio group of 1 to about 10 carbon atoms; R.sup.5 represents an alkyl group of 1 to about 8 carbon atoms, or an aralkyl or cycloalkyl group of 5 to about 10 carbon atoms; R.sup.12 represents cyano, or an aryl, aminocarbonyl, or alkoxycarbonyl group of 2 to about 8 carbon atoms, or an alkylsulfonyl, arylsulfonyl, or sulfamoyl group of 1 to about 8 carbon atoms; or R.sup.11 and R.sup.12 together represent the non-metallic atoms necessary to complete a substituted or unsubstituted ring system containing at least one 5- or 6-membered heterocyclic or unsaturated alicyclic nucleus; G represents O or C(CN).sub.2 ; Y and Z each individually represents the non-metallic atoms necessary to complete a substituted or unsubstituted ring system containing at least one 5- or 6-membered heterocyclic nucleus; M.sup.+ is a cation; L.sup.1 through L.sup.6 each individually represents unsubstituted or substituted methine groups; m is 0, 1, 2, or 3; n is 0 or 1; p is 0, 1, 2, 3, or 4; q is 0, 1, 2, or 3; and r is 0, 1, 2, 3, 4, or 5. Solid particle dispersions of dyes of formula (I) that contain at least one base-ionizable functional group such as carboxy, sulfonamido, or sulfamoyl are useful as filter dyes in photographic elements.
