    摘要： Solid particle dispersions of dyes according to the formula: ##STR1## wherein D is selected from the group consisting of ##STR2## and ketomethylene nuclei are disclosed as filter dyes for photographic elements.In this formula, E.sup.1 and E.sup.2 are each independently electron withdrawing groups R.sup.1 and R.sup.6 are each independently R or NHR, where R is substituted or unsubstituted aryl. R.sup.2 and R.sup.3 are each independently substituted or unsubstituted alkyl or substituted or unsubstituted aryl, or represent the carbon atoms necessary to form a fused ring with the phenyl ring to which the N atom is attached. R.sup.4 and R.sup.7 are each independently hydrogen, substituted or unsubstituted alkyl or substituted or unsubstituted aryl. R.sup.5 is substituted or unsubstituted alkyl Z represents the atoms necessary to complete a substituted or unsubstituted 5 or 6 membered heterocyclic nucleus. M.sup.+ is a cation. L.sup.1 through L.sup.7 are each independently substituted or unsubstituted 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. At least one of R.sup.1 or D includes an aryl ring substituted with a carboxy or sulfonamido substituent.
