Abstract: A photographic element contains a filter dye of the Formula (I): ##STR1## wherein R.sup.1 -R.sup.4 each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group; L.sup.1, L.sup.2 and L.sup.3 each independently represent substituted or unsubstituted methine groups; M.sup.+ represents a proton or an inorganic or organic cation.

Abstract: A photographic element having a support and a layer containing first and second oxonol dyes, the first dye being a monomethine pyrazolone oxonol dye with each pyrazolone ring having a 1-phenyl group bearing an ortho-substituent selected from sulfo, sulfato, hydroxy, or nitro substituent, and the second dye being a tri- or penta-methine oxonol dye. A method of making a photographic element is also provided. The method comprises maintaining a mixture of at least such a first dye in a carrier medium at a temperature of at least 30.degree. C. for 0.5 hour.
