    摘要： Solid particle dispersions of dyes according to the formula: ##STR1## are useful as filter dyes in photographic elements. In this formula, n is 0 or 1. R.sub.1 and R.sub.2 are each independently substituted or unsubstituted alkyl or substituted or unsubstituted aryl, or taken together with R.sub.6, R.sub.7, N and the atoms to which they are attached, represent the atoms necessary to complete a julolydyl ring.R.sub.3 is H, substituted or unsubstituted alkyl, or substituted or unsubstituted aryl.R.sub.4 and R.sub.5 each independently represents H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, secondary or tertiary amino, CO.sub.2 H, or NHSO.sub.2 R.sub.8, with the proviso that at least one of R.sub.4 and R.sub.5 or a substituted on an aryl ring in R.sub.4 and R.sub.5 is CO.sub.2 H or NHSO.sub.2 R.sub.8. R.sub.8 is substituted or unsubstituted alkyl or substituted or unsubstituted aryl.R.sub.6 and R.sub.7 independently represents H, or R.sub.7 taken together with R.sub.2, or R.sub.6 taken together with R.sub.1, represent the atoms necessary to complete a heterocyclic ring.

    摘要： Solid particle dispersions of dyes of the formula:[D-(A).sub.y ]-X.sub.nwhereD that comprises an aromatic ring if y is O, A is an aromatic ring bonded directly or indirectly to D,X is a substituent, other than carboxy, having an ionizable proton, either on A or on an aromatic ring portion of D, having a pKa of about 4 to 11 in a 50/50 mixture (volume basis) of ethanol and water,y is 0 to 4,n is 1 to 7, andthe compound has a log partition coefficient of from about 0 to 6 when the compound is in unionized form,are disclosed for filter dye layers of photographic elements. They may be coated in layers of photographic elements without a mordant, and they do not wander at coating pH's. At processing pH's, however, they are solubilized for easy removal and/or decolorization.

    摘要： Dyes according to the formula: ##STR1## are useful as filter dyes in photographic elements. In this formula, n is 1 or 2. R.sub.1 and R.sub.2 are each independently substituted or unsubstituted alkyl or substituted or unbsubstituted aryl, or together represent the atoms necessary to complete a substituted or unsubstituted 5- or 6-membered ring. Also, if R.sub.7 is substituted or unsubstituted alkyl, R.sub.1 is H.R.sub.3 is substituted or unsubstituted alkyl or aryl. R.sub.4 and R.sub.5 each independently represents H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, secondary or tertiary amino, CO.sub.2 H, or NHSO.sub.2 R.sub.6, with the proviso that at least one of R.sub.4, R.sub.5, or a substituent on an aryl ring in R.sub.3, on an aryl ring in R.sub.4 or R.sub.5, on an aryl ring in R.sub.1 or R.sub.2, or on an aryl ring formed by R.sub.1 and R.sub.2 is CO.sub.2 H or NHSO.sub.2 R.sub.6. R.sub.6 is substituted or unsubstituted alkyl or substituted or unsubstituted aryl. R.sub.7 is substituted or unsubstituted alkyl, or together with R.sub.8 forms a double bond. R.sub.8 is H or together with R.sub.7 forms a double bond.
