Dyes having the structure
wherein
A represents a substituted or unsubstituted acidic nucleus having a carboxyphenyl substituent selected from the group consisting of 2-pryazolin-5-ones free of any substituent bonded thereto through a carboxyl group, rhodanines, hydantoins, 2-thiohydantoins, 4-thiohydantoins, 2,4-oxazolidindiones, 2-thio-2,4-oxazolidindiones, isoxazolinones, barbituric, 2-thiobarbiturics, and indandiones,
R represents hydrogen, substituted or unsubstituted alkyl of 1 to 4 carbon atoms, or benzyl,
R¹ and R² each independently represents substituted or unsubstituted alkyl or aryl, or taken together with R⁵, R⁶, N, and the carbon atoms to which they are attached, represent the atoms needed to complete a julolydyl ring,
R³ represents H, or substituted or unsubstituted alkyl or aryl,
R⁵ and R⁶ each independently represents H, or R⁵ taken together with R¹, or R⁶ taken together with R², represent the atoms necessary to complete a carbocyclic ring, and
m is 0 or 1
are disclosed. The dyes are useful as filter dyes in photographic filter layers.
