Abstract
Abstract Dyes having structure <IMAGE> A represents a substituted or unsubstituted nucleus having a carboxyphenyl or sulfonamidophenyl 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, barbiturics, 2-thiobarbiturics, and indandiones, R represent 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 such as tetrahydroquinoyl, and m is 0 or 1 are disclosed. The dyes are useful as filter dyes in photographic filter layers.
