Dyes having structure ##STR1## 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, R.sup.1 and R.sup.2 each independently represents substituted or unsubstituted alkyl or aryl, or taken together with R.sup.5, R.sup.6, N and the carbon atoms to which they are attached, represent the atoms needed to complete a julolydyl ring, R.sup.3 represents H, or substituted or unsubstituted alkyl or aryl, R.sup.5 and R.sup.6 each independently represents H, or R.sup.5 taken together with R.sup.1, or R.sup.6 taken together with R.sup.2, 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.
具有结构##STR1##的染料,其中A代表取自以下群组的具有羧基苯基或磺酰胺苯基取代基的取代或未取代核:不带任何通过羧基与之连接的取代基的2-吡唑啉-5-酮,罗丹宁,海因氏酰脲,2-硫代海因氏酰脲,4-硫代海因氏酰脲,2,4-噁唑烷二酮,2-硫代-2,4-噁唑烷二酮,异噁唑烷酮,巴比妥酸衍生物,2-硫代巴比妥酸衍生物和吲哚二酮,R代表氢,取代或未取代的1至4个碳原子的烷基或苄基,R.sup.1和R.sup.2各自独立地代表取代或未取代的烷基或芳基,或与R.sup.5、R.sup.6、N和它们连接的碳原子一起形成完成茱萸基环所需的原子,R.sup.3代表H,或取代或未取代的烷基或芳基,R.sup.5和R.sup.6各自独立地代表H,或R.sup.5与R.sup.1一起,或R.sup.6与R.sup.2一起,代表形成类似四氢喹啉的环所需的原子,m为0或1。这些染料可用作摄影滤光片中的滤色染料。
