    • A color photographic recording material containing a coupler which releases a photographically active compound.Couplers corresponding to formula (I) couple with color developers to form yellow to yellow-orange dyes and, in doing so, release the residue X as a photographically active compounds. Where X is a development inhibitor, remarkably high inter-image and edge effects can be obtained. ##STR1## in which R.sup.1 represents alkyl, a heterocyclic or carbocyclic aromatic group or -NH-CO-R.sup.2 ;R.sup.2 represents alkyl, aryl or -NH-R.sup.3 ;R.sup.3 represents alkyl or aryl;Q represents the groups to complete a fused, optionally substituted benzene or heterocyclic ring;X represents the residue of a photographically active compound;TIME represents a bond which, on reaction of the coupler with the oxidation product of a color developer, is released together with the residue X attached thereto and, in turn, releases the residue X as a photographically active compound under the development conditions;n=0 or 1.
    • 含有释放摄影活性化合物的成色剂的彩色照相记录材料。 对应于式(I)的成色剂与显色剂偶联以形成黄色至黄色 - 橙色的染料,并且在这样做时,释放残余物X作为照相活性化合物。 其中X是显影抑制剂,可以获得非常高的图像间和边缘效应。 (Ⅰ)其中R1代表烷基,杂环或碳环芳基或-NH-CO-R2; R2代表烷基,芳基或-NH-R3; R3表示烷基或芳基; Q表示完成稠合,任选取代的苯或杂环的基团; X表示摄影活性化合物的残基; TIME表示在成色剂与彩色显影剂的氧化产物反应的同时与附着于其上的残基X一起释放并在显影条件下将残留物X作为照相活性化合物释放的键, n = 0或1。
