    • A colour photographic recording material having at least one red-sensitive silver halide emulsion layer which is associated with a cyan coupler, at least one green-sensitive silver halide emulsion layer which is associated with a magenta coupler, at least one blue-sensitive silver halide emulsion layer which is associated with a yellow coupler contains in at least one green-sensitive silver halide emulsion layer a 2-equivalent pyrazolone coupler and in a photosensitive or non-photosensitive layer a white coupler of the formula (I) ##STR1## in which X.sup.1 means an acyl residue derived from an aliphatic, cycloaliphatic or aromatic carboxylic or sulphonic acid, a carbonic acid semi-ester or a carbamic acid,Z means the residue required to complete a saturated or partially unsaturated 5- or 6-membered carbocyclic ring which is optionally substituted and/or provided with a further fused ring or ring system.The colour images produced using the recording material exhibit elevated storage stability without a subsequent increase in fog or a subsequent increase in colour density or spotting occurring during storage.
    • 一种彩色照相记录材料,其具有与青色成色剂相关联的至少一种感红卤化银乳剂层,与品红色成色剂相关的至少一种感绿卤化银乳剂层,至少一种蓝敏感卤化银 与黄色成色剂相关联的乳剂层在至少一种感绿卤化银乳剂层中含有2-当量吡唑啉酮偶联剂,在光敏或非感光层中含有式(I)的白色偶联剂,其中X1表示 衍生自脂族,脂环族或芳族羧酸或磺酸,碳酸半酯或氨基甲酸的酰基残基Z表示完成饱和或部分不饱和的5-或6-元碳环所需的残基,其任选被取代 和/或设置有另外的稠环或环系统。 使用记录材料产生的彩色图像表现出提高的储存稳定性,而不会随后增加雾度,或随后的颜色密度增加或储存期间发生斑点。
