摘要： Recording material, for color photography, which contains at least one piperidine compound containing one or more alkyl-substituted phenol groups, as the light stabilizer, in at least one light-sensitive silver halide emulsion layer, one interlayer and/or one protective layer. Colored images which are obtained by image-wise exposure and development of this recording material for color photography display good stability towards the action of visible and ultraviolet light.
摘要翻译： 在至少一个感光卤化银乳剂层，一个中间层和/或一个保护层中的用于彩色摄影的记录材料，其含有至少一种含有一个或多个烷基取代的酚基的哌啶化合物作为光稳定剂。 通过图像曝光获得的彩色图像和用于彩色摄影的该记录材料的显影对于可见光和紫外光的作用显示出良好的稳定性。

摘要： Color photographic material is provided which contains at least one silver halide emulsion layer containing a yellow color coupler of the formula ##STR1## wherein G is the radical of a yellow coupler which is bonded to the heterocyclic ring by means of the active methylene group, Z is --CO-- or --SO.sub.2 --, M is hydrogen if Z is --CO--, or a substituent and R is hydrogen or a substituent.The new two-equivalent yellow couplers lead due to their improved reactivity (high maximum density), minimal fog and high fastness to light and outstanding spectral properties of the dyestuffs formed therefrom to a color photographic material of advantageous properties.
