    • A color photographic recording material having at least one silver halide emulsion layer unit containing color coupler, which unit comprises at least two adjacent silver halide emulsion partial layers of the spectral sensitivity concerned, one of which is more sensitive and one less sensitive, contains in a reactive association with at least one more sensitive silver halide emulsion partial layer having a comparatively low color coupler content relative to the silver halide content, a compound (or a precursor compound thereof), which is capable under chromogenic development conditions of forming a substantially colorless, diffusible coupling product with the color developer oxidation product, which coupling product is capable under chromogenic development conditions in the presence of an oxidising agent of forming a dye with a color coupler, with transfer of the residue originating from the color developer.On chromogenic development, color images having improved grain are obtained.
    • 一种具有至少一个含有彩色成色剂的卤化银乳剂层单元的彩色照相记录材料,该单元包括至少两个相关的光谱敏感度的相邻卤化银乳剂部分层,其中一个较敏感,一个较不敏感,含有一个 与相对于卤化银含量相对较低的成色剂含量的至少一种更敏感的卤化银乳剂部分层的反应性缔合,其化合物(或其前体化合物)能够在显色发展条件下形成基本上无色的, 可扩散的偶联产物与着色显影剂氧化产物,该偶联产物在显影发展条件下,在存在与彩色成色剂形成染料的氧化剂的情况下,转移来自彩色显影剂的残余物。 在显色发展中,获得具有改善的颗粒的彩色图像。

    • A photographic material comprising a support and at least one at least one layer which comprises at least one spectrally sensitized silver halide emulsion, characterized in that the material contains at least one compound of formula wherein X denotes sulphur or selenium, R1 denotes aryl or heterocyclyl, R2 denotes alkyl, alkenyl, alkynyl, aralkyl or hetarylalkyl, R3 denotes alkyl, alkenyl, aryl, aralkyl, hetaryl or hetarylalkyl, and R4 denotes H, alkyl, alkenyl, aryl, aralkyl, hetaryl or hetaralkyl, or R3, together with R4, denotes the remaining atoms of a carbocyclic or heterocyclic ring, is distinguished by increased spectral sensitivity, a high sensitivity/fogging ratio and a good shelf life under humid conditions.
