    • Silver halide light sensitive photographic elements are disclosed comprising a support bearing at least one yellow image forming hydrophilic colloid layer comprising a yellow dye-forming coupler and a trialkyl citrate coupler solvent of the formula C3H4(OH)(CO2R)3, where each R independently represents an alkyl group and the total number of carbon atoms for the three R groups combined is greater than 6. The combination of such citrate ester solvents with yellow dye forming couplers in photographic elements leads to both good reactivity and good image-dye light stability. The advantages of the invention are particularly useful for photographic color paper elements on reflective supports.

    • A photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide based yellow dye forming coupler and a compound of the following Formula I: wherein R1, R2 and R3 are each independently aromatic, cyclic, linear, or branched chained hydrocarbon groups. The invention provides photographic elements which exhibit exceptional yellow dye light stability, and which retain desirable properties derived from the use of acetanilide based yellow dye-forming couplers, particularly when used in combination with substituted phenolic and/or thiomorpholine dioxide stabilizers. In addition to stabilizing properties, compounds of Formula I have organic solvent properties, and accordingly may be advantageously used partly or totally in place of conventional high boiling permanent and/or auxiliary organic coupler solvents to disperse the acetanilide-based couplers.

    • In accordance with one embodiment of the invention, a photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide-based yellow dye forming coupler and a stabilizer compound of the formula S-I: wherein R0 represents an aryl or heterocyclic group; Ra is H or a substituent group; L represents an alkylene linking group and p represents 0 or 1; and Rb is a substituent group, provided that substituent groups represented by Ra and Rb may be joined to form a ring. The presence of substituted amine compounds of formula S-I improves the efficiency of dye formation reaction for acetanilide-based couplers. When used in combination with known bis-phenolic stabilizers, substantial improvements in the light stability of the image dyes can be also be obtained. Accordingly, photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield yellow dye images that have low fading when exposed to light.
    • 根据本发明的一个实施方案,公开了一种照相材料,其包含卤化银乳剂层,其具有与基于乙酰苯胺的黄色染料形成成色剂和式S-I的稳定剂化合物:其中R 0表示芳基或杂环基; Ra是H或取代基; L表示亚烷基连接基团,p表示0或1; 并且R b是取代基,条件是由R a和R b表示的取代基可以连接形成环。 式S-1的取代的胺化合物的存在提高了基于乙酰苯胺的成色剂的染料形成反应的效率。 当与已知的双酚稳定剂组合使用时,也可以获得图像染料的光稳定性的显着改善。 因此,本发明的照相元件在曝光和照相处理时表现出良好的活性,并产生当暴露于光时具有低褪色的黄色染料图像。
