    摘要： A method of processing an imagewise exposed color photographic film, said film having at least three light-sensitive units which have their individual sensitivities in different wavelength regions, each of the units comprising at least one light sensitive silver halide emulsion and image dye coupler, which method comprises contacting the imagewise exposed color photographic film with an aqueous solution containing a non-blocked developing agent, at a temperature of between 30 to 60° C.; and wherein said film further comprises an incorporated reducing agent, at least one organic silver salt and an amido compound wherein the reducing agent is substantially unreactive in the aqueous color development step described above, but wherein color development of the same imagewise exposed film is capable of being alternatively obtained, without any externally applied developing agent, by heating said film to a temperature above about 80° C. essentially in the absence of aqueous solutions, such that the incorporated reducing agent reacts to form dye by reacting with the image dye couplers; with the proviso that the amido compound effectively reduces contrast when the film is heated above 80° C. but does not substantially reduce contrast when the film is processed by contacting the imagewise exposed color photographic film with a non-blocked developing agent under aqueous conditions, at a temperature of between 30 to 60° C.

    摘要翻译： 一种处理成像曝光的彩色照相胶片的方法，所述胶片具有至少三个在不同波长区域具有各自敏感度的光敏单元，每个单元包含至少一种感光卤化银乳剂和图像染料偶合剂，其中 方法包括使成像曝光的彩色照相胶片与含有非阻挡显影剂的水溶液在30至60℃的温度下接触; 并且其中所述膜还包含引入的还原剂，至少一种有机银盐和酰氨基化合物，其中所述还原剂在上述水性显色步骤中基本上不反应，但是其中相同的成像曝光膜的显色性能够 可替代地获得，没有任何外部施加的显影剂，通过将所述膜加热到大约80℃的温度，基本上在不存在水溶液的情况下，使得引入的还原剂通过与图像染料成色剂反应而反应形成染料; 条件是当膜被加热到80℃以上时，酰胺化合物有效地降低了对比度，但是当通过在水性条件下使成像曝光的彩色照相胶片与非阻挡显影剂接触来处理膜时，实质上不会降低对比度， 温度在30至60℃之间。
