    • Disclosed in a color photograph containing a storability-improving compound capable of forming a chemical bond with an aromatic amine series color developing agent that remains in a photographic material after having been processed for color development to give a chemically inactive and substantially colorless compound in at least one photographic layer on a support. Also disclosed is a method for preparation of color photographs wherein a photographic material containing a silver halide emulsion layer and a color image-forming coupler capable of forming a dye by an oxidation-coupling reaction with an aromatic amine series color developing agent, as coated on a support, is imagewise exposed to light and then subjected to photographic processing, comprising carrying out the photographic processing in the presence of the afore described storability-improving compound. By the use of the storability-improving compound, the color images formed on the color photographs do not fade when stored for long periods of time.
    • 公开在含有能够与芳族胺系彩色显影剂形成化学键的储存性提高化合物的彩色照片中,所述芳香族胺系彩色显影剂在经过显色处理后保留在照相材料中,以至少至少产生化学惰性和基本上无色的化合物 支持上的一个照相层。 还公开了一种制备彩色照片的方法,其中含有卤化银乳剂层的照相材料和能够通过与芳族胺系彩色显影剂的氧化偶合反应形成染料的彩色成像剂,涂覆在 支撑体,成像曝光,然后进行照相处理,包括在上述保存性改善化合物的存在下进行照相处理。 通过使用保存性提高化合物,在长时间存储时,彩色照片上形成的彩色图像不会褪色。
