    • This invention relates to a method of processing color photographic film that has been imagewise exposed in a camera, 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, binder, and dye-providing coupler, which method in order comprises (a) thermally developing the film step without any externally applied developing agent, comprising heating said film to a temperature greater than 80null C. in an essentially dry process, such that an internally located blocked developing agent in reactive association with each of said three light-sensitive units becomes unblocked to form a developing agent, whereby the unblocked developing agent forms dyes by reacting with the dye-providing couplers to form a color image; (b) scanning the color image in the film without desilvering; (c) desilvering said film in one or more desilvering solutions to remove at least silver halide, thereby forming an improved color image suitable for scanning or optical printing, and (d) either optically printing or scanning the color image in the film following desilvering. In one embodiment of the invention, the film is scanned a first time in step (b) to obtain a relatively low quality scan and then scanned a second time after step (c) to obtain a relatively high quality scan that is used for making the positive image print.
    • 本发明涉及一种在相机中成像曝光的彩色照相胶片的处理方法,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感光单元,每个单元包括至少一个发光元件, 敏感的卤化银乳剂,粘合剂和染料提供成色剂,该方法按顺序包括:(a)不用任何外部施加的显影剂热显影该膜步骤,包括将本膜基本上加热至大于80℃的温度 使得与所述三个感光单元中的每一个反应性结合的内部定位的阻挡显影剂变得未封闭以形成显影剂,由此未封闭的显影剂通过与提供染料的成色剂反应形成染料以形成颜色 图片; (b)扫描胶片中的彩色图像而不脱色; (c)在一个或多个脱溶液中除去所述薄膜以除去至少卤化银,从而形成适于扫描或光学印刷的改进的彩色图像,以及(d)在脱银后光学打印或扫描薄膜中的彩色图像。 在本发明的一个实施例中,在步骤(b)中第一次扫描胶片以获得相对较低质量的扫描,然后在步骤(c)之后第二次扫描,以获得相对高质量的扫描,用于制作 正面图像打印。
