    • The invention relates to a method and device for processing an exposed color reversal photographic film. This method enables the water consumption of the washing baths to be limited, the water levels being maintained by a counter-current coming from the bath placed downstream, an equivalent volume of water being discharged through an overflow. The wash waters are recovered and treated by a nanofiltration unit capable of giving a permeate which can be recycled to the washing baths. This method makes it possible to overcome the problem of the presence of tin (II) in the first washing bath supplied with water by a counter-current coming from the reversal bath. This process also makes it possible to overcome the problems of discharges of chemical substances to the drains while maintaining a good sensitometry of the developed films.
    • 本发明涉及一种用于处理曝光的彩色反转摄影胶片的方法和装置。 该方法能够限制洗涤水的用水量,通过来自位于下游的浴的逆流保持水位,等量的水通过溢流排出。 洗涤水被回收并通过能够产生可以再循环到洗涤浴中的渗透物的纳滤单元进行处理。 该方法可以克服在来自反转槽的逆流中在供给水的第一洗涤槽中存在锡(II)的问题。 该方法也可以克服将化学物质排放到排水管上的问题,同时保持对显影膜的良好的感光度。

    • Rapid development of silver bromoiodide color negative photographic films and formation of high quality negative images suitable for scanning to produce display images of excellent quality is made possible by a novel developer solution composition and method of development. The solution is characterized by containing, in addition to the color developer compound and conventional photographic developer solution components, a water soluble pyrrolidone polymer, a high concentration of sulfite ion and a low concentration, or the absence of, bromide ion. In the novel method the developer composition contacts the exposed film at elevated temperature, e.g., 40 to 66° C., for a short development time, e.g., 20 to 90 seconds. The developed image has image quality suitable for scanning and digital manipulation to produce a digital record for forming a color display image of high quality.
    • 通过新颖的显影剂溶液组合物和开发方法,可以快速开发溴碘化银彩色负片照相胶片和形成适合于扫描产生优质质量的显示图像的高质量阴图。 该溶液的特征在于除了显色剂和传统的显影剂溶液组分之外,还含有水溶性吡咯烷酮聚合物,高浓度的亚硫酸盐离子和低浓度,或不含溴离子。 在新颖的方法中,显影剂组合物在升高的温度(例如40至66℃)下接触暴露的膜,持续短的显影时间,例如20至90秒。 显影图像具有适合于扫描和数字操纵的图像质量,以产生用于形成高质量彩色显示图像的数字记录。
