    • In a process and an apparatus for the exposure and development of photographic images according to the dye diffusion process a monosheet material is used, the laminated structure of which is divided by a layer which is impermeable to light but permeable to moisture into a photosensitive side of the sheet for image-wise exposure and a non-photosensitive side for observation and supplying the activator or developer solution. The said monosheet material is exposed image-wise in the dark and the photosensitive side then sealed in a light and moisture proof manner in a development apparatus in which the non-photosensitive side of the monosheet lies open and is exposed to an activator in daylight so that the image formation takes place visibly. Once the image quality has been achieved the development is stopped by removing the activator and by subsequent rinsing. The monosheet is dried in a conventional manner but only on one side.
    • 在根据染料扩散方法曝光和显影摄影图像的方法和装置中,使用单片材料,其层叠结构被不透光的层除去但是可渗透到感光侧的感光侧 用于图像曝光的片材和用于观察和供应活化剂或显影剂溶液的非感光侧。 所述单片材料在黑暗中以图像方式曝光,然后在光敏和防湿方式下密封在显影装置中,其中单片板的非感光侧打开并在日光下暴露于活化剂 图像形成发生明显。 一旦图像质量已经达到,通过去除活化剂和随后的漂洗来停止显影。 单体片以常规方式干燥,但仅在一侧干燥。
