前文中我们报道了利用铜物理显影的多级放大成像过程能够明显地提高影像密度,从而大大提高了感光材料的感光度或者大幅度地降低感光材料的用银量,并且可以达到特高反差和特短趾部等特殊效果。本文介绍铜物理显影多级放大成像过程的另一种应用:在乳剂层表面或绝缘材料表面上定域沉积能导电的铜影像,为将感光胶片直接用于 In the previous section, we reported that the multistage magnification imaging process using copper physical development can significantly increase the image density, thereby greatly increasing the sensitivity of the photosensitive material or greatly reducing the amount of silver used in the photosensitive material, and can achieve super high contrast and Special short toe and other special effects. This article describes another application for multi-level magnification imaging of copper physical development: deposition of electrically conductive copper on the surface of an emulsion layer or on the surface of an insulating material for the direct application of a photographic film
