Abstract (en)

In the process of forming an image on a light-sensitive recording material (e.g. a diazo type) a heat-developing or heat-fixing step is performed in the presence of a small amount of water, allowing employment of a temperature lower than the conventional minimum of 150 DEG C. The water may be contained in the recording material in microcapsules which are ruptured thermally or mechanically, or as water of crystallization or hydration which is released by heating. Alternatively, the water may be applied to the recording material immediately preceding, or simultaneously with, the heating step in the form of a coating or as steam.
