Abstract (en)

[origin: DE4407622A1] In order to improve contrast in diazofilms, the diazo compounds in the light-sensitive layer which are to be activated by exposure for colour formation are supplemented by diazo compounds in the case of which nitrogen remaining at the exposed locations and bubbles causing light scatter are produced after the action of light followed immediately by a heat treatment.
