Abstract

The photosensitive film consists of a coherent first phase of photosensitive material and a second, particulate second phase. The first phase changes its behaviour towards a solvent by exposure with electromagnetic radiation, i.e. it becomes insoluble, and only the unexposed areas can be washed out with the solvent. By using a second, non-coherent phase, up to 75% of the proportion of the first phase can be saved. In this way, the cost can be reduced and the film properties can be controlled by the selection of the chemical properties of the second phase. Thus, films can be activated more rapidly after actinic irradiation than hitherto and the durability of the films when used on offset printing plates was considerably increased. <IMAGE>
