ABSTRACT:
A light-sensitive printing plate for waterless planographic printing is disclosed comprising a support, a superimposed light-sensitive layer, an outer, ink-repellent silicone rubber layer, and an inner, ink-repellent silicone layer between the light-sensitive layer and the outer silicone rubber layer, the outer silicone rubber layer having a higher degree of crosslinking than the inner layer. The printing plate is less sensitive to scratching and, at the same time, shows good developability and image resolution.
