ABSTRACT:
A precursor element for making a lithographic printing plate is composed of a support, an ink receptive thermal conversion inner layer and a sol-gel, ink repellent outer layer. The outer sol-gel layer containes crosslinked colloids derived from certain metal oxides or hydroxides. The plates produced from the ellements are long-running plates that require no post-imaging processing.
