Heat-sensitive imaging material for making lithographic printing plates requiring no processing

摘要

According to the present invention there is provided a heat-sensitive imaging material for making lithographic printing plates which require no processing. The heat-sensitive imaging element comprises on a lithographic base having a hydrophilic surface a metallic or metal oxide layer and on top thereof an oleophobic polymeric layer having a thickness of less than 5 mu m and comprising a polymer containing phenolic groups.
