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.

Heat-sensitive imaging material for making lithographic printing plates

According to the present invention there is provided a method for making on-press lithographic printing plates which require no processing. The method comprises the steps of:

Heat-sensitive imaging material and method for making on-press

According to the present invention there is provided a heat sensitive imaging element comprising a lithographic base with a hydrophilic surface, an image forming layer including a hydrophobic thermoplastic polymer latex and a compound capable of converting light into heat being present in said image forming layer or a layer adjacent thereto, characterized in that the heat-sensitive imaging element comprises a barrier layer between the lithographic base having a hydrophilic surface and the image forming layer, said barrier layer and said image forming layer being removable in an aqueous solution with a pH of at least 5.
