  • Heat mode sensitive imaging element for making positive working printing plates
    Patent number: 6391517
    Abstract: According to the present invention there is provided a heat mode imaging element for making a lithographic printing plate having on a lithographic base with a hydrophilic surface a first layer including a polymer, soluble in an aqueous alkaline solution and a top layer on the same side of the lithographic base as the first layer which top layer is IR-sensitive and unpenetrable for an alkaline developer wherein said first layer and said top layer may be one and the same layer; characterized in that said top layer contains a polymer that lowers the dynamic friction coefficient of the top layer to less than 0.37, and wherein said polymer in the top layer is polytetrafluoroethylene.
