Abstract (en)
According to the present invention there is provided a heat-sensitive imaging element for making lithographic printing plates comprising a lithographic base having a hydrophilic surface, a hydrophobic first layer that is sensitive to heat including at least a hydrophobic polymer and a compound that is capable of converting light into heat, said layer having a decreased or increased capacity for being penetrated and/or solubilised by an aqueous developer upon exposure to actinic light, characterized in that said imaging element comprises a second layer located between the first layer and the hydrophilic surface and including a dispersed hydrophobic thermoplastic polymer latex, said second layer being soluble or dispersible in an aqueous solution.
