Abstract
A heat-sensitive lithographic printing plate precursor is disclosed which comprises a hydrophilic support and an oleophilic coating comprising an infrared absorbing agent and a developer soluble polymer which comprises a phenolic monomeric unit wherein the phenyl group of the phenolic monomeric unit is substituted by a group Q, wherein Q has the structure and is covalently linked to a carbon atom of the phenyl group and wherein L, Land Lare linking groups, a, b and c are 0 or 1, and T, Tand Tare terminal groups. The polymer, substituted by the group Q, increases the chemical resistance of the coating.
