    • A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the desired image on the surface using an aqueous emulsion of an organic film-forming polymer which has been prepared by emulsion polymerization, whereby the polymer adheres to the surface of the printing plate forming an oleophilic film. The polymer preferably has functional groups such as sulphonate that bind the polymer to the hydrophilic surface. Preferably the polymer has a glass transition temperature of not greater than about 105° C. and where the glass transition temperature is above 50° C. the polymer, after deposition on the plate, is preferably subjected to a heat treatment to assist in film formation.

    • The present invention provides a planographic printing element suitable to receive and bond with a subsequently applied hydrophilic layer comprises a substrate layer, such as polyester film or paper, having coated thereon an adhesion layer, said adhesion layer comprising a polymer having a glass transition temperature of less than 15C and containing functional groups such as hydroxyl, epoxy or glycidyl groups capable of reacting with the hydrophilic layer. The polymer may be a terpolymer of a hydroxyalkyl methacrylate, an alkyl acrylate and an aminoalkyl methacrylate. The polymer may be mixed with gelatin and the mixture applied to the substrate as a coating. The hydrophilic layer, which may comprise metal oxide particles, such as aluminium oxide and/or titanium dioxide particles in a sodium silicate binder, is subsequently applied as a coating to the adhesion layer.
