ABSTRACT:
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.
