Zusammenfassung:A method for making a lithographic printing plate precursor comprising the steps of: (i) providing a grained and anodized aluminum support; (ii) treating the support with an aqueous solution comprising a salt of zirconium; (iii) treating the support with an aqueous solution comprising a compound comprising a phosphonic acid group and/or an ester or a salt thereof; (iv) applying a coating comprising hydrophobic particles and a binder; (v) drying said coating. Cette invention concerne un procédé permettant de réaliser un précurseur de plaque d'impression lithographique, lequel procédé comprend les étapes qui consistent: (i) à fournir un support en aluminium anodisé et grainé; (ii) à traiter le support avec une solution aqueuse comprenant un sel de zirconium; (iii) à traiter le support avec une solution aqueuse comprenant un composé qui contient un groupe d'acides phosphoniques et/ou un ester ou un sel de celui-ci; (iv) à appliquer un enrobage qui contient des particules hydrophobes et un liant; (v) à sécher ledit enrobage.
