Abstract: A method for making a lithographic printing plate precursor is disclosed comprising the steps of:
- providing a grained and anodized aluminum support;
- treating the support with an aqueous solution comprising a compound containing a silicate anion and one or more cations;
- treating the support with an aqueous solution comprising a compound containing an organic acid group and/or an ester or a salt thereof;
- applying a coating on to said treated support comprising an image-recording layer including hydrophobic thermoplastic polymer particles having a particle size ranging between 20 nm and 55 nm.
