Abstract (en)

[origin: EP1518710A2] A support for a lithographic printing plate is composed of a metal base that has been grained and anodized then subjected to treatment with an aqueous solution containing an inorganic fluorine compound and a phosphate compound, followed or preceded by treatment with a silicate compound-containing aqueous solution, and an intermediate layer which lies on the treated metal base and contains an acid group-bearing polymeric compound. Presensitized plates composed in part of the support, when used as on-machine development type plates, have a good on-machine developability, high sensitivity, long press life and good resistance to scumming. When used as positive or negative-working thermal plates, such presensitized plates efficiently utilize heat in image formation, have a high sensitivity and a long press life, and minimize scumming in non-image areas.
