Abstract
An object of the present invention is to provide a support for lithographic printing plates provided with a photosensitive layer containing an acid generator and an acid-decomposable compound, that offers superior sensitivity, chemical resistance, print durability, and little scumming during printing. The present invention provides an aluminum support for a lithographic printing plate, the support being obtainable by treating a surface of an anodized aluminum plate with a treatment liquid comprising metal fluoride, metal phosphate salt, and perchlorate, and a base plate for a lithographic printing plate using the same.
