Method for production of support for lithographic printing plate precursor and support for lithographic printing plate precursor

摘要

A method for the production of a support for a lithographic printing plate precursor that comprises providing on a grained aluminum support having an anodic oxide film formed thereon a layer of inorganic compound particles having a major axis larger than a pore diameter of the anodic oxide film and treating the layer of inorganic compound particles with a treating solution capable of dissolving the inorganic compound particles, thereby fusing together the inorganic compound particles to form a layer of the inorganic compound.
