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.
