Abstract
A method of making a porous, hydrophilic layer with a high surface energy on a substrate for a printing plate, ink jet receiver or the like by the steps of grinding an inorganic gel containing a liquid to provide a fine coatable dispersion of inorganic gel, coating the dispersion of inorganic gel onto the substrate, and heating the dispersion coating to provide the porous hydrophilic layer.
