摘要：
There is disclosed a process of the manufacture of reprographic sheets for use in electrostatography and papers produced thereby. In this method a coating composition is applied to a substrate, generally paper, out of a solution of a mixture of mutually miscible organic liquids, one being a solvent for the polymer and the other a non-solvent for the polymer and removing the organic liquids with most of the solvent being removed before a significant amount of non-solvent is removed.
