Abstract (en)

[origin: US4748098A] An emulsion for post-treating planographic printing plates prepared by electrographic means can be used to improve the print quality of treated plates. The emulsion comprises (i) about 25% to 60% by weight of an aqueous phase comprising a phosphonic acid compound and a water-soluble hydrophilizing polymer and (ii) about 40% to 75% by weight of an organic solvent phase comprising a hydrocarbon mixture containing at least 20% by weight of aromatic components. A process for the production of planographic printing plates that employs this emulsion is simplified and less costly than conventional processes, and entails fewer environmental hazards.
