Abstract

1,192,602. Planographic plates. GEVAERTAGFA N.V. March 5, 1968 [March 6, 1967], No. 10475/67. Headings G2H and G2M. Planographic printing plates are prepared by developing a latent electrostatic image on a recording layer comprising an insulating binder having suspended therein an inorganic photoconductor which can provide Zn ions to form a hydrophobic image deposit, and then treating the areas not bearing a hydrophobic deposit with an aqueous solution containing a compound capable of forming a hydrophilic Zn chelate therewith or with an already formed Zn chelate. Preferably the layer is treated with a compound of formula: wherein R is H or alkyl, and Z and Z<SP>1</SP> complete nitrogen-containing ring systems preferably containing a carboxylic or sulphonic acid group, or a Zn, Cu or Co chelate of such a compound; the compound or chelate may be applied in the plate wetting soln. or printing ink, and may be mixed with a hydrophilic colloid, preferably together with a hydrophilic precipitating or hardening agent, a hygroscopic compound (e.g. a polyol), a wetting agent, a swelling agent for the recording layer (e.g. acetone or methylethylketone), a C 1-3 alkanol to lower surface tension, an acid, and a second hydrophilizing agent (e.g. a ferro- or ferri-cyanide). The recording layer may comprise ZnO in an insulating resin binder and be developed by either gilsonite powder or a liquid developer comprising a hydrocarbon carrier liquid, carbon black, zinc monotridecyl phosphate and a fixing agent formed by heating a linseed oil modified alkyd resin with white spirit.
