ANODE SURFACE COATING AGENT FOR ELECTRIC COAGULATION PRINTING AND ELECTRIC COAGULATION PRINTING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an anode surface coating agent not increasing the viscosity of electric coagulation printing ink during printing and not bringing about back staining undesirable to the non-image part of a material to be printed and an electric coagulation printing method capable of forming electric coagulation printed matter free from the lowering of image quality caused by back staining. SOLUTION: A process preparing an anode surface coating agent for electric coagulation printing containing isostearic acid, an anode having a passive surface and a cathode, a process coating the surface of an anode with liquid microdroplets of the anode surface coating agent for electric coagulation printing containing isostearic acid, a process forming dots of coagulated ink corresponding to a desired image on the surface of the anode by the electric coagulation of printing ink containing an electrolytically coagulable polymer charged in the gap between the anode and the cathode and a process transferring the dots of the coagulated ink to a material to be printed to form an image are included.
