Abstract

PURPOSE: To impregnate only the recording layer with the electrolyte and save the power used for drying by forming a hydrophobic film on the surface of a paper substrate, in the electric current recording paper used for electric current recording after being impregnated with the electrolyte.
CONSTITUTION: A dispersion of an adhesive in water is applied onto the paper substrate 13 and then dried to obtain a hydrophobic film 14. A hydrophobic adhesive such as styrene-butadiene copolymer latex and polyvinyl chloride is used as the adhesive. Then the recording layer 15 consisting of a leuco dye, an adhesive, an adsorbent and a surfactant is formed on the hydrophobic layer 14. The electrolyte 2 is impregnated in the thus-obtained recording paper 1 by using an impregnation roller 3, and excess electrolyte is removed by a pair of squeeze rollers 4. Then, electric current recording is conducted by using a recording electrode 7 and a return electrode 6, the recording paper is dried by a drying unit 8 consisting of a metal plate for heating and a heater.
