Abstract

PURPOSE: To remove a thermal fixing process by mixing cationic surface active agent with treating liquid for wet electrophotolithiograhic printing.
CONSTITUTION: Cationic surface active agent is dispersed or dissolved uniformly in fat-insensitive treating liquid which is made up mainly of at least one of hydrophilic resin like gum arabic, polyvinyl pyrolidone, phosphate, aluminum, alum compound, inorganic acid or organic acid and mainly of ferrocyanide, ferricyanide or mainly of a myoinositol orthohexan phospholic acid ethylene oxide derivative. When the cationic surface active agent (0.01W10% by weight) is mixed, coexistence ions come in effect in the fat-insensitive treating liquid, the toner attached onto the original plate is bound onto the original plate further more firmly and fixing of the toner to the photosensitive layer becomes firm.
