PURPOSE:To prevent staining of a toner image and a polyvinyl chloride film when they come into contact with each other by processing the toner image with a polymer solution to give the plasticizer resistance. CONSTITUTION:The toner image is coated with the polymer coat layer as the plasticizer resistance giving treatment to prevent direct contact between the toner image and the polyvinyl chloride film. The toner image part of a copying material is coated with the solution of the polymer, preferably, a water-soluble polymer, obtained by dissolving it in a solvent, thus permitting the polymer coat to sufficiently prevent emigration of the plasticizer, and consequently, staining of the copy and the polyvinyl chloride film due to the contact of both, the defect of the conventional toners to be eliminated. |
