[Prior art]

Conventionally, the quality of a color copy or a color printed character or image (hereinafter, simply referred to as an image) on the surface of a synthetic resin film for color copy or printing depends on the temperature and humidity of the copy or printing environment. That is, since the front and back surfaces of the synthetic resin film for color copying or printing are insulating materials, in order to prevent the generation of static electricity due to friction in consideration of running properties of the color copying machine or color printing machine, Although it was necessary to apply an antistatic agent to the back surface, even if the antistatic agent was applied, the density of images and the disturbance of images frequently occurred. As a result of diligent research, the present inventor has found that, even when the antistatic agent is applied, if the insulation electric resistance value of the applied surface exceeds a certain value, or if the antistatic agent is applied and the electric resistance of the applied surface is reduced. Even if the resistance value is suppressed below a certain value, when a matting agent made of synthetic resin powder particles or inorganic powder particles for fixing toner or preventing double feed is used, the electric resistance value partially increases and the image It was confirmed experimentally that the lightness and the disorder of Therefore, the present inventor applies these matting agents and suppresses the electric resistance value of the front surface to 10 ⁸ ohms or less even when the antistatic agent is applied, and the electric resistance value of the back surface is 10 ¹⁰ ohms. The inventors have found that if it is suppressed to a value less than that, clear images can be obtained without any practical problems, and the present invention has been completed.
