International ClassB32B 009/00Foreign Application Priority Data1988-10-28 JPAbstractAn electrostatic recording film formed by laminating an insulating film with an electroconductive layer and a dielectric layer, respectively, in which the dielectric layer contains a combination of high polymer binders comprising (A) at least one polymer selected from halogenated polyolefins, polymers of halogenated olefins and copolymers of halogenated olefins and (B) at least one polyester, the weight ratio of (A)/(B) being from 2/98 to 20/80. The film gives a high quality image in rapid recording, even after stored for a long period of time, and the image fixability of the film is excellent. | |
