An electrostatic recording film comprising a insulating film, a conductive layer and a dielectric layer laminated in this order, wherein said dielectric layer consisting essentially of a polymer binder, insulating grains and conductive powders and said conductive powders are fibrous conductive powders, is disclosed. The electrostatic recording film of the present invention makes it possible to give a clear and sharp image suffering from little line cutout or spotting. |

DETAILED DESCRIPTION OF THE INVENTION In the electrostatic recording film of the present invention, the weight ratio of the polymer binder to the fibrous conductive powder preferably ranges from 100/0.
1 to 100/40.
Further, in the electrostatic recording film of the present invention, the long axis of the fibrous conductive powder is preferably 1/3 to 3 times as long as the diameter of the insulating grain and the short axis of the fibrous conductive powder is preferably not more than 0.
1 times as long as the diameter of the insulating grain.
Furthermore, in the electrostatic recording film of the present invention, the insulating grains preferably comprises organic polymer grains.
Still further, the electrostatic recording film of the present invention, the back of the insulating film is preferably matted.
The polymer binder to be used in the dielectric layer of electrostatic recording film of the present invention comprises a thermoplastic resin or a hardening resin.
It may be selected from various resins commonly employed as a dielectric layer of an electrostatic recording film.
Examples of the thermoplastic resins include polyester, polyester amide, polyvinyl acetal, polyvinyl chloride, poly(meth)acrylate, polyamide, polyurethane, polycarbonate, polystyrene, polymethylpentene, alkyd resin, polyamide imide, silicon resin, fluorine resin, copolymers thereof and blends thereof.
Examples of the hardening resins which would be hardened by heat, light or oxygen include phenol resin, melamine resin, epoxy resin, crosslinked organosilicon compound and crosslinked resin obtained by adding a crosslinking agent to a poly(meth)acrylate polymer containing a reactive monomer.
These polymer binders preferably have a volume resistance of 10.

12 .
OMEGA.

cm or above.
A volume resistance lower than the above-defined value would result in an undesirable low printing density.
As a substance to be used for the conductive powder used in the dielectric layer of the electrostatic recording film of the present invention, one having a volume resistance of 10
