PURPOSE:To improve the transporting property at the time of copy, the image density and the toner density property of a titled film, by providing a toner receiving layer contg. an effective amount of fine powder as a mat agent on the surface of a plastic film, and by arranging so as to make the layer opaque and given with a specific surface resistivity value. CONSTITUTION:A fine powder having about 0.01-10mu average particle diameter (primary particle diameter) such as TiO2, SiO2 and polystyrene as a mat agent, is incorporated by 0.5-10wt% to a binder resin to prepare a toner receiving layer, which is provided on one surface or both sides surfaces of a plastic film such as polyester. The binder resin consists essentially of a polyester resin or an acrylic resin insoluble in an org. solvent or is subjected to the treatment making insoluble by a crosslinking etc. By this way, a film for electronic X- ray photography having 1X10<9>-1X10<15>OMEGA surface resistivity and which is opaque (The opacity for total rays being measured by JIS K-6717 is <=80%) is obtained. By using this film, the adhesive strength of toners becomes better and a copied image by which an X-ray image is discriminated exactly without using a showcase is obtained. |
