ABSTRACT:
An electrophotographic material for color proofing which comprises a substrate, a photoconductive layer and a transfer layer in this order, and is used for preparing a color proof in a process wherein at least one color toner image is electrophotographically formed on the transfer layer and then transferred together with said transfer layer to a sheet material to prepare the color proof, wherein said photoconductive layer comprises a polymer (P) and/or a polymer particle (L) which contain units having fluorine atom(s) and/or silicon atom(s) at least in the region near the surface facing said transfer layer and the surface of said photoconductive layer which contacts with the transfer layer has tack strength of not more than 150 gram.multidot.force, which is measured by Pressure Sensitive Tape and Sheet Test of JIS Z0237-1980.
