摘要:
An electrophotographic material for color proofing which comprises a substrate, a photoconductive layer and a transfer layer in this order, wherein said photoconductive layer comprises a polymer (P) which contains at least one polymer segment (x) containing not less than 50% by weight of units having fluorine atom(s) and/or silicon atom(s) and at least one polymer segment (Y) containing units having photosetting and/or thermosetting group(s); a polymer (Q) which contains not less than 30% by weight of units represented by the formula I--CH(a.sub.1)--C(a.sub.2)(COOR.sub.3)--wherein a.sub.1 and a.sub.2 each represents independently a hydrogen atom, R.sub.3 represents a hydrocarbon group; and contains at least one polar group such as --PO.sub.3 H.sub.2, --SO.sub.3 H, --COOH; and a polymer (R) containing at least one unit having photo and/or thermosetting group(s),the polymer (P) is present at least in the region near the surface facing said transfer layer, andthe surface of said photoconductive layer which contacts with the transfer layer has tack strength of not more than 150 gram.cndot.force.
