    摘要： An imaging system including a migration imaging member comprising a substrate and an electrically insulating softening layer adjacent the substrate, the softenable layer comprising a fracturable layer of electrically photosensitive migration marking material located substantially at or near the surface of the softenable layer spaced from the substrate, and a copolymer of styrene and ethyl acrylate in at least one layer adjacent the substrate, the copolymer comprising between about 40 and about 80 mole percent styrene, between about 20 and about 60 mole percent ethyl acrylate, the copolymer having a M.sub.n between about 4,000 and about 35,000, a M.sub.w between about 10,000 and about 80,000, a T.sub.g between about 30.degree. C. and about 75.degree. C., and a melt viscosity between about 1.times.10.sup.2 poise and about 1.times.10.sup.6 poise at 115.degree. C.The migration imaging member may be imaged by charging, imagewise exposing to activating radiation and developing with heat, solvent vapor, or solvent vapor pretreatment followed by heat. Some embodiments of the imaged member, wherein the softenable layer contains a charge transport material, may be utilized as a master in a zeroprinting process. The copolymer of styrene and ethyl acrylate may be in an adhesive layer of charge transport spacing layer between the substrate and the sofenable layer, or in the softenable layer itself. If desired, the copolymer in any of the aforesaid layers may be a terpolymer of styrene, ethyl acrylate and a copolymerizable organic acid having carbon-to-carbon unsaturation or a copolymerizable derivative of the organic acid.
