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.
