    摘要： Disclosed is a process for preparing copolymers which comprises, in the order stated: (1) adding monomers containing unsaturated carbon-to-carbon bonds, a first polymerization initiator, a second polymerization initiator, and a solvent to a reaction vessel; (2) purging the resulting solution with an inert gas; (3) sealing the reaction vessel and pressurizing it by addition of an inert gas to a pressure of from about 20 to about 600 kilopascals over ambient atmospheric pressure; (4) maintaining the temperature within the pressurized reaction vessel at a temperature of from about 50 to about 100.degree. C. for a period of from about 60 to about 300 minutes; (5) thereafter maintaining the temperature within the pressurized reaction vessel at a temperature of from about 80 to about 115.degree. C. for a period of from about 30 to about 300 minutes, wherein the temperature in step (5) is higher than the temperature in step (4); and (6) subsequently maintaining the temperature within the pressurized reaction vessel at a temperature of from about 115 to about 160.degree. C. for a period of from about 30 to about 180 minutes, wherein the temperature in step (6) is higher than the temperature in step (5).

    摘要： Disclosed is a xeroprinting process which comprises(1) providing a xeroprinting master comprising(a) a substrate; and(b) a softenable layer comprising a softenable material, a charge transport material capable of transporting charges of one polarity, and migration marking material situated contiguous to the surface of the softenable layer spaced from the substrate, wherein a portion of the migration marking material has migrated through the softenable layer toward the substrate in imagewise fashion;(2) uniformly charging the xeroprinting master to a polarity opposite to the polarity of the charges that the charge transport material in the softenable layer is capable of transporting;(3) uniformly exposing the charged master to activating radiation, thereby discharging those areas of the master wherein the migration marking material has migrated toward the substrate and forming an electrostatic latent image;(4) developing the electrostatic latent image; and(5) transferring the developed image to a receiver sheet.The process results in greatly enhanced contrast potentials or contrast voltages between the charged and uncharged areas of the master subsequent to exposure to activating radiation, and the charged master can be developed with either liquid developers or dry developers.

    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.
