Abstract

Abstract A receptor sheet manifold for thermal mass transfer imaging comprising a polymeric image receptor sheet comprising a transparent film substrate having an image receptive layer coated on at least one surface thereof which comprises at least about 90% imaging polymer, from about 1% to about 5% perfluoroalkylsulfonamidopolyether antistatic agent, and from about 0.2% to about 5% silica particles, and attached thereto is an opaque backing sheet having a contact surface touching the attached receptor sheet, and an opposing surface having a coating comprising from about 75% to about 94% of a binder resin capable of adhering thereto, from about 1% to about 10% antistatic agent and from about 5% to about 15% of a particulate, such that the opposing surface has a Bekk smoothness of about 450 to about 550 Bekk seconds.
