Abstract
Abstract A transparent image-recording sheet suitable for use in a plain paper copier, comprising a transparent backing having two major surfaces, said sheet having a machine direction, and a transverse direction, at least one of the major surfaces having coated thereon, a transparent water-based toner-receptive coating comprising: a) from about 65 to about 99.9 parts of an imageable polymer; b) from about 0.1 to about 15 parts of at least one polymeric particle having a mean particle size ranging from about 1 μm to about 15 μm, and c) from 0 to about 20 parts of an antistatic agent, the toner-receptive coating being coated onto the transparent backing at a time during manufacture of the backing selected from the group consisting of a) before any orientation of said film, and b) after uniaxial orientation in the machine direction.
