Definitions

  • a preferred embodiment of imaging medium 40 can be prepared by extruding a 0.038 mm (1.5 mil) thick receptor layer 42 comprising a blend of ethylene copolymer and a second polymer component and optionally an ionomeric resin and/or other additives onto a 0.025 mm (1 mil) thick PVC backing layer 50.
  • an imaging medium comprising a receptor layer and a backing was prepared by extruding the resins in two separate layers at a total coating thickness of 2.5 mil (0.063 mm) onto 3M 7912 white flexible PVC film which was previously described in Examples 6-12.
  • Two extruders were utilized with the extruder temperature profile and die temperature as described in Examples
