  • Patent number: 5085469
    Abstract: Flexible composite material is provided upon which a facsimile message containing both confidential and nonconfidential information can be recorded. In general, the composite material comprises a recording layer and a cover layer. The recording layer has a predetermined width and a longitudinal extent which varies in length consistent with the length of the recorded message. The cover layer is disposed over the recording layer to define a confidential message recording area and at least one non-confidential message recording area. Both message recording areas extend along the longitudinal extent of the recording layer. The cover layer permits recording upon the non-confidential area and confidential area, while concealing the confidential message prior to the cover's removal.
