  • Image recording medium employing photoconductive granules and a heat disintegrable layer
    Patent number: 4052208
    Abstract: An image recording medium for recording incident radiation to provide a positive transparency is constructed of two electrically conductive composite layers containing photoconductive material between them. One of the conductive layers is opaque and the other is transparent to the incident radiation. A voltage, sufficient to cause holes to be produced in the opaque conductive layer in response to the incident radiation, is applied between the conductive layers. Various systems for controlling the recording process are described.
