Contact reflex manifold imaging process

摘要

A contact reflex manifold imaging process is provided wherein a manifold set comprising an electrically photosensitive imaging layer which is structurally fracturable in response to the combined effect of an applied electric field and exposure to electromagnetic radiation to which the layer is sensitive releasably resides on a transparent donor sheet and is in contact with a transparent receiver sheet. A master to be copied is placed in contact with one side of the manifold set and is exposed to a pattern of electromagnetic radiation to which the imaging layer is sensitive by passing the electromagnetic radiation through the manifold set while the imaging layer is subjected to an electric field. Upon separation of the manifold set while under a field and after the exposure, the imaging layer fractures in imagewise configuration whereby a positive image is observed on one of the donor and receiver sheets and a negative image is observed on the other sheet.
