Abstract: A stencil paper for mimeography is disclosed. The paper is comprised of a porous base which is permeable to mimeographic ink, having thereon a heat-sensitive layer of a material that is solid at ordinary temperatures but which liquifies upon heating. A process for making a stencil is also disclosed, which comprises placing the stencil paper in contact with a receiving medium and selectively heating the stencil paper to liquify portions of the heat-sensitive layer, and allowing the liquified portions of the heat-sensitive layer to transfer to the receiving medium.

Abstract: A two-color copying machine includes a scanner unit for simultaneously generating signals representing different colors on an original document and first and second thermal head assemblies each responsive to signals representing a different color image for recording two different color images on a single recording sheet. If desired, only one of the color portions of the original may be recorded, or they can both be recorded in a single recording color.
