ABSTRACT:
A heat-sensitive stencil sheet is disclosed, which comprises a porous sheet having on one side thereof at least an adhesive layer and a thermoplastic resin film layer in this order, wherein at least one of the layers constituting said stencil sheet contains a heat-sensitive color-forming material. The layer containing the heat-sensitive color-forming material develops a color on thermal perforation to visualize the perforated image so that a printing ink, particularly plural inks of different color, can be easily applied to the stencil sheet in proper positions in proper quantities.
