Abstract
A thermosensitive stencil sheet including at least a thermoplastic resin film and an electromagnetic wave absorbing layer which includes an electromagnetic wave absorbing agent and a resin. The thermosensitive stencil sheet may also include a porous substrate and/or a protective layer. A thermal stencil printing method in which the thermosensitive stencil sheet is imagewise perforated with an electromagnetic wave to prepare a stencil plate and then the resultant stencil plate is subjected to a printing operation to form images is also provided. A multi-color thermal stencil printing method using the thermosensitive stencil sheet is also provided.
