Abstract
This invention provides stencil from which a patternwise perforated stencil can be easily made by handwriting, a stencil material set with which a patternwise perforated stencil can be made, and a stencil duplicator set which, in combination with the stencil, performs simple, clear printing. The stencil is made up of a porous support and a masking film formed thereon, said masking film being made of a water-insoluble polymer having tertiary amino groups. The stencil material set contains the stencil and a patternwise perforated stencil-making solution which forms a water-soluble product upon reaction with said polymer. Stencil printing is performed using the patternwise perforated stencil, a stencil duplicator and printing ink.
