る。 In the figure, 1 indicates the entire heat-sensitive stencil paper;
This heat-sensitive stencil paper 1 is composed of a stretched thermoplastic synthetic resin film 2 and a porous support 3, both of which are polymerized and adhered to each other by an adhesive 4. During plate making, the thermoplastic synthetic resin film 2 is placed facing the thermal head 6 of the thermal printer, and the heat of the head 6 creates dots in the thermoplastic synthetic resin film 2 with ink permeable openings 7 corresponding to the characters. At the same time as the matrix is melted and perforated, the melted resin of the film 2 is absorbed into the porous support 3 to prevent the openings 7 from clogging.

る。Comparative Example 2 Instead of carnauba wax in Example 2,
A heat-sensitive stencil paper was prepared by coating a base paper sheet with a methanol solution of 8% solids content of ethylene bis stearamide (melting point 145°C) at a dry coating amount of 0.8 g/m 2 and drying. When this base paper was printed using the same equipment as in Example 1, no ink bleeding was observed on the porous support, but the characters printed on the printing paper were extremely difficult to read. It was hot. The reason for this is thought to be that because the melting point of the ethylene bis stearamide is as high as 145°C, it is not sufficiently melted during plate making, impairing the ability of the porous support to absorb the film resin.

優れた効果を奏する。 As detailed above, according to the present invention, ink bleeding on the porous support is prevented by impregnating the porous support with wax or oil that is solid at room temperature and melts by the heat of the thermal head. This provides an excellent effect in that clear printed matter can be obtained.
