Abstract
A tissue paper used for heat sensitive stencil sheet to be used for a heat-sensitive stencil sheet comprising natural fibers, synthetic fibers, or their mixture, which being impregnated with an ionizing radiation curable type of resin, and a heat-sensitive stencil sheet having a thermoplastic resin film being bonded thereto, wherein, at surface of one side of the resin film, there is provided the tissue paper used for heat-sensitive stencil sheet, which is that being bonded the thermoplastic resin film by point-bonding with using an ionizing radiation-curable resin, and there is provided an anti-sticking layer on the other side of the thermoplastic resin film.
Claims12
A method of fabricating a heat-sensitive stencil sheet, said method comprising steps of:
- bonding a tissue paper on one side of a porous resin layer provided on a thermoplastic resin film, by point-bonding with an ionizing radiation-curable resin;
- and
- irradiating the point-bonded tissue paper with an electron beam thereby perfecting bonding between the issue paper and said one side of the porous resin layer provided on the thermoplastic resin film.
A method of fabricating a heat-sensitive stencil sheet, said method comprising steps of:
- applying an ionizing radiation-curable resin onto one side of a tissue paper;
- bonding the resin-applied side of the tissue paper to one side of a a porous resin layer provided on a thermoplastic resin film, by point-bonding with the ionizing radiation-curable resin;
- and
- irradiating the point-bonded tissue paper with an electron beam, thereby perfecting bonding between the tissue paper and said one side of the porous resin layer provided on the thermoplastic resin film.
