Title: Thermal stencil paper and production thereof
Inventor: HATTORI EIJI
IPC: B41N1/24
Filed: 1987-12-11
Abstract: PURPOSE:To solve problems such as difficulties in control, lowering in sensitivity by a solvent and generation of curling, ensure favorable sensitivity and contrive higher durability to repeated printing, by using an epoxy resin as an adhesive for lamination. CONSTITUTION:An epoxy resin is used as an adhesive for lamination, in a thermal stencil paper obtained by laminating a heat-shrinkable plastic film with an ink-permeable base. Particularly, an epoxy resin with a polyamide resin as a hardener enables adhesion even when being used in a small quantity, enables easy control of the crosslinking degree, and provides a stencil paper with favorable perforability, solvent resistance and durability to repeated printing, by controlling the crosslinking degree to a relatively low value. Particularly in the case of adhering by use of an alcoholic solution of the epoxy resin, the high surface tension enables easy concentration of the adhesive on the vicinity of points of adhesion of the base and the film, and favorable adhesion can be achieved by a small quantity of the adhesive. In addition, the solvent will not attack the plastic film to cause curling of the laminate or lowering in perforation sensitivity.
