PURPOSE:To enable reproduction in a thermal recording system directly utilizing video signal, by successively forming two layers of heat sensitive layers different in properties with respect to the adhesion of an ink and a m.p. or a sublimation point due to heat on a base. CONSTITUTION:A two-color stencil master 10 is obtained by successively forming a first heat sensitive layer 11 and a second heat sensitive layer 12 on a base layer 3. The base layer 13 is one obtained by impregnating condenser paper with polyvinyl alcohol or polyvinyl butyral and hydrophilic. The first heat sensitive layer 11 is prepared by mixing, for example, a black coloring matter in paraffin or silicone rubber and oleophilic. The second heat sensitive layer 12 is prepared by mixing, for example, a red coloring matter in acrylic resin and has oil repelling property and water repelling property. In addition, with respect to the second heat sensitive layer 2, the selction of resin is carried out so as to fluidize the same at about 60 deg.C. |
