Abstract: PROBLEM TO BE SOLVED: To provide an image property of a high quality without void and unevenness in density on a black solid printed surface by a method wherein an average transmissivity when transmitted light is cast on a base paper, is a specified value or higher, and also, a promotion index is within a specified range. SOLUTION: A thermoplastic resin film and a porous supporting body may be bonded using an adhesive, or may be bonded without using adhesive. This base paper has an average trnsmissiovity when transmitted light is cast, of 50% or higher, and its is important that a formation index is within a range of 1-5. Preferably, the average transmissivity is 60% or higher, and the formation index is within a range of 2.0-5.0, and more preferably, the average transmissivity is 70% or higher, and the formation index is within a range of 2.0-5.0. When the average transmssivity is less than 50%, an ink transfer amount becomes insufficient, and only image of a low printing density are obtained, and it is not preferable. Also, when the formation index exceeds the range of 1-5, an ink passing becomes uneven, and void may occur on th printing. or an uneveness in the density becomes larger, and it is not preferable.

Abstract: PROBLEM TO BE SOLVED: To provide thermal screen printing stencil paper high in sensitivity and image quality and excellent in printing durability and wrinkle-proofing properties. SOLUTION: In thermal screen printing stencil paper obtained by laminating a polyester film and a porous support composed of polyester fibers without interposing an adhesive between both of them, the porous support is constituted of two or more kinds of layers containing fibers different in diameter and the orientation parameter of the film calculated by a laser Raman spectroscopic method is 3-10. This thermal screen printing stencil paper is produced by superposing two or more unstretched polyester fiber layers different in fiber diameter (5 μm) on an unstretched polyester fiber layers to co-stretch them.
