HEAT-SENSITIVE ORIGINAL PAPER FOR STENCIL PRINTING, STENCIL PRINTING PLATE, STENCIL PLATE-MAKING PRINTING METHOD, AND MULTI-COLOR STENTIL PLATE-MAKING PRINTING METHOD

摘要

PROBLEM TO BE SOLVED: To eliminate a picture quality reduction as time passes in a printing without spoiling a plate-making speed by containing at least an electromagnetic wave absorbing substance in an electromagnetic wave absorbing layer, and at the same time, containing a resin component. SOLUTION: For this heat-sensitive original paper for stencil printing, comprising at least an electromagnetic wave absorbing layer 101 and a thermoplastic resin film 102, at least an electromagnetic wave absorbing substance and a resin component are contained in the electromagnetic wave absorbing layer 101. When a condition that the content of the electromagnetic wave absorbing substance in the electromagnetic wave absorbing layer 101 is set at 20 wt.% or higher and less than 80 wt.% is satisfied, the mechanical strength is made favorable, and at the same time, the absorption rate for electromagnetic waves becomes sufficient, and a temperature ascent to melt both of the electromagnetic wave absorbing layer 101 and the thermoplastic resin film 102 can be obtained. Therefore, both of the prevention of a fracture due to a mechanical stress at the time of printing, and the formation of a clear perforation at the time of a plate-making can be achieved. As a result, a printed matter with a picture quality of a high grade can be obtained.
