发明名称 HEAT SENSITIVE STENCIL SHEET
摘要 <p>PURPOSE: A heat sensitive stencil sheet is provided to obtain a high-quality image free from white missing portions and inconsistencies in density even at high resolution. CONSTITUTION: A heat sensitive stencil sheet comprises: a thermoplastic resin film and a porous substrate permitting ink permeability, wherein a dispersion index of reflected light obtained by irradiating the substrate with light is at least 13, the dispersion index being defined as h/(L x 100) wherein h represents a maximum peak frequency in a histogram obtained by classifying the density of a reflected light image read on an area of (10 cm)¬2 with a 787-by-787-pixel resolution of 64 levels, and L is (highest level which exceeds 500 frequencies in the histogram) - (lowest level which exceeds 500 frequencies in the histogram) + 1.</p>
