Abstract
A thermal recording paper having formed on a paper support a color generating layer containing a color former and a color developer that contacts the color former to generate a color, wherein the back side of the paper is treated with an inorganic salt, an anionic high molecular weight electrolyte, an electroconductive metallic compound, alumina sol, or silica sol, and has a surface electrical resistivity of not more than 5.times.10.sup.11 ohms at 25.degree. C. and 40% RH.
Claims1
A thermal recording paper comprising a color generating layer containing a color former and a color developer that contacts the color former to generate a color formed on a paper support, wherein the back side of the paper is treated with an inorganic salt, an anionic high molecular weight electrolyte, an electroconductive metallic compound, alumina sol, or silica sol, and has a surface electrical resistivity of from 1.times.10.sup.9 to 1.times.10.sup.11 ohms at 25.degree. C. and 40% RH.
