Abstract

This invention relates to heat-sensitive recording paper. More particularly, in heat-sensitive recording paper including a heat-sensitive recording layer containing a basic colorless dye and an acidic material causing coloration of the basic colorless dye upon heating on a substrate, the present invention relates to heat-sensitive recording paper wherein the support contains used paper and the content of the residual surfactant contained in the support is below 1,000 ppm. According to the present invention, heat-sensitive paper which is economical and has high storage stability and high reliability with respect to a thermal head can be obtained.
