Abstract
A heat-sensitive recording paper is disclosed. The paper is comprised of a support base, a nearly colorless electron donating dye contained in a dispersion on the base, an organic acid capable of producing a color upon contact with the dye, the organic acid contained in a dispersion on the base, and a phenol compound contained in a dispersion on the base, the phenol compound being represented by the general formula (I) defined within the application. By including the particularly disclosed phenol compound within the heat-sensitive recording paper it is possible to obtain a color image which does not fade when stored even in adverse conditions. Furthermore, the inclusion of the phenol compound does not increase fogging.
