PURPOSE:To improve quality of a heat-sensing recording paper by eliminating sticking of dust, etc., to a head and unevenness of an entire black (or dark) image and also by providing it with better image-maintaining capability under the high- temperature and high-humidity condition in such a manner as to add a specific volume of fluoric alkyl system activating agnet to a heat-sensing component. CONSTITUTION:3-0.01wt% of fluoric alkyl system activating agent (such as perfluoroctane acid ammonium salt and perfluoroalkyl phosphoric acid ester, etc.) is added to a heat-sensing component containing a colorless pigment, such as leuco pigment, etc., an electron-receiving body which enables the pigment to generate color at the time when heated (such as organic acid and phenol system compound, etc.), is meltable sensitivity-increasing agent and a water-based adhesive. And, preferably, 5-0.1wt% of di-methylpolysiloxane water-based dispersed liquid is further added. And then, by coating thus prepared compound on a base paper and drying it, a heat-sensing recording paper of improved quality is obtained. |
