Abstract

PURPOSE: To greatly increase the concentration of color at the time of high-speed recording by controlling the volume average grain size of a chromogenic agent at less than a specific value for a heat-sensitive recording sheet in which a heat-sensitve chromogenic layer containing a chromogenic agent and a developing agent is provided on a supporter.
CONSTITUTION: In a heat-sensitive recording sheet in which a heat-sensitive chromogenic layer containing an electron-donor colorless dye (as a chromogenic agent), e.g., 3-diethylamino-6-methyl-7-anilinofluoran, etc., and an electron-accepting compound (as a developing agent), e.g., 2,2'-bis(p-hydroxyphenylprropane), etc., is provided on a supporter, the volume avegarage grain size of the chromogenic agent is desgnated to 2.0 microns or less. Since the heat-sensitive recording sheet has good respondence to very short heat pulse at the time of high-speed recording, as compared with the case with a chromogenic agent of a coarse grain size, sufficient concentration of colors can be obtained by small heat energy.
