    摘要： Disclosed is a heat-sensitive recording material which is excellent in color developing sensitivity, while having good storage properties such as heat resistance, moisture resistance and water resistance. Specifically disclosed is a heat-sensitive recording material wherein a heat-sensitive recording layer, which contains a colorless or pale-colored basic leuco dye and a developer for developing the color of the basic leuco dye, is formed on a supporting body. This heat-sensitive recording material is characterized in that the developer contains a first developer composed of a condensate represented by the general formula (I) below or a condensate composition, and a second developer other than the first developer, and the ratio of the first developer to the total amount of the developers is not less than 2% by weight but less than 50% by weight. (I) (In the formula, R represents a hydrogen atom, a halogen atom, a hydroxy group, a lower alkyl group, an alkoxyl group, a cyano group, a nitro group, an aryl group or an aralkyl group, and the m-number of R's may be the same as or different from one another; m represents an integer of 0-3; n represents an integer of 0-3; and X and Y independently represent a hydrogen atom, an alkyl group or an aryl group.)

    摘要： A thermosensitive recording medium containing a phenol derivative represented by the chemical formula 1 as the first color developing agent and a diphenyl sulfone derivative represented by the chemical formula 2 as the second color developing agent in the thermosensitive color developing layer was shown to have excellent color developing sensitivity, moist heat resistance, heat resistance, plasticizer resistance and the like.
    In addition, good bar code readability and color developing sensitivity were obtained when the concentration of the diphenyl sulfone derivative used as the second color developing agent to the color developing agent in the thermosensitive color developing layer was less than 50 wt.% (particularly when the concentration was 5 wt.% to 45 wt.% in the color developing agent). The effect was pronounced when the applied energy in the printed sample was 0.28 mJ/dot [sensitivity 2 (print density), plasticizer resistance 2]. Furthermore, good bar code readability was obtained when benzyloxy naphthalene (D-2), 1,2-di(3-methylphenoxy) ethane (D-3) and bis-paramethylbenzyl oxalate (D-4) were used in the sensitizer. In contrast, good moist heat resistance could not be obtained when a diphenyl sulfone derivative as the second color developing agent was not present.
