PURPOSE:To obtain a new exfoliating paper for heat-sensing record, which has excellent thermal plasticity and thermal head-matching performance, by allowing a protective layer of water-soluble high molecular compound, which is laminated on a heat-sensing coloration layer, to contain therein a thermosetting resin filler. CONSTITUTION:A pressure-sensing bonding agent and an exfoliating material are laminated on one side of a supporting body, and the other side of the supporting body is provided with a heat-sensing coloration layer which contains thermal coloration substance, composed of colorless and light color leuco dyestuffs, and acidic substance allowing the coloration substance to color when heated, and also with a protective layer containing water-soluble high molecular compound (such as PVA, etc.) and thermosetting resin filler (such as, fillers of melamine resin and epoxy resin, etc.), and by making these laminations, the objective exfoliating paper is obtained. Further, as for the filler, it is desirable to choose powder ranging from 0.1mu to 10mu in particle size, and this used at the rate of 1-0.1times in weight of the water-soluble high molecular compound. |
