PURPOSE:To enable transfer with high image quality to be performed without being affected by the surface of a transfer recording paper, by incorporating a silicon surfactant for lowering the surface tension of a heat-fusible ink in a molten state, into the ink. CONSTITUTION:A silicon surfactant for lowering the surface tension of the heat-fusible ink in a molten state is incorporated into the ink. The mixing ratio of constituents of the ink is preferably so set that 100pts.wt. of the ink comprises 5-25pts.wt. of a coloring agent and 5-15pts.wt. of the surfactant, the balance being a binder. When the thermal recording medium 1 is used for recording, a thermal head 13 is driven to generate heat according to a recording signal, the heat-fusible ink layer 12 at the part of a base 11 making contact with the head 13 is melted, and the melted ink is transferred to projected parts of the transfer recording paper 14. Because the melted ink contains the surfactant, the surface tension thereof is lowered, and the ink flows into recessed parts of the paper 14, so that the printing of broken characters can be prevented from occurring. |
