Abstract

A thermal transfer recording apparatus is disclosed and includes a recording medium sheet formed of a plastic film material having numerous minute voids therein, and a thermal recording sheet formed of a heat resistive base sheet with opposing surfaces and a thermal transfer layer coated onto one of the opposing surfaces of the base sheet. The thermal transfer layer comprises an ink material containing a binder material and being transferable to the recording medium sheet, and particles which are solid at room temperature and are mixed into the transfer layer in order to form minute protrusions on a surface of the thermal transfer layer. The apparatus also includes a heater for raising the temperature of the thermal transfer layer in a controlled manner so as to decrease the viscosity of the thermal transfer layer. The recording medium sheet can, alternatively, be provided with a coated layer coated onto the surface of the plastic film and comprises a coated layer material, and particles which are solid at room temperature and have a diameter greater than the thickness of the coated layer material, so as to provide a roughened surface to the coated layer.
