Abstract
Thermal transfer recording is improved by a recording method involving providing a thermal transfer material having a support and an ink layer disposed thereon and which in turn includes a binder and a colorant. The binder includes 45-70 wt. % of an ethylene-vinyl acetate copolymer, 25-50 wt. % of a wax, and 7-12 wt. % of a tackifier based on a total weight of the binder. The ink layer has a breakdown strength of 30-80 kg/cm.sup.2 at 25.degree. C. The method also involves contacting an ink layer side of the thermal transfer material with a recording medium, supplying a pattern of energy from a recording head to the thermal transfer material, and separating the thermal transfer material from the recording medium to leave a transferred image on the recording medium. The thermal transfer material moves in a unit period of time by a first distance relative to the recording head which is smaller than a second distance through which the recording medium moves relative to the recording head in the same unit period of time.
