PURPOSE:To obtain a thermal transfer recording sheet with which a density of a printed image is easily adjustable by including upon a base film fine particles of plural kinds of heat fusion ink which include the same coloring agent and of different melting points. CONSTITUTION:A heat fusion ink layer of a thermal transfer recording sheet respectively includes a coloring agent of the same color and plural kinds of heat fusion ink of different melting points in a state of fine particles. By varying temperatures of a heat generating body the number of fine particles may be varied correspondingly to stages in accordance with the number of kinds of heat fusion ink, and the density of printed images may be varied correspondingly to the stages in accordance with the number of kinds of heat fusion ink. In the above instances, plural kinds of heat fusion ink are of fine particles of 0.5- 10mum of diameters, and the heat fusion ink layer is consisting of inclusion of plural kinds of fine particles. |
