Abstract

PURPOSE:To enhance the clearness of the outlines of characters or patterns transferred through breaking a heat-fusible ink heated by a printing head along projecting parts of the surface of a base film, by providing the projecting parts on one side of the base film and applying the heat-fusible ink to the side provided with the projecting parts. CONSTITUTION:A multiplicity of recessed parts 25 and projected parts 26 are provided in the surface of a base film 24. A heat-fusible ink 20 is a solid ink obtained by mixing a pigment and a dye into a wax. Since a layer of the ink provided on the base film 24 is thinner at the projecting parts 26 than at the other parts by the height of the projecting parts 26 and the strength of the ink layer is accordingly lower at the projecting parts, the ink is broken along the projecting parts 26 of the base film when the ink is transferred onto a paper 19 by heat generating elements 21. The pitch of the projecting parts 26 is selected to be sufficiently smaller than the size of the smallest image of characters or patterns to be transferred. Therefore, the boundary lines of breakage substantially coincide with the boundary lines of the characters or patterns to be transferred, resulting in clear outlines. The shape of the recessed and projecting parts is hexagonal, rectangular, trapezoid, triangular or semicircular.

[Problems to be Solved by the Invention] In the conventional thermal transfer ink ribbon described above, the heat-melting ink (12) is attached to the heating element (
21) When the ink is melted by the heat and transferred onto the paper surface, as shown in FIG.
Because it is torn off during transfer, it breaks in a zigzag pattern. As a result, the outline of the image formed on the paper surface becomes unclear, resulting in a problem of deterioration of image quality. Furthermore, such deterioration in image quality becomes particularly noticeable when transferring to paper with a rough surface, which necessitates the use of expensive paper with a high surface smoothness.
