PROBLEM TO BE SOLVED: To provide both functions such as antisecrecy leakage and gloss- prevention and improve the efficiency of transferring a heat melting ink by forming an anchor layer of a resin and a dye and hueing a dye and the resin with the same color as an ink layer. SOLUTION: The resin to be used is of a polyester a polyolefin, an acrylic or a phenol type or is a copolymer of these resins. For the dye, either of disperse dye, basic dye, direct dye or sulfide dye is used alone or a mixture of two or more different types of dye are used. Especially the combination of mainly polyester resin and disperse dye is preferable. Further, the content of the dye in the anchor layer is preferably equivalent to the coloring saturation level or higher of the dye. In this case, the disperse dye is normally within the range of 80-250 pts.wt. based on 1000 pts.wt. of the polyester resin. The anchor layer is formed by applying a coating liquid obtained by dissolving the resin and the dye in an appropriate solvent to the surface of a base film and drying the coat. |
