PURPOSE:To improve adhesion among ink coloring materials and permit accurate superpositioning of colors by including surfactant at least as one of the ink raw material components to be contained in a heat fusion type ink. CONSTITUTION:As an ink raw material component at least surfactant is included. Surfactants to be recommended are fluorine series and/or silicone series compounds; and further, it is recommended that 0.05-0.6% of the above compound(s) should be contained. Pertaining to the quantities to be added, if superpositioned in the order of yellow, magenta and cyan, the surfactants to be added should be within the ranges of 0.05-0.1% for yellow 0.2-0.3% for magenta, 0.4-0.6 for cyan. If the quantities added are out of the above ranges, adhesion between any one of the ink coloring material and others would remarkably be reduced. Any of surfactants, as long as they are soluble mutually in other ink raw material components, may be used; however, Unidine as one of fluorine series, and dimethyl-silicone as one of silicone series, for instance, may be used. |
