か可能な溶融粘度を持っている必要かある。(Invention or problem to be solved l & i) In order to manufacture thermal transfer ink ribbons and thermal ink rolls, it is necessary to coat such heat-melting ink on sheets of paper or paper, or to impregnate open foam. Therefore, hot-melt inks must have a melt viscosity that allows coating or impregnation.

ールが要望されている。By the way, when printing with a thermal transfer ribbon or thermal ink roll is rubbed with a finger, it becomes dirty and unclear, and when heat is applied with an iron, etc., the printing becomes unclear or may be transferred to other places. In the market, there are thermal transfer ribbons and thermal ink rolls that do not smudge when rubbed with barcode readers or fingers, or that do not melt and transfer to other areas even when heated with an iron. It is requested.

た場合には、一般に鮮明な印字か得られない。In order to strengthen the adhesive strength and heat resistance of heat-melt ink, it is necessary to increase the amount of base polymer blended, but as mentioned above, heat-melt ink has certain limits on melt viscosity. However, it was not possible to incorporate a large amount of base polymer. Furthermore, even if a thermal transfer ink ribbon or a thermal ink roll using a heat-melting ink containing a large amount of base polymer could be manufactured, clear printing would generally not be obtained when such ribbons and thermal ink rolls were used.
