（特開昭61−246083号公報参照）。(Conventional technology and its problems) Conventionally, a black ink ribbon used for an impact dot printer is obtained by impregnating a liquid black ink in a base cloth, and a black ink coloring agent is usually carbon black. Black is used. However, the ink containing carbon black has a problem that the dot wire of the impact dot printer is remarkably worn, and therefore, the replacement of the dot wire must be performed more quickly than necessary. In order to improve such disadvantages, an ink using an organic pigment as a colorant has been proposed (see Japanese Patent Application Laid-Open No. 61-246083).
しかしながら、ここで使用されている有機顔料を組合
