| 65 | Pigment for thermosensitive transfer recording | JP10338583 | 1983-06-09 | JPS59227490A | 1984-12-20 | NIWA TOSHIO; MURATA YUUKICHI; HIROTA TAKAO |
| PURPOSE:To obtain a sufficient color density with no large heat energy burden on a thermosensitive recording head by employing a specified material as pigment for thermosensitive transfer recording. CONSTITUTION:A pigment as shown by the formula (where, R and R' each represent methyl group, ethyl group or straight chain or branched chain propyl group or butyl group) is used for thermosensitive transfer recording. To form an ink for thermosensitive transfer recording using said pigment, the pigment is mixed into an appropriate resin, solvent, water or the like. A cyan-based pigment used in this invention is so large in the coloring capacity with an exceptionally better sublimating property to enable the transfer recording at a practically sufficient color density with no large burden on a thermosensitive recording head. As the pigment is the clear cyan color, it is ideal for obtaining a full color in the combination with proper yellow and magenta pigments. In addition, an excellent photoresistance enables a durable recording. | ||||||
