Abstract

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.

Currently, a sublimation N thermal transfer recording method is being considered as a method for obtaining hard copies from televisions, CRT color displays, color facsimiles, magnetic cameras, etc. Conventionally, this recording method used dyes for transfer printing of polyester fibers, but due to their low sublimation properties, the coloring power was poor, and it was not possible to obtain sufficient color density with the thermal energy of a normal thermal recording head. It was difficult.

It is possible to record the transcription of the degree of color acupuncture. Furthermore, since the dye of the present invention is a vivid cyan color, it is suitable for obtaining a full color by combining appropriate yellow and magenta dyes. Furthermore, since the light resistance is excellent compared to non-fl+, durable recording can be obtained.
