<p>PURPOSE:To provide the titled ink composed of a specific dye, an aliphatic hydrocarbon, and a liquid fatty acid inert to a resin, storable stably for a long period, usable without causing the clogging of the recording nozzle nor the generation of bubbles, having quick drying property and low viscosity, and useful for the recording head made of polysulfone resin, etc. CONSTITUTION:The titled ink having a viscosity of <=10CP is produced by compounding (A) an oil-soluble dye, (B) preferably 5-30wt% liquid fatty acid (e.g. oleic acid) inert to an amorphous thermoplastic resin and (C) preferably 60-70% 8-13C aliphatic hydrocarbon (e.g. n-dodecane).</p> |
