Abstract: The invention provides an aqueous ink composition which contains at least (a) a glycol ether type water-soluble organic solvent, (b) an acetylene glycol type surfactant and (c) a pigment, wherein the pigment has a ratio (B/A) of its dissolution amount (B) in the ink liquid medium at 40° C. to its dissolution amount (A) in the ink liquid medium at 25° C. (A) of from 1 to 10.

Abstract: An ink-jet recording apparatus having an ink-jet recording head including pressure generating chambers communicatively connected to a nozzle opening and a reservoir, pressure generating member for pressurizing the pressure generating chambers, and a control device for applying drive signals to the pressure generating member. The control device applies drive signals to the pressure generating member. The drive signals contain signals corresponding to print data and signals which minutely vibrate the meniscus of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control device causes ejection of ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates the meniscuses of ink formed at the nozzle openings a preset period of time before or after the discharging of the ink droplets in a printing operation.

Abstract: A yellow ink composition and a magenta ink composition are provided which have good properties satisfying requirements for a color ink jet recording ink, particularly a requirement that the color ink composition is less likely to cause clogging of nozzles, and can realize a printed image having excellent tone, waterfastness, storage stability, and lightfastness. Further, a color ink set comprising the above ink compositions in combination with a particular cyan ink composition and a particular black ink composition are also provided. A yellow ink composition comprising a dye represented by the following formula (XI) in combination with a dye represented by the following formula (XII) is a fundamental color ink composition: ##STR1## wherein R.sup.101 and R.sup.102 represent phenyl or naphthyl substituted by a hydroxyl group, --SO.sub.3 M, or --COOM.

Abstract: Two intermediate transfer ink jet recording methods and a recording device suitable for practicing the methods and an ink composition for use in the methods are disclosed. The first recording method comprises forming jetting an ink composition containing a thermoplastic resin on an intermediate transfer drum to form an ink image, heating the ink image to at least the softening or melting temperature of the thermoplastic resin to bring the ink image to a film form and then transferring the ink image to recording paper. The second recording method comprises jetting an ink composition containing a thermoplastic resin on an intermediate transfer drum to form an ink image, heating the ink image to form a concentrated ink image, transferring the concentrated ink image to recording paper and then heating the transferred ink image to at least the softening or melting temperature of the thermoplastic resin.

Abstract: A yellow ink composition, a magenta ink composition and cyan ink composition and a solvent system which are suitable for a color ink jet printing method are disclosed. These ink compositions can realize ideal color tones without limitation of properties of paper. Moreover, these ink compositions are excellent in intermittent jetting stability. The color ink jet printing method is also disclosed. In this method, ink compositions are overprinted to mix colors. Colors obtained by the color mixing have an ideal color tone.
