摘要： An ink jet recording method using two liquids, i.e. a first liquid adapted to break a dispersed condition of a coloring agent in an ink composition, and containing a coloring-agent-component-coagulating reaction agent, and an ink composition, the method being capable of forming an excellent image. In this ink jet recording method wherein two-liquid printing is carried out, the first liquid is temporarily deposited on an intermediate transfer medium, and the resultant first liquid is then transferred to a recording medium. The ink composition is printed on the recording medium on which the first liquid has been transferred. An excellent image is thus obtained.
摘要翻译：一种使用两种液体的喷墨记录方法，即适用于破坏油墨组合物中着色剂分散状态的第一液体，并含有着色剂组分凝结反应剂，以及油墨组合物，该方法能够形成了良好的形象。在进行双液印刷的喷墨记录方法中，将第一液体暂时沉积在中间转印介质上，然后将所得第一液体转印到记录介质中。油墨组合物印刷在其上已转印有第一液体的记录介质上。因此获得了良好的图像。

摘要： Yellow, magenta and cyan ink compositions to be used in color ink-jet recording and a solvent system suitable for color ink compositions to be used in color ink-jet recording. These compositions reproduce ideal color tones irrespective of paper qualities and are excellent in intermittent delivery stability. Also disclosed is a color ink jet recording method using these compositions, wherein printing is performed by applying them one on another to mix various colors. The resultant color, too, has an ideal tone.

摘要： An ink-jet printing head used on the ink-jet printer, which is characterized in that a water-repellent layer (21) comprising a uniform layer of polymer including fluorine is formed on the surface of a nozzle from which ink is jetted. Said water-repellent layer can be formed to be solid and homogeneous by the use of polymer soluble in solvent and including fluorine, and thus an ink-jet printing head excellent in persistence of water-repellent characteristic and effect and durability is provided by a comparatively simple method.
