  The present invention provides a method of forming an inkjet image, the method comprising: providing an inkjet recording ink comprising a colorless water-soluble planar compound having ten or more delocalized pi-electrons in one molecule; impacting a first droplet of the inkjet recording ink on a surface of an image receiving material; impacting a second droplet of the inkjet recording ink, within 50 milliseconds after the first droplet on the recording ink impacts on the surface of the image receiving material, on a surface of the image receiving material at a location where the second and the first droplet contact each other.

  本发明提供了一种形成喷墨图像的方法，该方法包括提供一种喷墨记录墨水，该墨水包含一种无色水溶性平面化合物，该化合物的一个分子中具有十个或十个以上的析出π电子；将喷墨记录墨水的第一液滴撞击到图像接收材料的表面上；在记录墨水上的第一液滴撞击到图像接收材料表面后的 50 毫秒内，将喷墨记录墨水的第二液滴撞击到图像接收材料表面上第二液滴和第一液滴相互接触的位置。

  It is an object of the present invention to provide an ink composition using a metal phthalocyanine type cyan dye, according to which the indoor storability (gas resistance) of images created using the ink composition can be improved. The present invention provides an ink composition containing water, metal phthalocyanine type cyan dye, and aromatic compound having a sulfo group and/or salt thereof represented by undermentioned general formula (1) and/or (2). Moreover, the present invention provides an ink jet recording method comprising carrying out recording by discharging droplets of an ink composition and attaching the droplets to a recording medium, wherein the ink jet recording method uses an ink composition as described above as the ink composition. Furthermore, the present invention provides a recorded article characterized by being obtained by recording using an ink composition as described above. (In the formula, M 1 represents a counter ion forming a salt, X represents an integer from 1 to 3, and R 1 and R 2 each represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, and R 1 and R 2 may be the same or different.) (In the formula, M 2 represents a counter ion forming a salt, Y represents an integer from 1 to 4, and R 3 and R 4 each represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, and R 3 and R 4 may be the same or different.)
