摘要： An image forming method comprises a step of reacting an ink containing a coloring material with a liquid composition containing fine particles reactive to the coloring material on a recording medium, where the reaction between the coloring material and the fine particles occurs in a liquid, the coloring material is adsorbed on the surfaces of the fine particles while keeping the monomolecular state as in the ink, and the fine particles having the coloring material on the surface aggregate each other. This method can provide images of high optical density and high color saturation, with less occurrence of white stripes in the image.

摘要： This invention relates to an ink set which can form a colored area on a recording medium with a broad color reproduction range, excellent uniformity of the colors, with effective prevention of bleeding at the boundary between adjacent different color areas on a recording medium, and high rub-off resistance of the colored area. The ink set has separately an aqueous anionic or cationic ink containing a coloring material, and a liquid composition containing fine particles dispersed therein and electrically charged at the surface in a polarity opposite to the ink. The ink and the liquid composition are adjusted to give, when mixed at a mixing weight ratio of about 1:1, a pH of the liquid mixture to cause aggregation of at least the coloring material.

摘要： An ink is provided which is capable of forming a recorded image with improved water resistance and improved ozone resistance of recorded images which are not achievable by conventional aqueous inks employing a water-soluble dye as the coloring agent, and also capable of forming images having improved fixability, improved color developability, and improved ozone resistance which are not achievable by conventional dispersion type inks employing a pigment as the coloring agent. The ink is useful widely for recording like ink-jet recording, and gives recorded images having high rub resistance and high ozone resistance and being excellent in color development and image transparency. The aqueous ink comprises a colored resin dispersed therein, and the colored resin is composed of a film-forming resin and a colorant dispersed in a monomolecular state in the film-forming resin.
