Abstract
The present invention relates to a liquid composition, an ink set employing the liquid compositions a method for forming a colored area of an image on a recording medium with the ink-set, and an ink-jet recording apparatus employing the ink set are provided, which enables formation of ink-jet record on a plain paper sheet with a broad color reproduction range, uniformity of the color, less stripy unevenness in a solid print part, and high rub-off resistance of the record. The liquid composition is stable in storage, and is ejected stably from the recording head.The liquid composition is used for forming a colored area on a recording medium by application with an anionic or cationic aqueous ink containing a coloring material, and the liquid composition contains fine particles dispersed therein and the surface of the fine particles being electrically charged in a polarity opposite to the aqueous ink.
