Abstract: A reactive color ink that contains a metal ion and exhibits mutual reactivity with a black ink is applied in an area including a print area 1, which has been formed by applying the black ink on a recording medium, and an area surrounding the print area 1, a distance between an edge of the print area 1 and an outer edge of the surrounding area being up to four pixels. This ink application is performed so that a value at least equal to 0.01 is obtained from a calculation where (a metal ion concentration (% by weight) in the reactive color ink applied in the area including the print area 1 and the surrounding area) is multiplied by (a print duty (%) of the reactive color ink applied in the area including the print area 1 and the surrounding area).

Abstract: The ink jet recording head 1 of the invention is provided with a black ink nozzle array Bkl for black ink constituting first ink, and plural color ink nozzle arrays C1 to C3 for discharging color inks. In a color ink nozzle array C1 having the shortest print distance from the black print formed by the black ink nozzle array Bkl, there is introduced a color ink showing the highest mutual reactivity with the black ink, and a color ink showing the next highest mutual reactivity is introduced into a nozzle array C2 having the next shortest print distance, and a color ink showing the lowest mutual reactivity is introduced into a nozzle array C3 having the longest print distance.

Abstract: The invention relates to a liquid composition measurement method. One embodiment of the method comprises the steps of: i) subjecting a liquid composition containing fine particles and a solvent to the following pretreatment steps (a) to (c) to form an agglomerate of fine particles: (a) evaporating the solvent of the liquid composition at 120 DEG C for 10 yours in atmosphere, and drying the liquid composition; (b) burning the dried liquid composition resulting from the pretreatment step (a) at 700 DEG C after raising temperature from 120 DEG C to 700 DEG C over one hour; (c) cooling a burned product obtained in the pretreatment step (b) to room temperature, powdering the burned product to obtain agglomerates of the fine particle; and ii) vacuum degassing the agglomerates at 120 DEG C for 8 hours, and measuring physical properties of pores of the agglomerates by a nitrogen adsorption and desorption method.

Abstract: The present invention relates to a liquid composition for use in forming a colored portion by imparting it together with an ink containing a colorant to a recording medium. The liquid composition includes at least a solvent and fine particles reactive with the colorant and, in which the fine particles in the liquid composition have an average particle diameter in a range of 30 to 200 nm, and a 10% cumulative value of scatting intensity of 10 nm or more and 90% cumulative value of scattering intensity of 300 nm or less, when measured by a dynamic light scattering method.

Abstract: 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.
