METHOD OF PREPARING AGGLOMERATED FINE PARTICLES, LIQUID COMPOSITION, INK SET, METHOD FOR FORMING COLORED PORTION ON RECORDING MEDIUM, AND INK |
摘要 |
PURPOSE: Provided is a technique to obtain a color image excellent in color and color evenness. More particularly provided are a method of determining a liquid composition most suitable for the ink-jet recording technique, such a liquid composition, an ink set using such a liquid composition, a method for forming a colored portion on a recording medium and an ink-jet recording apparatus. CONSTITUTION: A process for measuring a liquid composition comprises the steps of: i) subjecting a liquid composition containing fine particles and a solvent to the following pretreatment steps (a) to (c): (a) evaporating the solvent of the liquid composition at 120 deg.C for 10 hours in atmosphere, and drying the liquid composition; (b) burning the dried liquid composition resulting from the pretreatment step (a) at 700 deg.C for three hours after raising temperature from 120 deg.C to 700 deg.C over one hour; (c) gradually cooling a burned product resulting from the pretreatment step (b) to room temperature, and 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.
