Method of measuring liquid composition, liquid composition, ink set, method for forming colored portion on recording medium, and ink-jet recording apparatus

摘要

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.
