METHOD FOR MEASURING POROUS PHYSICAL PROPERTIES CAUSED BY LIQUID COMPOSITION, LIQUID COMPOSITION, INK SET, METHOD FOR FORMING COLORED PART ON MEDIUM TO BE RECORDED, AND INK JET RECORDER
PROBLEM TO BE SOLVED: To provide a method for measuring a physical property value caused by a liquid composition capable of obtaining an ink jet recorded matter of high quality particularly having excellent color developability, the liquid composition, an ink set, a method for forming a colored part on a medium to be recorded and an ink jet recorder. SOLUTION: The method for measuring the liquid composition comprises the steps of pretreating the composition containing at least fine particles by the steps of (1) drying the composition at 120 deg.C for 10 hours in an atmosphere to substantially evaporate a solvent content to dry the composition; (2) raising the dried matter to 120 to 700 deg.C in 1 hour, then baking the matter at 700 deg.C for 3 hours; and (3) gradually returning the baked matter to the ambient temperature after baking and then powdering the baked matter, and then a step of vacuum degassing at 120 deg.C for 8 hours and measuring pore physical properties of a fine particle aggregate formed of the composition by a nitrogen adsorbing and desorbing method.
