发明名称 INK SET, AND INK MEDIA SET, INKJET RECORDING METHOD AND INKJET RECORDING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an ink set in which the equilibrium concerning moisture is completely coincident in the whole humidity range, interruption of ink jetting from a nozzle due to the clogging thereof etc., and the curved jetting of ink are prevented, and which has high reliability and hardly causes clogging, an ink media set, an inkjet recording method and an inkjet recording apparatus. <P>SOLUTION: The ink set is formed by combining at least two kinds of ink containing at least a coloring agent, a wetting agent and a resin, wherein each ink in the ink set contains at least one different kind of the wetting agent and the ratio of the difference between the maximum quantity of the whole wetting agent and the minimum quantity of the whole wetting agent to the maximum quantity and the ratio of the difference between the maximum content of the moisture remaining in the equilibrium under a temperature of 23&deg;C and humidity of 50% RH and the minimum content of the moisture to the maximum content are each equal to or below 5%. <P>COPYRIGHT: (C)2009,JPO&INPIT
