    摘要: Disclosed herein is an ink-jet printing method by ejecting an ink from an orifice of a printing head in accordance with a printing signal to conduct printing on a printing material, comprising using an ink having a pH value (pH.sub.A) at which the absorbance of the ink becomes a half of the absorbance at the pH in the stable region of the ink on an absorbance curve according to a pH change and a printing material comprising a base material and a coating layer provided thereon having a surface pH value of pH.sub.B, with pH.sub.A and pH.sub.B satisfying the relationshippH.sub.A
