Abstract:
The present invention relates to an ink-jet printing method that is capable of obtaining good printed characters or images which are free of occurrence of white lines or streaks irrespective of irradiation with an active energy ray. The present invention provides an ink-jet printing method including the steps of ejecting at least one ink A selected from the group consisting of a black ink and chromatic inks onto a low-liquid absorbing printing medium and then ejecting a white ink thereonto, in which the ink A contains at least one pigment selected from the group consisting of a black pigment and chromatic pigments, and a polymer dispersant containing a constitutional unit derived from a polyalkylene glycol (meth)acrylate; and the white ink contains titanium oxide and a polymer dispersant containing a constitutional unit derived from a polyalkylene glycol (meth)acrylate.
