Abstract:
The present invention relates to [1] a water-based ink for ink-jet printing containing titanium oxide (A) and a pigment dispersant (B), in which the pigment dispersant (B) contains a constitutional unit derived from an anionic group-containing monomer (a) and a constitutional unit derived from a polyalkylene glycol (meth)acrylate (b); an average molar number of addition of an alkyleneoxide in the polyalkylene glycol (meth)acrylate (b) is from 15 to 100; an acid value of the pigment dispersant (B) is from 100 to 400 mgKOH/g; and a content of the pigment dispersant (B) in the water-based ink is from 0.3 to 18 parts by mass on the basis of 100 parts by mass of the titanium oxide (A), and [2] an ink-jet printing method of ejecting the water-based ink described in the above item [1] onto a printing medium using an ink-jet printing apparatus to print characters or images on the printing medium. According to the present invention, there are provided a water-based ink for ink-jet printing which contains titanium oxide as a pigment, and is excellent in redispersibility, and an ink-jet printing method.

Claim (Index 15):
An ink-jet printing method of ejecting the water-based ink for ink-jet printing according to  claim 1  onto a printing medium using an ink-jet printing apparatus to print characters or images on the printing medium, the ink-jet printing apparatus being equipped with a dispersing means for dispersing the titanium oxide (A) in the water-based ink, said method comprising the following steps 1 and 2:\n Step 1: redispersing the water-based ink by the dispersing means; and \n Step 2: ejecting the water-based ink redispersed in the step 1 onto the printing medium to print characters or images on the printing medium.
