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 1):
A water-based ink for ink-jet printing comprising titanium oxide (A) and a pigment dispersant (B), in which:\n the pigment dispersant (B) comprises 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 not less than 15 and not more than 100; an acid value of the pigment dispersant (B) is not less than 100 mgKOH/g and not more than 400 mgKOH/g; and a content of the pigment dispersant (B) in the water-based ink is not less than 0.3 part by mass and not more than 18 parts by mass on the basis of 100 parts by mass of the titanium oxide (A).
