PROBLEM TO BE SOLVED: To provide an aqueous white ink for an inkjet which uses titanium oxide as a pigment and has a low viscosity and excellent storage stability and pigment settling properties.SOLUTION: There is provided an aqueous white ink for an inkjet which comprises at least titanium oxide, a pigment dispersion resin, an organic solvent and water, wherein at least a resin obtained by copolymerization of an α-olefin and (anhydrous) maleic acid is used as the pigment dispersion resin. In addition, an α-olefin having 8 or more carbon atoms is preferably used as the α-olefin. A 1,2-alkanediol having 4 to 8 carbon atoms is contained as the organic solvent and the pigment dispersion resin has a polyalkylene glycol group. |
