Abstract
An ultraviolet-curable white ink composition for ink jet recording is provided which has good dispersibility and good redispersibility and has excellent ejection stability, and provides excellent visibility of printed matter having a base material which forms a black or dark background. In an ultraviolet-curable ink composition for ink jet recording comprising titanium oxide, a polymeric dispersant having a basic functional group, a photopolymerizable compound and a photopolymerization initiator, the titanium oxide is surface-treated with silica and alumina and the weight of the silica, which coexists with the titanium oxide, is larger than that of the alumina.
