Abstract:
An ink composition for ultraviolet curable ink-jet recording including carbon black, a photopolymerizable compound and a photopolymerization initiator, comprising at least one selected from the group consisting of non-metallic phthalocyanine sulfonic acids, metal phthalocyanine sulfonic acids in which the central metal is Cu, Fe, Ni, Co, or Ti, and metal salts thereof, and a polymer dispersant containing a basic functional group. The photopolymerizable compound may dissolve the polymer dispersant.
