Abstract: A pigment composition for a pigment contained in ink or the like is provided, the pigment composition being capable of better preventing oxidation of the pigment from occurring in the ink or after printing, and better reducing discoloration of the pigment, even when the pigment has a small particle size such as a nanometer size. Further, a tablet and a capsule are provided. For example, the pigment composition includes: a black iron oxide; a dispersion medium; a dispersant; and an oxidation inhibitor, wherein the black iron oxide has a median diameter D50 of 30 nm or greater and 1 μm or less, and the oxidation inhibitor is reduced isomaltulose.

Abstract: An edible aqueous inkjet ink and a tablet. The edible aqueous inkjet ink contains a relatively large amount of volatile alcohol, which has improved or even excellent transfer durability and reduces ink ejection failure. The tablet includes a portion printed with the edible aqueous inkjet ink. The edible aqueous inkjet ink according to the present embodiment includes food coloring, ethanol, and a surfactant which has a hydrophilic-lipophilic balance value (HLB) in a range of 16 or more and 20 or less. The food coloring may preferably be sodium copper chlorophyllin. The surfactant may preferably be a sucrose fatty acid ester.
