Document Type and Number:
WIPO Patent Application WO/2023/120521
Kind Code:
A1
Abstract:
Provided is a non-aqueous ink composition having high inkjet ejection stability even when a metal-containing brilliance pigment is contained therein. The non-aqueous ink composition, which is ejected by an inkjet method, contains an organic solvent and a brilliance pigment, wherein: the brilliance pigment contains a metal-containing brilliance pigment; a relationship among a volume-based cumulative 10% particle diameter (D10)(μm), a volume-based cumulative 50% particle diameter (D50)(μm), and a volume-based cumulative 90% particle diameter (D90)(μm) satisfies a relationship of expression (I); and the D90 is at most 5.0 μm. (1): (D90-D10)/D50≤2
