Abstract
Provided is a scale-shaped filmy fines dispersion. More specifically, scale-shaped filmy fines are subjected to a treatment for keeping the scale-shaped filmy fines from easily settling out. In the case of a metallic pigment using the scale-shaped filmy fines, the scale-shaped filmy fines are dispersed in the ink. As a result, nozzle clogging can be prevented, and the obtained print can achieve abundant metallic luster. The scale-shaped filmy fines dispersion contains, in a solvent, scale-shaped filmy fines obtained by finely grinding a simple metal, an alloy, or a metal compound. The scale-shaped filmy fines have a mean length of 0.5 μm or more and 5.0 μm or less, a maximum length of 10 μm or less, a mean thickness of 5 nm or more and 100 nm or less, and an aspect ratio of 20 or more.
