Scale-shaped filmy fines dispersion

A scale-shaped filmy fines dispersion to be used in a metallic pigment ink for an ink-jet printer, comprising, in a solvent, scale-shaped filmy fines obtained by finely grinding a simple metal, an alloy, or a metal compound, wherein:

• when one scale-shaped filmy fine among the scale-shaped filmy fines is observed in a substantially planar view and, with respect to the longest length value among lengths of the scale-shaped filmy fine from end to end, the mean value of the length values of all the scale-shaped filmy fines is regarded as a mean length, and
• when one scale-shaped filmy fine among the scale-shaped filmy fines is observed in a substantially side view and, with respect to the thickness value of the scale-shaped filmy fine, the mean value of the thickness values of all the scale-shaped filmy fines is regarded as a mean thickness, wherein
• the mean length is 0.5 μm or more and 5.0 μm or less,
• a maximum length is 10 μm or less when the maximum among the length values is regarded as the maximum length, and
• the mean thickness is at least 5 nm and is less than 15 nm.
