摘要

PROBLEM TO BE SOLVED: To provide a dark powder dispersion having low saturation and showing a deep black color, a substrate with a colored layer, and a dark powder dispersion liquid for forming these. SOLUTION: The value of the mass ratio (mass of dark pigment / mass of composite tungsten oxide fine particles) of the dark pigment to the composite tungsten oxide particles is 0.01, which contains a dark pigment, composite tungsten oxide particles and a solvent. Provided is a dark-colored powder dispersion liquid having a mass ratio of 5 or less. [Selection diagram] None
