Document Type and Number:
Japanese Patent JP2017042731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersant which can stabilize dispersion of a dispersion liquid, which chiefly comprises a non-aqueous solvent and an organic solvent, at a high level.SOLUTION: A dispersant for dispersing a dispersoid in a disperse medium contains a copolymer having a first unit and a second unit, and fine particles. The first unit in the copolymer has a structure represented by formula (1), the second unit has a structure represented by formula (2), a ratio (s2/s1) between an average value s1 of a side chain length of the first unit and an average value s2 of a side chain length of the second unit is 1.0 or more and 4.0 or less, and the fine particle has a volume average particle of not less than 10 nm and not more than 500 nm and is insoluble in both of the disperse medium and the dispersoid.SELECTED DRAWING: None
