The present invention provides a black
pigment dispersion. In the preparation of a
pigment dispersion liquid containing
perylene black, the dispersion liquid is prevented from gelling or the
viscosity of the dispersion liquid is prevented from changing during storage, and the dispersibility is improved. The black
pigment dispersion is used with
perylene black, any one of the derivatives shown by Chemical Formulas 1 to 3, and a dispersant that is a
copolymer composed of a
monomer A having the structure of
Chemical Formula 4, a
monomer B having a basic functional group, and a
monomer C capable of polymerizing with the monomer A and the monomer B, the monomer B is a monomer having a
nitrogen-containing aromatic heterocyclic group as a basic functional group and / or a monomer having the structure of
Chemical Formula 5, and the amine value of the dispersant is 120 mgKOH / g to 200 mgKOH / g. The content of
perylene black is 5
mass% to 25
mass%. The average particle
diameter of perylene black is preferably adjusted to 200 nm or less.
