Oil-based magnetic ink |
abstract |
An oil-based magnetic ink can be provided that has low viscosity and improved storage stability. Specifically disclosed is an oil-based magnetic ink containing a magnetic pigment that contains a ferrite, a pigment dispersant A that has an acid value but has no base value, a pigment dispersant B that has an acid value and a base value, and a non-aqueous solvent. One example of the pigment dispersant A is at least one compound selected from the group consisting of hydroxystearic acid and polyhydroxystearic acid. One example of the pigment dispersant B has an acid value of at least 5 mgKOH/g. |
