BRILLIANT INK AND IMAGE FORMATION DEVICE

Japanese Patent JP2022087029

A

To provide brilliant ink having high glossiness and adhesion.SOLUTION: Brilliant ink contains a brilliant pigment, resin particles and an organic solvent, in which particle size distribution of the resin particles measured by a dynamic light scattering type particle size distribution measurement device has peaks of two or more particle numbers, when in the peaks of the two or more particle numbers, a minimum particle size in the particle sizes corresponding to the apexes of the peaks is represented by a, a maximum particle size in the particle sizes corresponding to the apexes of the peaks is represented by b, and a particle size corresponding to the apexes of the peaks of the largest particle numbers in the particle size distribution of the brilliant pigment measured by the dynamic light scattering type particle size distribution measurement device is represented by c, a relation of a≤c≤b (where, a
