摘要：There is provided a method for producing pigment crystals with sufficiently highpurity and sufficiently controlled crystal type, particle size, and aggregation propertyand dispersibility to obtain a pigment crystal that can be suitably used in both a solidphase and a liquid phase. The method for producing pigment crystals (S) from a pigmentprecursor (S) using retro Diels-Alder reaction, the method comprising producing thepigment crystals (S) from the pigment precursor (S) through a first displacementstructure (S) and a second displacement structure (S), which differ from the pigmentprecursor (S) and the pigment crystals (S) and also differ from at least from each other.
