PIGMENT WITH THE SUPERIOR DISPERSION STABILITY INSIDE A DISPERSION MEDIUM, A MANUFACTURING METHOD THEREOF, A PIGMENT DISPERSANT, AND A YELLOW TONER

摘要

PURPOSE: A pigment, a manufacturing method thereof, a pigment dispersant, and a yellow toner are provided to disperse the pigment to a dispersion medium including an organic solvent without increasing the viscosity.;CONSTITUTION: A pigment includes a compound marked with chemical formula 1. The number average primary diameter of the pigment is 30~70 nanometers. A manufacturing method of the pigment includes the following steps: diazotizing a compound marked with chemical formula 2; coupling the outcome with a compound marked with chemical formula 3; and dry-heat processing the outcome in the temperature over 145 deg C.;COPYRIGHT KIPO 2011
