Abstract
Provided is a synthesis method for a self-dispersible pigment, including performing ring-opening addition of a lactone-based compound to an acidic group bonded to a surface of a pigment particle directly or via another atomic group to bond a functional group including an ester group to the surface of the pigment particle.
Claims6
A synthesis method for a self-dispersible pigment, the method comprising performing ring-opening addition of a lactone ring of a lactone-based compound to an acidic group that is bonded to a surface of a pigment particle directly or via another atomic group, to bond a functional group, including an ester group, to the surface of the pigment particle.
