Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. A synthesis method according to claim 1 , further comprising performing ring-opening polymerization of the lactone-based compound subsequently to the ring-opening addition of the lactone-based compound. 3. A synthesis method according to claim 1 , wherein the functional group is represented by the following general formula (1): —(X) p —Y—(Z—COO) n M General formula (1) wherein, in the general formula (1), X represents the another atomic group; p represents a number of 0 or 1; Y represents an ester group; Z represents an alkylene group; n represents a number of 1 or more and 20 or less; and M represents a hydrogen atom, an alkali metal, ammonium, or an organic ammonium. 4. A synthesis method according to claim 3 , wherein Z in the general formula (1) represents C m H 2m , where m represents a number of 2 or more and 5 or less. 5. A synthesis method according to claim 4 , wherein m represents 5. 6. A self-dispersible pigment, which is synthesized by the synthesis method according to claim 1 .
