Claim Text:
1. A production process for a self-dispersible pigment, the process comprising a step of bonding a functional group containing a hydrophilic group to a particle surface of a pigment by causing at least one treatment agent selected from the group consisting of a compound represented by the following general formula (1), a compound represented by the following general formula (2), and a compound represented by the following general formula (3) to react with the particle surface of the pigment: wherein R 1 is (1) a cyano group or (2) an atomic group, the atomic group having (i) at least one group selected from the group consisting of an ester group, an ether group, a thioether group, a ketone group, and a sulfonyl group, and (ii) a group having at least one of an aliphatic group and an aromatic group, and the at least one group (i) is bonded to an azo group and the group (ii) is bonded to the at least one group (i), such that the group (ii) is bonded through the at least one group (i) to the azo group, and R 2 is a group (a) having at least one of an aliphatic group and an aromatic group, and (b) being substituted with at least one hydrophilic group selected from the group consisting of a carboxylic acid group, a sulfonic acid group, a phosphoric acid group, and a phosphonic acid group; wherein R wherein R
