Abstract:
A compound that can improve azo pigment dispersibility in a non-water-soluble solvent. The compound is represented by formula (1): wherein R1 to R4 represent hydrogen or halogen; R5 to R9 represent hydrogen, COOR17 or CONR18R19, and at least one of R5 to R9 represents COOR17 or CONR18R19, where R17 to R19 represent hydrogen or an alkyl group having 1 to 3 carbons; R10 represents an alkyl group having 1 to 6 carbons or a phenyl group; R11 to R15 represent a hydrogen, L1R20 or L2R21R22, and at least one of R11 to R15 represents L1R20 or L2R21R22, where L1 represents a divalent linking group, L2 represents a trivalent linking group, and R20 to R22 represent an alkyl group having 8 or more carbons or an alkenyl group having 8 or more carbons; and R16 represents an alkyl group having 1 to 6 carbons or a phenyl group.
