| titleOfInvention | Quinophthalone sulfonic acid derivatives and pigment dispersions containing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a compound capable of finely and stably dispersing a quinophthalone-based pigment, and to further finely and stably disperse the quinophthalone-based pigment using the compound. Provided is a pigment dispersion having high color developability and good fluidity. SOLUTION: This quinophthalone sulfonic acid derivative has a structure corresponding to the following formula (1) when represented in the form of a free acid. Embedded image In the formula, R 1 and R 2 each independently represent an aliphatic or aromatic hydrocarbon group having 20 or less carbon atoms which may be substituted with a hydrocarbon group or a group other than the hydrocarbon group, Alternatively, they represent a heterocyclic structure in which both are bonded and which may further contain a hetero atom selected from nitrogen, oxygen and sulfur in R 1 and / or R 2 . X represents a hydrogen atom or a halogen atom. k is an integer of 1 to 6, m is 0.5 or more, and n is a number of 0 or more, and m + n is 1 or more. |
