| titleOfInvention | Pigment dispersant and its manufacturing method, pigment dispersion liquid for inkjet ink, and water-based inkjet ink |
| abstract | PROBLEM TO BE SOLVED: To provide a pigment dispersant capable of preparing a water-based pigment dispersion for inkjet ink, which has a highly finely dispersed pigment, excellent dispersion stability, and good resolubility. SOLUTION: This is a pigment dispersant used in a water-based pigment dispersion liquid for inkjet ink, and satisfies the following requirements (1) to (5). (1) An ABA block copolymer containing a structural unit derived from a methacrylic acid-based monomer. (2) The B chain contains a group represented by the following general formula (1) in the main chain and has an acid value of 30 mgKOH / g or less. (3) The two A chains contain a structural unit derived from methacrylic acid and a structural unit derived from methyl methacrylate or the like, respectively, and the total number average molecular weight is equal to or less than the number average molecular weight of the B chain. (4) The number average molecular weight is 5,500 to 25,000. (5) The carboxy group is neutralized and ionized. (R indicates an alkylene group or the like, and X and Y indicate O or NH) [Selection diagram] None |
