    摘要： Disclosed are an aqueous pigment dispersion containing at least a pigment, water, a high-molecular dispersant, and an alkali. The high-molecular dispersant is a diblock polymer having a formula (1) of A-B or a triblock polymer having a formula (2) of A-B-C. The diblock or triblock polymer is a diblock or triblock polymer obtained by polymerizing addition-polymerizable monomers with a radical generator while using an organic iodide as a polymerization initiating compound and an organic phosphorus compound, organic nitrogen compound or organic oxygen compound as a catalyst. Also disclosed are a production method and use of the aqueous pigment dispersion. With the high-molecular dispersant obtained by a simple living radical polymerization process free of the problems of conventional living radical polymerization and having a precisely-controlled molecular structure, the aqueous pigment dispersion can be obtained with the pigment dispersed in it.

    摘要： Disclosed is an emulsion binder containing an A-B block copolymer. The A-B block copolymer has a number average molecular weight of 5,000 to 100,000, and a polydispersity index (weight average molecular weight/number average molecular weight) of not greater than 1.7. The polymer block A has an acid value of 0 to 30 mgKOH/g and a glass transition point of not higher than 60° C. The polymer block B has an acid value of 75 to 250 mgKOH/g. The A-B block copolymer has been neutralized with an alkaline material, and has been allowed to self-emulsify in an aqueous medium to form emulsion particles having an average particle size of 30 to 300 nm.
