    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: Image-recording, hydrophilic colorants represented by the below-described formula (1) are disclosed. These colorants can be provided as colorants capable of forming images excellent in print quality such as chroma, gloss, density, light fastness and abrasion fastness, and also as hydrophilic colorants capable of affording inks excellent in physical properties such as long-term storability and press stability. [organic pigment]−[linking group]−[hydrophilic compound]  (1)wherein the [organic pigment] is a hydrophobic pigment having no hydrophilic group by itself, the [linking group] is a group linking the [organic pigment] and the [hydrophilic compound] with each other and blocking an effect of the [hydrophilic compound] on the [organic pigment], and the [hydrophilic compound] is an anionic, cationic and/or nonionic, hydrophilic compound.
