Abstract: A process for preparing a carboxylic acid-based polymer comprising the steps of (A) a first polymerization reaction step comprising introducing an aqueous solution of monomers containing an alpha -unsaturated carboxylic acid or a salt thereof, an aqueous solution containing a hydrogensulfite, and a gas containing oxygen into a flow mixer to polymerize the monomers; and (B) a second polymerization reaction step comprising further polymerizing a reaction product containing the unreacted monomer obtained in the first polymerization reaction step. There can be stably and productively prepared a carboxylic acid-based polymer having a high quality with suppressed coloration and containing a reduced amount of impurities even if the amount of gas containing oxygen used in the initiation of the polymerization reaction is remarkably reduced.

Abstract: Provided are a water dispersion for ink-jet printing, wherein it is a water dispersion of water-insoluble graft polymer particles containing a colorant; the above graft polymer contains a principal chain having a constitutional unit derived from a vinyl base monomer and a side chain which is derived from a macromer containing an aromatic ring and having a polymerizable functional group at one end; both of the Log P values of the above principal chain and the above side chain are positive; and a difference between both falls in a specific range, and a water-based ink containing the same. The above water-based ink is excellent in a discharge stability, a storage stability, a heat stability and a water resistance.

Abstract: A water-based ink containing an aqueous dispersion of water-insoluble vinyl polymer particles containing a pigment, wherein the water-insoluble vinyl polymer is obtainable by copolymerizing a monomer mixture containing (a) a monomer having a salt-forming group, (b) a monomer having a long-chain alkyl group having 18 to 30 carbon atoms, (c) a macromer, (d) a monomer having a polyoxyalkylene group, and (e) a monomer copolymerizable with the monomer having a salt-forming group (a), the monomer having a long-chain alkyl group (b), the macromer (c) and the monomer having a polyoxyalkylene group (d). The water-based ink can be suitably used, for instance, as a water-based ink for inkjet recording and the like.

Abstract: A water dispersion for inkjet printing, which contains water-insoluble polymer particles containing a colorant. The content of the water-insoluble polymer in the water dispersion is from 1 to 7% by weight, and the surface tension of the water dispersion is 60 mN/m or higher at 20° C. A water-based ink for inkjet printing which contains the water dispersion produces printed images with a high optical density and a good color-to-color bleed resistance.

Abstract: There are provided a water-based ink for ink-jet printing which not only satisfies a high optical density but also is excellent in gloss and image clarity upon printing on a coated paper; a water dispersion used in the water-based ink; and a process for producing the water dispersion. The present invention relates to a water dispersion for ink-jet printing comprising colorant containing water-insoluble polymer particles which is obtainable by mixing at least two kinds of water-insoluble polymer particles (A) and (B) which are different in average particle size from each other, wherein said polymer particles (A) have an average particle size of 70 to 200 nm and said polymer particles (B) have an average particle size of 15 to 110 nm with the proviso that the average particle size of the polymer particles (A) is larger than that of the polymer particles (B), and a difference between the average particle sizes of the polymer particles (A) and (B) is 10 nm or more; a process for production of the water dispersion; and a water-based ink containing the water dispersion.
