Abstract: A water dispersion for inkjet printing which contains polymer particles containing a colorant. The polymer constituting the polymer particles is produced by the copolymerization of a monomer mixture in the presence of a-methylstyrene dimer. The water dispersion for inkjet printing and a water-based ink for inkjet printing containing the water dispersion exhibit excellent jetting properties and a high optical density.

Abstract: The invention relates to a process for producing a mixture of a pyran represented by the formula (II) and a hydroxypyran represented by the formula (III) by reacting aldehyde (I) with isoprenol. R 1 ―CHO (I) wherein R 1 represents an alkyl or alkenyl group having 1 to 12 carbon atoms, an optionally alkyl- or alkoxy-substituted aryl group having 6 to 12 carbon atoms in total, or the like. Further, the hydroxypyran compound in the resulting mixture is subjected to dehydration reaction in the presence of an acid to produce a pyran compound represented by the formula (II).

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: PCT No. PCT/JP95/01602 Sec. 371 Date Oct. 30, 1996 Sec. 102(e) Date Oct. 30, 1996 PCT Filed Aug. 10, 1995 PCT Pub. No. WO96/05234 PCT Pub. Date Feb. 22, 1996A process for producing an improved super absorbent polymer is disclosed. The process comprises adding to a water-retained super absorbent polymer retaining 10 to 100 parts by weight of water per 100 parts by weight of the super absorbent polymer, (a) a polyfunctional compound having two or more reactive groups and selected from a hydrophilic polymer or a metallic compound in an amount of 0.005 to 5 parts by weight per 100 parts by weight of the super absorbent polymer, and (b) a crosslinking agent having two or more functional groups capable of reacting with the polyfunctional compound at a weight ratio of the polyfunctional compound to the crosslinking agent of 0.1 to 30; mixing; and allowing the mixture to react by heating.
