    Abstract: The present invention relates to a water-based ink for ink-jet printing which not only satisfies a high optical density but also exhibits an excellent high lighter-fastness; and a water dispersion used for the water-based ink. There are provided a water dispersion for ink-jet printing containing (A) a pigment and (B) water-insoluble polymer particles produced by polymerizing an ethylenically unsaturated monomer containing 25 to 85% by weight of an aromatic group-containing monomer in the presence of a reactive surfactant; and a water-based ink containing the water dispersion.

    Abstract: An amphoteric porous particulate comprising a basic polysaccharide and a polymer of an organic acid containing a reactive vinyl group or a salt thereof and having an average particle size of 50 mu m or less, which is capable of adsorbing a large amount of an acid or a base that is stronger than the acid or basic groups thereof and which is useful as a deodorant, a cosmetic or the like. The amphoteric porous particulate is obtained by emulsifying or suspending an aqueous solution containing a basic polysaccharide and an organic acid having a reactive vinyl group in a hydrophobic solvent and thereafter effecting polymerization thereof. A deodorant comprising a chitosan particulate having an average particle size of 0.01 to 50 mu m as a deodorant. A chitosan particulate having an available amino group content of 1.0 x 10 to 1.0 x 10 mol/g and a specific surface area of 10 to 300 m /g is particularly useful. A polysiloxane having long-chain alkyl groups and a melting point of 20 DEG C or above is useful as an oil component of a deodorant.

    Abstract: Disclosed are (1) an aqueous dispersion for inkjet recording, (2) an aqueous ink containing such an aqueous dispersion, and (3) a method for suppressing adhesion of agglomerates onto the inner surface of a nozzle of an inkjet head. The aqueous dispersion for inkjet recording contains a self-dispersible pigment (A) having a salt-forming group, and a polymer particle (B) having a constitutional unit derived from a salt-forming group-containing monomer and another constitutional unit derived from a silicone macromer, and the polymer particle (B) has the same salt-forming group as the self-dispersible pigment (A). This aqueous dispersion for inkjet recording is excellent in print density, marker resistance and ejection properties.
