摘要： The present invention relates to [1] a process for producing pigment-containing modified polymer particles, including the step of reacting pigment-containing polymer particles (A) containing a functional group and a compound (B) containing a reactive group capable of reacting with the functional group of the polymer particles (A) in a medium under such a condition that a ratio [(B)/(A)] of total moles of the reactive group of the compound (B) to total moles of the functional group of the polymer particles (A) is from 0.10 to 0.62; [2] a pigment water dispersion including an aqueous medium and the modified polymer particles produced by the aforementioned process which are dispersed in the aqueous medium; and [3] an ink including the aforementioned pigment water dispersion and an organic solvent. The modified polymer particles are free from formation of coarse particles upon production of pigment particles, so that an ink obtained by using the modified polymer particles can be prevented from suffering from increase in viscosity thereof when the ink is being concentrated by evaporation of water from the ink, and is excellent in rub fastness when printed on a low-water absorbing recording medium.

摘要： The present invention relates to white fine particles from which a white ink that is capable of satisfying both of high hiding power and good bending resistance in a printed material can be obtained, and further relates to white fine particles from which an ink that is capable of satisfying not only excellent fixing properties even when printed on a non-liquid absorbing printing medium such as a resin film, but also suppression of increase in viscosity of the ink and at the same time good deinking properties at a high level can be obtained. The present invention provides [1] white fine particles containing titanium oxide and a polymer component with which the titanium oxide is encapsulated, in which a titanium atomic fraction of a surface of the respective white fine particles as measured at a photoelectron takeoff angle of 45° by X-ray photoelectron spectroscopy (XPS) is not more than 7 atomic%, [2] a water-based ink containing the aforementioned white fine particles, in which the titanium atomic fraction of the surface of the respective white fine particles as measured at a photoelectron takeoff angle of 45° by XPS is not more than 5 atomic%, and [3] a process for producing a dispersion of white fine particles, including step 1 of mixing titanium oxide and a polymer dispersant to obtain a titanium oxide dispersion and step 2 of adding a polymerizable monomer to the thus obtained titanium oxide dispersion to subject the polymerizable monomer to polymerization reaction, thereby obtaining the dispersion of the white fine particles, in which a titanium atomic fraction of a surface of the respective white fine particles as measured at a photoelectron takeoff angle of 45° by XPS is not more than 7 atomic%.
