Abstract: PROBLEM TO BE SOLVED: To provide an ink for ink jet printing that has the following properties: (1) the increased resistance of the printed media to water; (2) the attainment of high adhesion of anionic ink; (3) the improved printing quality; (4) the effective action on the firm adhesion of ink and/or dye to the coated upper layer; (5) the reduced bleeding and (6) the combination of additional properties with pigment properties. SOLUTION: The objective ink for ink jet printing characteristically includes partially hydrophobic and/or wholly hydrophobic silicic acids.

Abstract: PROBLEM TO BE SOLVED: To obtain an ink mixture, especially, an ink jet ink having improved water resistance by using at least one silane or organosilicon compound. SOLUTION: The silane may be added to a precursor for producing a water- base ink mixture or to a finished water-base ink mixture. The silane may be added in a concentration of 0.1-15 wt.%, desirably, 0.5-2.5 wt.% to an ink composition. It is desirable that the silane used is octyltrimethoxysilane or hexadecyltrimethoxysilane. The silane may be used in the form of an aqueous emulsion. The ink mixture may be a water-containing and/or solvent-containing one. In order to improve the water resistance, it is possible to add hydrophobic silicic acid. The ink mixture is produced by adding an organosilane emulsion and optionally, pyrolytic hydrophobic silicon dioxide to a water-based pigment mixture optionally containing a surfactant.

Abstract: PROBLEM TO BE SOLVED: To provide a printing medium coating good in quality of printing, having water resistance and rapid in printing speed. SOLUTION: This printing medium coating is obtained by binding at least one component of the ink to at least one component of a medium coating material by a chemical bond.

Abstract: PROBLEM TO BE SOLVED: To obtain silicon dioxide which can be easily dispersed in a polar solvent by doping silicon dioxide produced by a flame oxidation method or flame hydrolysis with aluminum oxide by using an aerosol. SOLUTION: As for the doping component, a suspension liquid of aluminum salts or metal aluminum having 1×10-4 to 20 mass% is used to dope silicon dioxide with 1 to 10,000 ppm aluminum oxide. The BET specific surface area of the silicon dioxide after doped is 5 to 600 m2/g, and
