  • Patent number: 10233343
    Abstract: An aqueous ink for use in an ink jet recording method in which ink is thermally ejected from a recording head to record an image on a recording medium. The aqueous ink includes zirconium oxide; a pigment; a resin dispersant for the pigment; and a first and a second urethane resin. The content (ppm) of the zirconium oxide in terms of zirconium is 0.5-20.0 ppm based on the total mass of the ink. The pigment is at least one of phthalocyanine, quinacridone, diketopyrrolopyrrole, dioxazine, perinone, perylene and anthraquinone pigments. Each of the first and second urethane resins has a unit derived from a polyether polyol. The ratio of the weight-average molecular weight Mw1 of the first urethane resin to the weight-average molecular weight Mw2 of the second urethane resin is 0.20-0.80 times. The second urethane resin has a weight-average molecular weight Mw2 of 20,000-70,000.

  • Publication number: 20080081848
    Abstract: A method of manufacturing super-absorbent polymer (SAP) which is powdery, insoluble in water, and able to absorb water, blood and urine with slight soluble substances. The method includes at least the following steps: mixing a monomer solution having at least 50 mol % of neutralized acrylic acid with polymerization initiators to synthesize a sticky precursor, wherein the monomer can be selected from acrylic acid, methacrylic acid, 2-acrylamido-2-methyl-propane sulfonic acid, or the mixtures thereof; mixing high hydrophilic epoxy compounds and polymerization initiators with the precursor and producing a gel via UV cross-linking; drying the gel at temperature of 100 to 250° C. to obtain a polymer; grinding and screening the polymer into constant particle size; coating the polymer with surface cross-linking agents; heating the polymer at temperature of 80 to 230° C.; and adding powdery inert inorganic salts into the polymer.

  • Patent number: 7312255
    Abstract: The invention relates to a mixture for the application of a polymeric coating to a substrate. Said mixtures comprises water and optionally an organic solvent, at least one water-dispersible radically polymerizable compound, at least one water-dispersible polymerizable crosslinking compound and at least one water-dispersible compound which forms free radicals upon exposure to actinic radiation. The radically polymerizable compound cannot fully set with the free radicals formed on irradiation at room temperature, but rather comprises further reactive bonds, which lead to further or complete setting with the crosslinking compound. The invention further relates to a method for application of a non-adhesive corrosion protection layer to a substrate, by application of a mixture to the surface of a metallic or polymeric substrate, drying the mixture and irradiation of the applied coating with actinic radiation of such an intensity and for such a period that a solid, hard, tough coating is formed.
