Latest Patents
Misawa's latest patents include a method for producing a water-based pigment dispersion liquid and an inkjet recording water-based ink. The first patent presents a highly efficient method that significantly reduces the number of coarse particles in water-based pigment dispersion liquids. This method not only improves dispersion stability but also enhances storage stability and discharge stability when producing water-based inks for inkjet recording. The process involves kneading a mixture containing a quinacridone type pigment, a styrene-acrylic acid type copolymer, a basic compound, and a specific polyoxyalkylene glycol or its derivative. The resulting pigment dispersion is then mixed with an aqueous medium to decrease its viscosity.
The second patent details an inkjet recording water-based ink characterized by excellent long-term storage stability and ejection stability at higher pigment concentrations. This innovation ensures that the total content of polyvalent metals as impurities in the ink does not exceed 1.2 ppm in terms of 1 mass % of pigment concentration. The method for producing this ink involves a contact treatment with a specialized particulate chelating resin, which enhances the efficiency of production.
