Title: Hajime Tsunoda: Innovator in Inkjet Technology
Introduction
Hajime Tsunoda is a notable inventor based in Ibaraki-ken, Japan. He has made significant contributions to the field of inkjet technology, holding 2 patents that showcase his innovative approach to ink formulation.
Latest Patents
His latest patents include an ink for inkjet printing and an ink for inkjet recording. The ink for inkjet printing comprises a pigment, a water-dispersible resin, water, and a water-soluble organic solvent. The water-dispersible resin is an anionic resin with a film elongation of 400-1,000%, a tensile strength of 20 to 50 N/mm, and an absolute value for the zeta potential (mV) of 40 or greater. The amount of the anionic resin, reported as a weight ratio relative to the pigment, is within a range from (0.5 to 2.5)/1, and the surface tension of the ink is maintained within a range from 30 to 50 mN/m. The ink for inkjet recording contains a vehicle, coloring agents, and a dispersing agent as required. The vehicle consists of a first solvent component with the lowest boiling point and a second solvent component with a higher boiling point. This innovative formulation ensures minimal penetration and bleeding when printed on non-coated papers, while effectively preventing clogging in the nozzles.
