Title: Innovations of Atsuo Kobayashi
Introduction
Atsuo Kobayashi is a notable inventor based in Niiza, Japan. He has made significant contributions to the field of ink technology, particularly in the development of water-based inks for inkjet recording. With a total of 2 patents, his work focuses on improving the quality and efficiency of pigment dispersion in inks.
Latest Patents
Kobayashi's latest patents include a method for producing a water-based pigment dispersion liquid and a water-based ink for inkjet recording. This innovative method significantly reduces the number of coarse particles in the dispersion liquid, resulting in finer dispersed particles. The improved dispersion stability and storage stability enhance the discharge stability of the ink during use. His method involves kneading a mixture containing a quinacridone type pigment, a styrene-acrylic acid type copolymer, a basic compound, and a polyoxyalkylene glycol or its derivative. This process prepares a pigment dispersion that is solid at room temperature, which is then mixed with an aqueous medium to decrease viscosity and liquefy the dispersion.
Another patent focuses on a pigment dispersion that includes a bisacetoacetarylide pigment, a styrene-acrylic acid-based copolymer, a basic compound, and a wetting agent. The wetting agent contains at least one diol compound, selected from dipropylene glycol, 2-ethyl-1,3-hexanediol, and 1,2-hexanediol. The mass ratio of the diol compound to the pigment is carefully controlled to ensure optimal performance.
