Title: Seishiro Ito: Innovator in Electrophoretic Coloring Technologies
Introduction
Seishiro Ito is a notable inventor based in Ikoma, Japan. He has made significant contributions to the field of electrophoretic coloring technologies, holding a total of 6 patents. His work focuses on developing advanced pigment dispersion compositions that enhance the coloration of aluminum and aluminum alloy oxide films.
Latest Patents
One of his latest patents is for an electrophoretic coloring composition. This innovative pigment dispersion composition is designed for fill-in coloration of aluminum or aluminum alloy oxide films. It comprises a pigment, a pigment dispersant, a water-soluble organic solvent, water, and a water-soluble amine or its derivative. The composition allows pigment particles to fill micropores of the aluminum oxide film deeply, resulting in a vivid color film with excellent weatherability and fastness. Additionally, it offers high adaptability for repetitive coloration, enabling easy washing away of pigment deposited on the film surface.
Another significant patent by Ito is a pigment dispersion composition aimed at depositing pigments into the pores of anodic oxide films formed on aluminum or aluminum alloy surfaces. This composition includes water, a pigment dispersant, and a pigment, with the pigment having a median particle size of not greater than 250 nm. This invention is particularly useful for coloration of anodic oxide films and boasts excellent repeated-coloration characteristics.
