Title: Michie Ishii: Innovator in Chemical Engineering
Introduction
Michie Ishii is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of chemical engineering, particularly in the development of novel compounds and methods. With a total of 3 patents to his name, Ishii continues to push the boundaries of innovation in his industry.
Latest Patents
Ishii's latest patents include a groundbreaking method for producing aromatic diisocyanate. This innovative method involves reacting a diamine compound with a chloroformate to create a urethane intermediate. Subsequently, the urethane intermediate is reacted with either a halogenated organosilicon compound or a halogenated organoboron compound, utilizing an organic solvent that can dissolve both the diamine compound and the urethane intermediate. This one-pot method results in an aromatic diisocyanate that exhibits exceptional heat resistance and chemical resistance. Another notable patent is a heat-resistant negative-working photoresist composition. This composition consists of a resin component containing a carbodiimide unit and a compound that can induce a basic compound upon irradiation with actinic rays. The resulting photosensitive layer demonstrates sufficient sensitivity even with lower irradiation energy, allowing for the creation of sharp negative-type patterns.
