Title: Tateo Otsuki: Innovator in Binder Technology

Introduction

Tateo Otsuki is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of binder technology, particularly in the development of materials used in dry toners for electrophotography.

Latest Patents

Otsuki holds a patent for a binder for dry toners. This innovative binder comprises a copolymer resin created by reacting 10 to 50% by weight of a polyester resin with free carboxyl groups, whose acid value ranges from 10 to 100 and whose number-average molecular weight ranges from 1,000 to 5,000. The remaining 90 to 50% by weight consists of a mixture of a vinyl compound having a glycidyl group and another vinyl compound. The amount of the vinyl compound with a glycidyl group corresponds to the number of glycidyl groups equal to 0.25 to 1.5 times that of the carboxyl groups present in the polyester resin. This binder is essential for enhancing the performance of dry toners in electrophotography.
