Title: Innovations by Kei Etoh in Coating Technologies
Introduction
Kei Etoh is a notable inventor based in Tokyo, Japan, recognized for his contributions to the field of coating technologies. He holds three patents that showcase his innovative approach to microcapsule-containing oil-based coating liquids and related applications. His work has significant implications for various industries, particularly in printing and coating processes.
Latest Patents
Etoh's latest patents include a microcapsule-containing oil-based coating liquid, which comprises hydrophobic core material-containing microcapsule particles. These particles are dispersed individually in a state of primary particle within an oil varnish for ink use or a resin for coating use. The invention also details a solvent that has an affinity for both the varnish or resin and the surface of the microcapsule wall material. The preferred solvent is a lower divalent or multivalent alcohol. A preparative method utilizing vacuum distillation is proposed for creating this coating liquid. Additionally, a sheet, such as a duplicating sheet of paper coated with the oil-based coating liquid, is provided. This innovation allows for the conversion of a water-based microcapsule system into an oil-based one without coagulating the primary microcapsule particles, retaining the original strength and flexibility of the microcapsule wall material.
