Title: Innovations of Shoichi Endo
Introduction
Shoichi Endo is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of inkjet technology, holding a total of 5 patents. His work focuses on improving the quality and efficiency of inkjet recording mediums.
Latest Patents
One of his latest patents is for an inkjet recording medium. This invention involves forming a coating layer that contains a pigment and a binder on the surface of a base material. The coating layer is then pressed onto a heated mirror-finished surface to dry, creating an ink-absorbing layer through a cast coating method. The pigment used in this invention includes colloidal silica with a primary particle diameter ranging from 10 nm to 100 nm, while the ratio of the secondary particle diameter to the primary particle diameter is between 1.5 and 3.0.
Another significant patent by Endo is a process for producing cast-coated paper for inkjet recording. This method involves supplying a coating solution containing a pigment and a binder resin to a base paper. A treatment solution that solidifies the binder resin is applied to the wet coating layer. The wet, solidified coating layer is then brought into pressure contact with the mirror surface of a heated drum and dried to obtain a cast-coated layer. This innovative process utilizes the double pond method, where the roll is enclosed by the base paper to ensure effective contact with the wet coating layer.
