Latest Patents
One of Yoshimura's latest patents is for electrophotographic transfer paper. This invention features a coating layer on at least one side of the base paper, which includes a pigment and an adhesive agent. The adhesive contains a branched poly(meth)acrylamide copolymer with cationic and/or anionic groups, boasting a weight average molecular weight between 50,000 and 1,000,000. This electrophotographic transfer paper demonstrates superior high-speed throughput performance, making it ideal for high-speed copy machines and printers. Additionally, when a printability improver is included in the coating layer, it enhances ink adhesion and surface strength, which are essential for offset printing.
Another significant patent by Yoshimura is a process for producing cast-coated paper for inkjet recording. This method involves applying a coating solution containing a pigment and a binder resin to a base paper. A treatment solution is then applied to solidify the binder resin while the coating layer is still wet. The wet, solidified coating layer is pressed against a heated drum to create a cast-coated layer. This innovative approach utilizes the double pond method, ensuring effective treatment of the coating layer.
