Latest Patents

One of his latest patents is a method for hydraulic transfer printing. This method involves floating a transfer sheet made of a polyvinyl alcohol polymer film on the surface of an aqueous solution. The print layer is directed upward, and an article is pressed against the surface to transfer the print layer. The surface tension of the aqueous solution is adjusted to 45 mN/m or less, and the extension ratio of the transfer sheet is kept to 1.30 or less. This innovative approach allows for the transfer of high-definition print patterns onto articles with irregularities or curved surfaces. Another significant patent involves a polyvinyl alcohol film that is cast on a drum. This film has a thickness variance of 0.5 µm/mm or less, a thickness range of 20 to 150 µm, and a width of at least 2 m.
