  • Method of hydraulic transfer and hydraulic transfer base film
    Patent number: 8927061
    Abstract: In a method for hydraulic transfer printing, comprising floating a transfer sheet comprising a polyvinyl alcohol polymer film and a print layer formed thereon on a surface of an aqueous solution while directing the print layer upward, and then pressing an article against the surface of the aqueous solution to transfer the print layer to the article, wherein the surface tension of the aqueous solution is adjust to 45 mN/m or less and the extension ratio of the transfer sheet is adjusted to 1.30 or less during the transfer. This makes it possible to transfer a high-definition print pattern to the surface of an article having irregularities or a curved surface.
