  • Patent number: 11001088
    Abstract: In one or more embodiments, the present invention provides a method of applying or printing structural colors to a substrate that involves pre-treatment of the substrate surface to prevent absorption of the fluid containing the particles. This allows the fluid to maintain their sessile drop shapes and as the water evaporates, the colloidal particles spontaneously assemble within the confined geometry into semi-ordered structures that interact with light to produce structural color. While the pre-treatment may be done in a variety of ways, application of a, hydrophobic and/or oleophobic coating, like 1H-IH,2H-perfluoro-1-dodecene (C10F21—CH?CH2) (perfluoro) monomer, fluoroalkyls, fluorohydroalkyls, cyclo-fluoroalkyls, fluorobenzen, by plasma-enhanced chemical vapor deposition (cold plasma treatment) has been found to be effective, particularly for printing applications. These treated substrates allow production of a wide range of structural colors using binary systems of nanoparticles.

  • Patent number: 10406796
    Abstract: Provided is a method for favorable bonding between an adherend and an adhesive body, which is capable of suppressing an ink layer, which is formed by an ultraviolet-curable ink, from being smudged while increasing convenience of a bonding operation between the adherend and the adhesive body, and the like. The method for bonding a medium to a foil body includes an ink layer formation process of spotting an ultraviolet-curable ink, which is ejected from an inkjet head, to a medium and irradiating ultraviolet ray to the ultraviolet-curable ink to cure the same, thereby forming an ink layer; a lamination process of laminating the medium and a foil body with the ink layer being sandwiched therebetween; and a bonding process of heating the ink layer, enabling the ink layer to function as an adhesive, and bonding the medium to the foil body.
