20090148787 | Method for fluorescent image formation, print produced thereby and thermal transfer sheet thereof - The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color. | 06-11-2009 |
20090219592 | FABRICATION PROCESS FOR CHOLESTERIC LIQUID CRYSTAL MEDIA HAVING A VOLUME HOLOGRAM - The invention provides a process capable of fabricating a cholesteric liquid crystal medium having a volume hologram with efficiency yet without recourse to complicated steps such as an alignment step. This is achievable as follows. A volume hologram layer is formed on a substrate, and a cholesteric liquid crystal layer is then formed on another substrate comprising a center substrate film that is subjected to bondable treatment. The volume hologram layer is applied to the center substrate film that is subjected to bondable treatment, and placed in a state where the volume hologram layer and cholesteric liquid crystal layer are laminated together via the substrate. The substrate is peeled off the volume hologram layer, and an adhesive layer is formed on the surface of the volume hologram layer off which the substrate is peeled off, followed by the provision of the substrate on the adhesive layer. Finally, the multilayer structure is shaped into a label form of cholesteric liquid crystal medium having a volume hologram layer. | 09-03-2009 |
