20090208679 | MATERIAL INTENDED FOR FORMING OR PRINTING IMAGES AND ITS MANUFACTURING METHOD - The present invention relates to a material intended for forming or printing images, comprising a support and at least one hydrophilic binder-based layer, and its manufacturing method, said method enabling the gelation process of the hydrophilic binder to be controlled. The material according to the invention is characterized in that in at least one of said hydrophilic binder-based layers, said hydrophilic binder is gelated by complexation with a complexing agent present on a heat-sensitive polymer or copolymer, that is hydrophobic at temperatures higher than its lower critical solution temperature LCST to protect the complexing agent, and water-soluble at temperatures less than its LCST to make the complexing agent accessible, the LCST of the heat-sensitive (co)polymer being higher than the setting temperature of said hydrophilic binder. The material according to the invention can be used as photographic material or as material taking aqueous ink compositions applied by the inkjet printing technique. | 08-20-2009 |
20090311448 | AQUEOUS COMPOSITION FOR RECORDING MEDIUM, AND INK-JET RECORDING MEDIUM USING THE SAME - The present invention provides an aqueous composition for recording medium in a form of aqueous dispersion solution comprising a polyvinyl alcohol-based resin (A) having an average saponification degree of 80-89 mol % and an average polymerization degree of 1700-3500, and containing a polyvinyl alcohol having 1,2-diol structural unit on a side chain thereof, represented by a general formula (1); an inorganic microparticle (B); and a boron compound (C). The aqueous composition of the present invention is not likely to become gel and therefore exhibit excellent preservation stability. Furthermore, the aqueous composition provides a recording layer serving as an ink receiving layer/glossy layer satisfied with gloss, ink absorbency, and water resistance. Accordingly, the present invention may also provide an ink-jet recording medium satisfying surface gloss by forming a coating layer of the inventive aqueous composition on a substrate, even when the substrate has water resistance. | 12-17-2009 |
20110059273 | INKJET RECORDING MEDIUM - The inkjet recording medium herein provided has at least: a support; and an ink-receiving layer provided on the support, the ink-receiving layer comprising inorganic fine particles, two polyvinyl alcohols having a degree of saponification different from each other, and a low molecular weight polyvinyl alcohol having an average degree of polymerization of 2000 or less. | 03-10-2011 |
20120148768 | TRANSPARENT INK-JET RECORDING FILMS, COMPOSITIONS, AND METHODS - Transparent ink-jet recording films, compositions, and methods are disclosed. These compositions and methods can impart excellent adhesion properties between film layers and the transparent support. The films have improved appearance compared to similar high optical density films. Such improved appearance films are produced without requiring reduced drying process throughput. These films are useful for medical imaging. | 06-14-2012 |
20140072734 | INDIRECT TRANSFER MEDIUM AND FORGERY PREVENTION MEDIUM PRODUCING APPARATUS - According to one embodiment, an indirect transfer medium includes: a base material; and an image receiving layer on which an image is capable of being formed by ink-jet printing. The image receiving layer includes a vinyl acetate maleate copolymer as thermo-adhesive material. The image receiving layer is laminated on the base material. | 03-13-2014 |
20140178609 | POLYOXYALKYLENE MODIFIED VINYL ALCOHOL-BASED POLYMER AND USE THEREOF - Provided is a polyoxyalkylene modified vinyl alcohol-based polymer comprising a polyoxyalkylene group in a side chain, wherein the polymer has a viscosity average degree of polymerization of not less than 150 and not more than 5000, a degree of saponification of not less than 40 mol % and not more than 99.99 mol %, and a polyoxyalkylene group modification rate of not less than 0.05 mol % and not more than 10 mol %; and the polyoxyalkylene group is composed of a polyoxypropylene block and a (poly)oxyethylene block and is represented by the following general formula (I). Such polymer is excellent in temperature-sensitive thickening properties. | 06-26-2014 |
20140302260 | WRISTBAND PAPER AND METHOD OF MANUFACTURING THE SAME - A wristband paper includes an ink-receiving layer formed on the upper side of the paper to be printed with ink, an adhesion layer and a separating layer for protecting the adhesion layer, which are formed on the lower side of the paper, wherein the ink-receiving layer is formed by applying a solution including polyethylene, polyvinyl alcohol and silica and then drying the solution. The wristband paper can be easily made into a wristband directly using a general printer. | 10-09-2014 |
