Abstract: The present invention is directed to providing a retroreflective sheet for security that is difficult to be counterfeited, cannot be reused if once released, includes a printed image that can be identified visually regardless of an object to be attached such as a colored glass and also can be identified visually clearly even in the night time, and is directed to providing a method for manufacturing the same.

Abstract: An original sheet of a retroreflective sheet includes plural glass beads with a metal reflective layer provided on lower hemisphere surfaces thereof, a resin support sheet for supporting the glass beads, and a transparent cover film disposed on a surface side of the resin support sheet, wherein the resin support sheet and the cover film are connected to each other by heat press emboss forming from a rear face of the resin support sheet so as to form the original sheet of the retroreflective sheet, and a retroreflective sheet laminate includes a pressure-sensitive adhesive layer and a resin release film for covering the pressure-sensitive adhesive layer on a rear side of the original sheet of the retroreflective sheet.

Abstract: The retroreflective sheet of the present invention comprises a surface layer (1) including at least one layer, a focusing layer (2) containing glass spheres (3), and a metal reflective layer (4) on the back side of the focusing layer (2), wherein the glass spheres (3) are disposed at random locations in the thickness direction of the focusing layer (2). The external illumination system of the present invention comprises a sign having a sign face including the above-mentioned retroreflective sheet, and an external illumination source, and the distance from the illumination source to the sign face is within a range of at least 1 m and no more than 100 m. The present invention thereby provides a retroreflective sheet and an external illumination system with which wide-angle reflective performance with a wider incidence angle and observation angle can be ensured.

Abstract: The present invention is directed to providing a security sticker which is hard to be counterfeited, cannot be reused if being released and includes a printed image that is stable over a long period of time, and is directed to providing a method for manufacturing the same.

Abstract: An ink for ink jet recording includes water, a water-soluble organic solvent, a water-insoluble color material, a dispersant, and a compound expressed by the following chemical formula: R—O—(CH2CH2O)n—H ??(I) where R is an alkyl group having a carbon number of 25 to 150 and n is from 2 to 100. The ink not only can maintain performances such as storage stability and high-quality recording images, but also can effectively prevent nozzle clogging, exhibit good dispersion stability, and achieve a high redispersion property that ensures stable ejection both during long continuous operation and after stopping the operation for a long time.

Abstract: The hue variable retroreflective sheet of the present invention includes: a surface layer (1) composed of at least one layer; and a plurality of retroreflective elements (3, 4, 5) that are positioned beneath the surface layer, wherein the retroreflective elements (3, 4, 5) retroreflect incident light toward a light source direction, at least one layer of the surface layer (1) is an optical coherent layer that changes in color depending on a point of view, and in which an optical coherent coloring material with a core material having a surface that is covered with one or more substantially transparent coating layer is dispersed, and mirror-reflects the incident light toward a direction opposite to the light source side, at least one layer of the retroreflective sheet is a colored layer containing a coloring material that colors retroreflected light, and the retroreflected light and the mirror-reflected light provide different hues.

Abstract: A laminated body for printing with a temporary display layer is configured so that the temporary display layer capable of being peeled, which includes at least one layer capable of printing and displaying, and a substrate layer including at least one layer are laminated. A surface side of the temporary display layer that does not contact with the substrate layer has a property of absorbing ink that contains a sublimable dye and includes a resin composition that does not generate a blocking phenomenon during a heat treatment for sublimating the sublimable dye to diffuse into the substrate layer and to dye the substrate layer. This laminated body allows the dye in the temporary display layer to sublimate by the application of heat so as to print an image in the substrate layer. By peeling the temporary display layer, original display can be presented with excellent long term durability and dimensional stability against heat.

Abstract: A laminate for printing for coloring a resin layer by allowing a sublimable dyeing agent to permeate into the inside of the resin layer through heating, which comprises, in the order from the surface, a surface resin layer A(1) having a weak affinity with the sublimable dyeing agent and allowing the dyeing agent to pass through it and a coloring resin layer B(12) having strong affinity with the dyeing agent and preventing the transfer of the dyeing agent; and a printing method and a printed mater using the lamainate. The laminate for printing has, formed as an inner layer, a coloring resin layer having strong affinity with a sublimable dyeing agent and capable of preventing the transfer of the dyeing agent, which allows the prevention of the transfer of a sublimable dyeing agent having been printed.

Abstract: An ink for sublimation transfer ink jet recording includes water, at least one sugar alcohol containing not less than four OH groups, a sublimation dye, and a dispersant. The ink is printed on a sheet medium by ink jet printing, and then the sheet medium is heated to sublimate and transfer the sublimation dye onto an object to be dyed. The ink for ink jet recording and the sublimation transfer dyeing method using the ink not only can maintain performances such as storage stability and high-quality recording images, but also can reduce environmental pollution, effectively prevent nozzle clogging, and exhibit good dispersion stability.
