PROBLEM TO BE SOLVED: To provide an ink which is readable from outside, even if the collation marks for matching printed with the ink are hidden inside and unseen from outside, because they are superimposed and allows matching check based on the readings and does not impair the color of a colorant used, a toner and a developer used in electrophotography and a sheet using them. SOLUTION: The sheet has an X ray-detectable spot printed on a specific area of the sheet with an X ray-detectable printing ink in which a predetermined amount of X ray-detectable fine particles not impairing the color of a colorant used to the ink (solid) is added to the vehicle.

Abstract:
PROBLEM TO BE SOLVED: To provide a temperature control medium capable of efficiently controlling the temperature, by extremely reducing risk of damaging, by easily confirming a temperature history of an article in a box body without opening the box body, by indicating the highly accurate temperature history. SOLUTION: An emulsifying liquid 3 being liquid at the room temperature and coagulating when cooled to the predetermine temperature, is stored in a recess 5 provided in a casing 2 composed of a rigid body, and the opening part side of the recess 5 is sealed by a cover body 4. In this casing 2, a part forming a bottom part 2a of the recess 5 has a transparent part 6 for visually observing the emulsifying liquid 3 via the bottom part 2a. The emulsifying liquid 3 melts by a temperature rise, and separates in a phase. The temperature control medium 1 is formed with such a constitution. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an article for genuineness/falseness discriminating which can simply and certainly discriminate without irradiating it with light from outside and a genuineness/falseness discriminating device. SOLUTION: This article 10 for genuineness/falseness discriminating has a luminescent agent with a spontaneous luminescence function arranged in at least a part of a flat plate-like base 11. The luminescent agent starts spontaneous luminescene by applying an external force to regions 15, 16, 17 and 18, where the luminescent agent is arranged, of the base 11. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide ink for forming an ink-jet ink receiving layer on which yellowing of an ultraviolet cured type overcoat layer is inconspicuous even when this layer yellows in a curing reaction, and a sheet having an ink-jet ink receiving layer formed on a prescribed part of a sheet base by using the ink and further having an ultraviolet cured type overcoat layer formed on the receiving layer side. SOLUTION: The ink-jet ink receiving layer 3 is formed on the prescribed part of the sheet base 2 by using the ink for forming this layer, which contains a binder resin 4, porous particulates 5 and a fluorescent material as essential components, and the sheet 1 has further the ultraviolet cured type overcoat layer 7 formed on the receiving layer side.

Abstract:
PROBLEM TO BE SOLVED: To provide ink for forming an inkjet receiving layer, which has stable ink absorbency without depending on a difference between coloring agents (dyes) constituting printing ink to be used by an inkjet printer and which can produce inkjet-printed information having an excellent water resistance, an information carrying sheet, and an inkjet print forming method. SOLUTION: The ink for forming the inkjet receiving layer comprises at least microcapsules 1 containing a water repellent substance 2, and a hydrophilic solution 4 for dispersing the microcapsules 1. An ultraviolet curing type or penetrating and drying type solution is used as the hydrophilic solution 4. In the information carrying sheet 10, the inkjet receiving layer 12, which is formed by using the ink for forming the inkjet receiving layer, is arranged on a part or the whole of one side or both sides of a paper piece 11.

Abstract:
PROBLEM TO BE SOLVED: To provide an ink for forming an inkjet ink receiving layer with excellent hiding properties with which hiding information can not be seen through from the surface side and the back surface side of a sheet base on which the hiding information is formed by an inkjet printer using an inkjet ink, and to provide a sheet using it. SOLUTION: The ink for forming the inkjet ink receiving layer with excellent hiding performances in which a fine particle is compounded in a vehicle comprising a photocurable component and a photopolymerization initiator as main components, and a coloring material with a brightness L * of 0-50 is compounded so as to make a brightness L * of the inkjet ink receiving layer 3 of 30-90, is used. The inkjet ink receiving layer 3 is formed at a specified part of at least one face of a base sheet 1 by using this ink. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a thermosensitive recording sheet which can be used outdoors because of its outstanding weatherability, water resistance and water blocking resistance; can be printed out by a thermosensitive printer; inhibits the fading of an image or the yellowing of a texture part which occurs when exposed to light for a long time without a printing failure; and does not impair the thermal head of the printer even when a long-term recording operation is performed. SOLUTION: The thermosensitive recording sheet has a thermosensitive color developing layer formed of a thermosensitive color developing component, a photocatalyst and a thermosensitive color coupler containing a binder component formed at a specified area on the surface of a sheet base material and an overcoat layer formed on the thermosensitive color developing layer.

Abstract:
PROBLEM TO BE SOLVED: To provide a plastic card capable of being easily manufactured without causing trouble by a known card manufacturing process, having excellent embossing characteristics, causing no emboss cracking, inexpensive because an inexpensive PVC material can be used and widely used as a magnetic card, an IC card, a rewrite card or the like. SOLUTION: The plastic card 1 has a layered constitution wherein center cores 2A and 2B, oversheets 3A and 3B, a printing layer 4 and a protective layer 7 are laminated. The surface hardness of the printing layer 4 is set to 2B or below in pencil hardness. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet-curing ink which does not thicken or cure during storage and can be laminated on a sheet substrate to form an ultraviolet-curing ink layer curable by ultraviolet irradiation and to provide a sheet using the ink. SOLUTION: The ultraviolet-curing ink containing photopolymerization initiator microcapsules does not thicken or cure during storage. This ink is applied to a specified part of a sheet substrate to form a sheet with a ink layer laminated thereon. The ink layer can be cured by irradiating the microcapsules in the layer after collapsing them under applied pressure or after improving their permeability to the photopolymerization initiator under applied pressure, heat, or moisture instead of collapsing.

PROBLEM TO BE SOLVED: To provide an ultraviolet-curing release ink which does not thicken or cure during storage and can be laminated on a sheet substrate to form an ultraviolet-curing release ink layer curable by ultraviolet irradiation and to provide a release sheet using the ink. SOLUTION: The ultraviolet-curing release ink containing photopolymerization initiator microcapsules does not thicken or cure during storage. This ink is applied to a specified part of a sheet substrate to form a release sheet with a release ink layer laminated thereon. The release ink layer can be cured by irradiating the microcapsules in the layer after collapsing them under applied pressure or after improving their permeability to the photopolymerization initiator.
