    Abstract: PROBLEM TO BE SOLVED: To provide an ink for forming an ink jet ink accepting layer, which is excellent in ink jet ink absorbency and the water resistance of a printed ink, with which no bleeding develops in a printed image and, in addition, the location of the ink accepting layer of which can be confirmed, and a recording sheet employing the ink. SOLUTION: The ink for forming ink jet ink accepting layer mixed with a fluorescent substance is employed for an ink, which is prepared by mixing a vehicle mainly including a glycol-based solvent having the boiling point of 100 deg.C or higher or a vehicle mainly including an acryl-based photosetting component with at least fine porous particles or with further a cationic resin.

    Abstract: PROBLEM TO BE SOLVED: To provide an ink for forming an impress layer having excellent printing ink suitability, capable of printing at a necessary location of a base material having no impress property without hurting inherent property of the base material and forming an impress layer allowing impressing or stamp imprinting without blotting and having a formed impress layer not flaked off through an OCR reader, a thermal head or the like. SOLUTION: This ink for forming an impress layer comprises a cationic resin solution and porous fine particles added to a vehicle containing an acrylic photo-curable component as a main component, and this sheet has an impress layer 3 on a predetermined part of at least either surface of the base material 2 by using the ink and allowing impressing and stamp imprinting. This ink for forming an impress layer comprises 5-30 parts by mass of a cationic resin in the cationic resin solution and 20-50 parts by mass of porous fine particles based on 100 parts by mass of the vehicle.

    Abstract: PROBLEM TO BE SOLVED: To provide an ink for forming an impress layer excellent in suitability for printing ink, capable of forming the impress layer by printing enabling impressing and stamp imprinting without blotting on a required part of a base material conventionally lacking impress property without damaging original characters of the base, and the formed impress layer is free from peeling off by an OCR reader, a thermal head or the like. SOLUTION: This impress layer is formed on a predetermined part of at least one side of a base by using the ink for forming the impress layer obtained by formulating a cationic resin in an aqueous or a water dispersed form and porous particles to a vehicle comprising an acrylic photo-curable intergradient as a principal component.

    Abstract: PROBLEM TO BE SOLVED: To provide a new card for prevention of forgery such as a magnetic card, IC card and rewrite card which can not be easily forged by a color copying machine, personal computer, scanner, color printer or the like and which has a high forgery preventing effect. SOLUTION: The card for prevention of forgery is produced by disposing in the card at least one cholesteric liquid crystal thin film which can be observed from the outside of the card. The cholesteric liquid crystal thin film is formed by using ink containing a cholesteric liquid crystal compound by printing or the like.

    Abstract: PROBLEM TO BE SOLVED: To provide a scratch sheet having novel constitution employing a method incapable of discriminating the data applied to the surface of a sheet to be concealed from the surface thereof though a transparent film used in a coating layer removable by scratching. SOLUTION: Secret data is formed to the predetermined part on the surface of a sheet base material using a color changeable coloring matter composition reversely generating a hue change accompanied by the presence and absence of oxygen and covered with an oxygen impermeable transparent film.

    Abstract: PROBLEM TO BE SOLVED: To enhance the effect of deterring an alteration by varying the color of an antenna seeable from the outside. SOLUTION: An electrically conductive ink with a color-changing pigment added thereto is printed in an antenna pattern on a base film 4 to form the antenna 2. In particular, a base film 4 where an IC chip 3 is mounted on the antenna 2 is sandwiched by oversheets 7 and the portion 8 of each oversheet 7 corresponding to the antenna is made transparent to make the antenna 2 visible.

    Abstract: PROBLEM TO BE SOLVED: To increase the effect of deterring an alteration by providing a holographic display using an antenna which can be viewed from the outside. SOLUTION: A hologram is formed in a required position on a sheet metal 4 comprising a film with a conductive metal layer, to form the antenna 2 which uses the conductive metal layer as an antenna pattern. The sheet metal 4 where an IC chip 3 is mounted on the antenna 2, is sandwiched by oversheets 7, and at least the portion 8 of each oversheet 7 corresponding to the antenna is made transparent to render the antenna 2 visible.

    Abstract: PROBLEM TO BE SOLVED: To provide a new type sheet for preventing forgery which can do a simple and easy confirmation by a visible recognition and by an optical machine reading in judging whether it is real or not, has an excellent concealable property for a real thing-forgery judgment code, and has a difficulty to forge a sheet and to alter a real sheet. SOLUTION: A specific portion of the sheet is encoded for judging whether it is real or not by an ink including variable color composites whose tones vary reversibly depending on existence or non-existence of oxygen, and the tone of the portion is kept the same as one under oxygen existence circumstances.

    Abstract: PROBLEM TO BE SOLVED: To provide a new type sheet for preventing forgery which is low in cost and excellent in productivity, does not need to have a special device for making a real thing-forgery judgment code clear in judging whether it is real or not, can do a simple and easy confirmation by a visible recognition or by an optical machine reading, has a difficulty to forge a sheet and to alter a real sheet, and has an excellent concealing property for the real thing-forgery judgment code. SOLUTION: A specific portion of the sheet is encoded for judging whether it is real or not by an ink containing variable color composites whose tones vary reversibly depending on existence or non-existence of oxygen, and the portion is covered by a transparent film with oxygen impermeability to keep the same tone as one under non-oxygen circumstances.
