Abstract:
PROBLEM TO BE SOLVED: To realize the easy confirmation of the absence and presence of a falsification in an antifalsifying pressure sensitive reproducing sheet employing together with a back carbon. SOLUTION: A transfer sheet 2 and an accepting sheet 3 are piled up together. At the important positions in the opposing surface of a transfer sheet 2, a mixing layer 5 produced by mixing coloring agent microcapsules including a first coloring agent developing color different from the color developed in a back carbon ink described later and a developer is provided. Further, a back carbon ink layer 6 is provided in the accepting sheet side of the mixing layer 5. In the predetermined region opposing at least to the back carbon ink layer in the opposing surface of the accepting sheet, a coloring agent microcapsule layer 7 including a second coloring agent developing color different from the color developed in the back carbon ink is provided.

SOLUTION: A transfer sheet 2 and an accepting sheet 3 are piled up under the state that a developer layer is provided at the important positions in the opposing surface of a transfer sheet 2 and a mixing layer 6 produced by mixing a back carbon ink and a developer is provided at the accepting sheet 2 side of the developer layer 5. At the predetermined region opposing at least to the mixing layer 6 in the opposing surface of the accepting sheet 3, a coloring agent microcapsule layer 7 including a coloring agent developing color different from the color developed in the back carbon ink is provided.
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive composition having moderated peel ability and adherability of an adhesive layer coated on a substrate sheet and good in adhesiveness with a toner or an ink later written on the adhesive layer and to provide an information sheet having the adhesive layer of the pressure sensitive adhesive composition on an overlapped surface with the sub strate sheet. SOLUTION: This pressure sensitive adhesive composition is obtained by compounding a natural rubber adhesive base with silica particles which are a particulate filler having >=400 m2/g specific surface area and >=150 (mL/100 g) oil absorption volume in an amount of 5-40 pts.mass based on 100 pts.mass of the solid content of the adhesive base and is excellent in toner fixability.

PROBLEM TO BE SOLVED: To provide a forgery prevention light emitting card capable of preventing forgery and also easily verifying authenticity by providing the surface with a protective layer excellent in wear resistance, heat transfer suitability, brilliance and gloss on the surface, and to provide its manufacturing method. SOLUTION: This forgery prevention light emitting card is provided with the protective layer which contains ultraviolet-curable acrylate-based aqueous emulsion, vinyl chloride copolymer thermoplastic resin-based aqueous emulsion, ultraviolet illuminant and/or infrared illuminant as essential components and if formed by using a water-based coat agent containing a lubricant and a viscosity modifier as necessary. The water-based coat agent is applied on the outer surface of the card, then heated, dried and cured by ultraviolet irradiation, and the cured protective layer is heated and pressed to be formed.
Abstract:
PROBLEM TO BE SOLVED: To easily manufacture a magnetic card whose magnetic output is proper without damaging the protection function of a protection layer, the design property of a design printing layer and the shielding property of a magnetic layer shielding layer and without a trouble by making heat pressing for fixing a magnetic tape becoming a magnetic layer and the protection layer laminated on the tape to be minimum without using a solvent system material at the time of forming the protection layer and securely outputting magnetism from the magnetic layer. SOLUTION: A thin film being a protection layer is overlapped on the over sheet material of a card base material being a synthetic resin material through a magnetic tape. They are heat-pressed from a protection film-side and the magnetic tape and the protection film are made to closely adhere each other.
Abstract:
PROBLEM TO BE SOLVED: To provide a forgery-proof form, the forgery of which is difficult and the authenticity of which is easily proved, and which can be used as a bead, valuable securities, various types of ticket or a certificate of seal impression. SOLUTION: This forgery-proof form has a specified information entry part provided on the front face and a notice information part 4 provided on the back face. In addition, the document has a microcapsule ink 5 containing a heat sensitive agent which colors by cooling to show forgery confirmation information made up of a character, a mark or a pattern, printed on the notice information 4 entry part provided on the back face.
Abstract:
PROBLEM TO BE SOLVED: To suitably conceal copied and described secret information and to read by a simple method by using a compact implement of a low cost. SOLUTION: This copying cut form set 1 is of no-carbon pressure sensitive type, and comprises an upper position cut form 2 provided with a secret information fill-in column S1 at a predetermined part of a front surface and coloring agent microcapsule layer 4 executed at a corresponding area of the column S1 of a rear surface, and a lower position cut form 3 provided with a secret information copy column S2 corresponding to the column S at a predetermined part of a front surface and a developer and heat sensitive agent microcapsule layer 5 made of developer and decoloring type heat sensitive agent microcapsules executed at the column S2.
Abstract:
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 acceptance of orders of a small quantity and a large variety and a sheet using the ink. SOLUTION: The X ray-detectable inkjet ink contains an X ray-detectable fine metal particle colloid in a specific amount to the ink (solid) in the ink medium. The sheet has an X ray-detectable spot printed with the ink on a specific area of the sheet. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet-curing coating material capable of forming a coating film or a protection layer having excellent ink receptivity and fixability to a substrate such as a plastic film and a plastic card or an inkjet ink reception layer formed on the substrate as well as excellent fretting resistance and smoothness, and a sheet produced by using the ultraviolet-curing coating material. SOLUTION: The sheet 10 has a protection layer 6 formed on a prescribed part of at least one surface of a substrate or on a prescribed part of an inkjet ink reception layer 2 formed on the surface of the substrate 1 using an ultraviolet-curing coating material containing a photosetting component, a photopolymerization initiator and a thermoplastic resin.

Abstract:
PROBLEM TO BE SOLVED: To provide a novel pressure-sensitive adhesive composition which is coated on the surface of a base material to form an adhesive layer having appropriately peelable adhesiveness and makes it impossible to look through opacified information, and a sheet using the same. SOLUTION: The pressure-sensitive adhesive composition is coated on the surface of a sheet to be superposed, and dried to form an adhesive layer which does not adhere in a normal state, and when the above surface to be superposed is brought into contact with each other and a predetermined pressure is applied thereto, the surface to be superimposed can be allowed to peelably adhere to each other, and the pressure-sensitive adhesive composition comprises a natural rubber aqueous emulsion type adhesive as the base material and scaly, light-nontransmissible metallic fine particles, and excels in opacifying performance.
