PROBLEM TO BE SOLVED: To provide a coating liquid which provides the excellent fixability of a liquid toner, does not restrict the sheet base material to be used to a costly coated paper, permits the use of ordinary paper, synthetic paper, plastic films, etc., and in addition, has excellent writing property and suitability to eraser and ink eradicator, and an electrostatic printing sheet using the same. SOLUTION: The coating liquid for forming a liquid toner receptive layer containing an ethylene-acrylic acid-based resin and a polyimide resin as essential components is used. By the electrostatic printing sheet formed by providing prescribed points of a base material surface with the liquid toner receptive layer formed by using this coating liquid, the purpose can be achieved.

Abstract:
PROBLEM TO BE SOLVED: To provide a release layer-forming ink which can easily form a release layer on a necessary specified place of a substrate by offset printing or the like without using a specific coating device due to its being low-cost, the possession of high releasing performance and, in addition, the printing ink suitability, furthermore does not require drying by a specific drying device after printing, and enables a secondary entry or an additional entry in the release layer due to its excellent writing properties, printability, marking properties and the like, and a sheet using the ink. SOLUTION: The release layer-forming ink comprises a vehicle having a glycol based solvent having a boiling point of ≥100°C as the major component and a powder of a releasing substance powder such as a tetrafluoroethylene resin powder. Preferably, the ink further comprises a binder resin. COPYRIGHT: (C)2003,JPO

Abstract:
PROBLEM TO BE SOLVED: To provide a chemiluminescent substance composition which is inexpensive, has good storage properties, may be easily coated on an object by a well- known method such as printing, and has high counterfeit-resistance as the chemiluminescent substance emits light and the luminescence is visible in the dark, and to provide a method for producing the same and a sheet using the same. SOLUTION: The method for producing the chemiluminescent substance composition containing highly water-absorbing polymer fine-particles carrying the chemiluminescent substance comprises a step (1) of preparing a solution and/or dispersion dissolved and/or dispersed the chemiluminescent substance, a step (2) of causing the solution and/or dispersion prepared in the step (1) to be absorbed in highly water-absorbing polymer fine-particles and a step (3) of dispersing the highly water-absorbing polymer fine-particles prepared in the step (2) in an oily dispersing medium.

SOLUTION: This non-contact IC label 1 consists of an IC chip piece 2 provided an IC chip 4 on one surface side and an antenna piece 3 provided with an antenna 5 on one surface side, an IC chip installation surface and an antenna installation surface of the respective pieces 2 and 3 are provided with adhesive structures 6 and 7 for integrating the respective pieces 2 and 3 in a separable way, and when the respective card parts 2 and 3 are integrated, the IC chip 4 and the antenna 5 are connected to carry out a function as a non-contact IC label.
Abstract:
PROBLEM TO BE SOLVED: To provide a desensitizing ink which is excellent in desensitizing action and in water resistance after printing, can form a desensitizing ink layer free from causing blur of a print image, and is highly suitable for ink jet printing. SOLUTION: The desensitizing ink is prepared by incorporating a photocurable acrylic component, a photopolymerization initiator, and fine porous particles into a vehicle containing a cationic resin and a glycol solvent having a boiling point of 100 deg.C or higher.
Abstract:
PROBLEM TO BE SOLVED: To provide a falsification-preventing ink excellent in printing ink adaptability capable of easily forming a falsification-preventing ink film having high falsification-preventing effects by partial printing or spot printing on necessary parts of a substrate by offset printing and the like, and applicable to securities, money-exchangeable papers, tickets, coupon tickets and the like, and to provide a sheet obtained using the same. SOLUTION: The falsification-preventing ink comprises a water-soluble photocurable component, a photopolymerization initiator, a water-soluble resin, porous particulates and water. An entry made on the falsification-preventing sheet brings about bleeding in several hours and the detection of the bleeding permits clear and easy verification of falsification.
Abstract:
PROBLEM TO BE SOLVED: To provide an ink for forming a sealing layer, which is excellent in a fitness of printing ink, by which a sealing layer sealable and sealable with a stamper without bleeding can be provided through printing in the portion of a base material having no sealability conventionally without impairing the characteristics intrinsic to the base material and, in addition, no peeling of the formed sealing layer develops by means of an OCR reader, a thermal head or the like. SOLUTION: The sealing layer is provided at the predetermined part of at least one side of the base material with an ink, which is prepared by mixing porous fine particles and a drier with a vehicle including an acrylic photosetting component and a photopolymerization initiator.
Abstract:
PROBLEM TO BE SOLVED: To obtain an ink for forming an impress layer having excellent printing ink suitability and capable of carrying out printing in a site requiring a conventional substrate having no impress ability without deteriorating characteristics essential to the substrate and providing an impress layer capable of carrying out impressing or stamping without blotting and without peeling the formed impress layer by an optical character reader (OCR), a thermal head, etc. SOLUTION: This ink for forming an impress layer is obtained by compounding hydrophobic porous fine particles and hydrophilic porous fine particles in a mass ration of the hydrophobic porous fine particles to the hydrophilic porous fine particles within the range of (5:95) to (95:5) in an amount of 10-70 pts. mass based on 100 pts. mass of a vehicle consisting essentially of a photo-setting component therewith. The impress layer is formed on at least one surface of the substrate by using the ink for forming the impress layer.
