Abstract:
PROBLEM TO BE SOLVED: To obtain a paper for preventing forgery, in which only copy or print having color tone entirely different from a manuscript (real paper) is obtained when duplication by a color copying machine or printing by color scanner and color printer is carried out and a forgery-preventing printed matter. SOLUTION: In this paper for preventing forgery, a coating layer (1) mainly composed of a pearl pigment having rainbow color and an adhesive is formed on the surface of a base paper (B), and a coating layer (2) mainly composed of pearl pigment with rainbow color different from hue of the pearl pigment with rainbow color used for the coating layer (1) and an adhesive is formed on the surface of the base paper in a place different from the coating layer (1) and hues of these two pearl pigments with rainbow color have complementary color relation to each other. This forgery-preventing printed matter is obtained by applying printing of prescribed items to the paper for preventing forgery.
Abstract:
PROBLEM TO BE SOLVED: To provide an anti-counterfeit material, capable of easily discriminating true or false without using a special tool or device and also having a high anti-counterfeit effect. SOLUTION: The chips of which base material is provided with a temperature responsive coated layer of changing its hue reversibly by the change of temperature, are produced. Addition of the chips to the anti-counterfeit paper allows discrimination the color-changing effect of the chips by the change of temperature to enable the discriminatement of true or false easily. By providing two kinds or more of the temperature responsive coated layers, higher effects can be obtained. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a sheet-like article for electric noise suppression, which is not too bulky because of its controlled thickness, is easy to handle and upon use owing to its sheet-like shape, and can prevent ignition due to heat generation of a circuit board when the article is used for EMC countermeasure for circuit boards, etc. SOLUTION: The sheet-like article for electric noise suppression has a configuration that conductive fibers and non-conductive fibers constitute a network-like structure. Preferably, the conductive fibers are fibrous carbon, particularly, CNT (carbon nanofiber). It is preferred that the conductive fibers are contained by 0.1-80%, a surface intrinsic resistance is 0.001-10 7 Ω/square, and a thickness is 10-200 μm. Preferably, the fibrous carbon covers ≥20% of the surface of the nonconductive fibers. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet-shaped object that can be manufactured at relatively low cost, prevents a film-forming solution from leaking from its back when it is used as a separating film support, is excellent in adhesiveness to a separating film, and can provide an inexpensive separating film of stable quality, and to provide a sheet-shaped object having a separating film. SOLUTION: The sheet-shaped object has a multilayered structure comprising an upper layer and a lower layer. The upper layer is a nonwoven fabric containing principal fibers made from synthetic fibers and has a basis weight of 20 to 100 g/m 2 , a thickness of 20 to 200 μm, and air permeability resistance of 0.1 to 5 seconds. The lower layer is a pulp sheet containing paper-forming pulp and has a basis weight of 20 to 100 g/m 2 , a thickness of 20 to 200 μm, and air permeability resistance of 0.1 to 8 seconds. The sheet-shaped object has a basis weight of 60 to 140 g/m 2 , a thickness of 50 to 150 μm, and air permeability resistance of 0.1 to 10 seconds. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an anti-counterfeit material facilitating discrimination between true or false without using any special tool or device and having a high anti-counterfeit effect. SOLUTION: This thread provided with a coated layer changing its hue by changing temperature on a base member is produced. Thereby, it becomes possible to distinguish the color-changing effect of the thread with the change of temperature by viewing, and easily discriminate the true or false. By incorporating the thread in paper, it is possible to prepare the paper used for anti-counterfeit. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a technique efficiently producing micro-character-containing thread excellent in metal gloss without requiring complicate steps such as metal deposition and etching (paster processing), a technique enabling efficient production even in small lot, an anti-falsification paper in which the thread is inserted into paper and an anti-falsification printed matter in which prescribed printing is applied to the anti-falsification paper. SOLUTION: In the anti-falsification paper in which thread is continuously inserted in the flow direction of paper, the thread is obtained by forming a micro-character (2) composed of a high-gloss metal ink layer on the surface of at least either one surface of a base film (1) and as necessary, further forming an adhesive layer (3) thereon. The anti-falsification printed matter is obtained by providing a prescribed printed layer on the anti-falsification paper. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a humidity conditioning coating excellent in moisture-absorbing and releasing properties and to provide a humidity conditioning material in which the coating is carried on a support and to provide a method for preventing dew condensation in which the humidity conditioning coating or material is used on the inside of a closed or semi-closed hollow structure. SOLUTION: The humidity conditioning coating is obtained by mixing an organic solvent singly or a mixture thereof, which are compatible with water, with a latex which is mixible with the above organic solvent, mixing the mixture with a material mainly consisting of a highly water-absorbing resin powder and uniformly dispersing the powder. The humidity conditioning material is obtained by applying the humidity conditioning coating onto the surface of a support. Dew condensation in the interior of the hollow structure is prevented by applying the humidity conditioning coating to the inner surface of closed or semi-closed hollow structure or installing the humidity conditioning material in the inner surface of the structure.

Abstract:
PROBLEM TO BE SOLVED: To provide a pollutant gas-removing paper adsorbing and removing various pollutant gases such as fumigation gas remaining after fumigation treatment, volatile organic compounds (VOC), or atmospheric pollutant gases, capable of readily processing into an arbitrary size, free from dropping of powder from the end, safely controlling the gas concentration in a storage chamber after fumigation, adsorbing and removing VOC or atmospheric pollutant gases generated from building materials of new houses or after reforming and capable of providing environment which is safe to human and objects thereby. SOLUTION: The pollutant gas-removing paper is a multiple layer combined paper having three or more layers obtained by providing combined paper carrying gas-adsorbing powder (mixture) having hydrophobic and/or hydrophilic property in an intermediate layer of the combined paper and forming tissue paper consisting essentially of papermaking fiber on the face side and the back side of the combined paper. Parts not carrying gas-absorbing powder are provided in both ends of the paper or in the both ends and in vertical direction or in horizontal and oblique directions and as necessary, perforated lines are provided in these parts. The paper can adequately be used under various conditions by specifying kinds of gas absorbing powder and formulation ratio of the powder. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an oilproof sheet-shaped article having low resistance to air permeation, and excellent oilproof properties, and preferably usable as a packaging material especially of a food using an edible oil. SOLUTION: The oilproof sheet-shaped article is obtained by forming at least one coated layer of 0.5-20 g/m 2 , containing starch and/or a polyvinyl alcohol and a fatty acid at least on one surface of a base material. The oilproof properties are improved by incorporating a crosslinking agent in the coated layer. At least two coated layers can be formed by further forming a coated layer consisting essentially of the fatty acid or a coated layer consisting essentially of the polyvinyl alcohol on the coated layer.
