  • Publication number: 20110008637
    Abstract: The invention provides a more effective optical brightener composition for coating paper substrates. The invention includes an optical brightening agent (OBA) and a glycerol based polymer. This combination results in a composition that provides a surprisingly large whitening effect and does not degrade the shade of the paper. As a result extremely high degrees of whiteness can be achieved without being frustrated by the greening effect.

  • Publication number: 20100209639
    Abstract: A gas barrier layered product and a method for producing the same are provided. The gas barrier layered product exhibits a high oxygen barrier property regardless of humidity, exhibits a high oxygen barrier property even after being subjected to retort processing, and is excellent in strength and transparency. In order to provide the gas barrier layered product, the gas barrier layered product includes a base material and a layer stacked on at least one surface of the base material. The layer is formed of a composition that includes: a hydrolyzed and condensed product of at least one compound (L) containing a metal atom to which at least one characteristic group selected from a halogen atom and an alkoxy group has been bonded; and a neutralized product of a polymer containing at least one functional group selected from a carboxyl group and a carboxylic anhydride group.

  • Patent number: 7754411
    Abstract: The present invention provides a slip sheet that protects a planographic printing plate in which the coefficient of static friction between corresponding surfaces of the slip sheet that contact an image-forming surface of the planographic printing plate is 0.35 or less, the surface strength of the slip sheet is 15 or more, or the Clark stiffness of the slip sheet is 20 to 50. In a production process of the planographic printing plate, the image-forming surface and the slip sheet are adhered by suitably charging, and following their lamination, the charge rapidly dissipates resulting in favorable separation, discharge characteristics and storage characteristics in an automatic plate feeder. In addition, sticking between the slip sheet and the image-forming surface during heat treatment can also be prevented simultaneously. This slip sheet is particularly effective for planographic printing plates of the heat mode type and photon mode type on which images are formed by exposure to laser light.

  • Publication number: 20100167082
    Abstract: The present invention relates to printing paper for security and a method of producing the same. According to the printing paper for security of the present invention, a white printing layer and a black printing layer are sequentially printed on a side of a first raw paper sheet and the white printing layer and a black printing layer are sequentially printed on a side of a second raw paper sheet. In addition, while a tag for detection that includes a magnetic material is provided between the black printing layer of the first raw paper sheet and the black printing layer of the second raw paper sheet, the first raw paper sheet and the second raw paper sheet are laminated. According to the present invention, since the tag for detection is not exposed to the outside of the printing paper, intentional damage to the tag for detection can be prevented.
