  • Patent number: 6586351
    Abstract: A stab-resisting material includes a carrier coated with solid particles, which is provided on a packet of fabrics, in which the coating on the carrier includes abrasive particles having a diameter of 0.1-3 mm, and in which the packet of fabrics is thicker than 1.5 mm. The abrasive particles may be provided on the carrier by an adhesive, which forms an elastic film after curing. In particular, a fabric made of Aramid or Nylon fibres may be used as the carrier material. The preferred adhesive is a bituminous adhesive or an adhesive with a base of polyurethane. This material is used in particular in protective clothing.

  • Patent number: 6569789
    Abstract: A conductive material suitable as a gasket material for shielding the electromagnetic wave and a method of fabrication thereof are disclosed. The conductive material is intended to protect electronics equipment and devices from an erroneous operation which otherwise might be triggered by the electromagnetic wave leaking from other electronic equipment or devices and also to prevent a radio wave interference with communication equipment. A composite material sheet composed of a synthetic fiber-structured sheet and a porous synthetic resin sheet integrally bonded to each other is plated with a metal. In order to improve the working efficiency for final applications, an adhesive layer covered with the releasing paper is formed on one of the sheet surfaces.

  • Patent number: 6323258
    Abstract: An aqueous ink composition having insoluble dye dispersed uniformly throughout by means of a coupling/dispersive (dual function) agent. The coupling/dispersive agent is characterized by association with insoluble dye molecules as well as by solubilization in a water based carrier medium. The resulting ink is water fast because the coupling/dispersive agent probably evaporates during drying or migrates away.

  • Patent number: 5126382
    Abstract: Metal ion crosslinked superabsorbent polymers and a process for making them are described wherein high concentrations of polyhydroxylated materials are incorporated in order to reduce the sensitivity of the superabsorbent composition to solutions containing dissolved salts. Also provided is a process for forming crosslinked superabsorbents containing high solids polymer content.
