  • Patent number: 8304059
    Abstract: A stretchable fabric for marking, having a laminated structure of a first adhesive layer 11 formed of a hot-melt adhesive composed of a thermoplastic polyurethane resin having physical properties including a melting point of 125 to 165° C., a melt viscosity of 8,000 to 15,000 Pa·s at 150° C., and a 100% modulus of 2 to 8 MPa, an interlayer 20 formed of a thermosetting polyurethane resin which is stretchable and opaque, a second adhesive layer 12 formed of the hot-melt adhesive composed of the thermoplastic polyurethane resin having the above-described physical properties, and a surface layer 30 formed of a thermosetting polyurethane resin which is stretchable and transparent, wherein a mark image has been formed on a front surface of the interlayer 20 or on a back surface of the surface layer 30.

  • Patent number: 6823623
    Abstract: For the purpose of obtaining disease-free seeds of high quality by efficiently controlling a seed borne disease of seeds of vegetable crops, ornamental plants and other herbage, seeds are subjected to a physical or chemical sterilization to reduce a fungal or bacterial amount held by the seeds and then the thus sterilized seeds are treated by an effective microorganism which is antagonistic against a pathogen of the seed borne disease. Controlling effect and fixing property of the effective microorganism can be enhanced by using a plurality of fungal or bacterial strains thereof. Examples of such effective microorganisms include fungi or bacteria belonging to the genus Pantoea or the genus Leclercia which is antagonistic against the pathogen belonging to the genus Xanthomonas.

  • Patent number: 5078909
    Abstract: A moisture-absorbent composition contains 100 parts by weight of thermoplastic resin and 5 to 400 parts by weight of at least one among the group consisting of magnesium sulfate (represented generally by MgSO.sub.4.NH.sub.2 O (O.ltoreq.n.ltoreq.3), aluminum oxide, calcium oxide, silicon oxide, zeolite, barium oxide, and cobalt chloride. A moisture-absorbent molded item is formed of this composition in a shape of a film, a sheet, a plate, a bag, a pellet, or a container. The molded item may be used as a cushion insert, etc. which requires moisture absorption properties. A moisture-absorbent composition and an molded item made of the composition are provided with an indicator function, by specifying the amount of anhydrous cobalt chloride.
