  • Publication number: 20230057536
    Abstract: An object is to provide an ink-jet ink satisfying rapid-drying properties, long decap time, and intermittent long-run printability. The object can be achieved by an ink-jet ink comprising an organic solvent, a surfactant, and a coloring material, wherein the organic solvent contains 1,3-dioxolane.

  • Publication number: 20060202386
    Abstract: The present invention relates to a dip molding having a low surface resistivity, the dip molding having a surface resistivity that is lower than that of a conventional product even after being washed with superpure water. The dip molding of the present invention has a surface resistivity, measured under an atmosphere of 20° C and a relative humidity of 65%, of 107 to 1010 ?/square. Since the dip molding of the present invention has a low surface resistivity, it can suitably be used as a glove for precision electronic component production and semiconductor component production.

  • Patent number: 6759473
    Abstract: By coating a dip-formed article with a coating agent comprising a polymer latex dispersion-stabilized with a water-soluble high-molecular-weight compound containing an alcoholic hydroxyl group, a coated article having excellent donning and putting off properties and anti-blocking property, and exhibiting greatly reduced fine particles-releasability is obtained.

  • Patent number: 6345394
    Abstract: A rubber glove comprising a main rubber layer and an inner covering layer, bonded to the main rubber layer, containing resin particles is disclosed. The resin particles are partially exposed on the skin-contacting surface of the inner covering layer to an extent such that, among resin particles visually observed in unit area of the skin-contacting surface, resin particles having a maximum particle diameter of 2-20 &mgr;m have a total projected area ratio A of 5-50%, as defined by the formula: A(%)=B/C×100, where B is total projected area of resin particles with a maximum particle diameter of 2-20 &mgr;m, and C is the unit area. The rubber glove can be easily donned and pulled off, and resin particles do not fall or do fall off only to a very slight extent upon donning or pulling off, and, when the inner covering layer is placed in contact with each other, the layer does not easily stick to each other.
