    摘要: The gasket of the present invention is mainly comprised of a pressure-sensitive adhesive sheet containing a non-halogenated flame retardant, and at least one surface thereof is a pressure-sensitive adhesive face of the pressure-sensitive adhesive sheet containing a non-halogenated flame retardant.
    According to the present invention, a highly flame retardant gasket having practically sufficient tight-sealing property, which does not produce a toxic halogen gas during combustion can be realized. In addition, a highly flame retardant gasket having practically sufficient tight-sealing property, which does not produce a toxic halogen gas during combustion, and does not cause corrosion and discoloration of a metal member to be an adherend can be realized.

    摘要: Provided is a water-dispersible acrylic pressure-sensitive adhesive composition capable of forming a removable pressure-sensitive adhesive layer which has satisfactory resistance to increase in adhesive strength and a good appearance and less causes staining on an adherend. The removable water-dispersible acrylic pressure-sensitive adhesive composition includes an acrylic emulsion polymer (A) formed from constitutive monomers essentially including 70 to 99.5 percent by weight of a (meth)acrylic alkyl ester and 0.5 to 10 percent by weight of a carboxyl-containing unsaturated monomer based on the total amount of the constitutive monomers; a water-insoluble crosslinking agent (B); an acetylenic diol compound (C); and a specific polyether defoaming agent (D). The acetylenic diol compound (C) has an HLB of less than 13, and the polyether defoaming agent (D) has a PO in a content of from 70 to 100 percent by weight and a number-average molecular weight of from 1200 to 4000.
