Abstract: The present invention provides a flame-retardant polyolefin resin composition having superior molding processability, a resistance to thermal deformation and suitable stretchability and intensity, which is rich in elastic deformation. The present invention provides a flame-retardant polyolefin resin composition comprising component A (a thermoplastic resin having a carbonyl oxygen atom in the molecular skeleton), component B (a polymer alloy containing an ethylene component and a propylene component), component C: a modified polyolefin polymer containing an acidic functional group and having a weight average molecular weight of 10,000-80,000 and component D (an inorganic metal compound), and substantially free of a halogen atom.

Abstract: An aqueous dispersion type pressure-sensitive adhesive composition contains an acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type and at least one hydrophilic polymer selected from the group consisting of polyalkylene glycols, polyvinylpyrrolidone, poly(vinyl alcohol)s, and poly((meth)acrylic acid), the amount of the hydrophilic polymer being from 0.5 to 15 parts by weight per 100 parts by weight, on a solid basis, of the acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type, and a pressure-sensitive adhesive product has a pressure-sensitive adhesive layer formed from the aqueous dispersion type pressure-sensitive adhesive composition.

Abstract: An aqueous pressure-sensitive adhesive composition of the invention comprises a rubber-based latex and a tackifier resin emulsion, wherein the tackifier resin emulsion is that obtained by emulsifying a tackifier resin in the presence of an emulsifier containing an ammonium salt of rosins; and the aqueous pressure-sensitive adhesive composition contains a water-soluble salt of casein as protective colloid. The aqueous pressure-sensitive adhesive composition is excellent in mechanical stability and insulating characteristics and has good moisture-proof adhesive strength.

Abstract: The present invention provides an aqueous-dispersion-type pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet formed thereof. This composition comprises a rubber latex, a tackifier resin emulsion, a dispersant composed primarily of a polycarboxylic acid (salt) having a hydrophobic side chain, and an emulsifier composed primarily of a polyoxyethylene alkyl ether sulfuric acid ester having an average polymerization degree of 16 to 80. A preferred dispersant contains carboxyl group at 2 to 6 mmol/g and an aqueous solution thereof at 1% by mass has a surface tension of 25 to 45 mN/m.

Abstract: According to the present invention, of the both surfaces of a cleaning sheet, a contact face to be rubbed against a cleaning object is a concave convex plane containing a convex part 1 and a concave part 2. By rubbing this concave convex plane against a cleaning object, a removal target (e.g., paste accumulated on the back of screen printing plate) attached to a cleaning object can be effectively removed.

Abstract: Novel glycosylated intracellular IL-1 receptor antagonist type II (icIL-1ra-II) is expressed and secreted in mammalian cells transformed with an expression vector where icIL-1ra-II is secreted by expressing icIL-1ra-II fused to the human growth hormone signal peptide. Also disclosed are a pharmaceutical composition containing glycosylated icIL-1ra-II as an active ingredient and a method for reducing IL-1 levels in patients having a condition involving overexpressed IL-1.
