Abstract: The present invention provides a direct liquid-writing instrument without ink leakage from the pen-tip even after a long period of use. Specifically, it provides a direct liquid-writing instrument having an ink-retaining part in a bellows-like shape, in which at least the ink-retaining part in a bellows-like shape is made of: 20 to 95% by mass of (A) a polyamide-based resin; and 80 to 5% by mass of (B) at least one resin selected from a styrene-based resin, an olefin-based resin, and a polyphenylene ether resin.

Abstract: The present invention is a plated resin molded article and process of producing the plated resin molded article, wherein metal plating is carried out on the surface of a thermoplastic resin molded article and either of requirements (1), (2) and (3) described below is included: (1) the thermoplastic resin molded article contains a thermoplastic resin and a water-soluble substance, a step of carrying out the removal of fat from the resin molded article and a step of electroless plating are provided in combination, and a step of etching by an acid containing a heavy metal is not included; (2) the thermoplastic resin molded article contains a polyamide-based resin and a styrene-based resin, a step of carrying out the removal of fat from the resin molded article and a step of electroless plating are provided in combination, and a step of etching by an acid containing a heavy metal is not included; or (3) a step of contact-treating the thermoplastic resin molded article with an acid or base not containing a heav

Abstract: A resin composition comprises 1 to 60 parts by weight of a wollastonite fiber (in which the number-average fiber length is 1 to 30 ?m, the number-average fiber diameter is 0.1 to 10 ?m, and the proportion of the number of a fiber having a fiber length of 5 to 25 ?m relative to the total number of the fiber is 20 to 75%) and 0.1 to 20 parts by weight of an acid- or epoxy-modified olefinic resin having a melting point of 100 to 170° C., relative to 100 parts by weight of a thermoplastic resin (e.g., a polycarbonate-series resin). The weight-average molecular weight of the modified olefinic resin may be about 2.5×104 to 30×104. The resin composition may comprise a flame retardant. The combination use of the wollastonite fiber and the modified olefinic resin improves heat resistance, impact resistance and weld strength, even in the case of using a wollastonite fiber having a number-average fiber diameter of about 4 to 7 ?m and an average aspect ratio of about 1.5 to 3.

Abstract: The present invention provides a joining method using a method of laser welding wherein two resin molded bodies can be joined with high welding strength. Specifically, this is a method that joins two thermoplastic resin molded bodies using a method of laser welding; the first resin molded body is a laser light transmissive molded body comprising a thermoplastic resin and cellulose fibers with an ?-cellulose content of 80% or more; the second resin molded body is a laser light absorbent molded body containing a thermoplastic resin and a colorant; and the first resin molded body and the second resin molded body are welded by irradiating laser light from the first resin molded body side.

Abstract: An anti-fogging tray is obtained by coating a styrenic resin sheet with an anti-fogging agent to mold a tray. The anti-fogging agent comprises 1 to 50 parts by weight of a non-ether-series hydrophilic polymer excluding a polyvinyl alcohol (e.g., a polyvinylpyrrolidone), 5 to 150 parts by weight of an ether-series hydrophilic polymer (e.g., polyoxyethylene-polyoxypropylene block copolymer, and a nonionic surfactant having an oxyethylene unit), and 1 to 50 parts by weight of a silicone oil relative to 100 parts by weight of a polyhydric alcohol fatty acid ester (e.g., a sucrose fatty acid ester, a polyglycerin fatty acid ester). A coating layer comprising a surface-treating agent may be formed on one side of the resin sheet, and a mold-releasing layer containing a component selected from the ether-series hydrophilic polymer and the silicone oil may be formed on the other side of the resin sheet.
