    摘要： An electrically conductive composite fiber comprising an electrically conductive layer formed of a polyester-based polymer (A) having a melting point of 200° C. or higher and containing from 23 to 33% by weight of electrically conductive carbon black, and a protective layer formed of a polyester-based polymer (B) having a melting point of 210° C. or higher, wherein the difference between the SP value of the (A) and the SP value of the (B) is adjusted to not greater than a predetermined value and the fiber strength and the elongation at break are adjusted within certain ranges. This can make it possible to obtain an electrically conductive composite fiber that has a superior antistatic performance, which is not degraded very much over a practical wearing for a long term, though it contains only a relatively small amount of electrically conductive carbon black, and that is suitable for the field of clothing such as clean room wears and working wears.

    摘要： The present invention relates to a composite material using titanium or a titanium alloy, and concerns such a composite material obtained through processes in which after an imidazole compound has been applied to the surface of titanium or a titanium alloy, an adhered is adhered thereto. The composite material of the present invention is obtained by adhering the adhere thereto by using an adhesive resin composition containing a thermoplastic resin having a fracture energy release rate G1C of 4500 J/m2 or more. The present invention makes it possible to provide a composite material using titanium or a titanium alloy, which exerts a superior adhesive strength stably at room temperature as well as even after exposure to a high-temperature, high humidity condition.
