Abstract: A dip-forming composition is provided, which can give a dip-formed article that exhibits good softness of touch and comfortable fittingness, an excellent tensile strength and a high flexural fatigue resistance, and which is less likely to color even when worn and subjected to working for a long time period. The above problem is solved by the dip-forming composition which is obtained by converting an organic peroxide, which is solid at 30° C. under normal pressure, to an aqueous dispersion in the presence of a surfactant and a polymeric protective colloid, adding the dispersion to a conjugated diene rubber latex, and aging the mixture. The organic peroxide is preferably dibenzoyl peroxide or dilauroyl peroxide.

Abstract: A tailored blank article and a manufacturing method thereof, which is used for partitioning an inside and an outside such as a dashboard panel for partitioning an engine room of a car body and the inside of a car room. A thick plate blank and a thin plate blank are joined by a mash-seam welding or a laser welding, and are subjected to a pressing. Thereby, the thin plate blank is bent until an inner surface of the thin plate blank is made flush or almost flush with an inner surface of the thick plate blank, subsequently, a connection part having a portion connected over a welding portion is connected to at least one of an outer surface and the inner surface of the tailored blank article comprising the thick plate blank and the thin plate blank, and then an entire tailored article including the connection part is coated.
