Beschreibung
Zusammenfassung:	The present invention relates to an annular laminate including a substrate and a rubber coating film layered in contact with the substrate, the rubber coating film including a crosslinked product of a composition including a crosslinkable perfluroelastomer (FFKM), a crosslinking agent including at least one compound represented by general formulas (1) through (3), and a solvent, and the thickness of the rubber coating film being 1-500 [mu]m. The present invention provides an annular laminate and a method for manufacturing the same, the annular laminate having good sealing properties even with low crushing pressure, and being usable as a seal material that exhibits high radical resistance at high temperature.
