Abstract: The invention relates to a first compound which is a first amine or a first salt thereof, and to a second compound which is a second amine or a second salt thereof. The first compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of M[Rf1OSO2NSO2ORf2]n wherein Rf1 and Rf2 represent the same or different fluorine-containing monovalent organic groups. The first amine is prepared by reacting bis(chlorosulfonyl)amine with a fluoroalcohol represented by a general formula of Rf3OH wherein Rf3 represents the same of different groups which are identical with Rf1 and Rf2. The second compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of —[M[N—SO2ORf4OSO2]n]m— wherein Rf4 represents a fluorine-containing bivalent organic group.
