Claim:
A composition comprising at least one compound described by the formula X 1 (NR 1 R 2 ) n X 2 or an acid salt thereof, wherein X 1 represents H, an alkyl group having from 1 to 8 carbon atoms, or an aryl group having from 6 to 10 carbon atoms; and X 2 represents —NR 1 H; each R 1 independently represents H, an alkyl group having from 1 to 8 carbon atoms, an aminoalkyl group having from 2 to 8 carbon atoms, a hydroxyalkyl group having from 2 to 8 carbon atoms, or Z; each R 2 independently represents an alkylene group having from 2 to 8 carbon atoms; Z represents each R f independently represents a fluorinated alkylene group having from 1 to 6 carbon atoms; each Q independently represents —CF 2 —, —CF(CF 3 )—, —CF 2 CF 2 —, —CF 2 CF 2 CF 2 —, —CF 2 CF(CF 3 )—, —CF(CF 3 )CF 2 —, —CF 2 CF 2 CH 2 —, —CF 2 CH 2 —, or —CF(CF 3 )CH 2 —; and n and x independently represent integers greater than 2, wherein the compound has at least three Z groups, and wherein the number of primary and secondary amino groups in the compound is at least 3.
