Abstract
A water- and oil-repellent, antistatic composition comprises (a) at least one nonpolymeric ionic salt consisting of (i) at least one cation selected from the group consisting of monovalent metal cations, divalent metal cations, and organic onium cations, and (ii) at least one weakly coordinating anion, the conjugate acid of the anion having an acidity greater than or equal to that of a hydrocarbon sulfonic acid, and with the proviso that the anion is organic or fluoroorganic when the cation is a metal; (b) at least one fluorochemical repellency-imparting additive or repellent; and (c) at least one insulating material. The composition exhibits good antistatic and repellency characteristics
