Composition and method for treating substrates to reduce electrostatic charge and resultant article

A method for dissipating an electrostatic charge on a static-prone substrate comprising incorporating into said substrate an antistatic agent of the formula Q--L--(R--X).sub.d, wherein Q represents a normal or branched, saturated or unsaturated perfluoroaliphatic radical, L represents an ester or an ether linkage, R represents an alkylene-oxyalkylene or an alkylene-poly(oxyalkylene) group, and X represents at least one quaternary ammonium group of the formula ##STR8## and, optionally, a tertiary amine group of the formula ##STR9## wherein R.sub.1 and R.sub.4 independently represent --(C.sub.2 H.sub.4 O).sub.f --Z, Z being H, Q or ##STR10## wherein Q is as defined above, f being an integer from 1 to 50, R.sub.2 represents a C.sub.1 -C.sub.4 alkyl group, R.sub.3 and R.sub.5 independently represent a normal or branched, saturated or unsaturated C.sub.6 -C.sub.22 aliphatic group, A represents an organic or inorganic anion and d is 1 or 2 in an amount effective to impart to said substrate a surface resistance value in the range of from about 10.sup.6 to about 10.sup.12 ohms, a 90% electrostatic charge decay time of 10 seconds or less, or both.
