Abstract
Coating compositions and their preparation are described. The compositions can be used to give surfaces a decreased electrical surface resistivity. Choline antistats are used in amounts of about 2% or less by weight, and are combined with long chain quaternary ammonium salt antistats, in a solution with a binder to give antistatic or stat dissipative coating compositions.
