1,158,384. Antistatic coating. HENKEL & CIE G.m.b.H. 24 Feb., 1967 [25 Feb., 1966], No. 8918/67. Heading B2E. [Also in Divisions C3 and D1] An antistatic finish on woven or knitted fabrics and foils of non-conducting plastics is produced by treating the above with a filmforming coating composition containing electron donors and electron acceptors, the electron donors being polymers of mono- or polynurclear aromatic compounds or heterocyclic compounds, containing ring systems which carry electron repelling groups and the ionisation potential (I) of which is less than 8.0eV, and the electron acceptors being monomeric, olefinically unsaturated, benzonoid or auinonoidal compounds with electron-attracting groups, the electron affinity (EA) of which is more than 1.0 eV, in a molar ratio of acceptor to donor of 1:500 to 2:5, while I-EA is 4.5 to 6.0 eV.
