ABSTRACT:
A chemical solution to be applied to a substrate either as a surface coating or as an impregnating solution which, in both cases, increases the conductivity and in the case of impregnation also increases the dimensional stability of the substrate. The solution consists of nitrocellulose and a quaternary ammonium compound both dissolved in ethylene glycol monomethyl ether or, alternatively, methyl alcohol. The porous substrates such as paper, vellum and permeable materials like cellophane may be impregnated with the solution. Both the porous and permeable substrates and non-porous substrates, such as polyester films, may utilize the benefits of this solution as a face, back or intermediate conductive surface coating. The chemical solution can also be kneaded in film compounds before casting to reduce film resistivity.
