CHEMICAL SOLUTION FOR INCREASING THE SURFACE CONDUCTIVITY AND/OR THE VOLUME CONDUCTIVITY OF A SUBSTRATE ABSTRACT OF THE DISCLOSURE 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 stabil- ity of the substrate. The solution consists of nitrocellu- lose and a quarternary 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 im- pregnated 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 com- pounds before casting to reduce film resistivity.
