Abstract: The invention relates to an aqueous impregnating resin solution containing (A) between 77.5 and 99.8 wt. %, in relation to the impregnating resin solution, of aqueous condensates based on melamine and formaldehyde; (B) between 0.1 and 20 wt. %, in relation to the impregnating resin solution, of at least one specific quaternary ammonium compound; and (C) between 0.1 and 2.5 wt. %, in relation to the impregnating resin solution, of an aqueous hardener solution. The invention also relates to an aqueous impregnating resin solution consisting of constituents (A) and (B), and to an aqueous hardener mixture consisting of constituents (B) and (C). The invention further relates to an impregnating resin film containing fibrous substances containing cellulose and impregnated with the aqueous impregnating resin solution, and to the use of the aqueous impregnating resin solution, or impregnating resin film, for the antistatic finishing of coated materials.
