FIELD: chemistry.
SUBSTANCE: invention relates to a composition having impregnating effect, which can be used as an impregnating agent and/or an agent for top surfaces of different materials in different forms of application. An impregnating agent contains (A) at least one known impregnating active substance from a group consisting of (A1) fluorocarbon resins and (A2) fluorinated siloxanes and (B) at least one cationic polymer selected from chitosan, a chitosan derivative or other biopolymer, preferably from polyamides, particularly polypeptides, in most cases, essential amino acids (lysine, arginine, histidine, citrulline as well as in a combination), or from an amino-functionalised (meth)acrylate copolymer, particularly amino-functionalised styrene-acrylate copolymer or aliphatic and aromatic amino-functionalised polyurethane of a polyester and polycarbonate type.
EFFECT: agent has good oil- and dirt-repellent effect.
