Abstract: The invention relates to a use of a coating layer on a paper substrate for blocking oxygen transfer through the coated paper substrate, wherein the coating layer on the paper substrate is obtainable by a process, which comprises the steps of (a) providing a paper substrate with a surface, (b) applying onto the surface of the provided paper substrate an aqueous coating mass, and (c) drying of the paper substrate with the applied aqueous coating mass to obtain the coated paper substrate, wherein the aqueous coating mass contains an aqueous dispersion of a copolymer P, which is obtainable by radically initiated emulsion polymerization of at least 40 parts by weight of styrene and 22 to 49 parts by weight of butadiene and optionally other monomers based on the sum total of the parts by weight of all monomers, which is always 100, in the presence of a first degraded starch. It relates further to a coated paper substrate obtainable with a coating mass comprising the aqueous dispersion of the copolymer P and a further saccharide, which is added after the polymerization of the monomers. It relates also to a process for manufacturing the coated paper substrate obtainable with a coating mass comprising the aqueous dispersion of the copolymer P and the further saccharide.
