Abstract: Described is an aqueous one-component coating composition comprising dispersed polyurethane and phyllosilicate. The polyurethane carries acid groups which are at least partially neutralized with a hydrophilic base selected from inorganic bases and organic mono-amines. The hydrophilic base has a water solubility at 20° C. of at least 150 g/l, preferably of at least 200 g/l. The composition can be used for providing oxygen barrier properties to a polymer film.

Abstract: A description is given of the use of a one-component laminating adhesive for composite film lamination, and also of a method for composite film lamination. The laminating adhesive comprises an aqueous polymer dispersion preparable by radical emulsion polymerization of monomers comprising (a) at least 60 wt %, based on the total amount of monomers, of at least one monomer selected from the group consisting of C1 to C20 alkyl acrylates, C1 to C20 alkyl methacrylates, vinyl esters of carboxylic acids comprising up to 20 carbon atoms, vinylaromatics having up to 20 carbon atoms, vinyl halides, vinyl ethers of alcohols comprising 1 to 10 carbon atoms, aliphatic hydrocarbons having 2 to 8 carbon atoms and one or two double bonds, and mixtures of these monomers, and (b) at least 0.1 wt %, based on the total amount of monomers, of at least one monomer having at least one acid group, and (c) 0.

Abstract: Described is an aqueous coating composition comprising an aqueous dispersion of a radically polymerized addition polymer and phyllosilicate. The aqueous polymer dispersion has a particularly low electrical conductivity. The composition can be used for providing oxygen barrier properties to polymer films.

Abstract: Described are aqueous polymer dispersions and a method for producing them. The polymer dispersions comprise polymer particles having an average particle diameter of greater than 200 nm, monomodal particle size distribution, and uniform glass transition temperature, and are prepared by radical emulsion polymerization of a monomer mixture comprising ethylenically unsaturated, radically polymerizable monomers, using a polymer seed, less than 0.8 part by weight of emulsifier, and without protective colloids. The monomer mixture consists of a) at least 60 wt % of at least one monomer selected from the group consisting of C1 to C20 alkyl acrylates, C1 to C20 alkyl methacrylates, vinyl esters of carboxylic acids containing up to 20 carbons, vinylaromatics having up to 20 carbons, ethylenically ensaturated nitriles, vinyl halides, vinyl ethers of alcohols containing 1 to 10 carbons, aliphatic hydrocarbons having 2 to 8 carbons and one or two double bonds, and mixtures of these monomers, b) at least 0.

Abstract: Disclosed herein is a pressure-sensitively adhesive protective film formed from a polymer film coated with a crosslinked pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition contains a pressure-sensitive adhesive polymer which is formed by emulsion polymerization in the presence of saccharified starch from soft monomers which when polymerized as a homopolymer have a glass transition temperature of less than 0° C., from ethylenically unsaturated acids or acid anhydrides, and optionally further monomers different from (i) and (ii). The pressure-sensitive adhesive composition contains defined crosslinkers, with the crosslinking reaction brought about by the crosslinker being at an end before the pressure-sensitively adhesive protective film is adhered to a substrate.
