Abstract: A reactive hot melt adhesive has a glass transition temperature of from 45° C. to 100° C. The reactive hot melt adhesive includes the reaction product of: an isocyanate component and an isocyanate reactive component chosen from a polyester, a polyether, and combinations thereof. The isocyanate component and the isocyanate reactive component react in the presence of a styrene acrylic resin that is free of hydroxyl functionality and that is the reaction product of 60 to 80 wt % of one or more monomers chosen from C1 to C20 alkyl acrylates and methacrylates and 20 to 40 wt % of one or more monomers chosen from vinylaromatics having a vinyl moiety having 2 or 3 carbon atoms.

Abstract: Described is an aqueous cold seal adhesive in the form of an aqueous polymer dispersion comprising a mixture of a first polymer and a second polymer, wherein the first polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of C1 to C20 alkyl (meth)acrylates and has a glass transition temperature of less than 0° C.; and wherein the second polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of vinylaromatics having up to 20 C atom, and has a glass transition temperature of at least 50° C. Also described are cold sealable coated polymer films coated with the aqueous cold seal adhesive and a method for producing a cold-sealed pack by applying the aqueous cold seal adhesive to a packaging substrate.
