Abstract: A description is given of a one-component pressure-sensitive adhesive composition in the form of an aqueous polymer dispersion comprising at least one pressure-sensitive adhesive polymer which is formed by emulsion polymerization of soft (meth)acrylic ester monomers, methacrylic acid, and optionally further monomers, where the polymerization takes place in the presence of chain transfer agents or styrene. The pressure-sensitive adhesive polymer has a gel content which is based at least partly on a reversible crosslinking via metal salts. The one-component pressure-sensitive adhesive composition can be used for producing adhesive labels, adhesive tapes or adhesive foils.

Abstract: Described is an aqueous dispersion comprising at least one polymer dispersed in water and having a weight-average molecular weight of less than 50 000 and a glass transition temperature of −40° C. to 0° C., preparable by emulsion polymerization in the presence of at least one chain transfer agent of a monomer mixture comprising at least 40% by weight of C1 to C20 alkyl (meth)acrylates, 0% to 30% by weight of vinylaromatics, at least 0.1% by weight of acid monomers, and 0% to 50% by weight of further monomers. The dispersion can be used in particular as a tackifier for adhesives.
