Claim:
1. A pressure-sensitive adhesive dispersion, comprising a water-dispersed polymer P1 formed by emulsion polymerization from a monomer mixture comprising: 75 to 90% by weight of n-butyl acrylate; more than 1% by weight and up to 3% by weight of ureidoethyl methacrylate; 0.5 to 2% by weight of (meth)acrylic acid; 1 to 3% by weight of hydroxypropyl acrylate; 0.1 to 2% by weight of glycidyl methacrylate; and 2 to 20% by weight of at least one additional monomer selected from the group consisting of methyl methacrylate and styrene, wherein: monomer amounts are based in each case on a sum of all monomers; a pressure-sensitive adhesive, formed by coating a PET carrier with the pressure-sensitive adhesive dispersion and drying, exhibits a shear strength value at 70° C. of more than 100 hours for 25×25 mm test strips of the coated PET carrier adhered to steel; and the pressure-sensitive adhesive exhibits an SAFT-test value of more than 180° C. for the 25×25 mm test strips of the coated PET carrier adhered to the steel.
