ADHESIVE COMPOSITION HAVING A GEL CONTENT BASED ON CROSS-LINKING VIA KETO GROUPS OR ALDEHYDE GROUPS

摘要

The invention relates to an adhesive composition in the form of an aqueous polymer dispersion containing a tackifier, a compound, cross-linking via keto or aldehyde groups, and an adhesive polymer, which is formed by emulsion polymerization from soft (meth)acrylic ester monomers, acid monomers, monomers having keto or aldehyde groups, styrene and optionally additional monomers, wherein the polymerization can occur in the presence of molecular weight regulators. According to the invention, the adhesive polymer has specific gel contents. The adhesive composition may be used for producing adhesive labels, adhesive tapes or adhesive films.
