Zusammenfassung:	Polyurethane-based pressure-sensitive adhesive (I), where the polyurethane comprises the chemical reaction product of at least the starting materials: (a) polyisocyanates comprising at least one aliphatic or alicyclic diisocyanate and at least one aliphatic or alicyclic polyisocyanate, and (b) at least one pressure-sensitively adhesive and hydroxyl functionalized polyurethane prepolymer, is claimed. Polyurethane-based pressure-sensitive adhesive (I), where the polyurethane comprises the chemical reaction product of at least the starting materials: (a) polyisocyanates comprising at least one aliphatic or alicyclic diisocyanate and at least one aliphatic or alicyclic polyisocyanate having an isocyanate functionality of three or more than three, where the amount-of-substance fraction of the aliphatic or alicyclic polyisocyanates having an isocyanate functionality is three or more than the proportion of the polyisocyanates being at least 18%, and (b) at least one pressure-sensitively adhesive, hydroxyl functionalized polyurethane prepolymer, is claimed. Independent claims are included for: (1) a pressure-sensitively adhesive, shaped structure, comprising at least one pressure-sensitive adhesive; (2) adhesive tape, comprising at least one pressure-sensitively adhesive layer, which comprises at least one pressure-sensitive adhesive; and (3) preparing the pressure-sensitive adhesive, where the starting materials are reacted, and the starting materials includes (a) and (b). Haftklebstoff auf Basis von Polyurethan, dadurch gekennzeichnet, dass das Polyurethan das chemische Umsetzungsprodukt aus zumindest folgenden Ausgangsstoffen umfasst: a) Polyisocyanate umfassend zumindest ein aliphatisches oder alicyclisches Diisocyanat und zumindest ein aliphatisches oder alicyclisches Polyisocyanat mit einer Isocyanat-Funktionalität von drei oder größer drei, wobei der Stoffmengenanteil der aliphatischen oder alicyclischen Polyisocyanate mit einer Isocyanat-Funktionalität von drei oder größer drei an den Polyisocyanaten mindestens 18 Prozent beträgt und b) zumindest ein haftklebriges, hydroxyl-funktionalisiertes Polyurethan-Prepolymer.
