Abstract: The present invention relates to a Polyurethane resin, obtainable by reacting an excess of one or more aliphatic diisocyanates with a group of isocyanate-reactive components consisting of one or more polyether polyols each having an average molecular weight in the range of 1000 to less than 3000 g/mol alone or in admixture with one or more polyester polyols each having an average molecular weight in the range of 1000 to less than 3000 g/mol; adding at least one diamine; adding of one or more polyols each having an average molecular weight of equal or less than 800 g/mol either before or after the reaction with the at least one diamine; and optionally reacting the product obtained in steps a) to c) with at least one terminating agent. The present invention is also related to binder materials and shrink sleeve printing inks comprising the above polyurethane resins.
