Zusammenfassung:	The present invention relates to an UV-curable pressure sensitive acrylic adhesive obtainable by reacting in a first step a mixture comprising: (i) at least one acrylic monomer of formula (I)wherein R1 is H or CH3; and wherein R2 and R3 are both H or both CH3; and n is an integer from 0 to 22; or mixtures thereof; and (ii) at least one monomer which comprises a pendant reactive functional group selected from cycloaliphatic epoxides, oxetanes, mono-substituted oxiranes or mixtures thereof; and in a second step reacting the obtained mixture from the first step with (iii) at least one cationic photoinitiator; and (iv) optionally further additives. An article comprising this adhesive, and a method of manufacturing the article.
