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.
