CATIONIC PRESSURE SENSITIVE ADHESIVE UV CURED BY MEDIUM MERCURY BULBS

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) whereinR1 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 are also related. 本发明涉及可紫外固化的压敏丙烯酸系粘合剂，其可通过以下方式获得：在第步中，使包含以下物质的混合物反应：(i)至少种式(I)的丙烯酸系单体或它们的混合物，其中R是H或CH；并且其中R和R均为H或者均为CH；并且n是0至22的整数；和(ii)至少种包含侧链反应性官能团的单体，所述包含侧链反应性官能团的单体选自脂环族环氧化物类、氧杂环丁烷类、单取代的环氧乙烷类或它们的混合物；以及在第二步中，使从第步获得的混合物与(iii)至少种阳离子光引发剂和(iv)任选存在的其它添加剂反应。本发明还涉及包含所述粘合剂的制品以及制备所述制品的方法。
