US 12,767,866 B2 · UV curable adhesive composition and adhesive film, adhesive tape, and bonding component comprising thereof

Abstract

Disclosed are a UV curable adhesive composition, an adhesive tape comprising the UV curable adhesive composition, an adhesive film formed by UV curing of the adhesive composition, and a corresponding bonding member. The UV curable adhesive composition and the adhesive tape comprising the UV curable adhesive composition have a hybrid system of reactive polyacrylate/epoxy resin/core-shell rubber particles/hydroxy-containing compound, wherein a cationic photoinitiator is used to initiate curing of the epoxy resin.
