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 a resin.

Abstract: The present invention provides a UV curable adhesive, wherein based on a total weight of the UV curable adhesive, the UV curable adhesive comprises: from 30 to 70 wt % of an acrylate oligomer; from 20 to 65 wt % of an acrylate monomer; from 1 to 10 wt % of acryloyl morpholine; from 1 to 15 wt % of a photo initiator; and from 0 to 10 wt % of a thickening agent, wherein the acrylate oligomer has a weight average molecular weight in a range of from 10,000 to 100,000 grams/mole and a glass transition temperature in a range of from −50 to 0° C. According to the technical solution of the present invention, the adhesive layer obtained from curing the UV curable adhesive is relatively thick (for example, 0.8 mm), and the adhesive layer has good adhesion property, cohesive force, and tackiness.
