Abstract: The present invention provides a UV curable composition, a UV curable adhesive film and a UV curable adhesive tape. The UV curable composition comprises, based on the total weight thereof as 100 wt %: 25 to 60 wt % of an ethylene-vinyl acetate copolymer; 20 to 60 wt % of an epoxy resin; 5 to 20 wt % of glass bubbles; 0.3 to 8 wt % of a hydroxy-containing compound; and 0.5 to 5 wt % of a photoinitiator. According to the technical solution of the present invention, cohesive failure can be achieved in the cured adhesive film by the addition of glass bubbles into the UV curable system. The UV curable product provided in the present invention can achieve a good balance among the initial adhesivity, structural strength after curing, odorlessness or low odor, and other performance.
