Abstract
The present invention relates to an optical adhesive composition including: a thermosetting component including an isoprene-based rubber containing a carboxyl group, and a thermal curing agent; and a photo-curable component including an acrylic acid ester-based monomer, and a photoinitiator, in order to exhibit high barrier performance on the basis of a low water vapor transmission rate, and simultaneously, exhibit excellent adhesive performance by being applied to an optical device or a display device. In addition, the present invention provides an optical adhesive film including an adhesive layer including a photo-cured product of the optical adhesive composition, thereby obtaining advantages of ensuring an excellent cutting property and an excellent handling property, and improving a step difference absorbency.
