  • Patent number: 9598612
    Abstract: An adhesive composition and an optical member using the same, the adhesive composition including an acrylic resin; an isocyanate cross-linking agent; and a carbodiimide cross-linking agent, wherein the adhesive composition exhibits a creeping distance of about 100 ?m or less when the composition attached to a glass substrate with a bonding area of about 1.5 cm×1.5 cm is left at about 22° C. and about 50% RH for about 3 days and is subjected to a load of about 10 gf/mm2 for about 1,000 seconds, and a storage modulus of about 1×105 to about 1×107 Pa at about 10 Hz and about 30° C. under conditions in which a sample has a thickness of about 1 mm and an elongation of about 10%.
