Abstract

The adhesive composition of the invention possesses a storage modulus of about 8*105 to about 1*108 dyne / cm2 and a gel fraction of about 83% to about 95% as defined by Equation 1: [Equation 1] gel fraction (%) = (A / B)*100, where, A is a mass measured after dissolving the adhesive at 23 DEG C for 48 hours in a solvent and then drying for 24 hours, and B is an initial mass. The invention also discloses an optical member which includes the adhesive composition of being the adhesive layer on one side or either side.

Description

technical field [0001] The present invention relates to an adhesive composition and an optical element using the same. More particularly, the present invention relates to an adhesive composition that prevents light leakage using a thermosetting interpenetrating polymer and has excellent durability and peel strength due to a blending effect of polymer compounds. Background technique [0002] Optical films include polarizing plates, color filters, phase difference films, elliptical polarizing films, reflective films, antireflective films, compensation films, brightness improvement films, orientation films, diffusion films, anti-scattering films, surface protection films, plastic LCD substrates, etc. They are used in a variety of optical elements including LCD display devices and the like. [0003] Here, the polarizing plate includes an iodine compound or a dichroic polarizing material oriented in a predetermined direction, and protective films such as triacetyl cellulose (TAC...
