PRESSURE SENSITIVE ADHESIVE COMPOSITION

摘要

PURPOSE: An adhesive composition provides a sealing layer for an adhesive film and an organic electronic device, which has excellent moisture blocking, transparency, and durability at high temperatures and high humidity. CONSTITUTION: An adhesive composition includes a binder resin, nanoclay modified by an organic modifier, and solvent. The nanoclay is a lamellar silicate. A manufacturing method of an adhesive film comprises a step of manufacturing an adhesive composition by mixing the dispersion of the nanoclay and the solvent into a solution including the binder resin; and a step of spreading the adhesive composition (22) onto a substrate film (21). The adhesive film has an optical transmittance of 90% or greater in a visible ray region and a haze of 3 % or less.
