ACRYLIC PRESSURE SENSITIVE ADHESIVE FOR THE POLARIZING FILM

摘要

The present invention relates to an acrylic PSA composition, and more particularly to an acrylic pressure-sensitive adhesive (PSA) composition that comprises the first PSA layer comprising a compound having a positive stress optical coefficient and an acrylic copolymer, and the second PSA layer comprising an acrylic copolymer. An acrylic PSA composition of the present invention can solve the light leakage problem of a liquid crystal display panel by reducing birefringence due to contraction of a polarizer attached to the liquid crystal display panel while maintaining key properties, such as durability and cuttability.
