Abstract
Official abstract text for this publication.
The present invention relates to an acrylic pressure-sensitive adhesive composition, and more precisely, an acrylic pressure-sensitive adhesive composition which is prepared by copolymerization of a vinyl and/or acrylic monomer having a cross-linkable functional group and comprises 100 weight part of a high molecular weight (meth)acrylic copolymer which is prepared by copolymerization of a vinyl and/or acrylic monomer harboring a cross-linkable functional group and whose weight average molecular weight is 40˜100 times as high as the entanglement molecular weight, 5˜50 weight part of a low molecular weight (meth)acrylic copolymer which does not contain a cross-linkable functional group and whose weight average molecular weight is 2˜15 times as high as entanglement molecular weight, and 0.01˜10 weight part of a multifunctional cross-linking agent. The acrylic pressure-sensitive adhesive composition of the present invention has reliable adhesion durability under high temperature and high humidity and at the same time reduces the light leakage due to the stress relaxation and enhances the cutting-efficiency of a polarizing plate.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acrylic pressure-sensitive adhesive composition for a polarizing plate, comprising: a) 100 weight part of a high molecular weight (meth)acrylic copolymer which is prepared by copolymerization of a vinyl and/or acrylic monomer having a cross-linkable functional group and whose weight average molecular weight is 56˜64 times as high as the entanglement molecular weight; b) 5˜50 weight part of a low molecular weight (meth)acrylic copolymer which does…
