To provide a pressure-sensitive adhesive composition for an acrylic optical member not only satisfying transparency, light and weather resistances but also having a short curing time after coating (pressure-sensitive adhesion processing) without causing yellowing with time and to provide the optical pressure-sensitive adhesive sheet.
The pressure-sensitive adhesive composition comprises 100 pts. wt. of an acrylic polymer which is a copolymer of a monomer mixture containing (a) 100 pts. wt. of an alkyl (meth)acrylate, (b) 0.1-10 pts. wt. of a monomer having a hydroxy group in the molecule, (c) 0.05-3 pts. wt. of a monomer having any functional group of a carboxy group, an amide group and an amino group in the molecule and having ≥500,000 and ≤2,000,000 weight-average molecular weight according to gel permeation chromatography (GPC) and 0.01-5 pts. wt. of a polyol-modified xylylene diisocyanate cross-linking agent. The optical pressure-sensitive adhesive sheet is obtained by forming a pressure-sensitive adhesive layer composed of the pressure-sensitive adhesive composition for the optical member on one or both surfaces of a support.
