<p>A pressure-sensitive adhesive composition for PDP front filters, characterized by comprising 100 parts by weight of a high-molecular acrylic polymer (A) having COOH or OH groups, a weight-average molecular weight (Mw) of 400,000-800,000, excluding 800,000, a molecular weight distribution (Mw/Mn) of 5 or lower, and a glass transition temperature (Tg-A) of -40 to -10°C and 5-20 parts by weight of a low-molecular acrylic polymer (B) having a weight-average molecular weight (Mw) of 10,000-50,000, a molecular weight distribution (Mw/Mn) of 5 or lower, and a glass transition temperature (Tg-B) of 40-120°C. It is further characterized by having been crosslinked so as to have a gel content of 50-90%, and by having a 90° peel strength of 5-15 N/25 mm. The pressure-sensitive adhesive composition for PDP front filters causes no adhesion failure including blistering even in thermal cycling.</p> |
