| abstract |
The present invention provides a pressure-sensitive adhesive composition which causes little deterioration of a near-infrared absorbing dye due to ultraviolet rays and is suitable for forming an adhesive layer or the like for bonding a layered material for forming a plasma display or the like. A pressure-sensitive adhesive comprising a pressure-sensitive adhesive polymer (A), a near-infrared absorbing dye (B), an ultraviolet absorber (C) and / or a hindered amine light stabilizer (D). The composition, preferably a pressure-sensitive adhesive composition further comprising an antioxidant (E), and the pressure-sensitive adhesive polymer (A) have the following properties: (1) a glass transition temperature of -80 to -20 ° C; And / or (2) the pressure-sensitive adhesive composition having a weight average molecular weight of 250,000 or more.
