<p>A pressure-sensitive adhesive composition which, when a sample having a copper mesh bonded thereto is subjected to a moisture resistance test, is prevented from discoloring or fading. Also provided is an optical filter having excellent moisture resistance and prevented from discoloring or fading. The pressure-sensitive adhesive composition (first pressure-sensitive adhesive (14)), which is used for bonding a copper mesh (12) to an adherend (antireflection film (11)), comprises an acrylic pressure-sensitive adhesive having an acid value of 7 mg-KOH/g or lower and a dye having neither a hydroxy group nor an amino group. In the pressure-sensitive adhesive composition, the dye preferably is at least one member selected from the group consisting of anthraquinone dyes and porphyrin dyes. The optical filter (10) comprises an adherend (antireflection film (11)) and a copper mesh (12) bonded thereto through the pressure-sensitive adhesive composition (first pressure-sensitive adhesive (14)).</p> |
