PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition excellent in light resistance and containing a tetraazaporphyrin-based dye, and a pressure-sensitive adhesive film and an optical filter.SOLUTION: The pressure-sensitive adhesive composition for the optical filter contains a tetraazaporphyrin-based dye, an ultraviolet absorber, a light stabilizer composed of a copper complex or a nickel complex, an acrylic pressure-sensitive adhesive, and an organic solvent in which solubility of the tetraazaporphyrin-based dye is (1 g)/(100 g) or more at 25°C, wherein solubility of the light stabilizer in the organic solvent is (3 g)/(100 g) or more at 25°C. The pressure-sensitive adhesive film and the optical filter possess a pressure-sensitive adhesive layer formed by using the composition. |
