Abstract | A pressure-sensitive adhesive composition which is excellent in durability under high temperature and humidity conditions and can thus inhibit bright defect even when applied to a large-sized optical film; a pressure-sensitive adhesive; and an optical film. A pressure-sensitive adhesive composition including an acrylic copolymer (A) bearing a reactive functional group, an acrylic copolymer (B) and an isocyanate compound (C), wherein the quantity of the isocyanate compound (C) is 5 to 30 parts by weight per 100 parts by weight of a mixture of the acrylic copolymer (A) and the acrylic copolymer (B) and the elongation at break and 200% modulus as determined at 25 degrees C. by the tensile test are 300 to 1000% and 0.2 to 3 N/mm2 respectively. |
