Provided is an adhesive composition for use in an optical film, which is used for adhering an optical film, shows excellent durability even in a high temperature and high humidity environment, and prevents the occurrence of white spots, and also provided is an optical film with an adhesive. The adhesive composition contains (A) an acrylic copolymer containing a reactive functional group, (B) an isocyanate compound, and (C) a compound having a hydroxy group and a rosin skeleton. L'invention propose un film optique avec agent adhésif et une composition d'agent adhésif pour film optique, utilisée pour coller un film optique, offrant une excellente durabilité même dans des conditions de chaleur et d'humidité élevées et permettant d'empêcher l'apparition de points d'imperfection blancs. La composition d'agent adhésif comprend un copolymère acrylique (A) comprenant un groupe fonctionnel réactif, un composé isocyanate (B) et un composé (C) à structure de colophane, qui possède un groupe hydroxyle.
