[PROBLEMS] To prevent a decrease in adhesive force, an increase in haze, and a change in color even after being used for adhesion of an optical film for a long period of time under high temperature and high humidity. To provide a pressure-sensitive adhesive for optical films having excellent properties. An adhesive containing 0.1 to 3 parts by mass of a crosslinking agent is used for adhesion of an optical film with respect to 100 parts by mass of a urethane urea resin having a mass average molecular weight of 50,000 to 200,000.
