An adhesive film for surface protection formed of a composition for adhesive films comprising a curable component including a urethane-based binder, a curing agent, and a plasticizer, the adhesive film having a peel strength variation rate of −50% to 20%, as calculated by the following Equation 1:
- Peel strength variation rate=[(P2−P1)/P1]×100,
- where P1 is an initial peel strength of the adhesive film with respect to an alkali-free glass plate (unit:
- gf/inch), and P2 is a peel strength of the adhesive film with respect to the alkali-free glass plate (unit:
- gf/inch) after the adhesive film is left at 85° C. and 85% RH for 10 days.
