Abstract:
The present invention provides a stretchable film including: a cured product of a composition which contains (A) a (meth)acrylate compound having silsesquioxane, (B) a (meth)acrylate compound other than the component (A) having a urethane bond, and (C) an organic solvent having a boiling point in the range of 115 to 200° C. at atmospheric pressure; wherein the component (A) is localized in the direction of a surface of the film. The stretchable film of the present invention is excellent in stretchability and strength as well as repellency on the film surface.
