Abstract

The present invention provides a stretchable film including: a cured product of a composition which contains (A) a (meth)acrylate compound having a siloxane bond, (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.

First claim

wherein the component (A) is localized in the direction of a surface of the film, and
wherein the amount of the component (C) is in the range of 20 to 300 parts by mass, based on 100 parts by mass of the solid contents in the composition.

2. The stretchable film according to claim 1 , wherein the ratio of the component (A) is in the range of 1 to 35% by mass based on the total mass of solid contents in the composition excluding the component (C).
