  • Publication number: 20250206995
    Abstract: The present application provides a release composition, a release layer, a release film, and a pressure-sensitive adhesive film. The release composition of the present application has excellent curability, and thus can be stably cured to form a release layer. When the release layer has been formed, the present application can provide a release composition allowing to exhibit a stable residual adhesion rate even if the release layer is repeatedly applied to a pressure-sensitive adhesive layer or the like. The release layer of the present application can maintain desired release characteristics even if it is maintained at room temperature and a high temperature for a long time. In addition, the release layer can stably maintain a balance of high-speed and low-speed peeling forces.
