Abstract: The present disclosure provides a surface protective film which is used in a process of fabricating an encapsulation layer for an organic light-emitting diode, and makes it possible to prevent bubbles from being generated in the protective film or the surface smoothness of the protective film from being degraded, due to solvent volatilization from the protective film. Specifically, the present disclosure provides a surface protective film including an adhesive layer provided on one surface of a substrate layer, wherein the adhesive layer includes a cured product of an adhesive composition including: a urethane-based resin having a photoreactive group at the end or side chain thereof; a monofunctional (meth)acrylate monomer; a crosslinking agent having two or more photoreactive groups at the end thereof; a photoinitiator; and a photoreactive siloxane additive, the adhesive composition being solvent-free.

Abstract: A method for preparing a metal foam is provided which can freely control characteristics, such as pore size and porosity, of the metal foam, prepare the metal foam in the form of films or sheets which have conventionally been difficult to produce, particularly the form of thin films or sheets as well, and prepare a metal foam having excellent other physical properties such as mechanical strength. It is also possible to efficiently form a structure in which the metal foams as above are integrated with good adhesive force on a metal base material.
