The present invention provides a surface protective film which includes an adhesive layer on one surface of a substrate film, wherein the adhesive layer is a cured product of a composition containing: 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 peel strength adjusting agent; and a photoinitiator, the composition being solvent-free; and the adhesive layer has peel strength of 0.5 gf/in to 10 gf/in, as measured on glass at a peel angle of 180° and a peel rate of 1.8 m/min.

Surface protective film for optical member

Disclosed relates to a surface protective film including: a base layer; and an adhesive layer provided on one surface of the base layer, where the adhesive layer comprises a cured product of an adhesive composition, comprising: a urethane polymer; an acrylic polymer; and a curing agent, where the acrylic polymer comprises a monomer unit derived from an alkyl(meth)acrylate monomer having 10 or more carbon atoms, where a peel strength of the adhesive layer is 2 gf/in or more and 30 gf/in or less when a surface of the adhesive layer, opposite to a surface on which the base layer is provided, is peeled off from glass at a peel speed of 30 m/min and a peel angle of 180°, and where, in the adhesive composition, the acrylic polymer is comprised in an amount of 1 part by weight to 15 parts by weight based on 100 parts by weight of the urethane polymer.
