Abstract
The present application relates to a surface protective film, a method for preparing a surface protective film, and a method for manufacturing an organic light emitting electronic device.
Claims19
A surface protective film comprising:
- a base layer;
- and
- an adhesive layer provided on one surface of the base layer,
- wherein the adhesive layer includes a cured material of an adhesive composition including a urethane polymer;
- an acryl-based polymer;
- and a curing agent;
- the acryl-based polymer includes a (meth)acrylate monomer including an alkyl group having 10 or more carbon atoms;
- a (meth)acrylate monomer including a hydroxyl group;
- and a (meth)acrylate monomer including silicone as a monomer unit;
- and
- a peel strength when peeling a surface opposite to the base layer-provided surface of the adhesive layer from glass at a peeling rate of 1.8 m/min and a peeling angle of 180° is greater than or equal to 0.5 gf/in and less than or equal to 5 gf/in.
