Abstract

The present invention relates to: a surface protection film comprising a base layer and an adhesive layer provided on the one surface of the base layer, the adhesive layer comprising a cured product of an adhesive composition containing a urethane polymer, an acrylic polymer, and a curing agent; and a method for manufacturing an organic light-emitting electronic device comprising same, wherein the adhesive layer leaves little residue after removal of the adhesive and causes little damage and contamination to the surface of an adhered material after being detached therefrom.

Description

technical field [0001] This application claims priority and benefit from Korean Patent Application No. 10-2019-0010028 filed with the Korean Intellectual Property Office on January 25, 2019, the entire contents of which are incorporated herein by reference. [0002] The present application relates to a surface protection film and a method of manufacturing an organic light emitting electronic device using the same. Background technique [0003] A plastic substrate used as a base material for a flexible display has a problem that its gas barrier properties for moisture, oxygen, and the like are remarkably low. Therefore, in the related art, this problem of the plastic substrate is alleviated by forming a barrier film applying various materials and structures on the substrate. [0004] However, recently, since existing barrier films are no longer used, there is a need to develop a surface protection film for a process capable of protecting a thin film encapsulation (TFE) layer...
