Surface protective film

Abstract

The objective of this invention is to provide a surface protective film that easily removes wrinkles (bulges) generated when a surface protective film is adhered to a substrate during the removal step of a substrate serving as a support in the manufacturing process of flexible light-emitting devices, and preferably exhibits excellent easy peeling or excellent low-contamination properties. Furthermore, the objective of this invention is to provide an optical component or electronic component incorporating such a surface protective film. The surface protective film of the present invention comprises a substrate and an adhesive layer. The adhesive layer comprises a carbamate adhesive, which is formed from a carbamate adhesive composition. The carbamate adhesive composition comprises a base polymer (A), a polyfunctional isocyanate compound (B), and a light release agent (C). The base polymer (A) comprises a carbamate prepolymer. After being placed at a temperature of 23°C for 30 minutes, the high-speed shear force on the glass plate at a peeling speed of 3000 mm / min is less than 1500 gf / 100 mm2.
