SURFACE PROTECTIVE SHEET, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING ELECTRONIC DEVICE COMPONENT

摘要

Provided is a surface protective sheet whereby antifouling properties are enhanced and excellent wiping properties and sliding properties are ensured, the present invention is a surface protective sheet (1) having a protective film (3) on a surface of a substrate (2). The protective film (3) is configured from a cured product of a curable composition, the curable composition includes a coating material and a curable resin. The coating material is configured from a reaction product of at least compounds A, B, C and D. Compound A is an acrylic polymer having a hydroxyl group in a side chain thereof, compound B is a diisocyanate, compound C is a polyether polyol, and compound D is a photopolymerizable compound having both a hydroxyl group and a photopolymerizable group. The content of the coating material and the curable resin in the curable composition is preferably 2 parts by mass or more and 40 parts by mass or less of the coating material and 60 parts by mass or more and 98 parts by mass or less of the curable resin when the total amount of the coating material and the curable resin is 100 parts by mass.
