本発明の保護層は、保護性能の点からある程度の厚みがあることが好ましく、また着色層、透明電極等と相互作用せず、また、本発明の保護層は一時的な保護であることから後で比較的簡単に除去できるものであることが必要である。 The protective layer of the present invention preferably has a certain thickness from the viewpoint of protection performance, and does not interact with the colored layer, the transparent electrode, etc., and the protective layer of the present invention is temporary protection. It must be something that can be removed relatively easily later.
本発明の保護層は、以下に示すような粘着フィルム又はコーティング層が好適に用いられる。
本発明の粘着フィルムは、基材表面に粘着剤を有するフィルム又は基材と粘着剤との共押しフィルムが用いられる。本発明で用いる基材は、ポリエチレン、ポリエチレンテレフタレート等であり、粘着剤は、ゴム系又はアクリル系である。特に好ましくは、基材がポリエチレンであり、粘着剤がゴム系であることである。
