Description
すなわち、本発明のセパレータ付き光学用表面保護フィルムは、基材フィルムの少なくとも片面に粘着剤層を有する光学用表面保護フィルム、及び、前記粘着剤層の前記基材フィルムと接触する面と反対面に、セパレータを有するセパレータ付き光学用表面保護フィルムであって、前記セパレータが、離型層とポリエステル系基材を有し、前記ポリエステル系基材が、空洞を有し、前記ポリエステル系基材の厚みが、２５〜１００μｍであり、前記セパレータの前記粘着剤層に対する１８０°きっかけ剥離力が、０．７Ｎ／５０ｍｍ以下であることを特徴とする。
That is, the optical surface protection film with a separator of the present invention is an optical surface protection film having an adhesive layer on at least one surface of the substrate film, and the surface of the adhesive layer opposite to the surface that comes into contact with the substrate film. In an optical surface protection film with a separator having a separator, wherein the separator has a release layer and a polyester-based substrate, the polyester-based substrate has a cavity, the polyester-based substrate of The thickness is 25 to 100 μm, and the 180 ° trigger peeling force of the separator with respect to the pressure-sensitive adhesive layer is 0.7 N / 50 mm or less.
＜セパレータ＞
本発明の表面保護フィルムは、基材フィルムの少なくとも片面に粘着剤層を有し、前記粘着剤層の前記基材フィルムと接触する面と反対面に、セパレータを有するものであって、前記セパレータが、離型層とポリエステル系基材を有し、前記ポリエステル系基材が、空洞を有し、前記ポリエステル系基材の厚みが、２５〜１００μｍであり、前記セパレータの前記粘着剤層に対する１８０°きっかけ剥離力が、０．７Ｎ／５０ｍｍ以下であることを特徴とする。前記セパレータは、粘着剤層の粘着面を保護する目的で、粘着剤層表面にセパレータを貼り合わせるものであり、特に特定の厚み、及び、空洞を有することで、セパレータ自体のコシ(剛性）を低く抑えことができ、粘着剤層表面からセパレータを剥離する際の剥離性や作業性に優れ、更に、空洞によるクッション性が付与でき、粘着剤塗工後に発生する恐れのある糊打痕等を防止でき、好ましい態様となる。
<Separator>
The surface protective film of the present invention has a pressure-sensitive adhesive layer on at least one surface of a substrate film, and has a separator on the surface of the pressure-sensitive adhesive layer opposite to the surface in contact with the substrate film , wherein the separator Has a release layer and a polyester-based substrate, the polyester-based substrate has cavities, the polyester-based substrate has a thickness of 25 to 100 μm, and the separator has a thickness of 180 to the pressure-sensitive adhesive layer. ° The trigger peeling force is 0.7 N / 50 mm or less. The separator is for bonding the separator to the surface of the pressure-sensitive adhesive layer for the purpose of protecting the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer. In particular, by having a specific thickness and a cavity, the stiffness (rigidity) of the separator itself is reduced. It can be kept low, it is excellent in peelability and workability when peeling the separator from the surface of the pressure-sensitive adhesive layer, and it can also provide cushioning due to cavities, eliminating glue dents and the like that may occur after pressure-sensitive adhesive application. This is a preferred embodiment.
