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中に空洞を有し、前記ポリエステル系基材の比重が１．２ｇ／ｃｍ３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 the optical surface protection film with a separator having a separator, wherein the separator has a release layer and a polyester-based substrate, having a cavity in the polyester-based substrate, the polyester-based substrate The specific gravity is 1.2 g / cm 3 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中に空洞を有し、前記ポリエステル系基材の比重が１．２ｇ／ｃｍ３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、特にポリエステル系基材が空洞を有することで、セパレータ自体の重量を低く抑えることができ、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 is an optical surface protective film having an adhesive layer on at least one surface of a substrate film, and a separator having a separator on the surface of the adhesive layer opposite to the surface in contact with the substrate film. An optical surface protection film, wherein the separator has a release layer and a polyester-based substrate, has a cavity in the polyester-based substrate, and has a specific gravity of 1.2 g / cm 3 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. It is excellent in workability, and can provide a cushioning property due to cavities, and can prevent glue dents and the like that may occur after application of the adhesive, which is a preferable embodiment.
