粘着剤付き反射防止フィルム

Antireflective film having tacky agent

Abstract

(57)【要約】 【課題】 リワーク性に優れ、従って、良好な作業性の もとに被貼着面に対して貼着することができ、しかも、 製品の廃棄時には被貼着面から完全に剥すことができる ことから、リサイクル性にも優れた粘着剤付き反射防止 フィルムを提供する。 【解決手段】 有機フィルム2の一方の面に反射防止層 3が形成され、他方の面に、被貼着面に対してリワーク が可能であると共に、被貼着面に貼着後完全に剥離可能 な粘着剤層4が形成された粘着剤付き反射防止フィルム 1。
PROBLEM TO BE SOLVED: To obtain a tacky film excellent in rework property and, accordingly, capable of attaching to a surface to be attached in good workability by forming an antireflective layer on either one surface of an organic film land forming a specific tacky agent layer on the other surface. SOLUTION: This antireflective film 1 having a tacky agent is obtained by forming an antireflective layer 3 on either one surface of an organic film 2 and forming a tacky agent layer 4 enabling rework to a surface to be attached and capable of completely releasing after attaching to the surface to be attached on the other surface. A transparent film of polyethylene terephthalate, polycarbonate, polymethylmethacrylate, or the like, is preferable as the organic film 2. For example, a laminated film comprising a transparent film having high refractive index and a transparent film having low refractive index can be formed as the antireflective layer 3. A rubber-based tacky agent consisting mainly of a polymer having ≤20°C glass transition temperature and rubber elasticity is preferable as the tacky agent of the tacky agent layer 4.
