Zusammenfassung: | To provide an easily adhesive film which exhibits high adhesion to a film such as a polarizer, hardly causes blocking, and is excellent in uniformity and durability.SOLUTION: An easily adhesive film (1) has an easily adhesive layer (15) on the surface of a transparent film base material (11). The easily adhesive layer (15) contains a binder resin and fine particles. The thickness of the easily adhesive layer is preferably 120-260 nm, and an average primary particle diameter of the fine particles is preferably 0.1-0.9 times the thickness of the easily adhesive layer. The easily adhesive layer can be formed by coating an easily adhesive composition containing a binder resin or its precursor substance, fine particles, an alkali component and a solvent onto the transparent film base material, and heating the easily adhesive composition.SELECTED DRAWING: Figure 1
【課題】偏光子等のフィルムに対する高い接着性を示し、ブロッキングが生じ難く、かつ均一性および耐久性に優れる易接着フィルムを提供する。【解決手段】易接着フィルム(1)は、透明フィルム基材(11)の表面に易接着層(15)を備える。易接着層(15)は、バインダ樹脂、および微粒子を含有する。易接着層の厚みは120~260nmが好ましく、微粒子の平均一次粒子径は、易接着層の厚みの0.1~0.9倍が好ましい。バインダ樹脂またはその前駆物質、微粒子、アルカリ成分および溶媒を含有する易接着組成物を透明フィルム基材上に塗布し、加熱することにより易接着層を形成できる。【選択図】図1 |
