Description
(透明基材)
透明基材20は、積層フィルムの基体となるフィルムであり、可視光線の透過性に優れた材料により形成される。透明基材20の形成材料としては、ポリエチレン、ポリプロピレン等のポリオレフィン、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート等のポリエステル、ナイロン6、ナイロン66等のポリアミド、ポリイミド、ポリアリレート、ポリカーボネート、ポリアクリレート、ポリエーテルサルフォン、ポリサルフォン等の透明樹脂や無機ガラスを利用できる。また、透明基材20は、複数の材料が積層された複合フィルムであってもよい。透明基材の厚みは、特に限定されないが、10〜200μmとすることが好ましい。
(Transparent substrate)
The transparent substrate 20 is a film that becomes a substrate of a laminated film, and is formed of a material that is excellent in visible light transmittance. Examples of the material for forming the transparent substrate 20 include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polybutylene terephthalate and polyethylene naphthalate, polyamides such as nylon 6 and nylon 66, polyimide, polyarylate, polycarbonate, polyacrylate, Transparent resins such as polyethersulfone and polysulfone, and inorganic glass can be used. The transparent substrate 20 may be a composite film in which a plurality of materials are laminated. Although the thickness of a transparent base material is not specifically limited, It is preferable to set it as 10-200 micrometers.
(貼合層)
貼合層22は、図1に示した接着層8を介して画像表示パネル2に貼り合わされる層であり、具体的には、アンチブロッキング層、高屈折率ハードコート層、高屈折率層、低屈折率層、ハードコート層の少なくとも1層からなる層である。
(Bonding layer)
The bonding layer 22 is a layer bonded to the image display panel 2 via the adhesive layer 8 shown in FIG. 1, specifically, an anti-blocking layer, a high refractive index hard coat layer, a high refractive index layer, It is a layer composed of at least one of a low refractive index layer and a hard coat layer.
貼合層22に添加する親水性添加剤としては、以下の[化1]に示すポリアクリレートや、以下の[化2]〜[化4]に示すエポシキアクリレートを使用できる。[化1]に示すポリアクリレートの具体例としては、BYK−380N、BYK−381(いずれもビックケミー株式会社製)、PC4300(DIC株式会社製)が挙げられる。また、[化2]〜[化4]に示すエポキシアクリレートの具体例としては、DA−212、DA−314、DA−911M(いずれもナガセケムテックス株式会社社製)が挙げられる。尚、複数種類の親水性添加剤を混合して使用しても良い。 The hydrophilic additive to be added to the bonding layer 22, polyacrylates and shown in the following [Chemical formula 1], the epo shiki acrylate shown in the following [Chemical Formula 2] - [Chemical Formula 4] can be used. Specific examples of the polyacrylate represented by [Chemical Formula 1] include BYK-380N, BYK-381 (all manufactured by Big Chemie), and PC4300 (manufactured by DIC). Specific examples of the epoxy acrylate represented by [Chemical Formula 2] to [Chemical Formula 4] include DA-212, DA-314, and DA-911M (all manufactured by Nagase ChemteX Corporation). A plurality of types of hydrophilic additives may be mixed and used.
上述した積層フィルム15及び16は、ロール状に巻回された透明基材20を引き出して搬送しながら、透明基材20の一方面に対して層形成を行い、層形成後の透明基材20を再度巻き取るロール・ツー・ロール法により形成することができる。その後、巻回した透明基材20を引き出して搬送しながら、透明基材20の他方面に対する層形成を行う。透明基材20への積層順序としては、透明基材20上に貼合層22を先に形成する場合と、透明基材20上に光学調整層21を先に形成する場合がある。図2の保護フィルム24のない積層フィルム15の層構成で貼合層22に親水性添加剤を添加した構成とする場合、貼合層22を形成した後に行う透明基材20の巻回時に、貼合層22に含まれる親水性添加剤が透明基材20の他方面または光学調整層21に転写されてしまう。透明基材20の他方面に転写された親水性添加剤は、光学調整層21の形成に影響を及ぼす可能性がある。一方、光学調整層21に転写された親水性添加剤は、透明導電層23の形成に影響を及ぼす可能性がある。 The laminated films 15 and 16 described above perform layer formation on one surface of the transparent substrate 20 while pulling out and transporting the transparent substrate 20 wound in a roll shape, and the transparent substrate 20 after layer formation. Can be formed by a roll-to-roll method. Thereafter, layer formation is performed on the other surface of the transparent substrate 20 while the rolled transparent substrate 20 is pulled out and conveyed. As a stacking order on the transparent base material 20, there are a case where the bonding layer 22 is formed first on the transparent base material 20 and a case where the optical adjustment layer 21 is formed first on the transparent base material 20. When it is set as the structure which added the hydrophilic additive to the bonding layer 22 by the layer structure of the laminated | multilayer film 15 without the protective film 24 of FIG. 2, at the time of winding of the transparent base material 20 performed after forming the bonding layer 22, The hydrophilic additive contained in the bonding layer 22 is transferred to the other surface of the transparent substrate 20 or the optical adjustment layer 21. The hydrophilic additive transferred to the other surface of the transparent substrate 20 may affect the formation of the optical adjustment layer 21. On the other hand, the hydrophilic additive transferred to the optical adjustment layer 21 may affect the formation of the transparent conductive layer 23.
(実施例3)
透明基材の一方面に、実施例2と同じ貼合層形成用塗工液2を乾燥後の膜厚が1.0μmとなるように塗布し、乾燥させた。その後、紫外線照射装置(フュージョンUVシステムジャパン、光源Hバルブ)を用いて照射線量300mJ/m2で紫外線照射をおこなうことにより塗膜を硬化させて、貼合層を形成した。
(Example 3)
The same bonding layer forming coating solution 2 as in Example 2 was applied to one surface of the transparent substrate so that the film thickness after drying was 1.0 μm, and dried. Thereafter, ultraviolet irradiation apparatus (Fusion UV Systems Japan, source H bulb) to cure the coating film by performing ultraviolet irradiation dose 300 mJ / m 2 was used to form a bonding layer.
