Description

附有表面保護膜之光學構件Optical components with surface protective film

本發明係關於一種附有表面保護膜之光學構件。本發明之附有表面保護膜之光學構件係於光學構件之表面貼合有表面保護膜之構件。The present invention relates to an optical component with a surface protective film. The optical member with a surface protective film of the present invention is a member in which a surface protective film is attached to the surface of the optical member.

於液晶顯示裝置等光學製品之製造步驟中,通常在偏光板等光學構件之一表面經由黏著劑層貼合有剝離襯墊。並且,於將此種光學構件貼合於其他構件(例如其他光學構件)之情形時,在貼合前將剝離襯墊剝離使黏著劑層露出,再貼合於其他構件(例如專利文獻1)。 另一方面,為了防止加工、組裝、檢查、輸送等時表面之損傷,光學構件通常在露出面側貼合表面保護膜。此種表面保護膜於不再需要表面保護時自光學構件被剝離。 即,於液晶顯示裝置等光學製品之製造步驟中,通常,於光學構件之一表面經由黏著劑層貼合有剝離襯墊,且於另一表面貼合有表面保護膜。 於此種附有表面保護膜之光學構件中,於如上述般欲將剝離襯墊剝離時,重要的是僅於該剝離襯墊與黏著劑層之界面發生剝離。然而,於先前之附有表面保護膜之光學構件中,於如上述般欲將剝離襯墊剝離時,會發生光學構件與該剝離襯墊一起自表面保護膜剝離之問題,即,於光學構件與表面保護膜之界面發生剝離之問題。此種問題於光學構件較薄之情形時尤為顯著。 [先前技術文獻] [專利文獻] [專利文獻1]日本特許第3972676號公報In the manufacturing process of optical products such as liquid crystal display devices, a release liner is usually bonded to one surface of an optical member such as a polarizing plate via an adhesive layer. In addition, when bonding such an optical member to another member (for example, another optical member), the release liner is peeled off before bonding to expose the adhesive layer, and then bonded to another member (for example, Patent Document 1) . On the other hand, in order to prevent surface damage during processing, assembly, inspection, transportation, etc., the optical member is usually bonded with a surface protection film on the exposed side. Such a surface protection film is peeled off from the optical member when surface protection is no longer needed. That is, in the manufacturing steps of optical products such as liquid crystal display devices, usually, a release liner is attached to one surface of an optical member via an adhesive layer, and a surface protection film is attached to the other surface. In such an optical member with a surface protection film, when the release liner is to be peeled off as described above, it is important that peeling occurs only at the interface between the release liner and the adhesive layer. However, in the previous optical member with a surface protective film, when the release liner is to be peeled off as described above, the problem of peeling off the optical member from the surface protective film together with the release liner occurs, that is, in the optical member The problem of peeling off the interface with the surface protective film. This problem is particularly noticeable when the optical component is thin. [Prior Art Document] [Patent Document] [Patent Document 1] Japanese Patent No. 3972676

Fig. 1 is a schematic cross-sectional view of an optical member with a surface protective film according to an embodiment of the present invention. In FIG. 1, the optical component 1000 with a surface protection film of the present invention has a release liner 10, an adhesive layer (2) 20, an optical component 30, an adhesive layer (1) 40, and a substrate layer 50 in this order.

Regarding the optical member with a surface protection film of the present invention, the initial peeling force P of the optical member from the laminate of the optical member and the surface protection film is greater than the initial peeling force Q of the release liner from the laminate. By making the initial peeling force P greater than the initial peeling force Q, when the optical member with a surface protective film of the present invention is about to be peeled off the release liner, the optical member will not easily peel off from the surface protective film together with the release liner.

If the above-mentioned initial peeling force P/initial peeling force Q is within the above-mentioned range, when the optical member with a surface protective film of the present invention is to be peeled off the release liner, it will be more difficult for the optical member to separate from the release liner. The surface protection film peels off, that is, it is more difficult to peel off at the interface between the optical member and the surface protection film. When the thickness of the release liner is 50 μm and the peeling speed is 6 m/min, the initial peeling force P/initial peeling force Q is preferably 1.05 or more, more preferably 1.05-10, and even more preferably 1.1 ~5, 1.2~3 are particularly preferred. If the above-mentioned initial peeling force P/initial peeling force Q is within the above-mentioned range, when the optical member with a surface protective film of the present invention is to be peeled off the release liner, it will be more difficult for the optical member to separate from the release liner.
