Description

接著劑、偏光膜、液晶面板、光學膜及圖像顯示裝置 Reagent, polarizing film, liquid crystal panel, optical film and image display device

本發明係關於一種接著劑。該接著劑例如可用於偏光膜、各種光學膜及液晶單元之積層。又，本發明係關於一種包含該偏光膜、該各種光學膜、或該液晶單元之圖像顯示裝置。 The present invention is directed to an adhesive. The adhesive can be used, for example, for a laminate of a polarizing film, various optical films, and liquid crystal cells. Further, the present invention relates to an image display device comprising the polarizing film, the various optical films, or the liquid crystal cell.

於作為代表性之圖像顯示裝置之液晶顯示裝置中，起因於其圖像形成方式而於液晶單元之兩側配置有偏光元件。偏光元件通常係以至少於單面貼合有保護膜之偏光膜之形態使用。 In a liquid crystal display device which is a representative image display device, a polarizing element is disposed on both sides of a liquid crystal cell due to an image forming method. The polarizing element is usually used in the form of a polarizing film in which a protective film is bonded to at least one side.

作為用以將保護膜貼合於偏光元件之接著劑，提出有將聚乙烯醇系材料溶解於水而獲得之水系接著劑(例如，專利文獻1)或活性能量線硬化型接著劑(例如，專利文獻2)。根據活性能量線硬化型接著劑，與水系接著劑相比有如下優點：於偏光元件與保護膜之貼合時無需乾燥步驟；即便對於水分率較低之偏光元件亦獲得良好之接著性等。 As a binder for bonding a protective film to a polarizing element, a water-based adhesive obtained by dissolving a polyvinyl alcohol-based material in water (for example, Patent Document 1) or an active energy ray-curable adhesive (for example, Patent Document 2). According to the active energy ray-curable adhesive, compared with the water-based adhesive, there is an advantage that a drying step is not required when the polarizing element is bonded to the protective film, and good adhesion or the like is obtained even for a polarizing element having a low moisture content.

然而，關於先前之活性能量線硬化型接著劑(例如，專利文獻2)，亦有於加水環境下等嚴酷環境下接著變得不充分之情形，有要求進而高等級之耐水性之情形。 However, the conventional active energy ray-curable adhesive (for example, Patent Document 2) may be insufficiently formed in a severe environment such as a water-added environment, and there is a demand for a high-grade water resistance.

另一方面，提出有一種包含(甲基)丙烯酸酯聚合物、交聯劑及聚輪烷，且適於光學構件之黏著劑組合物(例如，專利文獻3)。然而，認為該黏著劑組合物未表現出與耐水性相關之課題，且就該組成或用途之方面而言亦不易產生耐水性課題。 On the other hand, an adhesive composition containing a (meth) acrylate polymer, a crosslinking agent, and a polyrotaxane and being suitable for an optical member has been proposed (for example, Patent Document 3). However, it is considered that the adhesive composition does not exhibit a problem related to water resistance, and it is difficult to cause a water resistance problem in terms of the composition or use.

End cap.

作為環狀分子，只要為將直鏈狀分子呈扡串狀地包藏於其開口部，可於直鏈狀分子上移動之分子，且為具有活性能量線聚合性基者則並無特別限定。再者，於本說明書中，「環狀分子」之「環狀」意指實質上為「環狀」。即，只要可於直鏈狀分子上移動，則環狀分子亦可不完全閉環。 The cyclic molecule is not particularly limited as long as it is a molecule which can be linearly entangled in the opening of the linear molecule and can be moved on the linear molecule, and has an active energy ray polymerizable base. In the present specification, the "ring" of the "cyclic molecule" means substantially "ring". That is, as long as it can move on a linear molecule, the cyclic molecule may not be completely closed.

作為環狀分子之具體例，可較佳地列舉：環狀聚醚、環狀聚酯、環狀聚醚胺、環狀聚胺等環狀聚合物，及α-環糊精、β-環糊精、γ-環糊精等環糊精。其中，就相對容易獲取且可大量選擇封端基之種類之方面而言，較佳為α-環糊精、β-環糊精、γ-環糊精等環糊精。環狀分子亦可於聚輪烷中或接著劑中混合存在2種以上。 Specific examples of the cyclic molecule include a cyclic polymer such as a cyclic polyether, a cyclic polyester, a cyclic polyether amine, and a cyclic polyamine, and an α-cyclodextrin and a β-ring. Cyclodextrin such as dextrin and γ-cyclodextrin. Among them, a cyclodextrin such as α-cyclodextrin, β-cyclodextrin, or γ-cyclodextrin is preferred in terms of being relatively easy to obtain and a large selection of the types of the terminal groups. The cyclic molecule may be mixed in two or more kinds in the polyrotaxane or in the adhesive.

於本發明所使用之聚輪烷中，上述環狀分子具有活性能量線聚合性基。藉此，即便於聚輪烷與活性能量線硬化性成分進行反應而硬化後，亦可獲得交聯點可動之接著劑，因此接著劑之耐水性提高。環狀分子所具有之活性能量線聚合性基只要為可與上述活性能量線硬化性化合物聚合之基即可，例如可列舉自由基聚合性基、及陽離子聚合性官能基。作為自由基聚合性基，例如可列舉(甲基)丙烯醯氧基、及(甲基)丙烯醯基，較佳為(甲基)丙烯醯氧基，更佳為丙烯醯氧基。藉由採用上述化學基作為自由基聚合性基，可達成較快之硬化速度，其結果，不僅可獲得較高之生產性，而且可賦予更高之耐水性。作為陽離子聚合性官能基，例如可列舉環氧基、及乙烯醚基。 In the polyrotaxane used in the present invention, the cyclic molecule has an active energy ray polymerizable group. Thereby, even if the polyrotaxane is reacted with the active energy ray-curable component and cured, a crosslinking agent capable of moving the crosslinking point can be obtained, so that the water resistance of the adhesive is improved. The active energy ray-polymerizable group of the cyclic molecule may be a group which can be polymerized with the active energy ray-curable compound, and examples thereof include a radical polymerizable group and a cationic polymerizable functional group. Examples of the radical polymerizable group include a (meth)acryloxy group and a (meth)acrylonitrile group, preferably a (meth)acryloxy group, more preferably an acryloxy group. By using the above chemical group as the radical polymerizable group, a faster curing rate can be achieved, and as a result, not only high productivity but also higher water resistance can be imparted. Examples of the cationically polymerizable functional group include an epoxy group and a vinyl ether group.

於使用環糊精作為環狀分子之情形時，活性能量線聚合性基較佳為經由任意適當之連接子(例如，下述式(I)或式(II)所表示之結構)而導入至環糊精之羥基。聚輪烷於1分子中所具有之活性能量線聚合性基之個數較佳為2個~1280個，更佳為100個~1100個，進而較佳為500個~1000個。藉由聚輪烷於1分子中所具有之活性能量線聚合性基之個數為特定個數以上，可確保硬化後之交聯點更多，因此賦予耐水性之效果提高。 In the case where cyclodextrin is used as the cyclic molecule, the active energy ray polymerizable group is preferably introduced to the appropriate one via a suitable linker (for example, a structure represented by the following formula (I) or formula (II)) The hydroxyl group of the cyclodextrin. The number of active energy ray polymerizable groups of the polyrotaxane in one molecule is preferably from 2 to 1,280, more preferably from 100 to 1,100, and still more preferably from 500 to 1,000. When the number of active energy ray-polymerizable groups in one molecule of the polyrotaxane is a specific number or more, the number of crosslinking points after curing can be ensured, and the effect of imparting water resistance is improved.

較佳為將疏水性修飾基導入至環狀分子。藉由疏水性修飾基之導入，可提高與活性能量線硬化性成分之相溶性。又，由於賦予了疏水性，故而於用作接著劑之情形時，可防止水滲入至接著劑層與被接著體之界面從而更進一步提高耐水性。作為疏水性修飾基，可列舉聚酯鏈、聚醯胺鏈、烷基鏈、氧伸烷基鏈、醚鏈等。作為具體例，可列舉WO2009/145073之[0027]~[0042]中記載之基。較佳之疏水性修飾基例如可具有以下之式(I)或式(II)所表示之結構。 It is preferred to introduce a hydrophobic modifying group into the cyclic molecule. The compatibility with the active energy ray-curable component can be improved by introduction of the hydrophobic modifying group. Further, since hydrophobicity is imparted, when it is used as an adhesive, water can be prevented from infiltrating into the interface between the adhesive layer and the adherend, thereby further improving water resistance. Examples of the hydrophobic modifying group include a polyester chain, a polyamine chain, an alkyl chain, an oxygen alkyl chain, and an ether chain. Specific examples include the groups described in [0027] to [0042] of WO2009/145073.

作為直鏈狀分子，只要為包藏於環狀分子，可利用機械結合而非共價鍵結等化學鍵結進行一體化之分子或物質，且為直鏈狀者，則並無特別限定。再者，於本說明書中，「直鏈狀分子」之「直鏈」意指實質上為「直鏈」。即，只要環狀分子可於直鏈狀分子上移動，則直鏈狀分子亦可具有支鏈。 The linear molecule is not particularly limited as long as it is a molecule or a substance which is incorporated in a cyclic molecule and can be integrated by chemical bonding such as mechanical bonding rather than chemical bonding, and is linear. Furthermore, in the present specification, "linear" of "linear molecule" means substantially "straight chain".

對實施例及比較例中所獲得之偏光膜進行耐水性評價。將評價結果與接著劑之調配一併示於表1。 The polarizing films obtained in the examples and the comparative examples were evaluated for water resistance. The evaluation results are shown in Table 1 together with the formulation of the adhesive.

<耐水性評價(1)> <Water resistance evaluation (1)>

將所獲得之偏光板裁斷成25mm×150mm之尺寸而製成樣品。將樣品於60℃之溫水中浸漬6小時之後，測定偏光板之自端部之剝離量(mm)。剝離量為10mm以下者為良好。 The obtained polarizing plate was cut into a size of 25 mm × 150 mm to prepare a sample. After the sample was immersed in warm water of 60 ° C for 6 hours, the peeling amount (mm) from the end portion of the polarizing plate was measured. The peeling amount is preferably 10 mm or less.

<耐水性評價(2)> <Water resistance evaluation (2)>

將所獲得之偏光膜裁斷成100mm×15mm之尺寸而製成樣品。將樣品於25℃之水中浸漬3小時，並自水中提拉樣品。其後，使用手及指甲抓撓樣品之端部，觀察保護膜是否自偏光元件剝離。利用以下之基準評價觀察之結果。 The obtained polarizing film was cut into a size of 100 mm × 15 mm to prepare a sample. The sample was immersed in water at 25 ° C for 3 hours and the sample was pulled from the water. Thereafter, the end of the sample was scratched with a hand and a nail to observe whether or not the protective film was peeled off from the polarizing element. The results of the observations were evaluated using the following criteria.

<基準> <benchmark>

◎：利用手及指甲無法剝離保護膜 ◎: The protective film cannot be peeled off by hand and nail

○：利用手及指甲可剝離保護膜之端部，但無法剝離中央部 ○: The end of the protective film can be peeled off by hand and nail, but the center part cannot be peeled off.

×：使用手及指甲可容易地剝離保護膜 ×: The protective film can be easily peeled off using hands and nails

如表1所示，使用包括含有活性能量線聚合性基之聚輪烷之接著劑所製造之實施例1~8之偏光膜之耐水性優異。另一方面，使用不含聚輪烷之接著劑所製造之比較例1及2之偏光膜之耐水性不充分。進而，使用包括不含有活性能量線聚合性基之聚輪烷之接著劑所製造之比較例3之偏光膜之耐水性不充分。藉由添加含有活性能量線聚合性基之聚輪烷而提高偏光膜之耐水性之原因並不確定，作出如下推測。 即，認為因聚輪烷之環狀分子之可動性從而交聯點可移動(所謂滑輪效應)，藉此對硬化後之接著劑賦予柔軟性，對偏光元件之表面凹凸之密接性增加，結果防止水滲入至偏光元件與接著劑層之界面。進而，認為藉由聚輪烷具有疏水性修飾基而對接著劑賦予疏水性之情況亦有助於防止水滲入至偏光元件與接著劑層之界面。 As shown in Table 1, the polarizing films of Examples 1 to 8 produced by using an adhesive containing a polyrotaxane containing an active energy ray-polymerizable group were excellent in water resistance. On the other hand, the polarizing films of Comparative Examples 1 and 2 produced by using an adhesive containing no polyrotaxane were insufficient in water resistance. Further, the polarizing film of Comparative Example 3 produced by using an adhesive containing a polyrotaxane containing no active energy ray-polymerizable group was insufficient in water resistance. The reason why the water resistance of the polarizing film is improved by adding the polyrotaxane containing the active energy ray-polymerizable group is not determined, and the following estimation is made. In other words, it is considered that the crosslinking point of the polyrotaxane is movable (the so-called pulley effect), thereby imparting flexibility to the adhesive after curing, and the adhesion of the surface unevenness of the polarizing element is increased. Water is prevented from penetrating into the interface between the polarizing element and the adhesive layer. Further, it is considered that the fact that the polyrotaxane has a hydrophobic modifying group to impart hydrophobicity to the adhesive also contributes to preventing water from penetrating into the interface between the polarizing element and the adhesive layer.
