Description

黏著劑組合物及使用此物之偏光板Adhesive composition and polarizing plate using the same

本發明係關於一種黏著劑組合物及使用該黏著劑組合物的一偏光板。The present invention relates to an adhesive composition and a polarizing plate using the same.

一般而言，用以實現立體影像的顯示裝置例如液晶顯示裝置通常包含一圖案化的延遲膜。此種圖案化的延遲膜具有一技術配置，在該技術配置中，分別的圖案區域的光軸彼此形成於不同方向，以傳輸分別影像至戴著偏光眼鏡的觀眾的右眼及左眼，藉以具體化三維（即立體）影像。In general, a display device such as a liquid crystal display device for realizing a stereoscopic image generally includes a patterned retardation film. Such a patterned retardation film has a technical configuration in which the optical axes of the respective pattern regions are formed in different directions from each other to transmit respective images to the right and left eyes of the viewer wearing the polarized glasses, thereby Concrete three-dimensional (ie, stereo) images.

該圖案化的延遲膜通常藉由在一玻璃基板上形成一配向層，並在該配向膜塗液晶以實現配向性能來製備。光敏液晶材料被排列於該配向層上，並接著藉由如紫外光的光輻射交聯，以形成一聚合物液晶膜。此被形成的聚合物液晶膜可以根據伴隨著該配向層的表面配向的液晶的一配向方向，發揮如遲滯劑圖案的功能。The patterned retardation film is typically prepared by forming an alignment layer on a glass substrate and coating the alignment film with liquid crystals to achieve alignment properties. The photosensitive liquid crystal material is arranged on the alignment layer and then crosslinked by optical radiation such as ultraviolet light to form a polymer liquid crystal film. The formed polymer liquid crystal film can function as a retarder pattern in accordance with an alignment direction of the liquid crystal accompanying the surface alignment of the alignment layer.

該圖案化的延遲膜通常藉由一黏結劑或一黏著劑被黏著至一偏光板的一面，以及為了減少該顯示裝置的厚度及重量，近年來已被黏著至一聚乙烯醇偏光器。The patterned retardation film is usually adhered to one side of a polarizing plate by a bonding agent or an adhesive, and has been adhered to a polyvinyl alcohol polarizer in recent years in order to reduce the thickness and weight of the display device.

當在該圖案化的延遲膜及一偏光板或偏光器之間的黏著減少，在製造過程中處理或使用的期間，變形可能發生。再者，當長時間暴露於熱及潮溼的條件下，剝離的發生及斷層現象可能需被注意。此外，典型的聚乙烯偏光器可以在拉伸方向上收縮，因而涉及該延遲膜的位置上的不同延遲，進而導致3D立體效果中的劣化。When the adhesion between the patterned retardation film and a polarizing plate or polarizer is reduced, deformation may occur during processing or use during the manufacturing process. Furthermore, when exposed to heat and humidity for a long period of time, the occurrence of peeling and faulting may need to be noticed. In addition, typical polyethylene polarizers can shrink in the direction of stretching, thus involving different delays in the position of the retarding film, which in turn leads to degradation in the 3D stereoscopic effect.

因此，開發具有多種性能，如耐熱水性、耐濕熱性等以及良好黏著性的改良的黏著劑，仍是需要的。Therefore, it is still required to develop an improved adhesive having various properties such as hot water resistance, moist heat resistance, and the like, as well as good adhesion.

The composition has good heat resistance and moist heat resistance, as well as an improved 3D stereoscopic effect.

以下，本發明將被更詳細描述。Hereinafter, the present invention will be described in more detail.

黏著劑組合物Adhesive composition

本發明的該黏著劑組合物可包含一光聚合化合物。The adhesive composition of the present invention may comprise a photopolymerizable compound.

根據本發明的該光聚合化合物可包含下列化學式1及化學式2至少其中之一所示的一丙烯酸單體、以及具有一一級胺基的一苯乙烯單體至少其中之一。The photopolymerizable compound according to the present invention may comprise at least one of an acrylic monomer represented by at least one of Chemical Formula 1 and Chemical Formula 2, and a styrene monomer having a primary amine group.

本發明的該黏著劑組合物在其被使用在將一偏光器結合於一圖案化的延遲層時具有良好的黏著性，而此改善的黏著性可增強耐熱性及耐濕熱性。事實上，上述該丙烯酸單體及該苯乙烯單體兩者均可具有多個一級胺基，而此一級胺基連結於偏光器上的一極性基及包含在該圖案化的延遲層的一液晶塗覆層中的另一極性基，以形成一氫鍵。此外，上述該一級胺基與存在於包含在該液晶塗覆層中的一反應性液晶單體的一酯鍵進行醯胺化反應，以形成一共價鍵。因此，本發明的改善效果被認為係透過上述該等鍵而達成。The adhesive composition of the present invention has good adhesion when it is used to bond a polarizer to a patterned retardation layer, and the improved adhesion enhances heat resistance and moist heat resistance. In fact, both the acrylic monomer and the styrene monomer may have a plurality of primary amine groups, and the primary amine group is bonded to a polar group on the polarizer and one of the patterned retardation layers is included. Another polar group in the liquid crystal coating layer forms a hydrogen bond. Further, the primary amine group described above is subjected to a guanidation reaction with a monoester bond present in a reactive liquid crystal monomer contained in the liquid crystal coating layer to form a covalent bond.

The reason for this result is considered to be because the ring is bonded to a benzene ring of a reactive liquid crystal monomer present in the liquid crystal coating layer of the patterned retardation layer to perform a π-bond interaction.

本發明的該丙烯酸單體可為下列化學式1及化學式2至少其中之一所示。The acrylic monomer of the present invention may be at least one of the following Chemical Formula 1 and Chemical Formula 2.
