Description

201139461 六、發明說明: 【發明所屬之技術領域】 本發明是有關於一種醯化纖維素膜、使用該醯化纖維 素膜的偏光板及液晶顯示裝置。詳細而言,本發明是有關 於一種用作可改善與偏光片組合時的高溫高濕下的偏光板 财久性的偏光板保護膜的醯化纖維素膜、使用該醯化纖維 素膜的偏光板及液晶顯示裝置。 【先前技術】 液晶顯示裝置作為消耗電力小且省空間的圖像顯示裝 置’其用途逐年擴大。先前,液晶顯示裝置的較大的缺點 疋顯示圖像的視角依存性大,但垂直配向(Vertical Alignment’ VA)模式等廣視角液晶模式已得到實用化, 藉此於電視等要求高品質的圖像的市場或要求設置於室外 的市場’液晶顯示裝置的需求亦正迅速擴大。 液晶顯示裝置的基本構成是於液晶單元的兩側設置有 偏光板。上述偏光板承擔僅使固定方向的偏波面的光穿過 的作用’液晶顯示裝置的性能受到偏光板的性能的較大的 影響。偏光板一般是包含偏光片與透明保護膜的構成,上 述偏光片包含使碘或染料吸附配向而成的聚乙烯醇膜等, 上述透明保護膜是貼合於該偏光片的表背兩侧。以乙酸纖 維素為代表的醯化纖維素膜因透明性高,可容易地確保與 偏光片中所使用的聚乙稀醇的密接性,故廣泛地用作偏光 板保護膜。近年來,實際情況是於將液晶顯示裝置設置在 高溫高濕下的室外時,亦要求高品質的圖像,而要求偏光 4 201139461 板保護膜改善與偏光片組合時的高溫高濕下的偏光板耐久 性。 首先,就上述觀點而言,一般用作偏光板的保護膜的 酿化纖維素膜需要高透明性(低濁度)、良好的透濕性(不 過高且不過低)、良好的光學性能,先前是藉由添加特定的 塑化劑來調整成滿足性能。但是,作為具有代表性的塑化 劑的磷酸二苯目旨(Triphenyl Phosphate,ΤΡΡ)等鱗酸酯類 於對醢化纖維素膜進行製膜時在乾燥步驟中昇華,且附著 於製造線上的污染物落下至膜上而引起面狀故障等問題。 另外’除該問題以外,就提供環保的偏光板保護膜及其製 造方法的觀點而言’亦要求不使用顧酯作為醯化纖維辛 膜的塑化劑。 另一方面,作為可添加於醯化纖維素以外的其他改性 =素中的塑化劑,已知有各種化合物,自先前以來已知 可將醣類及其衍生物作為塑化劑而添加。例如於專利文 =中記财藉由向含該粉與解基纖維素的塑膠 物中添加作為塑化劑的半乳糖,而可提 . 械物性均優異且環保的顧_軸錢。轉度與機 =在用於光學膜用纖維素臈的塑化劑的用途中,醣 類及”何生物亦適合,於贿及其射物之中,已知 糖醋化合物關子。例如,於專散獻2中,相對於乙2 化度為59.5% (總醯基取代度約為 用源自六伽(冰_輸少5__^=被= 代而成的糖醇的醋化塑化劑。於專利文獻3中,相二= 201139461 乙醯基取代度為2.5的乙酸纖維素,使用醣類的羥基的8〇0/〇 〜99%被酯化而成的塑化劑(參照該文獻[〇〇32]、[〇115]、 [0134])。於專利文獻4中,記载有相對於總醯基取代度為 2.1〜2.7的醯化纖維素,使用將醣類的羥基全部或部分酯 化而成的塑化劑’但可理解成使用實際所使用的糖酯化合 物的羥基被100%酯化而成的塑化劑(參照該文獻例示化 合物1〜例示化合物1〇等)。於專利文獻5中,相對於總 醯基取代度為2.7〜2.95的醯化纖維素,將取代度不同的 幾種糖酯化合物混合來用作塑化劑,上述糖酯化合物是單 醣類〜二醣類的經基被部分醋化而成的糖醋化合物(參照 該文獻[0393],例示化合物3〜例示化合物6、例示化合物 9、例示化合物18,[表3]〜[表6]等)。 但是,於該些文獻中,實質上僅揭示了酯取代度比較 高的糖酯化合物的使用例,尤其於混合使用取代度不同的 幾種糖酯化合物的專利文獻5中,僅揭示了低取代度的糖 酯化合物的添加比例非常少的形態。進而,於任一文獻中, 均未記載對醯化纖維素的總醯基取代度(特別是乙醯基取 代度)的範圍與糖酯化合物的酯取代度的關係性進行過研 究的例子。即,並未揭示醢化纖維素(特別是乙酸纖維素) 的乙酿基取代度與糖酯化合物的酯取代度的最佳的組合。 另外,於該些文獻中’亦未對將所獲得的偏光板保護 膜與偏光片組合時的高溫高濕下的偏光板耐久性進行研 究。 [專利文獻1]日本專利特開平5-320418號公報 6 201139461 [專利文獻2]日本專利特開2001-247717號公報 [專利文獻3]日本專利特表2005-515285號公報 [專利文獻4]WO2007/125764號公報 [專利文獻5JW02009/031464號公報 【發明内容】 於此種狀況下’本發明者等人自代替或改良磷酸三苯 酯(TPP)等先前所使用的塑化劑的觀點出發,針對上述 專利文獻2〜專利文獻5中所記載的化合物,研究了該些 化合物與乙醯基取代度為2.7以上、未滿2.95的醯化纖維 素膜組合時所獲得的膜的物性。但是,可知當使用專利文 獻2〜專利文獻5中所$己載的南取代度的糖醋化合物時, 無法獲得透明性、透濕性及光學性能等所期望的膜物性, 與偏光片組合時的兩溫南濕下的偏光板财久性亦不充分, 而要求進一步的改善。 本發明的目的在於提供一種透明性、透濕性及光學性 能良好,可改善與偏光片組合時的高溫高濕下的偏光板耐 久性的乙酸纖維素膜。另外,本發明的目的在於提供一種 使用該醯化纖維素膜的偏光板、以及使用其的液晶顯示裝 置。 本發明者等人為了解決上述課題而努力研究的結果, 發現當使將作為塑化劑的特定的酯取代度的範圍的糖酯化 合物製成取代度不同的混合物而成者、與特定的乙醯基取 代度的範圍的醯化纖維素組合來使用時,可獲得透明性、 透濕性及光學性能良好,可改善與偏光片組合時的高溫高 7 201139461 濕下的偏光板耐久性的酿化纖維素膜。 即’上述課題是藉由以下的構成的本發明來解決。 [1] 一種醯化纖維素膜,其特徵在於:包含酯取代度

2.95的醯化纖維素。若乙醯基取代度為2 7以上,則與滿 足後述的條件的糖酯化合物(例如,特定的取代度的蔗糖 苯曱酸酯等)的相容性良好,膜不易白化,故較佳。進而, 除透明性以外,透濕度或含水率亦變得良好,故較佳。另 外,偏光板耐久性或膜本身的濕熱耐久性亦變得良好,故 較佳。另一方面,若取代度未滿2.95,則光學性能明顯變 得良好,故較佳。 上述醯化纖維素的乙醯基取代度更佳為2 75〜2 9〇, 特佳為2.82〜2.87。 ’ 再者,總醯基取代度的較佳的範圍亦與上述乙醯美 代度的較佳的範圍相同。 a 再者,醯基的取代度可依據ASTM_D817 96中所a 的方法進行測定。未被醯基取代的部分通常作為羥武而$ 作為取代於纖維素的羥基上的碳原子數為2〜U 基之中,碳數為2〜22的醯基,可為脂肪族基,亦▲醯 丙基,並無特別限定,可為單一化合物,亦可為兩種=烯 201139461

present invention relates to a deuterated cellulose film, a polarizing plate using the deuterated cellulose film, and a liquid crystal display device. In particular, the present invention relates to a deuterated cellulose film which is used as a polarizing plate protective film which can improve the durability of a polarizing plate under high temperature and high humidity in combination with a polarizing plate, and the use of the deuterated cellulose film. Polarizer and liquid crystal display device. [Prior Art] The use of a liquid crystal display device as an image display device that consumes less power and saves space has been expanding year by year. Previously, the liquid crystal display device has a large disadvantage that the viewing angle of the display image is large, but a wide viewing angle liquid crystal mode such as a Vertical Alignment (VA) mode has been put into practical use, thereby requiring a high-quality picture such as a television. Demand for liquid crystal display devices is rapidly expanding, such as the market or the market where outdoor lighting is required. The basic configuration of the liquid crystal display device is such that a polarizing plate is provided on both sides of the liquid crystal cell. The polarizing plate is responsible for the passage of only the light of the polarizing surface in the fixed direction. The performance of the liquid crystal display device is greatly affected by the performance of the polarizing plate. The polarizing plate generally comprises a polarizer and a transparent protective film. The polarizer comprises a polyvinyl alcohol film or the like which adsorbs iodine or a dye, and the transparent protective film is bonded to both sides of the front and back of the polarizer. The cellulose-deposited cellulose film represented by cellulose acetate is widely used as a polarizing plate protective film because it has high transparency and can easily ensure adhesion to polyethylene glycol used in a polarizer. In recent years, the actual situation is that high-quality images are required when the liquid crystal display device is placed outdoors under high temperature and high humidity, and polarized light is required. 4 201139461 Protective film is improved to polarize under high temperature and high humidity when combined with a polarizer. Board durability. First, from the above viewpoint, the cellulose-coated cellulose film which is generally used as a protective film for a polarizing plate requires high transparency (low haze), good moisture permeability (although high but not too low), and good optical properties. Previously it was adjusted to meet performance by adding a specific plasticizer. However, as a representative plasticizer, a carboxylic acid such as a diphenyl phosphate (Triphenyl Phosphate) is sublimed in a drying step during film formation of a deuterated cellulose film, and is attached to a manufacturing line. Contaminants fall onto the membrane causing problems such as planar failure. Further, in addition to this problem, from the viewpoint of providing an environmentally-friendly polarizing plate protective film and a method for producing the same, it is also required to use no ester as a plasticizer for the bismuth fiber octane film. On the other hand, various compounds are known as plasticizers which can be added to other modifiers other than deuterated cellulose, and it has been known from the past that saccharides and derivatives thereof can be added as a plasticizer. . For example, in the patent text = Zhong Kee, by adding galactose as a plasticizer to a plastic containing the powder and the cellulose, it is excellent in environmental properties and environmentally friendly. Rotation and machine = in the use of plasticizers for cellulose enamels for optical films, sugars and "hess are also suitable. Among the bribes and their targets, sugar and vinegar compounds are known. For example, In the special dispersion 2, the degree of substitution is 59.5% (the total thiol substitution degree is about the vinegar plasticizer derived from the hexa gamma (ice _ lose less 5__^= = In Patent Document 3, phase two = 201139461 cellulose acetate having an ethyl ketone substitution degree of 2.5, and a plasticizer obtained by esterification of a hydroxyl group of a saccharide of 8 〇 0 / 〇 to 99% (refer to the literature) [〇〇32], [〇115], [0134]). In Patent Document 4, a cellulose having a total thiol substitution degree of 2.1 to 2.7 is used, and all of the hydroxyl groups of the saccharide are used. A plasticizer which is partially esterified' is understood to be a plasticizer obtained by 100% esterification of a hydroxyl group of a sugar ester compound actually used (refer to the exemplified compound 1 to the exemplified compound 1). In Patent Document 5, several kinds of sugar ester compounds having different degrees of substitution are mixed for use as plasticization with respect to deuterated cellulose having a total thiol substitution degree of 2.7 to 2.95. The sugar ester compound is a sweet and sour compound obtained by partially acetating a monosaccharide to a disaccharide group (refer to the document [0393], exemplified by the compound 3 to the exemplified compound 6, the exemplified compound 9, and the exemplified compound 18, [Table 3] to [Table 6] and the like. However, in these documents, only the use examples of the sugar ester compound having a relatively high degree of ester substitution are disclosed, particularly in the case of mixing and using several sugar esters having different degrees of substitution. In Patent Document 5 of the compound, only a form in which the addition ratio of the low-substituted sugar ester compound is extremely small is disclosed. Further, in any of the documents, the total thiol substitution degree of the cellulose-deuterated cellulose is not described (especially An example of the relationship between the range of the ethyl thiol substitution degree and the degree of ester substitution of a sugar ester compound has been studied. That is, the degree of substitution and sugar ester of the deuterated cellulose (especially cellulose acetate) has not been revealed.

Obtained from ~8.0 aliphatic diol. Further, it is also preferably obtained from a mixture of an aromatic dicarboxylic acid and at least one aliphatic dicarboxylic acid, and at least one aliphatic diol having an average carbon number of from 2.5 to 8.0. The calculation of the average carbon number of the dicarboxylic acid residue and the above dicarboxylic acid residue is carried out individually as a monohydric alcohol residue. The value calculated by multiplying the composition ratio (mole fraction) of the above dicarboxylic acid residue by a number is set as an average carbon number, for example, #% Mohr/^ adipic acid residue and orthobenzene When the diterpene acid residue is composed, the average carbon number becomes. Further, in the case of the above diol residue, the average carbon number of the diol residue is set such that the composition ratio of the diol residue (the molar fraction is multiplied by the calculated value, such as 'when by 5 〇 mole When the % ethylene glycol 5 〇 mol% of the 1,2-propanediol residue is constituted, the average carbon number of the poly-carbon condensed ester is preferably 5 (^, more preferably 700 to 1200). If the polycondensation vinegar is above _, the volatility becomes low, and it is not easy to produce a cataract or step (4) when the extension is caused by sublimation under high temperature conditions, and if it is below the test, then It is not easy to produce bleed out during film formation and during heating and extension. The number average molecular weight of the method can be reduced by gel permeation chromatography, and the broach is not at the end. The end of the polystyrene polyol Μ book t, it is difficult to measure the excess acetic acid and the amount of potassium hydroxide (mg) after the polyacetate acetonitrile. 201139461 10.0 The mixture of no-two thieves is preferably used as a di-decanoic acid of more than 5, preferably a dicarboxylic acid component, having a carbon number of 5 5 or more preferably 5.6 to 8. If the plates are both 5.5 or more, the average yield of the (4) long-lasting right-key is 1 G or less, and the compatibility of the cis-cellulose is excellent, and it can be prevented from being escaping in the riding process. The aromatic dicarboxylic acid residue is contained in the polycondensed 5-anthracene obtained from the octa- i-alcohol and the tri-alcoholic acid. The term 'residue' in the present specification means polycondensation S. The partial structure of the present invention is a partial structure having a single-frequency of (4) silk condensation. For example, the di(tetra) residue formed by a Wei HOOC-R-COOH is -OC-R-CO- The ratio of the aromatic dicarboxylic acid residue of the condensed ester is preferably 40 mol% or more, more preferably 4 〇 mol% to 95 mol%, and the ratio of the aromatic dicarboxylic acid residue is set to 4 〇 m 〇. 1% or more, a bismuth-based film which exhibits sufficient optical anisotropy can be obtained, and a polarizing plate excellent in durability can be obtained. When the % curry% or less is satisfied, the compatibility of the cellulose ester is excellent. It is also difficult to cause bleed out during film formation and heating extension of the fluorinated cellulose film. As an aromatic urethane which can be used for the formation of the above polycondensation ester-based hydrophobizing agent Examples of the acid include phthalic acid, terephthalic acid, m-dicarboxylic acid, 1,5-naphthoic acid, iota-4-naphthoic acid, naphthalene dicarboxylic acid, and 2-naphthalene dicarboxylic acid.

Preferably, at least one of the anthracene dioxime group, the p-dibenzoic acid residue, and the isophthalic acid residue is preferably an phthalic acid residue or a terephthalic acid residue. At least one of the compounds, and more preferably a terephthalic acid residue. In the case of mixing in the formation of the above-mentioned polycondensation ester, the use of the aromatic dicarboxylic acid as the aromatic dicarboxylic acid can be used to form a film with a deuterated cellulose. It is also difficult to produce a deuterated cellulose film at the time of heating and elongation. Further, the aromatic dicarboxylic acid may be used singly or in combination of two or more kinds. When two types are used, it is preferred to use 'acid and p-dicarboxylic acid. It is preferable to use a combination of two kinds of aromatic diacids of phthalic acid and terephthalic acid to soften the polycondensed vinegar at normal temperature. The amount of the terephthalic acid residue in the dicarboxylic acid residue of the above polycondensation ester is preferably 40 mol% to 1 〇〇 m〇i%. 3 ^ By setting the terephthalic acid residue ratio to 4 〇 m 〇 1% or more, a cellulose optical film having a sufficient optical anisotropy of '4 is obtained. An aliphatic diterpene acid residue is contained in the ester obtained from the diol and the diremediate acid containing an aliphatic diremediate acid. As the aliphatic & '', which can form the above-mentioned polycondensation ester-based hydrophobizing agent, for example, oxalic acid m-lan, cis-butan ^ 32 201139461 anti-butadiate = diacid, glutaric acid, adipic acid, pimelic acid And suberic acid, azelaic acid, decanoic acid, dodecanedicarboxylic acid or 1> 4-cyclohexanedicarboxylic acid.

The average carbon number of the post-aliphatic dicarboxylic acid residue is preferably from 5.5 to 10.0, more preferably 5.5 8.0, still more preferably from 55 to 7 Å. If the average carbon number of the aliphatic di-retensive acid residue is less than the cut, the heating reduction of the compound can be reduced and the step caused by the bleeding during the drying of the cellulose network can be prevented from being the cause of the failure. produce. Further, when the number of carbon residues of the lipid-bis-acid retardation is 5.5 or more, the compatibility is excellent, and precipitation of the polycondensation ester is less likely to occur, which is preferable. In the case of the second Xiangsa 'i ^ silk condensation S, it is possible to use two kinds of aliphatic amber shafts. When two types are used, it is preferred to use an acid. It is preferred to use an acid in the mixing at the time of forming the polycondensation. The idea of an aliphatic two-passibility can be preferred to the desired value 'in the second phase of the brewing cellulose: two or three acids and aromatics - preferably using the two aliphatics of each species 33 201139461 = Family second. The value of 1 in the average = number of the dicarboxylic acid residue of the organic dicarboxylic acid residue can make the content of the aromatic dinuclear residue become more uniform and improve the durability of the polarizer. The diol residue is contained in the diol and the diNide containing the ruthenium. Θ θ In the present specification, the diol residue formed by the diol ΗΟ κ κ 〇Η -0 is -0-R-0-.

The above-mentioned polycondensation ester is preferably a fatty alcohol residue having an average carbon number of 2.5 to 7.0, more preferably an aliphatic diol residue having an average carbon number of 2.5 to 4.0. When the average carbon number of the aliphatic diol residue is less than 7 〇, the compatibility with the cellulose is improved, and the amount of heat loss of the β substance is hardly increased, and the brewing is hard to occur. The step of drying the cellulose network is considered to be the cause of the problem. Further, when the average carbon number of the aliphatic-alcohol residue is 25 or more, the synthesis is easy. The aliphatic diol which can form the above-mentioned polycondensation ester-based hydrophobizing agent may, for example, be an alkyl diol or an alicyclic diol, and is preferably, for example, a diol or a 1,2-propanediol. 1,3-propanediol, 1,2-butanediol, υ-butanediol, 2-hydrazino-1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, 2,2_ Methyl propanol (neopentyl glycol), 2,2-diethyl-1,3-propanediol (3,3-di-methylpentane), 2-n-butyl-2-ethyl-1 , 3-propanediol (3,3_-light methyl heptane), 3-mercapto-1,5-pentanediol, 1,6-hexanediol, 2,2,4-34 201139461 monomethyl-1 , 3-pentanediol, 2-ethyl_ι, 3-hexanediol, 2_, its alcoholic decanediol, U0-decanediol, (3)·Eight-fired _^=octane=alcohol, cyclohexane Two p alcohol and the like.

Description of the Invention: [Technical Field] The present invention relates to a deuterated cellulose crucible, using the deuterated A polarizing plate of a cellulose film and a liquid crystal display device. In particular, the present invention relates to a deuterated cellulose film which is used as a polarizing plate protective film which can improve the durability of a polarizing plate under high temperature and high humidity in combination with a polarizing plate, and a polarizing film using the deuterated cellulose film. Board and liquid crystal display device. [Prior Art] The liquid crystal display device is an image display device that consumes less power and is space-saving, and its saturation is expanding year by year. Previously, the disadvantage of the liquid crystal display translocation is that the viewing angle of the display image is large, but the wide viewing angle liquid crystal mode such as the vertical alignment (... Alignment, VA) mode has been put into practical use, thereby requiring high quality such as television. The market for images or the market that is required to be installed in the outdoor market's demand for liquid crystal display devices is rapidly expanding. The basic configuration of the liquid crystal display device is such that a polarizing plate is provided on both sides of the liquid crystal cell. The polarizing plate is responsible for passing only the light of the deflecting surface in the fixed direction, and the performance of the liquid crystal display device is greatly affected by the performance of the polarizing plate. The polarizing plate generally comprises a polarizer and a transparent protective film. The polarizer comprises a polyvinyl alcohol film or the like which adsorbs iodine or a dye, and the transparent protective film is bonded to both sides of the front and back of the polarizer. The cellulose-deposited cellulose film represented by cellulose acetate is widely used as a protective film for a polarizing plate because it has high transparency and can easily ensure adhesion to polyvinyl alcohol used in a polarizer. In recent years, the actual situation is that when the liquid crystal display device is installed outdoors under high temperature and high humidity, the image of the high product f is also required, and the polarized light is required for the 201139461 correction period: July 18, 100 is the Chinese manual No. 100112643 The scratch-free correction of the protective film of the board improves the durability of the polarizing plate under high temperature and high humidity when combined with the polarizer. First, from the above viewpoints, the 醯$cellulose film generally used as a protective film for a polarizing plate requires high transparency (low turbidity), good moisture permeability (although high but not too low), and good optical properties. Previously it was adjusted to meet performance by adding a specific plasticizer. However, phosphates such as Triphenyl PhGsphate (TPP), which is a typical plasticizer, are sublimed in a drying step when filming a cellulose-coated cellulose film, and are attached to a manufacturing line. In addition to this problem, it is also required to use a plasticizer which does not use a phosphoric acid film, from the viewpoint of providing an environmentally-friendly polarizing plate protective film and a manufacturing method. In the case of the plasticizer which can be added to the cellulose fiber, various compounds are known, and the sugar and its derivative can be added as a plasticizer. For example, it is described in 2 that by providing galactose containing starch and carboxymethylcellulose = 2; a plasticizer, it is excellent in biodegradable physicochemical properties and the ring is simple. Jobs and Machines It is also known that plasticizers and derivatives thereof for use in cellulose membranes for optical films are suitable for the production of sweet and sour compounds in sugars and their derivatives. For example, in the patent document, the degree of use is 59.5% (the total thiol group is substituted with an ester of a sugar alcohol derived from a hexacarbase (a total of at least 5 sucrose of a sugar alcohol). Plasticizer. On 5 201139461 Revised flood season: July 18th, 2001, No. 100112643 Chinese manual, no underline correction, cellulose acetate with a degree of substitution of 2.5, using enzyme base 8% to 99% of the plasticizer obtained by S (refer to the literature [0032], [〇115], [0134]). In Patent Document 4, the degree of substitution with respect to the total base is described. For the deuterated cellulose of 2.1 to 2.7, a plasticizer obtained by esterifying all or part of the hydroxyl group of the saccharide is used, but it can be understood that the hydroxyl group of the sugar ester compound actually used is 100% esterified. Plasticizer (refer to the literature exemplifying compound 1 to exemplified compound 10, etc.). In Patent Document 5, several kinds of sugar ester compounds having different degrees of substitution are used for deuterated cellulose having a total thiol substitution degree of 2.7 to 2.95. Mixed to be used as a plasticizer, the above sugar ester compound is a partial esterification of a hydroxyl group of a monosaccharide to a trisaccharide A sugar ester compound (refer to the document [0393], exemplified by the compound 3 to the exemplified compound 6, the exemplified compound 9, and the exemplified compound 18' [Table 3] to [Table 6], etc. However, in these documents, substantially Only the use examples of the sugar ester compound having a relatively high degree of ester substitution are disclosed, and in particular, in Patent Document 5 in which several sugar ester compounds having different degrees of substitution are mixed, only the addition ratio of the sugar ester compound having a low degree of substitution is revealed to be very small. Further, in any of the literatures, there is no description of the relationship between the degree of total thiol substitution (particularly the degree of substitution of acetylation) of deuterated cellulose and the degree of ester substitution of sugar ester compounds. The example, that is, does not reveal the optimum combination of the degree of substitution of the thiol group of cellulose (especially cellulose acetate) with the degree of ester substitution of the sugar ester compound. In addition, in these documents, The durability of the polarizing plate under high temperature and high humidity when the obtained polarizing plate protective film and the polarizing plate are combined is studied.
