- the addition amount of the organic solvent is not particularly limited, but it is preferably 100 to 100,000 parts by mass with respect to 100 parts by mass of the composition other than the organic solvent. The reason is that when the addition amount is less than 100 parts by mass, it may be difficult to adjust the viscosity of the curable resin composition. On the other hand, when the addition amount exceeds 100,000 parts by mass, the curable resin composition may be difficult to adjust.

- the other low refractive index films exceed 1.45. It may be a value.
- the refractive index difference with respect to the high refractive index layer is a value of 0.05 or more because a better antireflection effect can be obtained.
- the reason for this is that if the difference in refractive index between the low refractive index layer and the high refractive index layer is less than 0.05, the synergistic effect of these antireflective film layers cannot be obtained, and instead the antireflective effect. This is because there is a case where the value decreases. Therefore, it is more preferable to set the difference in refractive index between the low refractive index layer and the high refractive index layer to a value within the range of 0.:! To 0.5. More preferably, the value is within the range.
- the thickness of the low refractive index layer is not particularly limited, and is preferably 50 to 300 nm, for example.

This is because these resins can form a strong thin film as the high refractive index layer, and as a result, the scratch resistance of the antireflection film can be remarkably improved.
- the refractive index of these resins alone is usually 1.45 to: 1.62, which may not be sufficient to obtain high antireflection performance. Therefore, it is more preferable to blend high refractive index inorganic particles, for example, metal oxide particles.

- the thickness of the high refractive index layer is not particularly limited, but is preferably 50-30, OOOnm, for example.
- the reason for this is that when the thickness of the high refractive index layer is less than 50 nm, when combined with the low refractive index layer, the antireflection effect may decrease the adhesion to the substrate, while the thickness This is because if the thickness exceeds 30, OOOnm, optical interference may occur and the antireflection effect may be reduced.

Etc.
- the thickness of the hard coat layer is not particularly limited, but is preferably set to:! To 50 ⁇ 1 to: more preferably set to ⁇ ⁇ , .
- the reason for this is that when the thickness of the hard coat layer is less than ⁇ m, the adhesion of the antireflection film to the substrate may not be improved, whereas the thickness exceeds 50 xm. This is because it may be difficult to form a uniform layer.
- the conductive layer is as described above and will not be described in detail here, by providing the conductive layer, conductivity is imparted to the stacked body, and static electricity is generated and dust and the like are prevented from attaching.

明 細 書 Specification
反射防止膜 Anti-reflection coating
技術分野 Technical field
[0001] 本発明は、反射防止膜に関する。より詳細には、帯電防止性、耐擦傷性及び耐汚 染性に優れた反射防止膜に関する。 [0001] The present invention relates to an antireflection film. More specifically, the present invention relates to an antireflection film excellent in antistatic properties, scratch resistance and stain resistance.
背景技術 Background art
[0002] 液晶表示パネル、冷陰極線管パネル、プラズマディスプレー等の各種表示パネル において、外光の映りを防止し、画質を向上させるために、低屈折率性、耐擦傷性、 塗工性及び耐汚染性に優れた硬化物からなる低屈折率層を含む反射防止膜が求 められている。 In various display panels such as liquid crystal display panels, cold cathode ray tube panels, plasma displays, etc., in order to prevent reflection of external light and improve image quality, low refractive index properties, scratch resistance, coating properties, There is a demand for an antireflection film including a low refractive index layer made of a cured product having excellent contamination properties.
これら表示パネルにおいては、付着した指紋、埃等を除去するため表面をエタノー ル等を含侵したガーゼで拭くことが多ぐ耐擦傷性が求められている。また、付着した 指紋、埃等が容易に拭き取れる耐汚染性も求められてレ、る。 These display panels are required to have scratch resistance that is often wiped with gauze impregnated with ethanol or the like in order to remove attached fingerprints, dust, and the like. There is also a need for anti-contamination that can easily wipe off attached fingerprints and dust.
特に、液晶表示パネルにおいては、反射防止膜は、偏光板と貼り合わせた状態で 液晶ユニット上に設けられている。また、基材としては、例えば、トリァセチルセルロー ス等が用いられているが、このような基材を用いた反射防止膜では、偏光板と貼り合 わせる際の密着性を増すために、通常、アルカリ水溶液でケン化を行う必要がある。 従って、液晶表示パネルの用途においては、耐久性において、特に、耐アルカリ性 に優れた反射防止膜が求められている。 In particular, in a liquid crystal display panel, the antireflection film is provided on the liquid crystal unit in a state of being bonded to a polarizing plate. In addition, as the base material, for example, triacetyl cellulose is used, but in the antireflection film using such a base material, in order to increase the adhesion when bonded to the polarizing plate, Usually, it is necessary to saponify with an alkaline aqueous solution. Therefore, in applications of liquid crystal display panels, there is a demand for an antireflection film excellent in alkali resistance, particularly in durability.
[0003] 反射防止膜の低屈折率層用材料として、例えば、水酸基含有含フッ素重合体を含 むフッ素樹脂系塗料が知られている(例えば、特許文献:!〜 3)。 [0003] As a material for a low refractive index layer of an antireflection film, for example, a fluororesin-based paint containing a hydroxyl group-containing fluoropolymer is known (for example, Patent Documents:! To 3).
しかし、このようなフッ素樹脂系塗料では、塗膜を硬化させるために、水酸基含有含 フッ素重合体と、メラミン樹脂等の硬化剤とを、酸触媒下、加熱して架橋させる必要が あり、加熱条件によっては、硬化時間が過度に長くなり、使用できる基材の種類が限 定されてしまうという問題があった。 However, in such a fluororesin-based paint, it is necessary to heat and crosslink a hydroxyl group-containing fluoropolymer and a curing agent such as melamine resin in the presence of an acid catalyst in order to cure the coating film. Depending on the conditions, there is a problem that the curing time becomes excessively long and the types of base materials that can be used are limited.
また、得られた塗膜についても、耐候性には優れているものの、耐擦傷性や耐久性 に乏しいという問題があった。
[0004] そこで、上記の問題点を解決するため、少なくとも 1個のイソシァネート基と少なくと も 1個の付加重合性不飽和基とを有するイソシァネート基含有不飽和化合物と水酸 基含有含フッ素重合体とを、イソシァネート基の数/水酸基の数の比が 0. 01〜: 1. 0 の割合で反応させて得られる不飽和基含有含フッ素ビニル重合体を含む塗料用組 成物が提案されている(例えば、特許文献 4)。 Also, the obtained coating film has a problem that it has poor weather resistance but poor scratch resistance and durability. [0004] Therefore, in order to solve the above problems, an isocyanate group-containing unsaturated compound having at least one isocyanate group and at least one addition-polymerizable unsaturated group, and a hydroxyl group-containing fluorine-containing polymer. A composition for coatings containing an unsaturated group-containing fluorinated vinyl polymer obtained by reacting a polymer with an isocyanate group at a ratio of the number of isocyanate groups to the number of hydroxyl groups of 0.01 to 1.0 is proposed. (For example, Patent Document 4).
[0005] しかし、上記特許文献 4では、不飽和基含有含フッ素ビニル重合体を調製する際に[0005] However, in Patent Document 4 described above, when preparing a fluorine-containing vinyl polymer containing an unsaturated group,
、水酸基含有含フッ素重合体の全ての水酸基を反応させるのに十分な量のイソシァ ネート基含有不飽和化合物を用いず、積極的に当該重合体中に未反応の水酸基を 残存させるものであった。 In addition, an isocyanate group-containing unsaturated compound in an amount sufficient to react all the hydroxyl groups of the hydroxyl group-containing fluoropolymer was not used, and unreacted hydroxyl groups were actively left in the polymer. .
このため、このような重合体を含む塗料用組成物は、低温、短時間での硬化を可能 とするものの、残存した水酸基を反応させるために、メラミン樹脂等の硬化剤をさらに 用いて硬化させる必要があった。さらに、上記公報で得られた塗膜は、塗工性、耐擦 傷性についても十分とはいえないという課題があった。 Therefore, a coating composition containing such a polymer can be cured at a low temperature in a short time, but is further cured using a curing agent such as a melamine resin in order to react the remaining hydroxyl group. There was a need. Furthermore, the coating film obtained in the above publication has a problem that it is not sufficient in coating property and scratch resistance.

発明を実施するための最良の形態 BEST MODE FOR CARRYING OUT THE INVENTION
[0011] 本発明の反射防止膜の実施形態について以下説明する。 [0011] An embodiment of the antireflection film of the present invention will be described below.
[0012] 1.導電層 [0012] 1. Conductive layer
本発明の反射防止膜における導電層は帯電防止層として機能する。気相重合によ り形成される導電層は、例えば特開 2003— 82105号公報に記載された方法等によ つて製造することができ、具体的には導電性ポリマーから形成することができる。即ち 、ベース層に酸化剤を数 μ ΐη単位の厚さで塗布し、単量体 (モノマー)を気体状態で 酸化剤塗膜と接触させることで、重合を進行させ、導電性ポリマー膜を基材上に形成 する。この際、接着力を向上させる意味で、有機溶剤とともにポリウレタン、ポリ塩化ビ ニル、ポリビエルアルコール、メチルセルロース、キトサン等の高分子を併用すること も可能である。 The conductive layer in the antireflection film of the present invention functions as an antistatic layer. The conductive layer formed by gas phase polymerization can be produced by, for example, the method described in JP-A-2003-82105, and can be specifically formed from a conductive polymer. In other words, an oxidant is applied to the base layer with a thickness of several μΐη units, and the monomer (monomer) is brought into contact with the oxidant coating film in a gaseous state, whereby the polymerization proceeds and the conductive polymer film is formed as a base. Form on the material. At this time, in order to improve the adhesive strength, it is also possible to use a polymer such as polyurethane, polyvinyl chloride, polyvinyl alcohol, methylcellulose, chitosan together with an organic solvent.
本発明では、酸化剤が塗布されたベース層上で、単量体を気相重合させて導電性
ポリマーからなる導電層を形成するが、この際の反応温度は、 0〜140°Cであることが 好ましレ、。以下、より詳細に重合方法を説明するが、本発明はこれに限定されない。 In the present invention, the monomer is vapor-phase polymerized on the base layer coated with the oxidizing agent to conduct the A conductive layer made of a polymer is formed, and the reaction temperature at this time is preferably 0 to 140 ° C. Hereinafter, the polymerization method will be described in more detail, but the present invention is not limited thereto.
[0013] 具体的には、まず第 1段階として、ベース層の表面に 0. 5〜: 10質量%の酸化剤を 数 z m単位で塗布する。酸化剤として例えば CuCl、トルエンスルホン酸鉄(ΠΙ)、過 [0013] Specifically, as a first step, 0.5 to 10% by mass of an oxidizing agent is applied to the surface of the base layer in units of several zm. Examples of oxidizing agents include CuCl, iron toluenesulfonate (ΠΙ),

物が単独又は組合せで使用できる。この際の溶剤条件は使用ベース層の種類によ つて異なるが、例えば、メチルアルコール、 2_ブチルアルコール、ェチルセ口ソルブ 、エチルアルコール、シクロへキサン、アセトン、ェチルアセテート、トルエン及びメチ ルェチルケトンから選択される有機溶剤を用いることができる。これらは、単独又は 2 種以上混合して用いることができ、例えば、メチルアルコール、 2_ブチルアルコール 及びェチルセ口ソルブから構成される有機溶剤を 7 : 2 : 1、 6 : 2 : 2、 6 : 3 : 1、 5 : 3 : 2等 の割合で混合して用いる。酸化剤が塗布されたベース層は、酸化剤の分解を考慮し 、 80°C以下の熱風乾燥機で乾燥させる。 Things can be used alone or in combination. The solvent conditions at this time vary depending on the type of base layer used. The organic solvent used can be used. These can be used alone or in combination of two or more. For example, an organic solvent composed of methyl alcohol, 2_butyl alcohol and ethyl acetate sorb 7: 2: 1, 6: 2: 2, 6: Mix at a ratio of 3: 1, 5: 3: 2, etc. The base layer to which the oxidizing agent is applied is dried with a hot air dryer at 80 ° C. or lower in consideration of decomposition of the oxidizing agent.
[0014] 次に第 2段階として、酸化剤で塗布されたベース層に、ピロール、チォフェン、フラ ン、セレノフェン及び 3, 4—エチレンジォキシチォフェン並びにこれらの誘導体から なる群から選択される単量体を、気化して接触させ、ベース層の表面で重合反応を 行う。この際、単量体を気化させる方法としては、密閉されたチャンバ一内で単量体 を 0〜: 140°Cで蒸留させる方法と、 CVD (Chemical Vapor Deposition)による方法 等が挙げられる。このとき、温度条件と反応時間を調整することが好ましぐ重合反応 は、 10秒〜 40分程度行なわれ、一般的には、単量体の種類に応じて変化するが、 膜厚及び表面抵抗値等が目標値に達するまで行なう。 [0014] Next, as a second step, the base layer coated with the oxidizing agent is selected from the group consisting of pyrrole, thiophene, furan, selenophene, 3,4-ethylenedioxythiophene, and derivatives thereof. The monomer is vaporized and brought into contact, and a polymerization reaction is performed on the surface of the base layer. At this time, examples of the method for vaporizing the monomer include a method in which the monomer is distilled at 0 to 140 ° C. in a sealed chamber, a method by CVD (Chemical Vapor Deposition), and the like. At this time, it is preferable to adjust the temperature conditions and the reaction time, and the polymerization reaction is carried out for about 10 seconds to 40 minutes, and generally varies depending on the type of monomer. Repeat until the resistance value reaches the target value.
[0015] 次に第 3段階として、重合が完了した後、未反応の単量体及び酸化剤を除去する ための洗浄工程を行う。この際の使用溶剤としては、通常メタノール等のアルコール 類を用レ、、場合によっては水で洗浄することもできる。 [0015] Next, as a third stage, after the polymerization is completed, a washing step is performed to remove unreacted monomers and oxidizing agents. As the solvent used in this case, alcohol such as methanol is usually used, and in some cases, it can be washed with water.
[0016] 上記のような一連の工程は、段階的又は連続的に行うことができ、単量体の重合か ら導電膜の形成までは、一連の作業工程で処理することができる。得られた導電性 ポリマーフィルムは、ベース層に対する密着性が良好であり、アルコール溶剤に対す る耐性も十分である。
[0017] 導電層の膜厚は、:!〜 2000nmであることが好ましい。 lnm未満の膜厚では、ピン ホール等が発生しやすぐ膜形成が困難であり、また、表面抵抗も大きくなり、帯電防 止性に劣る恐れがある。また、 2000nmを超える膜厚では、表面抵抗は良好である 、透明性、色調が著しく劣り、反射防止膜としては使用困難な場合がある。特に好 ましい膜厚は、透明性、色調、表面抵抗のバランスの観点から、 5〜300nmである。 また、導電層の表面抵抗は通常 102 Ω /口〜 1012 Ω /口である。 [0016] The series of steps as described above can be performed stepwise or continuously, and from the polymerization of the monomers to the formation of the conductive film, they can be performed in a series of working steps. The obtained conductive polymer film has good adhesion to the base layer and has sufficient resistance to alcohol solvents. [0017] The thickness of the conductive layer is preferably:! -2000 nm. If the film thickness is less than 1 nm, pinholes or the like are generated, and it is difficult to form a film immediately. Further, the surface resistance is increased and the antistatic property may be deteriorated. On the other hand, when the film thickness exceeds 2000 nm, the surface resistance is good, but the transparency and color tone are extremely inferior, making it difficult to use as an antireflection film. A particularly preferred film thickness is 5 to 300 nm from the viewpoint of the balance of transparency, color tone, and surface resistance. The surface resistance of the conductive layer is usually 10 2 Ω / port to 10 12 Ω / port.

[0047] 尚、構造単位(d)の含有率は、構造単位(a)、(b)及び(c)の合計 100モル部に対 して、 0. 1〜: 10モル部とすることが好ましい。この理由は、含有率が 0. 1モル部未満 になると、硬化後の塗膜の表面滑り性が低下し、塗膜の耐擦傷性が低下する場合が あるためであり、一方、含有率が 10モル部を超えると、水酸基含有含フッ素重合体の 透明性に劣り、コート材として使用する際に、塗布時にハジキ等が発生し易くなる場 合があるためである。 [0047] The content of the structural unit (d) may be 0.1 to 10 mole parts with respect to a total of 100 mole parts of the structural units (a), (b) and (c). preferable. The reason for this is that when the content is less than 0.1 mol part, the surface slipperiness of the coated film after curing is lowered, and the scratch resistance of the coated film may be lowered. When the amount exceeds 10 mol parts, the transparency of the hydroxyl group-containing fluoropolymer is inferior, and when used as a coating material, repelling or the like may easily occur during coating.

[0054] 尚、構造単位(a)、(b)及び(c)の合計 100モル部に対して、構造単位 (f)の含有 率を、 0.:!〜 5モル部とすることが好ましい。この理由は、含有率が 0. 1モル部以上 になると、水酸基含有含フッ素重合体の溶剤への溶解性が向上し、一方、含有率が 5モル部以下であれば、硬化性樹脂組成物の粘着性が過度に増加せず、取り扱い が容易になり、コート材等に用いても耐湿性が低下しないためである。 [0054] The content of the structural unit (f) is preferably 0.:! To 5 mol parts with respect to a total of 100 mol parts of the structural units (a), (b) and (c). . The reason is that when the content is 0.1 mol part or more, the solubility of the hydroxyl group-containing fluoropolymer in the solvent is improved. On the other hand, when the content is 5 mol part or less, the curable resin composition is used. This is because the adhesiveness of the film does not increase excessively, handling becomes easy, and moisture resistance does not decrease even when used as a coating material.
また、このような理由により、構造単位 (f)の含有率を、構造単位(a)、(b)及び (c) の合計 100モノレ咅 こ対して、 0. :!〜 3モノレ咅 Bとするの力 Sより好ましく、 0. 2〜3モノレ咅 とするのがさらに好ましい。 For this reason, the content of the structural unit (f) is changed from 0.:!

[0055] (vi)分子量 [0055] (vi) Molecular weight
水酸基含有含フッ素重合体は、ゲルパーミエーシヨンクロマトグラフィーで、テトラヒ ドロフランを溶剤として測定したポリスチレン換算数平均分子量が 5, 000-500, 00 0であることが好ましい。この理由は、数平均分子量が 5, 000未満になると、水酸基 含有含フッ素重合体の機械的強度が低下する場合があるためであり、一方、数平均 分子量が 500, 000を超えると、後述する硬化性樹脂組成物の粘度が高くなり、薄膜 コーティングが困難となる場合があるためである。 The hydroxyl group-containing fluoropolymer preferably has a polystyrene equivalent number average molecular weight of 5,000 to 500,000 as measured by gel permeation chromatography using tetrahydrofuran as a solvent. The reason for this is that when the number average molecular weight is less than 5,000, the mechanical strength of the hydroxyl group-containing fluoropolymer may be lowered. On the other hand, when the number average molecular weight exceeds 500,000, it will be described later. This is because the viscosity of the curable resin composition becomes high and thin film coating may be difficult.
また、このような理由により、水酸基含有含フッ素重合体のポリスチレン換算数平均 分子量を 10, 000〜300, 000とするの力 Sより好ましく、 10, 000〜: 100, 000とする のがさらに好ましい。 For these reasons, the hydroxyl-containing fluoropolymer has a polystyrene equivalent number average molecular weight of 10,000 to 300,000, more preferably S, more preferably 10,000 to 100,000. .
[0056] (3)反応モル比 [0056] (3) Reaction molar ratio
エチレン性不飽和基含有含フッ素重合体は、上述した、 1個のイソシァネート基と、 少なくとも 1個のエチレン性不飽和基とを含有する化合物と、水酸基含有含フッ素重 合体とを、イソシァネート基 Z水酸基のモル比が 1. 1〜: 1. 9の割合で反応させて得 られる。この理由は、モル比が 1. 1未満になると耐擦傷性及び耐久性が低下する場 合があるためであり、一方、モル比が 1. 9を超えると、硬化性樹脂組成物の塗膜のァ ルカリ水溶液浸漬後の耐擦傷性が低下する場合があるためである。 The ethylenically unsaturated group-containing fluorine-containing polymer comprises the above-mentioned compound containing one isocyanate group, at least one ethylenically unsaturated group, and a hydroxyl group-containing fluorine-containing polymer. It is obtained by reacting at a molar ratio of hydroxyl group of 1.1 to 1.9. The reason for this is that if the molar ratio is less than 1.1, the scratch resistance and durability may be lowered. On the other hand, if the molar ratio exceeds 1.9, the coating film of the curable resin composition may be used. This is because the scratch resistance after immersion in an alkaline solution may be reduced.
また、このような理由により、イソシァネート基 Z水酸基のモル比を、 1. 1〜: 1. 5とす るのが好ましぐ 1. 2〜1.5とするのがより好ましい。
[0057] 硬化性樹脂組成物における、(A)成分の添カ卩量については、特に制限されるもの ではないが、有機溶剤以外の組成物全量に対して通常 1〜95質量%である。この理 由は、添加量が 1質量%未満となると、硬化性樹脂組成物の硬化塗膜の屈折率が高 くなり、十分な反射防止効果が得られない場合があるためであり、一方、添加量が 95 質量%を超えると、硬化性樹脂組成物の硬化塗膜の耐擦傷性が得られなレ、場合が あるためである。 For this reason, the molar ratio of the isocyanate group Z hydroxyl group is preferably 1.1 to 1.5, and more preferably 1.2 to 1.5. [0057] The amount of the additive (A) added in the curable resin composition is not particularly limited, but is usually 1 to 95% by mass with respect to the total amount of the composition other than the organic solvent. The reason for this is that when the addition amount is less than 1% by mass, the refractive index of the cured coating film of the curable resin composition increases, and a sufficient antireflection effect may not be obtained. This is because if the addition amount exceeds 95% by mass, the scratch resistance of the cured coating film of the curable resin composition may not be obtained.
また、このような理由から、 (A)成分の添力卩量を 2〜90質量%とするのがより好まし く、 3〜85質量%の範囲内の値とするのがさらに好ましい。 For this reason, it is more preferable that the amount of added force of the component (A) is 2 to 90% by mass, and it is more preferable that the value is within the range of 3 to 85% by mass.

[0080] (ii)添加量 [0080] (ii) Amount added
光重合開始剤の添加量は特に制限されるものではないが、有機溶剤以外の組成 物全量 100質量部に対して、 0. 01〜20質量部とするのが好ましい。この理由は、添 加量が 0. 01質量部未満となると、硬化反応が不十分となり耐擦傷性、アルカリ水溶 液浸漬後の耐擦傷性が低下する場合があるためである。一方、光重合開始剤の添 加量が 20質量部を超えると、硬化膜の屈折率が増加し反射防止効果が低下する場 合があるためである。 The addition amount of the photopolymerization initiator is not particularly limited, but is preferably 0.01 to 20 parts by mass with respect to 100 parts by mass of the total composition other than the organic solvent. The reason for this is that when the addition amount is less than 0.01 parts by mass, the curing reaction becomes insufficient and the scratch resistance and the scratch resistance after immersion in an alkaline aqueous solution may be lowered. On the other hand, if the addition amount of the photopolymerization initiator exceeds 20 parts by mass, the refractive index of the cured film may increase and the antireflection effect may decrease.

[0083] (ii)添加量 [0083] (ii) Amount added
熱重合開始剤の添加量についても特に制限されるものではないが、有機溶剤以外 の組成物全量 100質量部に対して、 0. 01〜20質量部とするのが好ましレ、。この理 由は、添加量が 0. 01質量部未満となると、硬化反応が不十分となり耐擦傷性、アル カリ水溶液浸漬後の耐擦傷性が低下する場合があるためである。一方、光重合開始 剤の添加量が 20質量部を超えると、硬化膜の屈折率が増加し反射防止効果が低下 する場合があるためである。 The addition amount of the thermal polymerization initiator is not particularly limited, but is preferably 0.01 to 20 parts by mass with respect to 100 parts by mass of the total composition other than the organic solvent. The reason for this is that when the amount added is less than 0.01 parts by mass, the curing reaction becomes insufficient and the scratch resistance and the scratch resistance after immersion in an aqueous alkali solution may be lowered. On the other hand, when the addition amount of the photopolymerization initiator exceeds 20 parts by mass, the refractive index of the cured film increases and the antireflection effect may decrease.
また、このような理由から、有機溶剤以外の組成物全量 100質量部に対して熱重合 開始剤の添力卩量を 0. 05〜: 15質量部とするのがより好ましぐ 0. 1〜: 15質量部の範 囲内の値とするのがさらに好ましい。 For this reason, it is more preferable to set the additive amount of the thermal polymerization initiator to 0.05 to 15 parts by mass with respect to 100 parts by mass of the total composition other than the organic solvent. To: More preferably, the value is within the range of 15 parts by mass.
[0084] (E)有機溶媒 [0084] (E) Organic solvent
硬化性樹脂組成物には、さらに有機溶媒を添加することが好ましい。このように有 機溶媒を添加することにより、薄膜の反射防止膜を均一に形成することができる。こ のような有機溶媒としては、炭素数 1〜8のアルコール系、炭素数 3〜: 10のケトン系、 炭素数 3〜: 10のエステル系の有機溶媒が好ましく使用でき、メチルイソプチルケトン 、メチルェチルケトン、メタノーノレ、エタノール、 tーブタノール、イソプロパノール、プロ ピレンダリコールモノメチルエーテル、プロピレングリコールェチルエーテル、プロピレ ングリコールモノプロピルエーテル等が特に好ましい例として挙げられる。これらの有 機溶媒は一種単独又は二種以上の組み合わせで使用できる。 It is preferable to further add an organic solvent to the curable resin composition. Thus, by adding an organic solvent, a thin antireflection film can be formed uniformly. As such an organic solvent, an alcohol solvent having 1 to 8 carbon atoms, a ketone solvent having 3 to 10 carbon atoms, and an ester solvent having 3 to 10 carbon atoms can be preferably used. Methyl ethyl ketone, methanol, ethanol, t-butanol, isopropanol, propylene glycol monomethyl ether, propylene glycol ether ether, propylene glycol monopropyl ether and the like are particularly preferable examples. These organic solvents can be used singly or in combination of two or more.
[0085] 有機溶媒の添加量についても特に制限されるものではなレ、が、有機溶剤以外の組 成物 100質量部に対し、 100〜100,000質量部とするのが好ましレ、。この理由は、 添加量が 100質量部未満となると、硬化性樹脂組成物の粘度調整が困難となる場合 があるためであり、一方、添カ卩量が 100,000質量部を超えると、硬化性樹脂組成物 の保存安定性が低下したり、あるいは粘度が低下しすぎて取り扱いが困難となる場合 があるためである。
[0086] (F)添加剤 [0085] The addition amount of the organic solvent is not particularly limited, but it is preferably 100 to 100,000 parts by mass with respect to 100 parts by mass of the composition other than the organic solvent. The reason is that when the addition amount is less than 100 parts by mass, it may be difficult to adjust the viscosity of the curable resin composition. On the other hand, when the addition amount exceeds 100,000 parts by mass, the curable resin composition may be difficult to adjust. This is because the storage stability of the composition may be decreased, or the viscosity may be excessively decreased to make handling difficult. [0086] (F) Additive
硬化性樹脂組成物には、本発明の目的や効果を損なわない範囲において、光増 感剤、重合禁止剤、重合開始助剤、レべリング剤、濡れ性改良剤、界面活性剤、可 塑剤、紫外線吸収剤、酸化防止剤、帯電防止剤、シランカップリング剤、 (B)成分以 外の無機充填剤若しくは顔料、染料等の添加剤をさらに含有させることもできる。 The curable resin composition includes a photosensitizer, a polymerization inhibitor, a polymerization initiation assistant, a leveling agent, a wettability improver, a surfactant, a plasticizer, as long as the objects and effects of the present invention are not impaired. An additive such as an agent, an ultraviolet absorber, an antioxidant, an antistatic agent, a silane coupling agent, an inorganic filler other than the component (B), a pigment, and a dye may be further contained.
[0087] 次に、本発明で使用される硬化性樹脂組成物の調製方法及び硬化条件を説明す る。 [0087] Next, a preparation method and curing conditions for the curable resin composition used in the present invention will be described.
本発明で使用される硬化性樹脂組成物は、上記 (A)エチレン性不飽和基含有含 フッ素重合体及び上記 (B)成分、又は必要に応じて上記(C)成分、(D)成分、(E) 有機溶剤、及び (F)添加剤をそれぞれ添加して、室温又は加熱条件下で混合するこ とにより調製すること力 Sできる。具体的には、ミキサ、ニーダー、ボールミル、三本ロー ル等の混合機を用いて、調製することができる。ただし、加熱条件下で混合する場合 には、熱重合開始剤の分解開始温度以下で行うことが好ましレ、。 The curable resin composition used in the present invention comprises the above (A) ethylenically unsaturated group-containing fluoropolymer and the above (B) component, or, if necessary, the above (C) component, (D) component, It can be prepared by adding (E) an organic solvent and (F) an additive and mixing at room temperature or under heating conditions. Specifically, it can be prepared using a mixer such as a mixer, a kneader, a ball mill, or a triple roll. However, when mixing under heating conditions, it is preferable to carry out at a temperature lower than the decomposition start temperature of the thermal polymerization initiator.
[0088] 硬化性樹脂組成物の硬化条件についても特に制限されるものではないが、例えば 活性エネルギー線を用いた場合、露光量を 0. 01〜10j/cm2の範囲内の値とする のが好ましい。 [0088] There is no particular limitation on the curing conditions of the curable resin composition, for example, when using the active energy rays, to a value within the range of exposure amount of 0. 01~10j / cm 2 Is preferred.
この理由は、露光量が 0. 01j/cm2未満となると、硬化不良が生じる場合があるた めであり、一方、露光量が lOj/cm2を超えると、硬化時間が過度に長くなる場合が あるためである。 This is because when the exposure dose is less than 0.01 j / cm 2 , curing failure may occur. On the other hand, when the exposure dose exceeds lOj / cm 2 , the curing time may become excessively long. Because there is.
また、このような理由により、露光量を 0.:!〜 5j/cm2の範囲内の値とするのがより 好ましぐ 0. 3〜3j/cm2の範囲内の値とするのがより好ましい。 Moreover, these reasons, however, it falls is more preferred instrument 0. 3~3j / cm 2 to a value within the range of exposure amount of 0.:!~ 5j / cm 2 More preferred.
[0089] また、硬化性樹脂組成物を、加熱して硬化させる場合には、 30〜200°Cの範囲内 の温度で、 1〜: 180分間加熱するのが好ましい。このように加熱することにより、基材 等を損傷することなぐより効率的に耐擦傷性に優れた反射防止膜を得ることができ る。 [0089] When the curable resin composition is cured by heating, it is preferably heated at a temperature in the range of 30 to 200 ° C for 1 to 180 minutes. By heating in this way, an antireflection film having excellent scratch resistance can be obtained more efficiently without damaging the substrate and the like.
また、このような理由から、 50〜: 180°Cの範囲内の温度で、 2〜: 120分間加熱する のがより好ましく、 80〜: 150°Cの範囲内の温度で、 5〜60分間加熱するのがさらに好 ましい。
[0090] 3.反射防止膜 For this reason, it is more preferable to heat at a temperature in the range of 50 to 180 ° C for 2 to 120 minutes, and for a temperature in the range of 80 to 150 ° C for 5 to 60 minutes. Even more preferred is heating. [0090] 3. Antireflection film
基材上に、上記硬化性樹脂組成物の硬化膜からなる低屈折率層を含んで、本発 明の反射防止膜を作製できる。さらに、この反射防止膜は、低屈折率層の下に、高 屈折率層、中屈折率層、ハードコート層、帯電防止層等を含むことができる。 The antireflection film of the present invention can be produced by including a low refractive index layer comprising a cured film of the curable resin composition on a substrate. Further, the antireflection film can include a high refractive index layer, a medium refractive index layer, a hard coat layer, an antistatic layer, and the like below the low refractive index layer.
図 1に、力、かる反射防止膜 10を示す。図 1に示すように、基材 12の上に、帯電防止 層 14、ハードコート層 16及び低屈折率層 18が積層されている。 FIG. 1 shows the force and the antireflection coating 10. As shown in FIG. 1, an antistatic layer 14, a hard coat layer 16, and a low refractive index layer 18 are laminated on a substrate 12.
また、ハードコート層 16と低屈折率層 18の間に、さらに、高屈折率層(図示せず。 ) を設けてもよい。 Further, a high refractive index layer (not shown) may be further provided between the hard coat layer 16 and the low refractive index layer 18.
さらに、ハードコート層 16を設けずに、帯電防止層 14の上に、直接、低屈折率層 18 を形成してもよい。 Further, the low refractive index layer 18 may be formed directly on the antistatic layer 14 without providing the hard coat layer 16.
[0091] (1)低屈折率層 [0091] (1) Low refractive index layer
低屈折率層は、硬化性樹脂組成物を硬化して得られる硬化膜から構成される。硬 化性樹脂組成物の構成等については、上述の通りであるため、ここでの具体的な説 明は省略するものとし、以下、低屈折率層の屈折率及び厚さについて説明する。 The low refractive index layer is composed of a cured film obtained by curing the curable resin composition. Since the configuration and the like of the curable resin composition are as described above, a specific description thereof will be omitted, and the refractive index and thickness of the low refractive index layer will be described below.
[0092] 硬化性樹脂組成物を硬化して得られる硬化膜の屈折率 (Na— D線(589nm)の屈 折率、測定温度 25°C)、即ち、低屈折率膜の屈折率を 1. 45以下とすることが好まし レ、。この理由は、低屈折率膜の屈折率が 1. 45を超えると、高屈折率膜と組み合わせ た場合に、反射防止効果が著しく低下する場合があるためである。 [0092] The refractive index of the cured film obtained by curing the curable resin composition (the refractive index of Na-D line (589 nm), measuring temperature 25 ° C), that is, the refractive index of the low refractive index film is 1 45 or less is preferable. This is because when the refractive index of the low refractive index film exceeds 1.45, the antireflection effect may be significantly reduced when combined with a high refractive index film.
従って、低屈折率膜の屈折率を 1 · 44以下とするのがより好ましぐ 1. 43以下とす るのがさらに好ましい。 Therefore, it is more preferable that the refractive index of the low refractive index film is 1 · 44 or less.
尚、低屈折率膜を複数層設ける場合には、そのうちの少なくとも一層が上述した範 囲内の屈折率の値を有していればよぐ従って、その他の低屈折率膜は 1. 45を超え た値であってもよい。 When providing a plurality of low refractive index films, it is sufficient that at least one of them has a refractive index value within the above-mentioned range. Therefore, the other low refractive index films exceed 1.45. It may be a value.
[0093] また、低屈折率層を設ける場合、より優れた反射防止効果が得られることから、高屈 折率層との間の屈折率差を 0. 05以上の値とするのが好ましい。この理由は、低屈折 率層と、高屈折率層との間の屈折率差が 0. 05未満の値となると、これらの反射防止 膜層での相乗効果が得られず、却って反射防止効果が低下する場合があるためで ある。
従って、低屈折率層と、高屈折率層との間の屈折率差を 0.:!〜 0. 5の範囲内の値 とするのがより好ましぐ 0. 15-0. 5の範囲内の値とするのがさらに好ましい。 [0093] Further, when a low refractive index layer is provided, it is preferable to set the refractive index difference with respect to the high refractive index layer to a value of 0.05 or more because a better antireflection effect can be obtained. The reason for this is that if the difference in refractive index between the low refractive index layer and the high refractive index layer is less than 0.05, the synergistic effect of these antireflective film layers cannot be obtained, and instead the antireflective effect. This is because there is a case where the value decreases. Therefore, it is more preferable to set the difference in refractive index between the low refractive index layer and the high refractive index layer to a value within the range of 0.:! To 0.5. More preferably, the value is within the range.
[0094] 低屈折率層の厚さについても特に制限されるものではなレ、が、例えば、 50〜300n mであることが好ましい。この理由は、低屈折率層の厚さが 50nm未満となると、下地 としての高屈折率膜に対する密着力が低下する場合があるためであり、一方、厚さが 300nmを超えると、光干渉が生じて反射防止効果が低下する場合があるためである 従って、低屈折率層の厚さを 50〜250nmとするのがより好ましぐ 60〜200nmと するのがさらに好ましい。 [0094] The thickness of the low refractive index layer is not particularly limited, and is preferably 50 to 300 nm, for example. The reason for this is that when the thickness of the low refractive index layer is less than 50 nm, the adhesion to the high refractive index film as a base may decrease, whereas when the thickness exceeds 300 nm, optical interference does not occur. This is because the antireflection effect may be reduced, and therefore the thickness of the low refractive index layer is more preferably 50 to 250 nm, more preferably 60 to 200 nm.
尚、より高い反射防止性を得るために、低屈折率層を複数層設けて多層構造とす る場合には、その合計した厚さを 50〜300nmとすればよい。 In order to obtain higher antireflection properties, when a plurality of low refractive index layers are provided to form a multilayer structure, the total thickness may be 50 to 300 nm.
[0095] (2)高屈折率層 [0095] (2) High refractive index layer
高屈折率層を形成するための硬化性組成物としては、特に制限されるものでない 、被膜形成成分として、エポキシ系樹脂、フエノール系樹脂、メラミン系樹脂、アル キド系樹脂、シァネート系樹脂、アクリル系樹脂、ポリエステル系樹脂、ウレタン系榭 脂、シロキサン樹脂等の一種単独又は二種以上の組み合わせを含むことが好ましレヽ 。これらの樹脂であれば、高屈折率層として、強固な薄膜を形成することができ、結 果として、反射防止膜の耐擦傷性を著しく向上させることができるためである。 The curable composition for forming the high refractive index layer is not particularly limited. As a film forming component, an epoxy resin, a phenol resin, a melamine resin, an alkyd resin, a cyanate resin, an acrylic resin. It is preferable to include one kind alone or a combination of two or more kinds of resin, polyester resin, urethane resin, siloxane resin and the like. This is because these resins can form a strong thin film as the high refractive index layer, and as a result, the scratch resistance of the antireflection film can be remarkably improved.
し力 ながら、通常、これらの樹脂単独での屈折率は 1. 45〜: 1. 62であり、高い反 射防止性能を得るには十分で無い場合がある。そのため、高屈折率の無機粒子、例 えば金属酸化物粒子を配合することがより好ましレ、。金属酸化物粒子の具体例として は、アンチモンドープ酸化錫(ATO)粒子、錫ドープ酸化インジウム(IT〇)粒子、 Ζη Ο粒子、アンチモンドープ ZnO、 A1ドープ Ζη〇粒子、リンドープ酸化錫(ΡΤΟ)粒子 、 ZrO粒子、 TiO粒子、シリカ被覆 TiO粒子、 Al O /ZrO被覆 TiO粒子、 CeO However, the refractive index of these resins alone is usually 1.45 to: 1.62, which may not be sufficient to obtain high antireflection performance. Therefore, it is more preferable to blend high refractive index inorganic particles, for example, metal oxide particles. Specific examples of metal oxide particles include antimony-doped tin oxide (ATO) particles, tin-doped indium oxide (ITO) particles, Ζη Ο particles, antimony-doped ZnO, A1-doped ΖηΖ particles, and phosphorus-doped tin oxide (ΡΤΟ) particles. , ZrO particles, TiO particles, silica-coated TiO particles, Al 2 O 3 / ZrO-coated TiO particles, CeO
2 2 2 2 3 2 2 2 粒子等を挙げることができる。好ましくは、アンチモンドープ酸化錫 (AT〇)粒子、錫 ドープ酸化インジウム(IT〇)粒子、 A1ドープ ΖηΟ粒子、リンドープ酸化錫(ΡΤΟ)粒 子、 Al O /ZrO被覆 Ti〇粒子である。これらの金属酸化物粒子は、一種単独又は Examples include 2 2 2 2 3 2 2 2 particles. Antimony-doped tin oxide (AT) particles, tin-doped indium oxide (IT) particles, A1-doped ΖηΟ particles, phosphorus-doped tin oxide (ΡΤΟ) particles, and Al 2 O 3 / ZrO-coated Ti 0 particles are preferable. These metal oxide particles are one kind alone or

二種以上の組み合わせで使用することができる。
また、高屈折率層にハードコート層や帯電防止層の機能を持たせることもできる。ま た、硬化形態としては、熱硬化、紫外線硬化、電子線硬化できる硬化性組成物を用 いることができる力 より好適には生産性の良好な紫外線硬化性組成物が用いられる It can be used in a combination of two or more. Moreover, the function of a hard coat layer or an antistatic layer can be given to the high refractive index layer. Moreover, as a curing form, a force capable of using a curable composition capable of thermal curing, ultraviolet curing, and electron beam curing, an ultraviolet curable composition having good productivity is more preferably used.
[0096] 高屈折率層の厚さは特に制限されるものではなレ、が、例えば、 50-30, OOOnmで あることが好ましい。この理由は、高屈折率層の厚さが 50nm未満となると、低屈折率 層と組み合わせた場合に、反射防止効果ゃ基材に対する密着力が低下する場合が あるためであり、一方、厚さが 30, OOOnmを超えると、光干渉が生じて逆に反射防止 効果が低下する場合があるためである。 [0096] The thickness of the high refractive index layer is not particularly limited, but is preferably 50-30, OOOnm, for example. The reason for this is that when the thickness of the high refractive index layer is less than 50 nm, when combined with the low refractive index layer, the antireflection effect may decrease the adhesion to the substrate, while the thickness This is because if the thickness exceeds 30, OOOnm, optical interference may occur and the antireflection effect may be reduced.
従って、高屈折率層の厚さを 50〜: 1 , OOOnmとするの力より好ましく、 60〜500nm とするのがさらに好ましい。 Therefore, the thickness of the high refractive index layer is more preferably from 50 to 1: OOOnm, and more preferably from 60 to 500 nm.
また、より高い反射防止性を得るために、高屈折率層を複数層設けて多層構造とす る場合には、その合計した厚さを 50〜30, OOOnmとすれば良レ、。 In addition, in order to obtain higher antireflection properties, when a multilayer structure is formed by providing a plurality of high refractive index layers, it is good if the total thickness is 50-30, OOOnm.
尚、高屈折率層と基材との間にハードコート層を設ける場合には、高屈折率層の厚 さを 50〜300nmとすること力 Sでさる。 In addition, when providing a hard-coat layer between a high refractive index layer and a base material, the thickness S of a high refractive index layer shall be 50-300 nm, and force S is used.
[0097] (3)ハードコート層 [0097] (3) Hard coat layer
本発明の反射防止膜に用いるハードコート層の構成材料については特に制限され るものでない。このような材料としては、シロキサン樹脂、アクリル樹脂、メラミン樹脂、 エポキシ樹脂等の一種単独又は二種以上の組み合わせを挙げることができる。また 、耐擦傷性を増すために、シリカ粒子や、金属酸化物粒子を添加することもできるし、 硬化物層の変質を避けるために、酸化防止剤や光安定剤を添加することができる。 The constituent material of the hard coat layer used for the antireflection film of the present invention is not particularly limited. Examples of such a material include one kind of siloxane resin, acrylic resin, melamine resin, epoxy resin, or a combination of two or more kinds. In addition, silica particles and metal oxide particles can be added to increase scratch resistance, and an antioxidant and a light stabilizer can be added to avoid alteration of the cured product layer.
[0098] 酸化防止剤や光安定剤の具体例としては、例えば、スミライザ一 BHT、スミライザ 一 S、スミライザ一 BP_ 76、スミライザ一 MDP_ S、スミライザ一 GM、スミライザ一 B BM— S、スミライザ一 WX— R、スミライザ一 NW、スミライザ一 BP— 179、スミライザ 一 BP— 101、スミライザ一 GA_80、スミライザ一 TNP、スミライザ一 TPP_R、スミラ ィザー P— 16 (以上、住友化学 (株)製)、チヌビン 770、チヌビン 765、チヌビン 144 、チヌビン 622、チヌビン 111、チヌビン 123、チヌビン 292 (チバ'スペシャルティ'ケ ミカルズ (株)製)、ファンクリル FA_ 711M、 FA—712HM (日立化成工業(株)製)
等が挙げられる。 [0098] Specific examples of antioxidants and light stabilizers include, for example, Sumitizer 1 BHT, Summitizer 1 S, Summitizer 1 BP_76, Summitizer 1 MDP_S, Summitizer 1 GM, Summitizer 1 B BM-S, Summitizer 1 WX — R, Sumilyzer NW, Sumilyzer One BP—179, Sumilyzer One BP—101, Sumilyzer One GA_80, Sumilyzer One TNP, Sumilyzer One TPP_R, Sumilyzer P—16 (above, manufactured by Sumitomo Chemical Co., Ltd.), Tinuvin 770, Tinuvin 765, Tinuvin 144, Tinuvin 622, Tinuvin 111, Tinuvin 123, Tinuvin 292 (Ciba 'Specialty' Chemicals), Funkrill FA_711M, FA-712HM (Hitachi Chemical Industries, Ltd.) Etc.
[0099] ハードコート層の厚さについても特に制限されるものではなレ、が、:!〜 50 μ ΐηとする のが好ましぐ 1〜: ίθ μ ΐηとするのがより好ましレ、。この理由は、ハードコート層の厚さ 力 μ m未満となると、反射防止膜の基材に対する密着力を向上させることができな い場合があるためであり、一方、厚さが 50 x mを超えると、均一に形成するのが困難 となる場合があるためである。 [0099] The thickness of the hard coat layer is not particularly limited, but is preferably set to:! To 50 μΐη 1 to: more preferably set to ίθ μΐη, . The reason for this is that when the thickness of the hard coat layer is less than μm, the adhesion of the antireflection film to the substrate may not be improved, whereas the thickness exceeds 50 xm. This is because it may be difficult to form a uniform layer.
[0100] (4)導電層 [0100] (4) Conductive layer
