【発明の属する技術分野】
本発明は、分子内にフッ素原子および不飽和結合を含有するアルコキシシラン誘導体を含有する硬化性組成物に関する。本発明の硬化性組成物は、たとえば光ラジカル開始剤を配合することにより活性エネルギー線硬化性組成物として用いることができる。当該硬化塗膜は低屈折率、耐汚染性、密着性、耐傷つき性、耐溶剤性等に優れた特性を示し、反射防止フィルム、防汚フィルムコーティング等の種々の用途に供することができる。
【0002】
【従来の技術】
従来から、プラスチック材料は、透明性に加えて、軽量、耐衝撃性および加工性などの諸特性に優れるため、家電業界、電気電子業界、自動車業界等様々な分野で多量に使用されている。しかしながら、プラスチック材料からなるフィルム、シート、成形品などにおいては、太陽光線や照明光の反射によるギラツキが生じたり、周囲の景観が反射投影されることにより、当該プラスチック材料が有する本来の透視性や光透過率が低下するという問題がある。
【0003】
そのため、従来からプラスチックの低反射化の検討が進められてきており、通常、当該プラスチック表面に反射防止膜を形成させて前記問題を解決している。反射防止膜の製造では、SiO2、ZrO2、Al2O3などの金属酸化物が利用され、真空蒸着やスパッタリングなどの方法によって単層あるいは複層の塗膜として形成されている。しかし、真空蒸着やスパッタリング法では、当該装置の機構やコスト面より、小型精密光学部品などに限定適用されるという制約があり、さらには連続製造には不適である。
【0004】
このような事情から、屈折率の低い含フッ素物質を、液状の組成物に調製し、当該組成物を基板の表面に塗布する方法が検討されている。例えば、基板の表面にフッ素化アルキルシランを塗布する方法(特許文献1参照)、特定構造を有するフッ素系重合体を塗布する方法(特許文献2参照)、紫外線硬化型の含フッ素コート剤を塗布する方法(特許文献3参照)などが提案されている。また、本願人は、既に紫外線硬化型のフッ素化アルコキシシラン誘導体や当該誘導体を配合してなる硬化性組成物を塗布する方法を出願した(特願2003−32362号)。

特開昭64−1527号公報
【特許文献2】
特開平6−115023号公報
【特許文献3】
特開平8−100136号公報
【0006】
【発明が解決しようとする課題】
しかしながら、前記従来技術のうち、フッ素系材料を塗布し熱硬化させてなる反射防止膜(特許文献1)は、硬化速度が遅く生産性に劣るという欠点があり、また紫外線硬化型フッ素系コート剤を用いて得られる反射防止膜層(特許文献3)は耐傷つき性が不十分であり、繰り返し擦った場合には当該層が剥がれるなどの問題を有している。更に、上記の含フッ素化合物(特許文献1、2、3)は、概して粘度が高いため、有機溶剤で希釈した塗工液として使用されるため、溶剤由来の環境的な問題も有している。また、フッ素化アルコキシシラン誘導体(特願2003−32362号)は、反応性希釈剤との相溶性が不十分で、混合できる樹脂が限定されていた。
【0007】
本発明は、有機溶剤を使用せずとも低粘度で塗工することができ、また相溶性が良いので各種の反応性希釈剤を使用することができ、しかも透明性、耐傷つき性、耐汚染性に優れ、低屈折率であって良好な反射防止効果を発揮できる硬化膜を連続的に形成しうる、硬化性樹脂組成物を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明者は前記課題を解決すべく、鋭意検討を重ねた結果、特定のアルコキシシラン誘導体を使用することにより、当該課題を悉く解決できるという知見を得、本発明を完成するに到った。
【0009】
すなわち、本発明は、加水分解性アルコキシシランおよび/またはその縮合物(a)と、フッ素含有アルコール(b)および重合性官能基を少なくとも1つ有するフッ素不含有アルコール(c)とを、脱アルコール反応させて得られるアルコキシシラン誘導体を含有することを特徴とする硬化性組成物;および当該硬化性組成物を硬化させて得られることを特徴とする硬化物に関する。
【0010】
【発明の実施の形態】
本発明に用いられる加水分解性アルコキシシランおよび/またはその縮合物(a)(以下、併せて(a)成分という)は、一般式(1):R1 mSi(OR2 4−m)(式中、R1は炭素数1〜8のアルキル基またはアリール基を表し、R2は水素原子または低級アルキル基を表し、mは0〜2の整数を表す。)で表される加水分解性アルコキシシランおよび/または当該加水分解性アルコキシシランの縮合物である。
【0011】
(a)成分のうち、加水分解性アルコキシシランとしては、例えばテトラメトキシシラン、テトラエトキシシラン、テトラプロポキシシラン、テトライソプロポキシシラン、テトラブトキシシラン等のテトラアルコキシシラン類、メチルトリメトキシシラン、メチルトリエトキシシラン、メチルトリプロポキシシラン、メチルトリブトキシシラン、エチルトリメトキシシラン、エチルトリエトキシシラン、n−プロピルトリメトキシシラン、n−プロピルトリエトキシシラン、イソプロピルトリメトキシシラン、イソプロピルトリエトキシシラン、ビニルトリメトキシシラン、ビニルトリエトキシシラン、3−グリシドキシプロピルトリメトキシシラン、3−グリシドキシプロピルトリエトキシシラン、3−メルカプトプロピルトリメトキシシラン、3−メルカプトプロピルトリエトキシシラン、フェニルトリメトキシシラン、フェニルトリエトキシシラン、3,4−エポキシシクロヘキシルエチルトリメトキシシラン、3,4−エポキシシクロヘキシルエチルトリメトキシシラン等のトリアルコキシシラン類、ジメチルジメトキシシラン、ジメチルジエトキシシラン、ジエチルジメトキシシラン、ジエチルジエトキシシラン等のジアルコキシシラン類等といったものがあげられる。
【0012】
(a)成分のうち、加水分解性アルコキシシランの縮合物とは、上記加水分解性アルコキシシランの1種または2種以上が縮合したものを表す。一般式(1)で表される加水分解性アルコキシシランの縮合物の縮合度は特に制限されないが、取り扱い性が良好なことから、加水分解性アルコキシシランの縮合物1分子あたりSi原子を平均2〜8個含有する縮合物が好ましい。なお、当該縮合物の構造は特に限定されず、直鎖構造、分岐構造のいずれでもよく、分岐鎖同士間に、または分岐鎖と主鎖との間に酸素原子を介する結合が存在してもよい。一般式(1)中、R2は水素原子または低級アルキル基ならばとくに制限されないが、アルコキシシリル基の加熱縮合反応において、低温で硬化させる場合や、硬化速度を速くしたい場合にはR2をメチル基とすることが好ましい。ここでいう低級アルキル基とは炭素数が1〜8のアルキル基を表す。これら(a)成分の中では、フッ素含有アルコール(b)および重合性官能基を少なくとも1つ有するアルコール(c)との反応性に優れる点で、テトラアルコキシシラン類および/またはトリアルコキシシラン類の縮合物が好ましい。
【0013】
フッ素含有アルコール(b)(以下、(b)成分という)としては特に限定されず、具体例として、1H,1H−トリフルオロエタノール、1H,1H−ペンタフルオロプロパノール、6−(パーフルオロエチル)ヘキサノール、1H,1H−ヘプタフルオロブタノール、2−(パーフルオロブチル)エタノール、3−(パーフルオロブチル)プロパノール、6−(パーフルオロブチル)ヘキサノール、2−パーフルオロプロポキシ−2,3,3,3−テトラフルオロプロパノール、2−(パーフルオロヘキシル)エタノール、3−(パーフルオロヘキシル)プロパノール、6−(パーフルオロヘキシル)ヘキサノール、2−(パーフルオロオクチル)エタノール、3−(パーフルオロオクチル)プロパノール、6−(パーフルオロオクチル)ヘキサノール、2−(パーフルオロデシル)エタノール等があげられる。これらはそれぞれを単独で、または組み合わせて使用できる。
【0014】
また、(b)成分は、不飽和結合を有するフッ素含有アルコールであってもよい。具体例として、3−パーフルオロブチル−2−ヒドロキシプロピル(メタ)アクリレート(なお、3−パーフルオロブチル−2−ヒドロキシプロピル(メタ)アクリレートとは3−パーフルオロブチル−2−ヒドロキシプロピルアクリレートおよび/または3−パーフルオロブチル−2−ヒドロキシプロピルメタクリレートをいい、以下(メタ)とは同様の意味である。)、3−パーフルオロヘキシル−2−ヒドロキシプロピル(メタ)アクリレート、3−(パーフルオロ−3−メチルブチル)−2ヒドロキシプロピル(メタ)アクリレート等があげられる。これらはそれぞれを単独で、または組み合わせて使用できる。
【0015】
重合性官能基を少なくとも1つ有するフッ素不含有アルコール(c)(以下、(c)成分という)としては特に限定されず、具体例として、2−ヒドロキシエチル(メタ)アクリレート、2−ヒドロキシプロピル(メタ)アクリレート、4−ヒドロキシブチル(メタ)アクリレートなどのヒドロキシアルキル(メタ)アクリレート類、前記ヒドロキシアルキル(メタ)アクリレート類などのε−カプロラクトン縮合物、ポリエチレングリコールモノ(メタ)アクリレート、ポリプロピレングリコールモノ(メタ)アクリレート、2−ヒドロキシフェノキシプロピル(メタ)アクリレート、ペンタエリスリトールトリ(メタ)アクリレート、ジペンタエリスリトールペンタ(メタ)アクリレートなどがあげられる。これらはそれぞれを単独で、または組み合わせて使用できる。
【0016】
(c)成分としては、エポキシ樹脂と(メタ)アクリル酸等との反応により得られるエポキシ(メタ)アクリレート、オリゴマー中に水酸基を有するように反応させて得られるポリエステル(メタ)アクリレートやポリウレタン(メタ)アクリレートなどもあげられる。これらはそれぞれを単独で、または組み合わせて使用できる。
【0017】
(a)成分、(b)成分および(c)成分の反応は、たとえば、前記各成分を仕込み、加熱して生成するアルコールを留去しながらエステル交換反応を行う。反応温度は50〜120℃程度、好ましくは90〜110℃であり、全反応時間は1〜15時間程度である。
【0018】
なお、脱アルコール反応を、120℃を超える温度で行うと、不飽和結合部が重合することにより、反応生成物が高粘度化またはゲル化する場合があるほか、反応系中で(a)成分の縮合に伴って、反応生成物の分子量が上がりすぎることによっても、高粘度化やゲル化の傾向が見られる場合がある。このような場合には、脱アルコール反応を反応途中で停止させるなどの方法により高粘度化、ゲル化を防止すればよい。
【0019】
また、上記のエステル交換反応に際しては、反応促進のために従来公知のエステル交換反応触媒を使用することができる。たとえば、リチウム、ナトリウム、カリウム、ルビジウム、セシウム、マグネシウム、カルシウム、バリウム、ストロンチウム、亜鉛、アルミニウム、チタン、コバルト、ゲルマニウム、錫、鉛、アンチモン、砒素、セリウム、硼素、カドミウム、マンガンのような金属や、これら酸化物、有機酸塩、ハロゲン化物、アルコキシド等があげられる。これらのなかでも、特に有機錫、有機酸錫が好ましく、具体的には、オクチル酸錫、ジブチル錫ジラウレート等が有効である。
【0020】
また、上記反応は溶剤中で行うこともできる。溶剤としては、(a)成分、(b)成分および(c)成分を溶解する有機溶剤であり、非プロトン性溶媒であれば特に制限はない。このような有機溶剤としては、例えば、ジメチルホルムアミド、ジメチルアセトアミド、テトラヒドロフラン、メチルエチルケトン、トルエン、キシレン等があげられる。
【0021】
こうして得られた、分子内にフッ素および重合性官能基を含有するアルコキシシラン誘導体(以下、本アルコキシシラン誘導体という)は、未反応の(a)成分を含有していてもよい。
【0022】
上記の脱アルコール反応を行う場合、(a)成分、(b)成分および(c)成分の使用割合は、通常、{(a)成分のアルコキシシリル基の当量}:{(b)成分の水酸基の当量}:{(c)成分の水酸基の当量}が10:(0.5〜4.5):(0.5〜4.5)の仕込み比率とするのが好ましく、10:(0.5〜2):(0.5〜2)とするのがより好ましい。(a)成分のアルコキシシリル基10当量に対し、(b)成分の水酸基の当量が0.5当量より少なくなる場合には低屈折率や防汚性などのフッ素の効果が得られず、さらに、(a)成分のアルコキシシリル基10当量に対し、(c)成分の水酸基の当量が0.5当量より少なくなる場合には活性エネルギー線照射の際に十分な硬化性が得られない。また、(a)成分のアルコキシシリル基10当量に対し、(b)および(c)の水酸基の当量の合計が5当量より多くなる場合には密着性向上等の特性が現れないためである。
【0023】
本アルコキシシラン誘導体は、分子中に不飽和結合及びアルコキシシリル基を有することより、活性エネルギー線、酸発生剤、塩基発生剤により架橋反応を行うことが可能となる。そのため、光ラジカル開始剤及び/または熱潜在性カチオン触媒、光ラジカル開始剤/(光酸発生剤または光塩基発生剤)を適宜に組み合わせて、本発明の硬化性組成物を調製することができる。
【0024】

【0027】
光塩基発生剤としては、何ら制限なく各種公知のものが使用できる。例えば、[(O−ニトロベンジル)オキシ]カルボニルシクロヘキシルアミン等のニトロベンジルカルバメート化合物類(ジャーナル・オブ・ジ・アメリカン・ケミカルソサイエティ(J.Am.Chem.Soc.),Vol.113,No.11,4305,1991参照)、N−[[1−(3,5−ジメトキシフェニル)−1−メチル−エトキシ]カルボニル]シクロヘキシルアミンN−[[1−(3,5−ジメトキシフェニル)−1−メチル−エトキシ]カルボニル]ピリジン等の光官能性ウレタン化合物類(ザ・ジャーナル・オブ・オーガニック・ケミストリー(J.Org.Chem.),Vol.55,No.23,5919,1990参照)等を使用することができる。
【0028】
前記光ラジカル開始剤の使用量は、硬化性樹脂組成物中で10重量%以下、好ましくは2〜5重量%とされる。なお、本発明の硬化性樹脂組成物を、電子線で硬化させる場合には不要とされる。また、熱潜在性カチオン触媒、光酸発生剤または光塩基発生剤の使用量は硬化性樹脂組成物中で10重量%以下、好ましくは2〜5重量%である。
【0029】
前記アルコキシシラン誘導体を含有する硬化性組成物には、さらに、一般的にゾル−ゲル法に用いられる加水分解性アルコキシシランおよび/またはその縮合物(d)(以下、併せて(d)成分という)を配合することができる。たとえば、一般式(2):R3 nSi(OR4)4−n(式中、nは0〜2の整数を示し、R3は炭素原子に直結した官能基を持っていてもよい低級アルキル基、アリール基、不飽和脂肪族残基を表し、同一でも異なっていてもよい。R4は水素原子または低級アルキル基を示す。)で表されるものがあげられる。(d)成分のうち、加水分解性アルコキシシランの具体例としては、テトラメトキシシラン、テトラエトキシシラン、テトラプロポキシシラン、テトライソプロポキシシラン、テトラブトキシシラン等のテトラアルコキシシラン類、メチルトリメトキシシラン、メチルトリエトキシシラン、メチルトリプロポキシシラン、メチルトリブトキシシラン、エチルトリメトキシシラン、エチルトリエトキシシラン、n−プロピルトリメトキシシラン、n−プロピルトリエトキシシラン、イソプロピルトリメトキシシラン、イソプロピルトリエトキシシラン、ビニルトリメトキシシラン、ビニルトリエトキシシラン、3−グリシドキシプロピルトリメトキシシラン、3−グリシドキシプロピルトリエトキシシラン、3−メルカプトプロピルトリメトキシシラン、3−メルカプトプロピルトリエトキシシラン、フェニルトリメトキシシラン、フェニルトリエトキシシラン、3,4−エポキシシクロヘキシルエチルトリメトキシシラン、3,4−エポキシシクロヘキシルエチルトリメトキシシラン等のトリアルコキシシラン類、ジメチルジメトキシシラン、ジメチルジエトキシシラン、ジエチルジメトキシシラン、ジエチルジエトキシシラン等のジアルコキシシラン類等といったものがあげられる。(d)成分のうち、加水分解性アルコキシシランの縮合物としては、特に限定はされないが、作業性の点から、一般式(2)で表される加水分解性アルコキシシランの縮合物1分子あたりSi原子を平均2〜8個有する直鎖状の縮合物が好ましい。
【0030】

BACKGROUND OF THE INVENTION
The present invention relates to an alkoxysilane derivative containing a fluorine atom and an unsaturated bond in the molecule.Curable composition containingAbout. Of the present inventionCurable compositionCan be used as an active energy ray-curable composition, for example, by blending a photo radical initiator. The cured coating film exhibits excellent properties such as low refractive index, stain resistance, adhesion, scratch resistance, and solvent resistance, and can be used for various applications such as antireflection film and antifouling film coating.
[0002]
[Prior art]
Conventionally, plastic materials are excellent in various properties such as light weight, impact resistance and processability in addition to transparency, and thus have been used in large quantities in various fields such as the home appliance industry, the electrical and electronics industry, and the automobile industry. However, in films, sheets, molded articles, etc. made of plastic materials, glare caused by reflection of sunlight or illumination light occurs, or the surrounding scenery is reflected and projected, so that the inherent transparency of the plastic material is There is a problem that the light transmittance decreases.
[0003]
For this reason, investigations have been made to reduce the reflection of plastics. Conventionally, an antireflection film is formed on the plastic surface to solve the above problem. In the manufacture of antireflection coatings, SiO2, ZrO2, Al2OThreeMetal oxides such as these are used, and are formed as a single-layer or multi-layer coating by a method such as vacuum deposition or sputtering. However, the vacuum deposition and sputtering methods are limited in that they are limited to small precision optical components due to the mechanism and cost of the apparatus, and are not suitable for continuous production.
[0004]
Under such circumstances, a method of preparing a fluorine-containing substance having a low refractive index into a liquid composition and applying the composition to the surface of a substrate has been studied. For example, a method of applying a fluorinated alkylsilane to the surface of a substrate (see Patent Document 1), a method of applying a fluorine-based polymer having a specific structure (see Patent Document 2), and applying an ultraviolet curable fluorine-containing coating agent And the like (see Patent Document 3) have been proposed. The present applicant has already filed a method for applying a UV-curable fluorinated alkoxysilane derivative or a curable composition containing the derivative (Japanese Patent Application No. 2003-32362).

[0006]
[Problems to be solved by the invention]
However, among the above prior arts, the antireflection film (Patent Document 1) obtained by applying a fluorine-based material and heat-curing has the disadvantage that the curing rate is slow and the productivity is inferior, and the ultraviolet-curing fluorine-based coating agent The antireflective film layer (Patent Document 3) obtained by using is insufficient in scratch resistance, and has a problem such that the layer peels off when repeatedly rubbed. Furthermore, since the above-mentioned fluorine-containing compounds (Patent Documents 1, 2, and 3) are generally high in viscosity, they are used as a coating liquid diluted with an organic solvent, and therefore have environmental problems due to the solvent. . Further, the fluorinated alkoxysilane derivative (Japanese Patent Application No. 2003-32362) has insufficient compatibility with the reactive diluent, and the resin that can be mixed is limited.
[0007]
The present invention can be applied with a low viscosity without using an organic solvent, and because it has good compatibility, various reactive diluents can be used, and transparency, scratch resistance, and contamination resistance can be used. An object of the present invention is to provide a curable resin composition that is capable of continuously forming a cured film that is excellent in properties and has a low refractive index and can exhibit a good antireflection effect.

In addition, when the dealcoholization reaction is performed at a temperature exceeding 120 ° C., the unsaturated bond part may be polymerized to cause the reaction product to become highly viscous or gelled. When the molecular weight of the reaction product is increased too much with the condensation of, a tendency to increase the viscosity or gel may be observed. In such a case, the viscosity increase or gelation may be prevented by a method such as stopping the dealcoholization reaction during the reaction.
