Definitions
- the present invention relates to a hydrophilic film having antifogging properties, antifouling properties, and antistatic properties, excellent in abrasion resistance and weather resistance, a polymerizable composition for obtaining the same, and a use thereof.
- Non-Patent Document 1 As a method for solving this fogging problem, an antifogging paint in which a reactive surfactant is added to an acrylic oligomer has been proposed, and a cured film obtained from this antifogging paint has improved hydrophilicity and water absorption.
- Non-Patent Document 1 Also, for example, as a method of solving the problem of dirt, self-cleaning that improves the hydrophilicity of the surface and efficiently removes dirt (hydrophobic substances etc.) adhering to the outer wall, etc. by floating or spraying water.
- An antifouling material having a property has attracted attention (Non-Patent Documents 2 and 3).
- the present inventors have proposed a monolayer film in which anionic hydrophilic groups are inclined (concentrated) on the surface as a proposal for completely overcoming the problems of “cloudiness” and “dirt” (Patent Document 1). .
- the hydrophilic film obtained by this invention is transparent and extremely hydrophilic, and has excellent antifogging properties, antifouling properties, antistatic properties, quick drying properties (fast drying speed of attached water), and chemical resistance, Moreover, it is hard and has excellent scratch resistance. However, according to the study by the present inventors, it has been found that the wear resistance and weather resistance are insufficient.
- a method of coating an inorganic compound is known as a method of improving weather resistance with excellent weather resistance.
- a silica compound by a sol-gel reaction is used as a hard coat of a spectacle lens (Non-patent Document 4).
- Silica coat is very hard due to its dense structure, and its wear resistance reaches the same level as glass, but on the other hand, there are problems such as being easily broken, not being dyed, and being easily adhered to dirt.
- Various proposals have been made for solving these problems. For example, as a method for imparting dyeability and toughness, a method of blending a melamine polyhydric alcohol condensate and a silane compound having an epoxy group into silica (Patent Document 2), a method of blending an epoxy compound and an aluminum complex into silica (patent) Document 3) and a method of blending an acrylic polymer having a hydroxyl group with silica (Patent Document 4) have been proposed.
- Patent Document 5 As a method for imparting antifogging properties by hydrophilization, a method of blending a styrene-based sulfonic acid polymer with silica (Patent Document 5) has been proposed.
- Patent Document 5 The proposal described in Patent Document 5 is a preferable proposal that tends to increase the hydrophilicity, but the polymer tends to be detached from the film, and the hydrophilicity tends to decrease due to water.

- An object of the present invention is to provide a hydrophilic film that has an excellent balance between hydrophilicity and wear resistance, has little decrease in hydrophilicity due to water, and has excellent weather resistance.

一般式(1')で表される炭素-炭素二重結合を有する重合性官能基及びスルホン酸基を有する化合物と、一般式(2')で表される炭素-炭素二重結合を有する重合性官能基及びエポキシ基を有する化合物と、所要により用いられる上記「第3の構成単位前駆化合物」を、共重合させる場合の反応温度は、主に重合開始剤の10時間半減期温度で設定されるが、凡そ室温~200℃の範囲、好ましくは30~120℃の範囲、さらに好ましくは40~100℃の範囲である。
こうして生成した本発明の重合体(i)は、通常、スルホン酸基を多数有する高分子量体であり、水にしか溶解しないような性質を有することも多い。従って、この場合反応溶剤として、水を大量に用いなければ、反応の進行とともに反応系外へ析出してくるため、反応終了後、濾過して乾燥するだけで目的の重合体が得られる。一方、スルホン酸基の数が少なく析出しにくい重合体の場合は、貧溶剤に入れて析出させるか、エバポレーター等で溶剤を留去した後、貧溶剤でスラッジングし、濾過して乾燥する方法が比較的に好ましい。

ここで、重合体(i)とシラン化合物(ii)との換算重量比は、重合体(i)の重量と、シラン化合物(ii)に対応するシリカまたはその類似体に換算した重量との比として求めることができる。ここで、「シラン化合物(ii)に対応するシリカまたはその類似体に換算した重量」は、例えば、一般式(3)の場合は、以下の計算式によって算出される。
R3~R6の総数であるR3+R4+mR5+mR6のうちで、w個だけR10で置換された場合(R10は、水素原子、炭素数1~4のアルキル基、ビニル基、またはフェニル基を表し、wは、0以上の数を表す。)、縮重合後の「シラン化合物(ii)に対応するシリカまたはその類似体に換算した重量」は、「シラン化合物(ii)に対応するシリカまたはその類似体」が以下の式(100)で表されるとして計算される。
重合体(i)のスルホン酸基は硬化膜に高い親水性を付与し、シラン化合物(ii)は縮合重合し架橋することによって強固な硬化膜を与えるとともに、無機物の特徴である優れた耐候性も付与する。重合体(i)のエポキシ基はこのシラン化合物(ii)のシラノール基と反応する(反応式を一般式(4)で掲載)ことにより、重合体(i)をシラン化合物(ii)のネットワークに組み込ませる効果を生む。
・ スルホン酸基を有する化合物とエポキシ基を有する化合物が反応しない
・ スルホン酸基を有する化合物がシラン化合物(ii)と反応しない
ことにより、ネットワーク化されにくく、ネットワークに欠陥も生成しやすいため、本発明の重合体(i)を使用した場合と比較して、硬度および靭性の低下により耐磨耗性が低下し易い。また、
・エポキシ基を有する化合物は、本発明の重合体(i)よりも比較的低分子で極性が低い傾向にある
ため、疎水性のエポキシ基を有する化合物が表面へ移動し易くなるため、高い親水性が得られにくくなる。
基材と反対方向にある外表面におけるスルホン酸基濃度をSaとし、基材に接する界面と外表面との中間地点におけるスルホン酸基濃度をDaとした場合、スルホン酸基を有する本発明の重合体(i)の傾斜度は、スルホン酸基の濃度比(Sa/Da)で表される。すなわち、スルホン酸基の濃度比(Sa/Da)が大きいことは、多くのスルホン酸基が硬化膜の外表面に集中していることを示している。このことは、スルホン酸基の濃度比(Sa/Da)が大きいほど硬化膜の親水性が高く、本発明の膜を親水性膜として用いる上でより有利であることを意味する。ここで、上記Daについて、「基材に接する界面と外表面との中間地点」は、通常、基材に接する界面に向かって、外表面からの深さが膜厚の1/2の地点(本明細書においては、この地点を「膜厚1/2の地点」とも呼ぶ。)である。なお、SaおよびDaの説明において、「スルホン酸基」および「スルホン酸基濃度」なる語句は、それぞれ、「-SO3M基」および「-SO3M基の濃度」を意味する。
本発明に係る組成物は、スルホン酸基により高親水化された重合体(i)、および、重合体(i)と反応するシラン化合物(ii)を必須成分として含む重合性組成物であり、通常、スルホン酸基により高親水化された重合体(i)、重合体(i)と反応するシラン化合物(ii)、触媒、硬化材、およびそれらを均一または分散化させる溶剤からなる。

(5)SP値: 溶解パラメーター σ=(E1)1/2 〔単位:(cal/cm3 )1/2〕
このようなSP値(溶解パラメーターσ)(cal/cm3)1/2 が9.4以上の溶剤を用いることにより、重合体(i)に由来する親水性のスルホン酸基と一定の相互作用を有するため、この混合物を基材に塗布して、その混合物から溶剤を除去する際に、塗布された混合物の外気に接する表面に溶剤と同伴して親水性のスルホン酸基を有する重合体(i)が移動して、その表面に親水性のスルホン酸基が濃縮されることになり、本発明で得られる硬化膜外表面に親水基のスルホン酸基が集中した傾斜構造が形成される。

溶解パラメーターが9.4以上同士の混合溶剤であっても、できるだけ溶解パラメーターの高い(高極性)の溶剤を用いた方が良い。さらに高沸点側の溶剤の溶解パラメーターσ(cal/cm3)1/2 が、低沸点側の溶剤よりも高い方が傾斜化され易く、好ましい。
2種以上の溶剤を含む混合溶剤の混合比は、溶解パラメーターが最も高い溶剤/それ以外の溶剤の重量比が、好ましくは99.9/0.1~1/99、より好ましくは99/1~10/90、さらに好ましくは98/2~30/70の範囲である。
但し、水との混合溶剤の場合、水以外の溶剤が水と分離するような低極性溶剤であったり、水の添加量が多かったり、水よりも蒸発速度が必要以上に速い(低沸点)溶剤を混合すると、溶剤乾燥工程において、塗布された本発明の組成物が水滴状になりやすく、レベリング性の低下等により透明で平滑な膜が得られなくなる場合がある。従って、水との混合溶剤を選択する場合は、先ず、水と馴染みやすい高極性の溶剤を用いることにより本発明の組成物が均一溶液または均一分散液になるようにすることが肝要であるが、それ以外に、平滑性で透明な硬化膜を得るには、水/水以外の溶剤の重量混合比が、80/20~1/99に範囲が比較的に好ましく、70/20~5/95の範囲がより好ましく、60/40~10/90の範囲であればさらに好ましい。
尚、本発明において、蒸発速度比Rは以下の簡易計算式(A)~(B)によって計算される。
(A) 蒸発速度=乾燥温度での飽和蒸気圧(mmHg)×√(分子量)
(B) 水に対する蒸発速度比R=水以外の溶剤の蒸発速度/水の蒸発速度
例えば、50℃における水の蒸発速度は92.6と計算され、50℃で溶剤乾燥を行う場合の代表的な溶剤の蒸発速度比Rは、およそ以下の通り計算される。例えば、
メタノール=4.3、
エタノール=2.4、
IPA(2-プロパノール)=1.8、
1-プロパノール=1.0、
1-ブタノール=0.4、
