Description
本発明は、活性水素基含有含フッ素高分岐ポリマーと、イソシアネート基を有するラジカル重合性モノマーとを反応させることで得られる重合性含フッ素高分岐ポリマー、該重合性含フッ素高分岐ポリマーを添加した硬化性組成物、及び該硬化性組成物から得られるハードコートフィルムに関する。
In the present invention, a polymerizable fluorine-containing highly branched polymer obtained by reacting an active hydrogen group-containing fluorine-containing highly branched polymer with a radical polymerizable monomer having an isocyanate group, and the polymerizable fluorine-containing highly branched polymer are added. The present invention relates to a curable composition and a hard coat film obtained from the curable composition.
ポリマー(高分子)材料は、近年、多分野でますます利用されている。それに伴い、それぞれの分野に応じて、マトリクスとしてのポリマーの性状とともに、その表面や界面の特性が重要となっている。例えば、表面エネルギーの低いフッ素系化合物を表面改質剤として用いることにより、撥水撥油性、防汚性、非粘着性、剥離性、離型性、滑り性、耐磨耗性、反射防止特性、耐薬品性などの表面・界面制御に関する特性の向上が期待され、種々提案されている。
Polymer (polymer) materials are increasingly used in many fields in recent years. Along with this, the characteristics of the surface and interface of the polymer as a matrix, as well as the properties of the polymer, have become important for each field. For example, by using a fluorine compound with low surface energy as a surface modifier, water and oil repellency, antifouling properties, non-adhesiveness, peelability, release properties, slipperiness, wear resistance, antireflection properties Various improvements relating to surface / interface control such as chemical resistance are expected and various proposals have been made.
LCD(液晶表示装置)、PDP(プラズマディスプレイ)、タッチパネルなどの各種ディスプレイの表面には、傷付き防止のためのハードコート層を具備する各種プラスチックフィルムが使用されている。しかし、ハードコート層は指紋痕や汚れが付着しやすく、付着した指紋痕や汚れが簡単に除去できなかった。そのため、ディスプレイの画像の視認性が著しく損なわれたり、ディスプレイの美観が損なわれたりするという問題があった。特にタッチパネル表面は、直に人が手で触れるものであるため、とりわけ指紋痕が付着しにくく、かつ付着した場合には除去しやすいことが強く望まれている。
Various plastic films having a hard coat layer for preventing scratches are used on the surfaces of various displays such as LCD (liquid crystal display), PDP (plasma display), and touch panel. However, fingerprint marks and dirt are easily attached to the hard coat layer, and the attached fingerprint marks and dirt cannot be easily removed. For this reason, there has been a problem that the visibility of the image on the display is remarkably impaired or the aesthetic appearance of the display is impaired. In particular, since the surface of the touch panel is directly touched by a human hand, it is strongly desired that fingerprint marks are particularly difficult to adhere to and easy to remove when attached.
このようなハードコート層を有する反射防止フィルムにおいて、ハードコート層の表面を平坦化(レベリング、即ちなめらかにする)し、かつ防汚性を付与する目的で、フッ素化合物(フッ素系表面調整剤)をハードコート層形成用塗布液に添加してハードコート層を形成する方法が提案されている。フッ素化合物(フッ素系表面調整剤)は、層表面の指紋付着性及び指紋拭き取り性等の防汚性を向上させる機能を有する。しかし多くの場合、コーティングし成膜された塗膜表面には、防汚性を付与するために添加されたフッ素化合物が多量に存在するが、フッ素化合物は撥水・撥油性を有する一方、フッ素を含まない有機化合物に対して一般的に馴染みにくい性質を有するため、塗膜本来の性能に影響を及ぼすことも多い。
In such an antireflection film having a hard coat layer, a fluorine compound (fluorine-based surface conditioner) is used for the purpose of flattening (leveling, ie smoothing) the surface of the hard coat layer and imparting antifouling properties. There has been proposed a method of forming a hard coat layer by adding to a coating liquid for forming a hard coat layer. The fluorine compound (fluorine-based surface conditioner) has a function of improving antifouling properties such as fingerprint adhesion and fingerprint wiping properties on the layer surface. However, in many cases, the coating film surface that has been coated and formed contains a large amount of fluorine compound added to impart antifouling properties. However, while fluorine compounds have water and oil repellency, In general, it has properties that are difficult to adapt to organic compounds that do not contain, and therefore often affects the original performance of the coating film.
上述のハードコート層形成用塗布液としては、具体的には、フルオロアルキル基及び水酸基を有する含フッ素直鎖状ポリマーと、イソシアネート基含有(メタ)アクリルモノマーとを反応させて得られる重合型フッ素系界面活性剤を添加した、表面機能性の劣化が少ないハードコート層形成用塗布液が開示されている(特許文献1)。
一方、ポリマーの表面改質方法の一つとして、線状ポリマーからなるマトリクスポリマーに分岐ポリマーを添加し、該分岐ポリマーを該マトリクスポリマー表面に濃縮させる方法が知られている(特許文献2)。 As the above-mentioned coating liquid for forming a hard coat layer, specifically, a polymerization type fluorine obtained by reacting a fluorine-containing linear polymer having a fluoroalkyl group and a hydroxyl group with an isocyanate group-containing (meth) acryl monomer. A coating liquid for forming a hard coat layer, to which a surface-active agent is added and which causes little deterioration in surface functionality, is disclosed (Patent Document 1).
On the other hand, as one surface modification method of a polymer, there is known a method in which a branched polymer is added to a matrix polymer composed of a linear polymer, and the branched polymer is concentrated on the surface of the matrix polymer (Patent Document 2).

上述の通り、フッ素化合物(フッ素系表面調整剤)をハードコート層形成用塗布液に添加してハードコート層の表面を改質する方法は種々提案されているが、そのほとんどがレベリング性に起因する干渉色ムラに課題があり、より干渉色ムラのないハードコート層が望まれていた。
すなわち、ハードコート層を形成する材料への分散性が良好であり、得られるハードコート層の防汚性に優れ、その表面特性の劣化が少なく、しかも高いレベリング性で干渉色ムラを発生しない表面改質剤、及びそれを含むハードコート層を形成するための硬化性組成物が求められていた。 As described above, various methods for modifying the surface of the hard coat layer by adding a fluorine compound (fluorine-based surface conditioner) to the coating solution for forming the hard coat layer have been proposed, but most of them are due to leveling properties. There is a problem with the interference color unevenness, and a hard coat layer without interference color unevenness has been desired.
That is, a surface that has good dispersibility in the material forming the hard coat layer, excellent antifouling properties of the resulting hard coat layer, little deterioration of the surface characteristics, and high leveling properties that do not cause interference color unevenness There has been a demand for a curable composition for forming a modifier and a hard coat layer containing the same.

As a result of intensive studies to solve the above-mentioned problems, the present inventors have introduced a highly polymerizable fluorine-containing polymer obtained by introducing a fluoroalkyl group into a highly branched polymer side chain and introducing a radically polymerizable site. By employing a branched polymer as a surface modifier for the hard coat layer, the surface modifier is excellent in dispersibility in the curable composition for forming the hard coat layer, and the hard coat obtained The present inventors have found that the layer has excellent antifouling properties and can achieve high leveling properties regardless of the leveling agent, thereby completing the present invention.

本発明の重合性含フッ素高分岐ポリマーは、積極的に枝分かれ構造を導入しているため、線状高分子と比較して分子間の絡み合いが少なく、微粒子的挙動を示し、有機溶媒に対する溶解性及び樹脂に対する分散性が高い。このため本発明の重合性含フッ素高分岐ポリマーを、ハードコート形成用組成物等に配合し、ハードコート層を形成する際、微粒子状の該高分岐ポリマーは界面(ハードコート層表面)に容易に移動して、樹脂表面に防汚性等の活性を付与しやすい。
また、本発明の重合性含フッ素高分岐ポリマーは、そのポリマー側鎖にラジカル重合性の部位を有することから、活性エネルギー線硬化性モノマーとの混合・分散性が高く、該高分岐ポリマーの凝集が抑制され、硬化時の膜厚ムラに起因する干渉色ムラを抑制し、レベリング性が向上する。
従って、本発明の重合性含フッ素高分岐ポリマーをハードコート層形成用組成物に添加することで、干渉色ムラのない表面改質されたハードコート層を得ることができる。 Since the polymerizable fluorine-containing highly branched polymer of the present invention has positively introduced a branched structure, it has less entanglement between molecules than a linear polymer, exhibits fine particle behavior, and is soluble in organic solvents. And dispersibility with respect to resin is high. For this reason, when the polymerizable fluorine-containing highly branched polymer of the present invention is blended in a hard coat forming composition or the like to form a hard coat layer, the finely branched highly branched polymer is easy on the interface (hard coat layer surface). It is easy to give activity, such as antifouling property, to the resin surface.
In addition, since the polymerizable fluorine-containing highly branched polymer of the present invention has a radically polymerizable site in the polymer side chain, the mixing and dispersibility with the active energy ray-curable monomer is high, and the aggregation of the highly branched polymer is high. Is suppressed, interference color unevenness due to film thickness unevenness during curing is suppressed, and leveling properties are improved.
Therefore, by adding the polymerizable fluorine-containing highly branched polymer of the present invention to the composition for forming a hard coat layer, a surface-modified hard coat layer free from interference color unevenness can be obtained.
