Description

活性エネルギー線硬化性組成物及びそれを用いたフィルムActive energy ray-curable composition and film using the same
　本発明は、フィルムの表面に塗工、硬化させることにより、フィルム表面に優れた帯電防止性を有するハードコート層を形成できる活性エネルギー線硬化性組成物及びそれを用いたフィルムに関する。 The present invention relates to an active energy ray-curable composition capable of forming a hard coat layer having excellent antistatic properties on a film surface by coating and curing the film surface, and a film using the same.
　各種樹脂フィルムは、液晶ディスプレイ（ＬＣＤ）、有機ＥＬディスプレイ（ＯＬＥＤ）、プラズマディスプレイ（ＰＤＰ）等のフラットパネルディスプレイ（ＦＰＤ）表面の傷付き防止用フィルム、自動車の内外装用加飾フィルム（シート）、窓向けの低反射フィルムや熱線カットフィルムなど各種用途に用いられている。しかしながら、樹脂フィルム表面は柔らかく耐擦傷性が低いため、これを補う目的で、ＵＶ硬化性組成物等からなるハードコート剤をフィルム表面に塗工、硬化させハードコート層をフィルム表面に設けることが一般的に行われている。ハードコート層を設ける工程を概略すると、ロール状に巻いてあるフィルム原反から塗工機へ送り出され、ハードコート剤が塗工され、紫外線照射により硬化してハードコート層を形成した後、再度ロール状に巻き取られる。 Various resin films include scratch prevention films on the surface of flat panel displays (FPD) such as liquid crystal displays (LCD), organic EL displays (OLED), plasma displays (PDP), decorative films (sheets) for interior and exterior of automobiles, It is used for various applications such as low reflection film for windows and heat ray cut film. However, since the resin film surface is soft and has low scratch resistance, a hard coat layer comprising a UV curable composition or the like may be applied to the film surface and cured to provide a hard coat layer on the film surface in order to compensate for this. Generally done. The outline of the process of providing a hard coat layer is sent out from a film roll wound in a roll shape to a coating machine, a hard coat agent is applied, cured by ultraviolet irradiation to form a hard coat layer, and again It is wound up into a roll.
　この巻き取り工程でフィルム同士の摩擦によりフィルム表面に静電気が発生するため、再加工時にフィルムをロールから繰り出した際にフィルム同士が張り付いてしまう問題や静電気によりフィルム表面に埃等が付着しやすくなる問題があった。また、このフィルムを液晶ディスプレイ等に用いた場合、発生した静電気によりディスプレイが誤動作する問題もあった。 In this winding process, static electricity is generated on the film surface due to the friction between the films. Therefore, when the film is unwound from the roll during reprocessing, the film surface sticks to the film surface, and dust tends to adhere to the film surface due to static electricity. There was a problem. Further, when this film is used for a liquid crystal display or the like, there is a problem that the display malfunctions due to generated static electricity.
　このフィルム表面での静電気の発生を抑制するため、ハードコート剤に帯電防止剤を配合する手法が一般的に行われている。例えば、ポリオキシエチレン鎖と４級アンモニウム塩とを有する化合物を帯電防止剤としてハードコート剤に配合する方法が提案されている（例えば、特許文献１参照。）。 In order to suppress the generation of static electricity on the film surface, a method of adding an antistatic agent to the hard coat agent is generally performed. For example, a method of blending a compound having a polyoxyethylene chain and a quaternary ammonium salt into a hard coat agent as an antistatic agent has been proposed (for example, see Patent Document 1).
　また、４級アンモニウム塩を有する重合性単量体を原料とした２種の共重合体を帯電防止剤としてハードコート剤に配合する方法が提案されている（例えば、特許文献２参照。）。 In addition, a method has been proposed in which two types of copolymers using a polymerizable monomer having a quaternary ammonium salt as a raw material are blended as an antistatic agent into a hard coat agent (for example, see Patent Document 2).
　しかしながら、これらの帯電防止剤を配合したハードコート剤は、帯電防止性能が十分ではなかった。そこで、より優れた帯電防止性を有するハードコート層を形成できる活性エネルギー線硬化性組成物が求められていた。 However, the hard coat agent containing these antistatic agents does not have sufficient antistatic performance. Therefore, there has been a demand for an active energy ray-curable composition that can form a hard coat layer having better antistatic properties.
