Description

感光性樹脂組成物Photosensitive resin composition
 本発明は、感光性樹脂組成物及びそれから得られる硬化膜に関する。
 より詳細には、高い撥水性と撥油性を硬化膜表面に有する画像を形成可能な感光性樹脂組成物及びその硬化膜、並びに該硬化膜を用いた各種材料に関する。この感光性樹脂組成物は、特に液晶ディスプレイやELディスプレイにおける層間絶縁膜、インクジェット方式に対応した遮光材料や隔壁材料として用いるのに好適である。
The present invention relates to a photosensitive resin composition and a cured film obtained therefrom.
More specifically, the present invention relates to a photosensitive resin composition capable of forming an image having high water repellency and oil repellency on the surface of the cured film, a cured film thereof, and various materials using the cured film. This photosensitive resin composition is particularly suitable for use as an interlayer insulating film in a liquid crystal display or an EL display, a light shielding material corresponding to an inkjet method, or a partition material.
薄膜トランジスタ(TFT)型液晶表示素子、有機EL(electroluminescent)素子等のディスプレイ素子の作製工程においてインクジェットを用いたフルカラー表示基板作製技術も近年活発に検討されている。たとえば液晶表示素子におけるカラーフィルタ作製に関しては、従来の印刷法、電着法、染色法または顔料分散法に対して、あらかじめパターニングされた画素を規定する区画(以下バンクという)を、光を遮断する感光性樹脂層で形成し、このバンクに囲まれた領域にインク滴を滴下するカラーフィルタおよびその製造方法(特許文献1)などが提案されている。また有機EL表示素子においてもあらかじめバンクを作製し、同様に発光層となるインクを滴下し、有機EL表示素子を作製する方法(特許文献2)が提案されている。
 しかしインクジェット法でバンクに囲まれた領域にインク滴を滴下する場合、バンクを超えて隣の画素にインク滴が溢れる事態を防ぐため、基板には親インク性(親水性、親油性)を持たせ、バンク表面には撥水性と撥油性を持たせる必要がある。
In recent years, a full color display substrate manufacturing technique using an ink jet in a manufacturing process of a display element such as a thin film transistor (TFT) type liquid crystal display element or an organic EL (electroluminescent) element has been actively studied. For example, with respect to the production of a color filter in a liquid crystal display element, light is blocked from a section (hereinafter referred to as a bank) that defines pixels that have been patterned in advance, compared to a conventional printing method, electrodeposition method, dyeing method, or pigment dispersion method. A color filter that is formed of a photosensitive resin layer and drops ink droplets in a region surrounded by the bank, a manufacturing method thereof (Patent Document 1), and the like have been proposed. Also, a method has been proposed (Patent Document 2) in which an organic EL display element is manufactured by preparing a bank in advance and dropping an ink serving as a light emitting layer in the same manner.
However, when ink droplets are dropped on the area surrounded by the bank by the inkjet method, the substrate has ink-philicity (hydrophilicity, oleophilicity) to prevent the ink droplet from overflowing to the adjacent pixels beyond the bank. The bank surface must be water and oil repellent.
 上記の目的を達成するため、酸素ガスプラズマ処理及びフッ素ガスプラズマ処理などの連続的プラズマ処理やUVオゾン処理により、基板に親水性を持たせ、且つバンクには撥水性を持たせることができると提案されている(特許文献3)。また、感光性有機薄膜にフッ素系界面活性剤やフッ素系ポリマーを配合した提案もなされている(特許文献4)が、相溶性や添加量など、感光性のみならず塗膜性も含めて考慮すべき点が多いだけでなく、基板の親水処理の際のUVオゾン処理で表面の撥水性が低下するため実用的ではなかった。 In order to achieve the above object, the substrate can be made hydrophilic and the bank can be made water repellent by continuous plasma treatment such as oxygen gas plasma treatment and fluorine gas plasma treatment or UV ozone treatment. It has been proposed (Patent Document 3). In addition, a proposal has been made that a fluorine-based surfactant or a fluorine-based polymer is blended with a photosensitive organic thin film (Patent Document 4), but consideration is given not only to photosensitivity but also to coating properties, such as compatibility. Not only is there much to be done, but also the UV ozone treatment during the hydrophilic treatment of the substrate reduces the water repellency of the surface, which is not practical.
 一方、従来、撥液バンクとして、ネガ型のものとしては特開2015-172742号公報(特許文献5)がある。また、ポジ型のものとしては特開2012-220860号公報(特許文献6)がある。 On the other hand, as a conventional liquid repellent bank, there is a negative type of Japanese Unexamined Patent Application Publication No. 2015-172742 (Patent Document 5). Moreover, as a positive type, there is JP 2012-220860 A (Patent Document 6).

 本発明は、上記の事情に鑑みなされたものであって、その解決しようとする課題は、液晶表示素子、有機EL表示素子等に使用され、UVオゾン処理をした後であっても硬化膜表面に高い撥水性と高い撥油性を有し、プラズマ処理やUVオゾン処理をせずとも基板に高い親液性を有する硬化膜の画像を形成することにある。特に、インクジェットを用いた基板作製において、バンクを超えて隣の画素にインク滴が溢れる事態を防ぐことができる硬化膜の画像を形成することにある。 The present invention has been made in view of the above circumstances, and the problem to be solved is used for liquid crystal display elements, organic EL display elements and the like, and even after UV ozone treatment, the surface of the cured film It is to form an image of a cured film having high water repellency and high oil repellency and high lyophilicity on a substrate without plasma treatment or UV ozone treatment. In particular, it is to form an image of a cured film that can prevent a situation where an ink droplet overflows to an adjacent pixel beyond a bank in manufacturing a substrate using inkjet.
 本発明者らは、上記目的を達成するために鋭意検討した結果、フッ素原子を有する有機基と熱架橋性基を有する有機基とを有するポリシロキサンを含む組成物から硬化膜を形成することにより、UVオゾン処理をした後であっても膜表面に撥液性を、プラズマ処理やUVオゾン処理をせずとも基板に高い親液性を効率的に付与できることを見出し、本発明を完成させた。 As a result of intensive investigations to achieve the above object, the present inventors have formed a cured film from a composition containing polysiloxane having an organic group having a fluorine atom and an organic group having a thermally crosslinkable group. The present inventors have found that even after UV ozone treatment, liquid repellency can be efficiently applied to the film surface, and high lyophilicity can be efficiently imparted to the substrate without plasma treatment or UV ozone treatment. .
