Description
本発明は、吸湿し難く樹脂溶解性に優れた印刷法によるパターン形成用溶剤組成物に関する。 The present invention relates to a solvent composition for pattern formation by a printing method that hardly absorbs moisture and has excellent resin solubility.
従来、配線基板やディスプレイなどの電子部品のパターン形成は、フォトリソグラフィと呼ばれる方法で形成されることが多かった。フォトリソグラフィは、ペースト組成物を基板に塗布し、微細パターンを露光して焼き付け、エッチングにて不要な部分を除去してパターン形成を行う方法である。しかし、一般に、エッチング廃液処理設備を必要とすることから装置自体が巨大となり、巨額の設備投資が必要であり、材料の使用効率も悪く、製造工程が多いため生産性が悪いことが問題であった。また、装置の容量に制限されるため大面積基板へのパターン形成は困難であった。 Conventionally, pattern formation of electronic components such as wiring boards and displays has often been formed by a method called photolithography. Photolithography is a method in which a paste composition is applied to a substrate, a fine pattern is exposed and baked, and unnecessary portions are removed by etching to form a pattern. However, in general, since an etching waste liquid treatment facility is required, the apparatus itself is huge, requiring a large amount of capital investment, poor material use efficiency, and many manufacturing processes, resulting in poor productivity. It was. In addition, since it is limited by the capacity of the apparatus, it is difficult to form a pattern on a large-area substrate.
そのため、近年、パターン形成方法としては、巨大な装置が不要で、材料の使用効率がよく、大面積基板への対応も容易である、インクジェット法、スクリーン印刷法、凸版印刷法、オフセット印刷法、グラビア印刷法、マイクロコンタクト印刷法、ナノインプリント法等の印刷法が注目されている。印刷法に用いられるペースト組成物の溶剤としては、ジエチレングリコールジメチルエーテルやジエチレングリコールジブチルエーテルなどのエチレングリコールエーテル系溶媒や、ジプロピレングリコールジメチルエーテル、ジプロピレングリコールジエチルエーテル、ジプロピレングリコールジプロピルエーテル、ジプロピレングリコールジブチルエーテルなどのプロピレングリコールエーテル系溶媒等が使用される例が多い。しかし、エチレングリコールエーテル系溶媒は生態毒性を有するため使用しづらいという問題があった(非特許文献1)。 Therefore, in recent years, as a pattern formation method, an inkjet method, a screen printing method, a letterpress printing method, an offset printing method, which does not require a huge apparatus, has good material use efficiency, and can easily cope with a large area substrate, Printing methods such as gravure printing, microcontact printing, and nanoimprinting have attracted attention. Solvents for the paste composition used in the printing method include ethylene glycol ether solvents such as diethylene glycol dimethyl ether and diethylene glycol dibutyl ether, dipropylene glycol dimethyl ether, dipropylene glycol diethyl ether, dipropylene glycol dipropyl ether, and dipropylene glycol dipropylene. In many cases, propylene glycol ether solvents such as butyl ether are used. However, ethylene glycol ether solvents have a problem that they are difficult to use because of their ecotoxicity (Non-patent Document 1).
一方、プロピレングリコールエーテル系溶媒について、特許文献1には、プロピレングリコールジエチルエーテルを有機エレクトロルミネッセンスデバイスを構成する素子パターン(以後、「有機ELデバイス素子」と称する場合がある)を印刷法により形成するペースト組成物に溶剤として使用することが記載されている。また、特許文献2には、プロピレングリコールジブチルエーテルを使用することが記載されている。更に、特許文献3にはプロピレングリコールエチルメチルエーテル、プロピレングリコールメチルプロピルエーテル、プロピレングリコールエチルプロピルエーテルを使用することが記載されている。 On the other hand, with respect to the propylene glycol ether solvent, in Patent Document 1, an element pattern (hereinafter sometimes referred to as “organic EL device element”) that forms propylene glycol diethyl ether in an organic electroluminescence device is formed by a printing method. The use as a solvent in a paste composition is described. Patent Document 2 describes the use of propylene glycol dibutyl ether. Further, Patent Document 3 describes the use of propylene glycol ethyl methyl ether, propylene glycol methyl propyl ether, propylene glycol ethyl propyl ether.
プロピレングリコールジアルキルエーテルは揮発性に優れているが、特にプロピレングリコールジメチルエーテルは親水性が高く吸湿し易いため、有機ELデバイス素子を形成するペースト組成物に溶剤として使用すると、前記有機ELデバイス素子を劣化させる恐れがあり、一方、プロピレングリコールジブチルエーテルは親油性が高く吸湿性は低いが、ペースト組成物に含有するエチルセルロースやアクリル樹脂などのバインダー樹脂の溶解性が低いため、印刷用溶剤又は溶剤組成物として使用することは困難であることが分かった。また、プロピレングリコールエチルメチルエーテル、プロピレングリコールメチルプロピルエーテル、及びプロピレングリコールエチルプロピルエーテルもまた、樹脂添加物の溶解性と吸湿性のバランスの点で不十分であるということが分かった。 Propylene glycol dialkyl ether is excellent in volatility, but especially propylene glycol dimethyl ether is highly hydrophilic and easy to absorb moisture. Therefore, when used as a solvent in a paste composition for forming an organic EL device element, the organic EL device element deteriorates. On the other hand, propylene glycol dibutyl ether has high lipophilicity and low hygroscopicity, but the solubility of binder resins such as ethyl cellulose and acrylic resin contained in the paste composition is low, so a printing solvent or solvent composition As found to be difficult to use. In addition, it has been found that propylene glycol ethyl methyl ether, propylene glycol methyl propyl ether, and propylene glycol ethyl propyl ether are also insufficient in terms of the balance between solubility and hygroscopicity of the resin additive.

The compound having a C 4-5 alkyl group is excellent in the balance of solubility and hygroscopicity of the resin additive, and the compound is used as a paste composition for pattern formation of an organic electroluminescent device that forms an organic electroluminescent device element. When added as a solvent, it has been found that an organic EL device element that can exhibit sufficient binder resin solubility to form an element pattern by a printing method and hardly deteriorates due to moisture absorption can be formed. The present invention has been completed based on these findings.

一般に、有機ELデバイスは一層〜多層からなる発光層が2つの電極(陽極、陰極)に挟まれた構造を有する。 In general, an organic EL device has a structure in which a light-emitting layer composed of one to multiple layers is sandwiched between two electrodes (anode and cathode).
有機ELデバイスは、例えば、下記工程を経て製造される。本発明に係るパターン形成方法によれば、高精度の有機ELデバイス素子を形成することができる。
1:ガラス等の基板上に陽極を形成する。
2:ガラス等の基板上の、陽極を形成した部分以外の部分に隔壁を形成する。
3:陽極上に、赤、緑、青、又は白色の発光層を印刷法により形成し、硬化させる。
4:発光層及び隔壁の上に陰極を形成する。
An organic EL device is manufactured through the following processes, for example. According to the pattern forming method of the present invention, a highly accurate organic EL device element can be formed.
1: An anode is formed on a substrate such as glass.
2: A partition wall is formed on a portion of the substrate such as glass other than the portion where the anode is formed.
3: A red, green, blue, or white light emitting layer is formed on the anode by a printing method and cured.
4: A cathode is formed on the light emitting layer and the partition.
本発明に係るパターン形成方法は印刷法を用いるため、基板に対して非接触の状態でパターンを形成することができ、大面積及び/又はフレキシブルな基板にも容易にパターン形成を行うことができる。そのため、特に、有機ELデバイス素子の製造において、微細な素子パターンを高精度に形成することができる。また、マスクの作成等の複雑な工程を経ることなく直接描写することが可能であり、微細加工技術を用いる必要がない。更に、常温常圧環境下で製造することができる。そのため、製造プロセスの大幅な簡素化、設備の簡素化、製造コストの低減化が可能である。 Since the pattern forming method according to the present invention uses a printing method, the pattern can be formed in a non-contact state with respect to the substrate, and the pattern can be easily formed even on a large area and / or a flexible substrate. . Therefore, in particular, in the production of organic EL device elements, a fine element pattern can be formed with high accuracy. Further, it is possible to directly depict the image without complicated processes such as mask creation, and it is not necessary to use a fine processing technique. Furthermore, it can be manufactured under a normal temperature and normal pressure environment. Therefore, it is possible to greatly simplify the manufacturing process, simplify equipment, and reduce manufacturing costs.
