工程(1)は、本発明の樹脂組成物を基板(下地基板)に塗布する工程である。基板としては、ガラス、金属、プラスチック等が挙げられ、基板上にカラーフィルタ、絶縁膜、導電膜及び/又は駆動回路等が形成されていてもよい。基板上への塗布は、スピンコーター、スリット&スピンコーター、スリットコーター、インクジェット、ロールコータ、ディップコーター等の塗布装置を用いて行うことが好ましい。
Step (1) is a step of applying the resin composition of the present invention to a substrate (underlying substrate). Examples of the substrate include glass, metal, plastic, and the like, and a color filter, an insulating film, a conductive film, a driving circuit, and the like may be formed on the substrate. Coating onto the substrate is preferably carried out using a coating device such as a spin coater, a slit & spin coater, a slit coater, an inkjet, a roll coater, and a dip coater.
工程(1)においては、基板の外周部に樹脂組成物の盛り上がりが発生したり、基板の裏面に樹脂組成物が回り込んだりすることがある。盛り上がりを形成したり、基板の裏面に回り込んだりした樹脂組成物は、後段の工程において、設備を汚したり、露光や加熱の精度を低下させる原因となる。本発明の樹脂組成物は、溶剤溶解性に優れるので、不要な樹脂組成物をきれいに除去することができ、不要な樹脂組成物に起因する問題を抑制することができる。また溶剤溶解性に難がある樹脂組成物は設備の配管閉塞の原因になることがあり好ましくない。
In step (1), the resin composition may swell around the outer periphery of the substrate, or the resin composition may wrap around the back surface of the substrate. The resin composition that forms a bulge or runs around to the back surface of the substrate causes contamination of equipment and lowers the accuracy of exposure and heating in subsequent steps. Since the resin composition of the present invention has excellent solvent solubility, it is possible to cleanly remove unnecessary resin compositions and to suppress problems caused by unnecessary resin compositions. Moreover, a resin composition having poor solubility in a solvent is not preferred because it may cause clogging of pipes in equipment.
工程(2)は、塗布後の樹脂組成物を減圧乾燥及び/又は加熱乾燥させて、組成物層を形成する工程である。該工程を行うことにより、樹脂組成物中の溶剤等の揮発成分を除去する。減圧乾燥は、50~150Paの圧力の下で、20~25℃の温度範囲で行うことが好ましい。減圧乾燥の前又は後に、加熱乾燥(プリベーク)を行ってもよい。加熱乾燥は、通常、オーブン、ホットプレート等の加熱装置を用いて行う。加熱乾燥の温度は、好ましくは30~120℃、より好ましくは50~110℃である。また加熱時間は、好ましくは10秒間~60分間、より好ましくは30秒間~30分間である。
Step (2) is a step of drying the applied resin composition under reduced pressure and/or by heating to form a composition layer. By performing this step, volatile components such as solvents in the resin composition are removed. Vacuum drying is preferably carried out under a pressure of 50-150 Pa in a temperature range of 20-25°C. Heat drying (pre-baking) may be performed before or after vacuum drying. Heat drying is usually performed using a heating device such as an oven or a hot plate. The temperature for drying by heating is preferably 30 to 120°C, more preferably 50 to 110°C. The heating time is preferably 10 seconds to 60 minutes, more preferably 30 seconds to 30 minutes.
工程(3)は、組成物層を加熱する工程(ポストベーク)である。加熱は、通常、オーブン、ホットプレート等の加熱装置を用いて行う。加熱温度は、好ましくは130~270℃、より好ましくは150~260℃、さらに好ましくは200~250℃である。加熱温度が、200~250℃であると、膜中に不要な溶剤が残存することを防ぐことができる。加熱時間は、好ましくは1~120分間、より好ましくは10~60分間である。
Step (3) is a step of heating the composition layer (post-baking). Heating is usually performed using a heating device such as an oven or a hot plate. The heating temperature is preferably 130 to 270°C, more preferably 150 to 260°C, still more preferably 200 to 250°C. A heating temperature of 200 to 250° C. can prevent unnecessary solvent from remaining in the film. The heating time is preferably 1 to 120 minutes, more preferably 10 to 60 minutes.
工程(2a)は、工程(2)により形成された組成物層を、フォトマスクを介して露光する工程である。該フォトマスクは、組成物層の除去したい部分に対応して、遮光部が形成されたものを用いる。遮光部の形状は、特に限定されず、目的とする用途に応じて選択できる。露光に用いられる光源としては、250~450nmの波長の光を発生する光源が好ましい。例えば、350nm未満の光を、この波長域をカットするフィルタを用いてカットしたり、436nm付近、408nm付近、365nm付近の光を、これらの波長域を取り出すバンドパスフィルタを用いて選択的に取り出したりしてもよい。光源としては、水銀灯、発光ダイオード、メタルハライドランプ、ハロゲンランプ等が挙げられる。
露光面全体に均一に平行光線を照射することや、フォトマスクと組成物層との正確な位置合わせを行うことができるため、マスクアライナ、ステッパ等の露光装置を用いることが好ましい。 Step (2a) is a step of exposing the composition layer formed in step (2) through a photomask. The photomask used has a light-shielding portion corresponding to a portion of the composition layer to be removed. The shape of the light shielding portion is not particularly limited, and can be selected according to the intended use. The light source used for exposure is preferably a light source that emits light with a wavelength of 250 to 450 nm. For example, light of less than 350 nm is cut using a filter that cuts this wavelength range, or light near 436 nm, 408 nm, and 365 nm is selectively extracted using a bandpass filter that extracts these wavelength ranges. You can Light sources include mercury lamps, light emitting diodes, metal halide lamps, halogen lamps, and the like.
It is preferable to use an exposure apparatus such as a mask aligner, a stepper, etc., because it is possible to uniformly irradiate the entire exposure surface with parallel rays and to perform accurate alignment between the photomask and the composition layer.

It is preferable to use an exposure apparatus such as a mask aligner, a stepper, etc., because it is possible to uniformly irradiate the entire exposure surface with parallel rays and to perform accurate alignment between the photomask and the composition layer.
工程(2b)は、露光後の組成物層を現像する工程である。露光後の組成物層を現像液に接触させて現像することにより、組成物層の未露光部が現像液に溶解して除去されて、基板上にパターンを有する組成物層が形成される。現像液としては、水酸化カリウム、炭酸水素ナトリウム、炭酸ナトリウム、水酸化テトラメチルアンモニウム等のアルカリ性化合物の水溶液が好ましい。これらのアルカリ性化合物の水溶液中の濃度は、好ましくは0.01~10質量%、より好ましくは0.03~5質量%である。さらに、現像液は、界面活性剤を含んでいてもよい。 現像方法は、パドル法、ディッピング法及びスプレー法等のいずれでもよい。さらに現像時に基板を任意の角度に傾けてもよい。現像後は、水洗することが好ましい。
The step (2b) is a step of developing the composition layer after exposure. By contacting the exposed composition layer with a developer for development, the unexposed portion of the composition layer is dissolved in the developer and removed, thereby forming a patterned composition layer on the substrate. The developer is preferably an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, tetramethylammonium hydroxide. The concentration of these alkaline compounds in the aqueous solution is preferably 0.01-10 mass %, more preferably 0.03-5 mass %. Furthermore, the developer may contain a surfactant. The development method may be any of the puddle method, dipping method, spray method, and the like. Furthermore, the substrate may be tilted at any angle during development. It is preferable to wash with water after development.
工程(3a)は、現像後の組成物層を加熱する工程である。前記工程(3)と同様にして加熱を行うことにより、パターンを有する組成物層が硬化して、パターンを有する膜が基板上に形成される。
The step (3a) is a step of heating the composition layer after development. By heating in the same manner as in step (3), the patterned composition layer is cured to form a patterned film on the substrate.
このようにして得られる膜は、例えば、液晶表示装置、有機EL表示装置や電子ペーパーに用いられるカラーフィルタ基板として有用である。これにより、高品質の膜を備えた表示装置を製造することが可能となる。着色パターンの凹凸形状を表面に有するカラーフィルタ基板においても、本発明の樹脂組成物によりオーバーコート層を形成することができる。
The film thus obtained is useful, for example, as a color filter substrate used in liquid crystal display devices, organic EL display devices, and electronic paper. This makes it possible to manufacture display devices with high-quality films. The resin composition of the present invention can be used to form an overcoat layer even on a color filter substrate having a colored pattern on its surface.
オーバーコート層の膜厚(被塗布面が凹凸形状を有する場合は凸部の表面からの膜厚)は、好ましくは0.5μm以上5μm以下、より好ましくは0.5μm以上3μm以下である。本発明の樹脂組成物は、被塗布面が凹凸形状を有する場合、例えば、凹部の幅が1~500μm、凹部の表面から凸部の表面までの高さが0.1~20μmである凹凸形状を有する下地基板に用いることができる。
The film thickness of the overcoat layer (the film thickness from the surface of the projections when the surface to be coated has an uneven shape) is preferably 0.5 μm or more and 5 μm or less, more preferably 0.5 μm or more and 3 μm or less. When the surface to be coated of the resin composition of the present invention has an uneven shape, for example, the width of the concave portion is 1 to 500 μm, and the height from the surface of the concave portion to the surface of the convex portion is 0.1 to 20 μm. can be used for a base substrate having
