また、式(dx-1a)において、Tが基(Ib)である場合、RF12は、炭素原子数3~15のペルフルオロアルキレン基、または炭素原子数3~15のエーテル性酸素原子を含むペルフルオロアルキレン基が好ましく、炭素原子数4~6のペルフルオロアルキレン基が特に好ましい。
RF12がエーテル性酸素原子を含むペルフルオロアルキル基である場合、Q11およびQ12としては、-(CH2)i1-、-CH2O(CH2)i2-、-SO2NR1-(CH2)i3-、または-(C=O)-NR1-(CH2)i4-で表される基が好ましい。この場合においても、Q11およびQ12としては、-(CH2)i1-がより好ましい。i1は2~4の整数がさらに好ましく、i1は2が特に好ましい。
ケイ素原子に4個の加水分解性基が結合した加水分解性シラン化合物(s2)を混合物(M)に含ませることで、撥インク剤(D)を含むネガ型感光性樹脂組成物を硬化してなる硬化膜において、撥インク剤(D)が上面移行した後の造膜性を高められる。すなわち、加水分解性シラン化合物(s2)中の加水分解性基の数が多いことから、上面移行した後に、撥インク剤(D)同士が良好に縮合し、上面全体に薄い膜を形成して撥インク層となると考えられる。
また、混合物(M)に加水分解性シラン化合物(s2)を含ませることで、部分加水分解縮合物とした場合には、撥インク剤(D)は炭化水素系の溶媒に溶解しやすくなる。
加水分解性シラン化合物(s2)は、1種を単独で用いても、2種以上を併用してもよい。
SiX2 4 …(dx-2)

上記混合物(M)において、加水分解性シラン化合物(s2)を用いる場合、例えば、感光性樹脂組成物を硬化してなる隔壁において、その上面の端部に盛り上がりが形成される場合がある。この盛り上がりは、走査型電子顕微鏡(SEM)等によって観察されるレベルの微小なものであるが、他の部分よりもFおよび/またはSiの含有量が多いことが確認された。
加水分解性基の数の多い加水分解性シラン化合物(s2)によって生成されるシラノール基同士の反応により、撥インク剤(D)の造膜性は増加するが、その高い反応性のために、上記盛り上がりが起こると考えられる。そこで、加水分解性シラン化合物(s2)の一部を、加水分解性基の数の少ない加水分解性シラン化合物(s3)に置き換えることで、シラノール基同士の反応が抑えられ、上記盛り上がりの発生が抑えられると考えられる。
加水分解性シラン化合物(s3)は、1種を単独で用いても、2種以上を併用してもよい。
加水分解性基としては、加水分解性シラン化合物(s1)の加水分解性基と同様のものを用いることができる。

(E-Q6)s-Si(RH6)tX6 (4-s-t) …(dx-4)
式(dx-4)中、Eはカチオン重合性基、例えば、オキセタニル基、エポキシ基、グリシドキシ基または3,4-エポキシシクロヘキシル基である。

撥インク剤(D)の一例として、化合物(dx-1a)を必須成分として含み、化合物(dx-2)および化合物(dx-4)を任意成分として含み、化合物(dx-1a)中の基Tがフッ素原子である混合物(M)が挙げられる。各化合物の含有量は上記のとおりが好ましい。
式(II)中、n1~n3は構成単位の合計モル量に対する各構成単位のモル分率を示す。n1>0、n2≧0、n3≧0、n1+n2+n3=1である。その他の各符号は、上述のとおりである。ただし、Tはフッ素原子である。
式(II)で表される平均組成式は、撥インク剤(D1)において、加水分解性基またはシラノール基の全てがシロキサン結合となったと仮定した場合の化学式である。
また、式(II)において、化合物(dx-1a)、(dx-2)、および(dx-3)にそれぞれ由来する単位は、ランダムに配列していると推測される。

n2は、n3=0の場合は0~0.98が好ましく、n3>0の場合は0.05~0.6が好ましい。

なお、上記各成分の好ましいモル比は、化合物(dx-1a)中のTが基(Ib)である場合も同様である。
数平均分子量(Mn)が上記下限値以上であると、感光性樹脂組成物を用いて隔壁を形成する際に、撥インク剤(D)が上面移行しやすい。上記上限値未満であると、撥インク剤(D)の溶媒への溶解性が良好になる。
撥インク剤(D)の数平均分子量(Mn)は、製造条件により調節できる。
上記反応には、通常用いられる塩酸、硫酸、硝酸、リン酸等の無機酸、あるいは、酢酸、シュウ酸、マレイン酸等の有機酸を触媒として用いることが好ましい。また、必要に応じて、水酸化ナトリウム、水酸化テトラメチルアンモニウム(TMAH)等のアルカリ触媒を用いてもよい。
上記反応には公知の溶媒を用いることができる。
上記反応で得られる撥インク剤(D)は、溶媒とともに、溶液の性状で感光性樹脂組成物に配合してもよい。
撥インク剤(D)の含有量は、アルカリ可溶性樹脂(A)の100質量部に対して0.01~20質量部が好ましく、0.1~10質量部がより好ましく、0.2~3質量部が特に好ましい。撥インク剤(D)の含有量を上記範囲とすることで、上面に充分な撥インク性を有する隔壁が得られる。
本発明のネガ型感光性樹脂組成物は、溶媒(E)を含有することで粘度が低減され、ネガ型感光性樹脂組成物の基材表面への塗布がしやすくなる。その結果、均一な膜厚のネガ型感光性樹脂組成物の塗膜が形成できる。
溶媒(E)としては公知の溶媒が用いられる。溶媒(E)は、1種を単独で用いても、2種以上を併用してもよい。
本発明におけるネガ型感光性樹脂組成物は、さらに、必要に応じて、着色剤、熱架橋剤、高分子分散剤、分散助剤、シランカップリング剤、微粒子、硬化促進剤、増粘剤、可塑剤、消泡剤、レベリング剤、ハジキ防止剤等の他の添加剤を1種または2種以上含有してもよい。
また、本発明のネガ型感光性樹脂組成物を用いれば、低露光量で、上面に良好な撥インク性を有する撥インク層を有する隔壁の製造が可能である。さらに、該撥インク層が、紫外線/オゾン洗浄処理等の親インク化処理を経ても、優れた撥インク性を持続できる隔壁の製造が可能である。
本発明により製造できる隔壁は、上面に充分な撥インク性を有する撥インク層を有し、微細で精度の高いパターンの形成が可能である。
本発明によれば、隔壁で仕切られた開口部に、インクが均一に塗布され精度よく形成されたドットを有する光学素子、具体的には、有機EL素子、量子ドットディスプレイ、TFTアレイ、薄膜太陽電池等が提供できる。
本発明の隔壁は、基板表面をドット形成用の複数の区画に仕切る形に形成された、上記のネガ型感光性樹脂組成物の硬化物からなる。該隔壁は、例えば、基板等の基材の表面に、本発明のネガ型感光性樹脂組成物を塗布し、必要に応じて、乾燥して溶媒等を除去した後、ドット形成用の区画となる部分にマスキングを施し、露光した後、必要に応じて、加熱し、現像することで得られる。
この乾燥過程において、撥インク剤(D)は乾燥膜の上層部に移行する。なお、ネガ型感光性樹脂組成物が、溶媒(E)を含有しない場合であっても、塗膜内で撥インク剤(D)の上面移行は同様に達成される。
照射する光としては、波長100~600nmの光が好ましく、300~500nmの光がより好ましく、i線(365nm)、h線(405nm)またはg線(436nm)を含む光が特に好ましい。また、必要に応じて330nm以下の光をカットしてもよい。
単位面積当たりの露光時間は、通常1~60秒間程度、好ましくは1~30秒である。
このようにして、撥インク剤(D)は、撥インク層4Aおよび下部層4Bを含む隔壁に充分に定着しているため、現像時に開口部にマイグレートすることがほとんどない。
加熱により、隔壁4の硬化はより強固なものとなり、撥インク剤(D)は、撥インク層4A内により強固に定着する。
隔壁の高さは0.05~50μmであることが好ましく、0.2~10μmであることが特に好ましい。
本発明の実施形態の光学素子としては、基板表面に複数のドットと隣接するドット間に位置する本発明の隔壁とを有する、有機EL素子、量子ドットディスプレイ、TFTアレイまたは薄膜太陽電池が挙げられる。上記の有機EL素子、量子ドットディスプレイ、TFTアレイ、または薄膜太陽電池において、ドットはIJ法により形成されることが好ましい。
なお、本発明の実施形態の光学素子である有機EL素子等におけるドットの形成方法は、以下に限定されない。
図2Aおよび図2Bは、図1Dに示す基板1上に形成された隔壁4を用いて有機EL素子を製造する方法を模式的に示すものである。ここで、基板1上の隔壁4は、開口部5が、製造しようとする有機EL素子のドットのパターンに一致するように形成されたものである。

次にドット内に半導体溶液をIJ法によって塗布し、溶液を乾燥させることによって半導体層を形成する。この半導体溶液としては、有機半導体溶液、無機の塗布型酸化物半導体溶液等も用いることができる。ソース電極およびドレイン電極は、この半導体層を形成した後に、インクジェット法などの手法を用いて形成されてもよい。
