That is, (1) Dyes are generally inferior in heat fastness, light fastness and the like as compared with pigments.

Description
上記のようなカラーフィルタの製造方法としては種々の方法が提案されている。中でも、色素を含有する感光性樹脂組成物を露光し、現像することによってパターニングする工程を所要の回数繰り返し行う、いわゆるカラーレジスト法は広く実用化されている。
(1)染料は、一般的に顔料に比べて熱堅牢性、光堅牢性等に劣る。
(2)染料のモル吸光係数が低い場合には、多量の染料を添加しなければならず、着色硬化性組成物中の重合性化合物やバインダー、光重合開始剤等の他の成分を相対的に減らさざるを得ない。その結果、硬化された硬化部の熱堅牢性、次層塗布時の耐溶剤性が不十分である。
(3)染料のモル吸光係数が高いものであっても、溶解性の悪い染料は液状調製物への溶解性向上又は液状調製物の安定性向上のために分子量を大きくする必要がある。その結果、多量(重量)の染料を添加しなければならず、着色硬化性組成物中の重合性化合物やバインダー、光重合開始剤等の他の成分を相対的に減らさざるを得ない。従って、硬化された硬化部の熱堅牢性、次層塗布時の耐溶剤性が不十分である。
また、上記課題(2)、(3)の課題を改善するために、キノフタロン色素のポリマー染料に関する検討がなされている(特許文献7)。しかしながら、近年のカラーフィルタにおけるパターンの高精細化の点で、提案されているポリマー染料では十分ではなくさらなる改良が求められていた。

また、少なくとも1つのエチレン性不飽和基を有する置換基と少なくとも1つのカルボキシル基とを有するキノフタロン色素は、例えば、特許文献7に記載されている例示化合物22及び39が挙げられる。
