ガラス基板上に各重合性組成物をスピンコート(ポストベイク後の色度座標(x、y)=(0.135,0.098)になるように)し、ホットプレートを用いて、90℃で120秒間プリベイクを行った後、23℃で60秒間冷却した。その後、超高圧水銀ランプを用いて150mJ/cm2で露光後、クリーンオーブンを用いて230℃で20分ポストベイクを行い、評価サンプルを作成した。得られたサンプルの380~780nmにおける透過率から、JIS Z8701に準拠してY値を求めた。Y値が高いほど輝度が高く可視光領域において高い透過率を有することを意味し、有用である。Y値が9.5以上のものは、カラーフィルタとして使用でき、Y値が11.0以上の物は特に好ましく使用でき、Y値が9.5未満のものはカラーフィルタとして適さない。
