本發明之一個實施方式係關於著色感光性樹脂組合物，該著色感光性樹脂組合物所包含之溶劑中含有丙二醇單甲醚乙酸酯及下述化學式1表示之化合物。 [化學式1]在該化學式1中，R1
分別獨立地為氫原子、甲基、甲氧基或乙氧基，R2

至C8
之伸烷基。溶劑
本發明涉及之著色感光性樹脂組合物之特徵在於，包含溶劑(a-1)，該溶劑(a-1)含有丙二醇單甲醚乙酸酯及該化學式1表示之化合物。 當該溶劑(a-1)包含丙二醇單甲醚乙酸酯及該化學式1表示之化合物時，包含其之著色感光性樹脂組合物之儲存穩定性得以提高，能夠抑制異物產生及著色劑析出。而且，該著色劑之分散性提高，能夠適當地調整黏度。由於在該著色劑分散時易於微粒化，因此提高了包含含有其之著色感光性樹脂組合物之固化物之濾色器的對比度。 具體地，該化學式1表示之化合物可為選自由二乙氧基甲烷(Diethoxymethane)、二丙氧基甲烷(dipropoxymethane)、二丁氧基甲烷(dibutoxymethane)、雙(2-甲氧基乙氧基)甲烷(bis(2-methoxyethoxy)methane)及3,3'-(亞甲基雙(氧亞甲基))雙庚烷(3,3'-Methylenebis(oxymethylene))bisheptane) 組成之群中之一種以上。更具體地，選自由二丁氧基甲烷及雙(2-甲氧基乙氧基)甲烷組成之群中之一種以上。當溶劑(a-1)包含選自由該二丁氧基甲烷及雙(2-甲氧基乙氧基)甲烷組成之群中之一種以上時，能夠防止塗佈後採用真空的溶劑蒸發過程中由於溶劑的急劇蒸發而產生的坑點(crater)不良。 對該丙二醇單甲醚乙酸酯及該化學式1之化合物之混合比雖然無特別限制，具體地，可以100 :1至100 : 50之重量比進行混合；更具體地可以100 :1至100 : 30之重量比進行混合。當該混合比在上述範圍之內時，能夠提高包含其之著色感光性樹脂組合物之儲存穩定性及該著色感光性樹脂組合物所包含的著色劑的分散性。 根據本發明之一實施形態，本發明之著色感光性樹脂組合物亦可包含上述溶劑(a-1)之外的溶劑(a-2)。該著色感光性樹脂組合物亦可包含之溶劑(a-2)只要能夠溶解該著色感光性樹脂組合物亦可包含之其他成分，則無特別限制，具體可例舉：醚類、芳族烴類、酮類、醇類、酯類等。此等化合物可單獨使用，亦可多於兩者混合使用。 該溶劑(a-2)具體可例舉：乙二醇單甲醚、乙二醇單乙醚、乙二醇單丙醚、乙二醇醇單丁醚等之乙二醇單烷基醚類、雙乙二醇二甲醚、雙乙二醇二乙醚、雙乙二醇雙丙醚、雙乙二醇雙丁醚等之雙乙二醇二甲醚類、甲基纖維素乙酸酯、乙基纖維素乙酸酯等之乙二醇烷基醚乙酸酯類、丙二醇單乙醚乙酸酯、丙二醇單丙醚乙酸酯、甲氧基丁基乙酸酯、甲氧基戊基乙酸酯等之烯烴基乙二醇烷基醚乙酸酯類、苯、甲苯、二甲苯、均三甲苯等之芳族烴類、甲基乙基酮、丙酮、甲基戊基酮、甲基異丁基酮、環己酮等之酮類、乙醇、丙醇、丁醇、正己醇、環己醇、乙二醇、丙三醇等之醇類、3-乙氧基丙酸乙酯、3-甲氧基丙酸甲酯等之酯類、γ-丁內酯等之環狀酯類等。 此外，該溶劑(a-2)具體在塗佈性及乾燥性方面可使用沸點為100℃至200℃之有機溶劑，更具體地可使用丙二醇單乙醚乙酸酯、環己酮、乳酸乙酯、乳酸丁酯、3-乙氧基丙酸乙酯、3-甲氧基丙酸甲酯等。 相對於該著色感光性樹脂組合物總量100重量%，本發明之著色感光性樹脂組合物中可包含60至90重量%、具體為65至87重量%、更具體為70至85重量%之溶劑。當該溶劑之含量滿足上述範圍時，以輥塗機、勻膠機、狹縫旋轉塗佈機、狹縫塗佈機(或者亦稱為Die coater)、噴墨等塗敷裝置進行塗覆時，能夠有望獲得良好的塗佈性。當該溶劑之含量低於上述範圍時，隨著塗佈性之些許變差，由包含其之著色感光性樹脂組合物製成之濾色器上會出現污點。當超出上述範圍時，用包含其之著色感光性樹脂組合物進行塗覆時難以達到所要求的塗膜厚度，導致使用其製備之濾色器高色彩再現比較困難。 根據本發明之一種實施形態，本發明之著色感光性樹脂組合物亦包含選自由著色劑、鹼性可溶性樹脂、光聚合性化合物及光聚合引發劑組成之群中之一種以上。著色劑
