Description

著色感光性樹脂組合物 Colored photosensitive resin composition

本發明係關於一種綠色之著色感光性樹脂組合物,尤其是關於一種含有C.I.顏料綠58、C.I.顏料黃185及C.I.顏料黃138作為著色劑(A)之著色感光性樹脂組合物。 The present invention relates to a green colored photosensitive resin composition, in particular to a colored photosensitive resin composition containing C.I. Pigment Green 58, C.I. Pigment Yellow 185 and C.I. Pigment Yellow 138 as colorants (A).

近年來,為了擴大顯示器可顯示之色彩再現區域而正在進行開發,作為其一環,亦要求彩色濾光片之顏色更濃。為了滿足該要求,可列舉提高彩色濾光片中之色料濃度之方法,但若色料濃度上升,則圖案形狀劣化等,作為著色感光性樹脂組合物之性能劣化,故而欠佳。又,為了具有目標顏色特性,必須以厚膜之方式製作彩色濾光片,但於應用於液晶顯示裝置之情形時,產生與鄰接像素之光之混色,因此厚膜化亦欠佳。 In recent years, in order to expand the displayable color reproduction area of the display, development is being carried out. As part of this, the color filter is also required to be denser. In order to meet this requirement, a method of increasing the color material concentration in the color filter can be cited. However, if the color material concentration increases, the pattern shape deteriorates, and the performance as a colored photosensitive resin composition deteriorates, which is not preferable. In addition, in order to have the target color characteristics, the color filter must be made by a thick film method. However, when applied to a liquid crystal display device, color mixing with the light of adjacent pixels occurs, so the thick film is not good.

於專利文獻1中,為了設計濃色之綠色彩色濾光片而記載有如下綠色感光性樹脂組合物,其包含:含有C.I.顏料綠58、C.I.顏料藍15:3及C.I.顏料黃150等之著色劑,樹脂,聚合性單體,光聚合起始劑及溶劑。 In Patent Document 1, in order to design a dense green color filter, the following green photosensitive resin composition is described, which includes a coloring containing CI Pigment Green 58, CI Pigment Blue 15:3, CI Pigment Yellow 150, etc. Agents, resins, polymerizable monomers, photopolymerization initiators and solvents.
