The present invention relates to the field of color filters and LCDs. More specifically, the invention relates to a colorant composition for making color filters comprising pyrimido[5,4- g]pteridine derivatives of formula (I) wherein A1, A2, A3, and A4 are each independently of the others -NR1R2, wherein R1 and R2 are each independently of the others hydrogen, CrC8alkyl, -CO-C1 -C8alkyl, -CO-Ce-Cuaryl, -COO-C1 -C8alkyl, -COO-Ce-CMaryl, -CONH-d-Cβalkyl or -CONH-Ce-CMaryl, Or A1, A2, A3, and A4 are each independently of the others -OH, -SH, hydrogen, CrC8alkyl, CrC8alkoxy, or C6-C14aryl or -O- C6-C14aryl each unsubstituted or mono- or poly-substituted by halogen, nitro, cyano, -OR10, -SR10, -NR10R11, -CONR10R11, -COOR10, -SO2R10, -SO2NR10R11, -SO3R10, -NR11COR10 or by -NR11COOR10, wherein R10 and R11 are each independently of the others hydrogen, CrC8alkyl, C5-C12cycloalkyl or C2-C8-alkenyl; and to their use for color filter production and to color filters comprising said pyrimido[5,4- g]pteridine derivatives of formula (I).
本发明涉及彩色滤光片和液晶显示器领域。更具体地说,本发明涉及一种用于制备彩色滤光片的柿崩[5,4-g]嘧啶衍生物的着色剂组合物,该柿崩[5,4-g]嘧啶衍生物的化学式为(I),其中A1、A2、A3和A4各自独立地是-NR1R2,其中R1和R2各自独立地是氢、CrC8烷基、-CO-C1-C8烷基、-CO-Ce-C芳基、-COO-C1-C8烷基、-COO-Ce-C芳基、-CONH-d-Cβ烷基或-CONH-Ce-C芳基;或者A1、A2、A3和A4各自独立地是-OH、-SH、氢、CrC8烷基、CrC8烷氧基或C6-C14芳基或-O-C6-C14芳基,每个未取代或单取代或多取代卤素、硝基、氰基、-OR10、-SR10、-NR10R11、-CONR10R11、-COOR10、-SO2R10、-SO2NR10R11、-SO3R10、-NR11COR10或-NR11COOR10,其中R10和R11各自独立地是氢、CrC8烷基、C5-C12环烷基或C2-C8烯基;以及它们用于彩色滤光片生产和包含该柿崩[5,4-g]嘧啶衍生物的化学式(I)的彩色滤光片。
