<p>The invention provides a coloring composition applied in a color filter, a color filter and a colored liquid crystal display element. The coloring composition applied in a color filter has excellent chroma features, development and storing stability. The coloring composition comprises A a coloring agent including pigments, B a segmented copolymer and C a cross-linking agent. The B segmented copolymer comprises a repeating unit 1 illustrated in formula 1, a repeating unit 2 illustrated in formula 2 and a repeating unit 3 having an acidic group, and further comprises A segment having the repeating unit 1, and B segment having the repeating unit 2 and repeating unit 3. In formula 1, R1 represents a hydrogen atom or methyl, Z represents -N+R2R3R4Y-, -NR5R6. or a nitrogen-containing heterocyclic radical with a substituent, and X1 represents divalent connecting groups. In formula 2, R7 represents alkylidene with a carbon atom number ranging from 2 to 4, R8 represents alkyl with carbon atom number ranging from 1 to 6, R9 represents a hydrogen atom or methyl, and n represents an integer ranging from 1 to 150. R2 to R4, R5 and R6 mutually independently represent hydrogen atoms or alkyl with substituents. Y- represents a counterbalance anion.</p> |
