Colored curable composition, color filter and manufacturing method thereof
View Patent ↗The present invention provides a colored curable composition including a dye represented by the following formula (I), a color filter prepared by using the colored curable composition, and a method for manufacturing the color filter.
1. A colored curable composition comprising a binder, a radiation sensitive compound, a polymerizable monomer, and a dye represented by the following formula (I):
wherein R 1 represents a hydrogen atom or a substituent excluding perfluoroalkyl carbonylamino groups, sulfonamide groups, and sulfamoyl groups; R 2 to R 5 each independently represent a hydrogen atom or a substituent; R 6 and R 7 each independently represent an alkyl group, an alkenyl group, or an aryl group; Za and Zb each independently represent —N═ or —C(R 8 )═; R 8 represents a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group; and R 2 and R 3 , R 3 and R 6 , R 4 and R 5 , R 5 and R 7 , and/or R 6 and R 7 may be linked with each other to each independently form a 5-membered, 6-membered, or 7-membered ring.
2. The colored curable composition according to claim 1 , further comprising a cross-linking agent.
3. The colored curable composition according to claim 1 , further comprising a solvent.
4. The colored curable composition according to claim 1 , wherein the binder is alkali-soluble.
5. A color filter prepared by using the colored curable composition according to claim 1 .
6. A method for manufacturing a color filter comprising: applying the colored curable composition according to claim 1 on a substrate, exposing the colored curable composition to light through a mask, and developing the colored curable composition to form a pattern.
7. The colored curable composition according to claim 1 , wherein the dye is represented by the following formula (II):
wherein, R 101 has the same meaning as R 1 in formula (I); R 102 to R 104 have the same meanings as R 2 to R 4 , respectively, in formula (I); R 106 has the same meaning as R 6 in formula (I); R 9 to R 14 each independently represent a hydrogen atom or a substituent; and Zc and Zd have the same meanings as Za and Zb, respectively, in formula (I).
8. The colored curable composition according to claim 7 , further comprising a cross-linking agent.
9. The colored curable composition according to claim 7 , further comprising a solvent.
10. The colored curable composition according to claim 7 , wherein the binder is alkali-soluble.
11. A color filter prepared by using the colored curable composition according to claim 7 .
12. A method for manufacturing a color filter comprising: applying the colored curable composition according to claim 7 on a substrate, exposing the colored curable composition to light through a mask, and developing the colored curable composition to form a pattern.
13. The colored curable composition according to claim 7 , wherein the dye is represented by the following formula (III):
wherein R 9 to R 14 , R 101 to R 104 , and R 106 have the same meanings as in formula (II); and R 108 represents any one of a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, and a heterocyclic group.
14. The colored curable composition according to claim 13 , further comprising a cross-linking agent.
15. The colored curable composition according to claim 13 , further comprising a solvent.
16. The colored curable composition according to claim 13 , wherein the binder is alkali-soluble.
17. A color filter prepared by using the colored curable composition according to claim 13 .
18. A method for manufacturing a color filter comprising: applying the colored curable composition according to claim 13 on a substrate, exposing the colored curable composition to light through a mask, and developing the colored curable composition to form a pattern.
