Provided are a curing composition containing a colorant which is excellent in light resistance, heat resistance, clearness and development, a color filter containing the composition, and a method for preparing the color filter. The curing composition contains a colorant which comprises a compound represented by the formula 1 or its tautomer, wherein a ring A1, a ring A2, a ring A3 and a ring A4 are independently a benzene ring or a benzene ring containing a nitrogen atom as a ring member (wherein at least one of them is a benzene ring containing a nitrogen atom as a ring member); R1 and R2 are independently H or a substituted or unsubstituted alkyl group (wherein both R1 and R2 cannot be H simultaneously); m is an integer of 1-8; and n is an integer of 1-4. |
