The present invention relates to a novel salt forming compound and a colored curable resin composition represented by formula (AI), which can provide a color filter excellent in heat resistance. In the formulas, the ring Z 1 and the ring Z 2 independently represent a heterocyclic group which may have a substituent or an aromatic ring which may have a substituent, and the ring Z 1 and / or the ring Z 2 have an onium nitrogen atom . R a1 represents a saturated hydrocarbon group having 1 to 20 carbon atoms which may have a substituent. R 11 represents a hydrogen atom, a saturated hydrocarbon group having 1 to 20 carbon atoms, or an aralkyl group having 7 to 10 carbon atoms. X a1 - represents an anion containing at least one element selected from the group consisting of boron-containing anions, aluminum-containing anions, fluorine-containing anions and tungsten, molybdenum, silicon and phosphorus as essential elements. a1 represents an integer of 1 to 20; n is defined to be equal to the positive charge caused by the onionized nitrogen atom of ring Z < 1 > and / or ring Z < 2 >. |
