Abstract

The present invention provides a dye compound excellent in both chroma and light fastness, an ink, and a resist composition for a color filter.
The present invention provides an ink and a resist composition for a color filter, in which each of the ink and the resist composition contains a pyridone azo compound having a specific structure.

First claim

The invention claimed is:

1. A dye compound represented by the general formula (1):

wherein in the general formula (1),
R 1 and R 2 each independently represent an alkyl group, an aryl group, or an amino group; R 3 and R 4 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a carboxylate group, or a carboxamide group,
L represents a linear alkylene group having 1 to 12 carbon atoms, a branched alkylene group having 1 to 12 carbon atoms, or a phenylene group,
m and n each independently represent an integer of 0 to 4,
i) when L represents a linear alkylene group having 1 to 12 carbon atoms or a branched alkylene group having 1 to 12 carbon atoms, A 1 , A 2 , B 1 in the case that m represents an integer of 1 to 4, and B 2 in the case that n represents an integer of 1 to 4, each independently represent a carboxamide group,
ii) when L represents a phenylene group, A 1 , A 2 , B 1 in the case that m represents an integer of 1 to 4, and B 2 in the case that n represents an integer of 1 to 4, each independently represent a sulfonate group, a carboxamide group, or a sulfonamide group; and
at least one of A 1 and A 2 represents a di(2-ethylhexyl)carboxamide group.

2. The dye compound according to claim 1 , wherein in the general formula (1), moieties on both sides of the group represented by L have the same structure.

3. The dye compound according to claim 1 , wherein in the general formula (1), L represents a linear alkylene group having 1 to 12 carbon atoms or a branched alkylene group having 1 to 12 carbon atoms.

4. The dye compound according to claim 3 , wherein in the general formula (1), L represents an ethylene group.

5. An ink comprising:
the dye compound according to claim 1 ,
wherein the dye compound is dissolved or dispersed in a medium.

6. A resist composition for a color filter, comprising:
the dye compound according to claim 1 ;
a binder resin; and
a medium,
wherein the dye compound and the binder resin are dissolved or dispersed in the medium.
