Abstract

The present invention provides a compound represented by formula (I) or formula (II) capable of reducing the color difference before and after post-baking. [In the formula (I), R 1 represents a C2-C20 unsaturated hydrocarbon group optionally having a substituent; R 2 represents a hydrogen atom, a C1-C20 hydrocarbon group optionally having a substituent, or a single bond connecting Z 2 and R 1 ; and Z 1 and Z 2 each independently represent a single bond or an oxygen atom, and in the formula (II), R 3 represents a C2-C20 unsaturated hydrocarbon group optionally having a substituent; and Z 3 represents a single bond or an oxygen atom].

Claims (18)

1 . A compound represented by formula (I) or formula (II):

wherein in the formula (I),

R 1 represents an aliphatic unsaturated hydrocarbon group having 2 to 20 carbon atoms and optionally having a substituent;

R 2 represents a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms and optionally having a substituent, or a single bond connecting Z 2 and R 1 ;

Z 1 and Z 2 each independently represent a single bond or an oxygen atom;

X 1 to X 4 each independently represent —R 4 , —OR 4 , —SR 4 , a halogen atom, a nitro group, or a sulfamoyl group optionally having a substituent;

R 4 represents a hydrocarbon group having 1 to 20 carbon atoms and optionally having a substituent; and

n1 to n4 each independently represent an integer of 0 to 4, and

in the formula (II),

R 3 represents an aliphatic unsaturated hydrocarbon group having 2 to 20 carbon atoms and optionally having a substituent;

Z 3 represents a single bond or an oxygen atom;

X 5 to X 12 each independently represent —R 5 , —OR 5 , —SR 5 , a halogen atom, a nitro group, or a sulfamoyl group optionally having a substituent;

R 5 represents a hydrocarbon group having 1 to 20 carbon atoms and optionally having a substituent; and

n5 to n12 each independently represent an integer of 0 to 4.

2 . A colored resin composition comprising the compound according to claim 1 and a resin.

3 . The colored resin composition according to claim 2 , comprising a polymerizable compound and a polymerization initiator.

4 . A color filter formed from the colored resin composition according to claim 3 .

5 . A display device comprising the color filter according to claim 4 .
