Abstract
An object is to provide a compound having high color developability and excellent heat resistance, and a resist composition for a color filter and a color filter that contain the dye composition. Another object is to provide a dyed polyamide fiber product having excellent wet rubbing fastness. The objects are achieved by a compound represented by the following general formula (1):
Claims7
A compound represented by the following general formula (1):
- wherein
- R1 each independently represent a straight-chain or branched alkyl group having 5 carbon atoms,
- R2 represents a hydrogen atom, a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, and
- R3 and R4 each independently represent a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, wherein
- at least one of R2 to R4 is a sulfonato group.
A resist composition for a color filter comprising the compound represented by the following general formula (1):
- wherein
- R1 each independently represent a straight-chain or branched alkyl group having 5 carbon atoms,
- R2 represents a hydrogen atom, a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, and
- R3 and R4 each independently represent a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, wherein
- at least one of R2 to R4 is a sulfonato group.
A color filter comprising the compound represented by the following general formula (1):
- wherein
- R1 each independently represent a straight-chain or branched alkyl group having 5 carbon atoms,
- R2 represents a hydrogen atom, a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, and
- R3 and R4 each independently represent a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, wherein
- at least one of R2 to R4 is a sulfonato group.
A polyamide-containing dyed fiber dyed with the compound represented by the following general formula (1):
- wherein
- R1 each independently represent a straight-chain or branched alkyl group having 5 carbon atoms,
- R2 represents a hydrogen atom, a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, and
- R3 and R4 each independently represent a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, wherein
- at least one of R2 to R4 is a sulfonato group.
A method for dyeing a polyamide-containing fiber comprising contacting the compound represented by the following general formula (1) with the polyamide-containing fiber.
- wherein
- R1 each independently represent a straight-chain or branched alkyl group having 5 carbon atoms,
- R2 represents a hydrogen atom, a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, and
- R3 and R4 each independently represent a sulfo group, a sulfonate group, a sulfonato group, or a sulfonamide group, wherein
- at least one of R2 to R4 is a sulfonato group.
