WATER-INSOLUBLE DYE COMPOUND, INK, THERMOSENSITIVE TRANSFER RECORDING SHEET, AND RESIST COMPOSITION FOR COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a water-insoluble dye compound which has high solubility in a solvent and good spreads of brightness and saturation and is useful for widening the color gamut of green, and to provide an ink containing the water-insoluble dye compound, a thermosensitive transfer recording sheet comprising the water-insoluble dye compound, and a resist composition for color filters.SOLUTION: A water-insoluble dye compound has a structure shown by a general formula (1) (wherein Ris an alkyl, aryl or amino group; Ris carboxylic acid ester or carboxylic acid amide; A is a carbonyl or sulfonyl group; Rand Rare each an alkyl or aryl group independently).
