Abstract
Official abstract text for this publication.
The present invention provides a water-insoluble coloring compound having a high solvent solubility, showing increased brightness and saturation, and being useful for increasing the green gamut and also provides an ink containing the water-insoluble coloring compound. The present invention provides a thermal transfer recording sheet including a coloring material layer formed on a base material from the ink and also provides a color filter resist composition showing an increased green gamut due to the ink.
First claim
Opening claim text (preview).
The invention claimed is: 1. A water-insoluble coloring compound having a structure represented by Formula (1): in Formula (1), R 1 represents an alkyl group, an aryl group, or an amino group; R 2 represents a carboxylic acid ester, a carboxylic acid monoalkylamide or a carboxylic acid dialkylamide; A represents a carbonyl group or a sulfonyl group; and R 3 and R 4 each independently represent an n-butyl group, an octyl group, a cyclohexyl group, a 2-ethylhexyl group, a dodecyl group or a phenyl group. 2. The water-insoluble coloring compound according to claim 1 , wherein in Formula (1), R 3 and R 4 are the same functional group. 3. The water-insoluble coloring compound according to claim 1 , wherein in Formula (1), R 2 is a carboxylic acid ester. 4. An ink comprising the water-insoluble coloring compound according to 1. 5. A thermal transfer recording sheet comprising a base material and a coloring material layer formed on the base material from a composition containing the water-insoluble coloring compound according to claim 1 . 6. A color filter resist composition comprising the water-insoluble coloring compound according to claim 1 . 7. The water-insoluble coloring compound according to claim 1 , wherein in Formula (1), R 3 and R 4 each independently represent a n-butyl group or a 2-ethylhexyl group. 8. The water-insoluble coloring compound according to claim 1 , wherein in Formula (1), both R 3 and R 4 represent a 2-ethylhexyl group.
