Claims9
An inkjet ink comprising a dye, water, a water-miscible organic solvent and at least one compound selected from an amino acid derivative containing an oil-soluble group having 6 or more carbon atoms and a metal chelating compound containing an oil-soluble group having 6 or more carbon atoms, wherein the amino acid derivative is a compound represented by the following formula (A):
- wherein RA1 represents an alkyl group having 6 or more carbon atoms, and RA2 and RA3 each represent an alkyl group, a carboxyalkyl group or a sulfoalkyl group, provided that at least one of RA2 and RA3 is a carboxyalkyl group or a sulfoalkyl group.
A concentrated inkjet ink comprising a dye, water, a water-miscible organic solvent and at least compound selected from an amino acid derivative containing an oil-soluble group having 6 or more carbon atoms and a metal chelating compound containing an oil-soluble group having 6 or more carbon atoms, wherein the amino acid derivative is a compound represented by the following formula (A):
- wherein RA1 represents an alkyl group having 6 or more carbon atoms, and RA2 and RA3 each represent an alkyl group, a carboxyalkyl group or a sulfoalkyl group, provided that at least one of RA2 and RA3 is a carboxyalkyl group or a sulfoalkyl group.
