摘要
Inks are provided comprising (a) a dye corresponding to the formula whereinW is COOH,X is H, or COOH,Y is H, COOH, or SO₃H,Z is H, COOH, or SO₃H, andR is H, CH₂COOH, or CH₂CH₂COOH;with the proviso that there are at least two COOH groups and that the number of COOH groups is equal to or greater than the number of SO₃ groups, and (b) a solvent which may be water or a mixture of water and a water-soluble organic solvent provide excellent waterfast prints on paper. The inks preferably have a pH from about 7 to about 9.5.
