<p>An ink in which a dye and a liquid carrier medium are present. The ink includes a dye comprising a compound represented by the following general formula (I). <CHEM> wherein Ph is a copper or nickel phthalocyanine residue, M is an alkali metal or ammonium, R1 and R2 are each H, -(CH2CH2O)m-R3 or -(CH2CHOH)m-R3 in which R3 is H, CH3, C2H5 or CH2OH and in which m is a number from 0 to 4, a is a number from 0 to 2, X is a lower alkylene or phenylene group, C is a number from 2 to 3, and b is a number from 0 to 2 with the proviso that when b is 0, then Y and Z are respectively Cl, OH or OR4 wherein R4 is an alkyl group having 1 or 2 carbons or a hydroxyalkyl group, and when b is not 0, then Y is Cl, NR5R6 or OR7 and Z is NR5R6, OR7, a substituted or unsubstituted anilino group or a substituted or unsubstituted phenoxy group, wherein R5 and R6 are respectively H, an alkyl group, an alkylalkoxy group or a hydroxyalkyl group and have 4 or less carbons in total and, wherein R7 is H, an alkyl group having 1 to 3 carbons or a substituted or unsubstituted phenyl group.</p> |
