Anionic phthalocyanine compounds which, in the free acid form, have the Formula (1):
wherein:
Pc is a metal-containing phthalocyanine nucleus;
R1, R2 and R3 are each independently H, alkyl, substituted alkyl, alkenyl, substituted alkenyl, aralkyl or substituted aralkyl;
L is a divalent organic linking group;
each X independently is carbonyl or a group of formula (2), (3) or (4):
each Z independently is NR4R5, SR6 or OR6;
each Y independently is H, Cl, Z, SR7 or OR7;
each E independently is CI or CN;
R4, R5, R6 and R7 are each independently H, alkyl, substituted alkyl, aryl, substituted aryl, aralkyl or substituted aralkyl or R4 and R5 together with the nitrogen atom to which they are attached form a 5 or 6 membered ring;
G is a colourless organic radical substituted by one or two groups selected from COSH and COOH; and
(t+q) is from 3 to 4 inclusive.
The compounds are useful for the preparation of inks for use in ink-jet printing.
