摘要

Phthalocyanine compounds of formula (1) have utility as colorants in inks for ink-jet printing, which includes all IJP-effective forms of such compounds; and in which: M represents a metal or H; A represents C1-4alkylene; Pc represents a phthalocyanine nucleus of formula (2); D represents NR4R5 or SC1-4alkyleneSO3H; R1, R2, and R3 each independently represents H or C1-4-alkyl; R4 represents H; or C1-4-alkyl optionally substituted by hydroxy; R5 represents C1-4alkyl optionally substituted by hydroxy and/or morpholino; or R4 and R5 together with the N atom to which they are attached form a morpholino ring; and x+y+z represents an average of from 3 to 4.
