(57) Abstract: Phthalocyanine compounds of Formula (1) have utility as colorants in inks for ink-jet printing,
wherein M represents a metal or H; Pc represents a phthalocyanine nucleus; and R 1 represents H or –(CH2)nR 3 ; or
R 1 and R 2 together with the nitrogen atom to which they are attached represent a 5 or 6-membered ring; where: n
isindependently an integer from 1 to 30; and R 3 is independently a group selected from hydroxy, sulpho, cyano, -
SR 4 , -CO2R 5 , -PO3H2 and –NR 6 R 7 ; where: R 4 , R 5 , R 6 and R 7 independently represent H, C1-30alkyl optionally
substituted by one or more groups selected from hydroxy, mercapto, sulpho, carboxy, cyano and - PO3H2; v is the
valence of Pc divided by the valence of M; x is from 1.2 to 3.8; y is from 0.1 to 2.7; z is from 0.1 to 2.7; and x, y
and z satisfy 2 ≤ x + y + z ≤ 4.
