PHTHALOCYANINE COMPOUNDS AND THEIR USE

摘要

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>; R<2> represents (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 is independently 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
