Abstract
Suitable phthalocyanine compounds of Formula (1) have utility as colorants in inks for ink-jet printing, where Formula (1) represents: ##STR1## which comprises any form of the compound: such as salt; stereoisomer, zwitterion, polymorph, complex, isotopic form, combinations thereof in the same species and mixtures thereof; where: PA1 M represents a metal or H; PA1 Pc represents a phthalocyanine nucleus of Formula (2): ##STR2## PA0 L represents a linking group comprising an optionally substituted C.sub.1-30 hydrocarbyl; PA0 A represents a group comprising at least one of: amino and optionally substituted C.sub.1-30 hydrocarbyl comprising at least one protonable nitrogen atom; but where A comprises other than an alkyl group substituted by at least one of: hydroxy, carboxy and sulpho; PA0 R.sup.1 represents a group independently comprising at least one of: an optional substituent and optionally substituted C.sub.1-5 hydrocarbyl; PA0 z represents an integer from 0 to 4; w represents an integer from 1 to 5; and the sum of w+z is from 1 to 5; and PA0 x and y each independently represent a non-zero number; and the mean of the sum of x+y is from about 1 to about 6; where the optional substi…
