Suitable phthalocyanine compounds of Formula (1) have utility as colorants in inks for ink-jet printing, where Formula (1) represents: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:M represents a metal or H;Pc represents a phthalocyanine nucleus of Formula (2):L represents a linking group comprising an optionally substituted C1-30hydrocarbyl;A represents a group comprising at least one of: amino and optionally substituted C1-30hydrocarbyl 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;R1 represents a group independently comprising at least one of: an optional substituent and optionally substituted C1-5hydrocarbyl;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; andx 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 substituents comprise at least one of: carboxy, sulpho, hydroxy, amino, mercapto, cyano, nitro and halo.
