<p>Suitable phthalocyanine compounds of Formula (1) have utility as colorants in inks for inkjet printing 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 substitued 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 indepentently comprising at least one of: an optional substituent and optionally substituted C¿1-15?hydrocarbyl; 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 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 substituents comprise at least one of; carboxy, sulpho, hydroxy, amino, mercapto, cyano, nitro and halo. There is also disclosed a process for inkjet printing a substrate with such an ink. The substrate so-printed may be selected from one or more of: paper, an overhead projector slide and a textile material.</p> |
