A mixture of com ounds of Formula (1) and salts thereof: wherein: M is 2H, Si, a metal, an oxymetal group, a hydroxymetal group or a halometal group; Pc represents an phthalocyanine nucleus of formula (1a); R1 is H or optionally substituted C1-4alkyl; R2 is H or optionally substituted C1-8alkyl; R3 is H or optionally substituted hydrocarbyl; and R4 is optionally substituted hydrocarbyl; or R3 and R4 together with the nitrogen atom to which they are attached represent an optionally substituted aliphatic or aromatic ring system; each R5 is independently H or optionally substituted C1-4alkyl, provided that at least one R5 is optionally substituted C1-4alkyl; x is 0 to 4; y is 0 to 4; z is greater than 0 to 4; the sum of x+y+z is in the range of from 2 to 4; and the substituents, represented by x, y and z, are attached only to a β-position on the phthalocyanine ring and the substituents represented by y and z are different. Also compositions, inks, printing processes, printed materials and ink-jet cartridges.
Synthesis and Characterisation of some 1,4,8,11,15,18,22,25-Octa-alkyl- and 1,4,8,11,15,18-Hexa-alkyl-22,25-bis(carboxypropyl)phthalocyanines

A series of 3,6-dialkylphthalonitriles and 3,6-bis(4,4,4-trimethoxybutyl)phthalonitrile have been prepared via Diels-Alder reactions of 2,5-disubstituted furans or thiophene 1,1-dioxides with fumaronitrile.The phthalonitriles were converted into the title phthalocyanines as metal-free and copper(II) derivatives.The macrocycles were characterised using 1H NMR and optical spectroscopy, and fastatom bombardment spectrometry.Certain examples exhibit discotic liquid crystal behaviour.
