Anionic phthalocyanine derivatives for use in jet-printing inks: Anionic phthalocyanine derivatives for use in jet-printing inks. Gregory, Peter; Kenyon, Ronald Wynford; Millard, Christine (Imperial Chemical Industries PLC, UK). Eur. Pat. Appl.

These chemicals are also mentioned in this article. CODEN: EPXXDW. CLASS: ICM: C09B062-00. APPLICATION: EP 91-305942 1 Jul 1991. PRIORITY: GB 90-16451 26 Jul 1990. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 42 The title derivs., represented in the free acid form as Pc(SO3H)t(SO2NR1LNR2XNR3Z)q (I), L is a divalent org. group, Pc is a metal-contg. phthalocyanine, R1-R3 are H or (un)substituted alkyl or alkenyl or aralkyl, X is CO or a divalent residue of a substituted s-triazine, pyrimidine, or chloropyridine, Z is a colorless org. radical bearing 1-2 CO2H and/or COSH groups, and (t + q) = 3-4, dissolve in H2O contg. diethylene glycol to form inks which give fast cyan shades when applied to plain paper by jet printing. Cu phthalocyanine was chlorosulfonated with ClSO3H, treated with PCl3, and condensed with H2NCH2CH2NHCH2CH2OH to give CuPc(SO3H)1.4(SO2NHCH2CH2NHCH2CH2OH)2.6, which was condensed with a 1:1 condensate of cyanuric chloride and anthranilic acid and the product treated with ethanolamine to give I (metal = Cu, L = C2H4, R1 = R3 = H, R2 = CH2CH2OH, X = 6-(2-hydroxyethylamino)-s-triazine-2,4-diyl, Z = C6H4CO2H-2, q = 2.6, t = 1.4) (II). II was treated with NH4OH, dialyzed to remove Cl-, and dissolved in 92.5:7.5 H2O-O(CH2CH2OH)2 to give a cyan ink. .
