APPLICATION: JP 82-160823 17 Sep 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 41 Compns. of water, water-sol. org. solvents, and a mixt. of 30-70% mono-, 0-20% di-, and 30-70% polysulfonated metal phthalocyanine compds. are storage-stable inks suitable for jet printing. Thus, copper sulfophthalocyanine (I) [28901-96-4] 1.5, copper disulfophthalocyanine (II) [29188-28-1] 0.5, copper polysulfophthalocyanine (III) 1.5, ethylene glycol 27, and water 73 g were mixed to form an ink which when stored 3 mo at 60° showed <3% increase in viscosity, and when used in a jet printer formed prints which retained >65% of their color intensity when immersed in water for 5 min 2 days after printing, compared with >10% and <55%, resp., for an ink prepd. similarly with 0.5, 1.8, and 1.0 g of I, II, and III, resp.
