Einerhand, Johan Jozef; Erkens, Leonardus Johannes Hubertus; Laenen, Rene Johannes; Hoofs, Joseph Wilhelmus Jacobus (Ten Horn Pigmentchemie B. V., Neth.). Neth. Appl. NL 7607496 10 Jan 1978, 10 pp. (Dutch). (Netherlands). CODEN: NAXXAN. CLASS: IC: C09C001-26. APPLICATION: NL 76-7496 7 Jul 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Iron blue [12240-15-2] flush colors with increased pigment content are manufd. by using a combination of surfactants contg. 31 amine and 31 poly(ethylene oxide). Thus, iron blue 500, paraffinic mineral oil 260, 1-(hydroxyethyl)-2-heptadeceneylimidazoline [21652-27-7] 10, and polyethylene glycol oleyl ether (I) [9004-98-2] 7.5 parts were kneaded, freed of the sepd. water, evacuated, warmed, mixed with 6.5 parts I, and kneaded, giving a smooth, readily mixable paste with pigment content 59.5%.

Steam temperature-sensitive printing inks in sterilization. (Toppan Printing Co., Ltd., Japan). Jpn. Tokkyo Koho JP 59013550 B4 30 Mar 1984 Showa, 3 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C09D011-00. APPLICATION: JP 75-43615 10 Apr 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Printing inks indicating steam temps. during sterilization contain Prussian blue (I) [12240-15-2] and alkalies dispersed solns. of nitrocellulose (II) [9004-70-0] and polyesters. The indicated temp. can be varied by changing the ratio of the binder mixt. Thus, an ink contg. II 15.6, I 3.1, CaCO3 31.3, iso-PrOH 15, and MEK 35% changed color on exposure to 110° steam for 5 min, compared with 130° with 12.0% II and 3.6% polyester.
