CLASS: IC: C09D011-00. APPLICATION: JP 76-61391 27 May 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Water-thinned inks with good water resistance as well as good slow-drying properties contained basic and acid dyes and sedimentation preventors. For example, an ink from water 60, HOCH2CH2OH 25, ethylene glycol monolaurate [4219-48-1] 5, C.I. Acid Yellow 42 [6375-55-9] 5, and C.I. Basic Blue 5 [3943-82-6] gave writings with good water resistance and drying time (for tip of a pen contg. the ink at 30° and relative viscosity 60%, until the pen became unusable) 10 days.

Evaluation of the migration of Astrazon-type dyes from wool to polyacrylonitrile during dyeing of blends of wool and polyacrylonitrile fibers: Evaluation of the migration of Astrazon-type dyes from wool to polyacrylonitrile during dyeing of blends of wool and polyacrylonitrile fibers. Malinowska-Grabos, Zdzislawa (Inst. Wiok., Politech. Lodzk., Bielsko-Biala, Pol.). Przegl. Wlok., 38(5), 200-2 (Polish) 1984. CODEN: PRZWAZ. ISSN: 0033-2410. DOCUMENT TYPE: Journal CA Section: 40 (Textiles) In dyeing of acrylic fiber-wool blends with Astrazon cationic dyes, the dyes were first bonded to wool and then migrated to acrylic fibers. The course of exhaustion depended on dye type; Astrazon Green F3BL (I) [69771-44-4] and Astrazon Blue B [3943-82-6] were exhausted to 80-90% within 15 min, whereas the concn. of Astrazon Yellow 3GL (II) [4208-80-4], Astrazon Golden Yellow GL (III) [54060-92-3], Astrazon Orange G (IV) [3056-93-7] and Astrazon Orange RRL [61724-64-9] decreased in the 1st, then increased, and finally decreased with prolonged dyeing. This is explained by partial dye pptn. during initial dyeing, dye adsorption on fibers, and migration from wool to acrylic fibers. I is strongly bonded to wool, showing almost no migration to acrylic fibers, while the other dyes, esp. II, III, and IV, migrated easily from wool to acrylic fibers. II, III, IV, and Astrazon Blue FGG [93792-53-1] are best for dyeing acrylic-wool blends.
