DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Azoxybenzene derivs. were reduced in 1 step with com. 961-28-4 and 97-36-9 which are cas registry numbers are also used here. NaSH (aq. soln.) in EtOH, MeOH, DMF, morpholine, Me2SO, or iso-BuOH to give hydrazobenzenes which could be used without further purifn. for benzidine-based diazo pigment manuf. For example, 53.4 parts 2,2'-dichloroazoxybenzene [13556-84-8] in MeOH was treated with 85 parts aq. NaSH (35% NaSH, 12% Na2S2O3) over 90 min and refluxed for 7.5 h to give 80% 2,2'-dichlorohydrazobenzene (I) [782-74-1] which was rearranged to benzidine deriv. in usual manner, tetrazotized, and coupled with acetoacetanilide [102-01-2] to give 89% (based on I) C.I.

DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Pigments for inks are coated with 0.01-1% higher fatty acid-modified silicone oil and used to prep. inks which have good abrasion resistance, transparency, and adhesion when dry. Thus, a suspension contg. 63 parts Pigment Yellow 12 [6358-85-6] was mixed with 0.2% X-22-800 (silicone oil, 2% emulsion), stirred 1 h at 40°, filtered, dried, pulverized, mixed (30 parts) 20 h with 110 parts polyamide- or vinyl acetate-vinyl chloride copolymer [9003-22-9]-based varnish (35% solids) and 40 parts thinner and 1 h with 100 parts varnish and 20 parts thinner, and printed on a film, giving an ink having better abrasion resistance, transparency, and adhesion than an ink contg. a pigment treated with 0.1% polyethylene wax instead of the silicone oil. .
