This chemical is also mentioned in this article. (Unavailable). (Switzerland). CODEN: SWXXAS. CLASS: IC: C09B043-12. APPLICATION: CH 72-2725 25 Feb 1972. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Reacting 1-(2-chlorophenyl)-5-[(2,5-dichlorophenyl)azo]-4-hydroxypyrazole-3-car bonyl chloride (I) [61600-62-2] with arylenediamines or hydroquinone [123-31-9] gave pigments useful for coloring plastics and lacquers. Thus, a mixt. of I 8.3, 2,5-dichloro-p-phenylenediamine [20103-09-7] 1.95, o-C6H4Cl2 300, and pyridine 0.2 part was heated for 10 h at 140-5.degree., and cooled to 100.degree. to give N,N'-(2,5-dichloro-p-phenylene)bis[1-(2-chlorophenyl)-5-[(2,5-dichlorop henyl)azo]-4-hydroxypyrazole-3-carboxamide] [61627-60-9] which colored PVC [9002-86-2] and lacquer to a brown tint. .
