Color-stable monoazo dye: Color-stable monoazo dye. Deubel, Reinhold; Kruse, Hubert; Schladetsch, Hans J.; Steckelberg, Willi (Hoechst A.-G., Ger.). Ger. DE 2511534 2 Sep 1976, 6 pp. (German). (Germany). CODEN: GWXXAW. CLASS: IC: C09B067-00. APPLICATION: DE 75-2511534 17 Mar 1975. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) I [39952-00-6] was prepd. by coupling diazotized 2,4-NC(O2N)C6H3NH2 [17420-30-3] with 2-ClC6H4NHCH2CH2CN [94-89-3] and conditioned to give the color stable .beta.-form by milling at 80. 39952-00-6 and 94-89-3 which are cas registry numbers of substances are two of reagents here.degree. or by heating with org. solvent(s). .

Azo dyes: Azo dyes. Schuendehuette, Karl H.; Reel, Henning (Bayer A.-G., Ger.). Ger. Offen. DE 2513949 7 Oct 1976, 28 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B029-36. 74-89-5 and 61100-29-6 which are cas registry numbers of chemicals are mentioned. APPLICATION: DE 75-2513949 29 Mar 1975. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Sulfo group-free azo dyes (I, R = H, NO2; R1 = CN, NO2, Cl; R2 = H, Me; R3 = NO2, CONHBu, Br, SCN; R4 = H, MeOCH2CH2, Bu, Me) were prepd. and used to dye polyester fibers fast yellow-orange to bluish violet shades. Thus, 2,4-NC(O2N)C6H3NH2 [17420-30-3] was diazotized and coupled with 2,6-diamino-3-nitropyridine [3346-63-2] to give I (R = NO2, R1 = CN, R2 = R4 = H, R3 = NO2) [61100-38-7], yellow-orange on polyester fibers. .
