Indandione bisazomethine pigments. Ando, Hirohito; Takagi, Koichi; Shukuya, Masao (Dainippon Ink and Chemicals, Inc., Japan). Japan. Kokai JP 52027429 1 Mar 1977 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09B057-00. APPLICATION: JP 75-103501 28 Aug 1975. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Pigments (RCH:N)2Z [I, R = R1, R2; R3, R5, R6 = H, Cl, Br; R4 = H, Cl, Br, NO2; R3R4 = benzo; R4R5 = benzo (tetrabromo); Z = 2,5-dimethyl-1,4-phenylene, 3,3'-dimethoxy-1,1'-biphenyl-4,4'-diyl, 4-C6H4NHC6H4-4, benzothiazole-2,5-diyl, toluene-2,6-diyl, Z1] for plastics, printing inks, and coatings were prepd. For example, 2-formyl-4,5,6,7-tetrachloroindan-1,3-dione [63968-95-6] was treated with 2,5-dimethyl-1,4-phenylenediamine [6393-01-7] in DMF at 100.degree.There are some reagents like 63971-19-7 is used in this study. for 2 h to give I (R = R2; R3 = R4 = R5 = R6 = Cl; Z = 2,5-dimethyl-1,4-(phenylene) [63968-99-0], lightfast orange in polyethylene [9002-88-4]. .

Disazo pigments

Disazo pigments. Ronco, Karl (Ciba-Geigy A.-G. , Switz.). Eur. Pat. Appl. EP 95442 A1 30 Nov 1983, 14 pp. DESIGNATED STATES: R: CH, DE, FR, GB, IT, LI.In this article, certain chemicals are used. Some of their cas registry numbers are 89037-97-8 and 89037-98-9 (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09B043-38. ICA: C09B033-147; C08K005-23. APPLICATION: EP 83-810203 11 May 1983. PRIORITY: CH 82-3083 18 May 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 37, 42 Brown pigments of general structure I are described, where R = C1-6 alkyl or cycloalkyl and R1 and R2 = H, Cl, Me or C1-4 alkoxy. I are fast colorants for plastics and coatings. A typical product, I (R = R1 = R2 = Me) [89037-99-0], was prepd. by reaction of 2,4-MeO2C(O2N)C6H3N:NC10H5(OH)COCl-1,2,3 [89037-98-9] with 2,5-dimethyl-1,4-phenylenediamine [6393-01-7] and gave brown dyeings with excellent fastness to heat, light, weathering, and migration when incorporated in PVC [9002-86-2], polyolefins, or lacquers. .
