DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Azo pigments having excellent resistance to light, solvents, and heat were prepd. by coupling arom. diazonium salts with I (R = H, Me, Et, Ph, MeC6H4, MeC6H4, ClC6H4, O2NC6H4). Thus, 3-amino-4-methoxybenzamide [17481-27-5] was diazotized and coupled with 4-(2-hydroxy-3-naphthamido)phthalimide [77281-83-5] to give a bluish red pigment [77281-84-6]. .

APPLICATION: SU 76-2408294 4 Oct 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) The dyeing concn. of the title pigment (I) [67119-75-9], prepd. by diazotizing 3,4-H2N(MeO)C6H3CONH2 [17481-27-5] and coupling with 3,2-HOC10H6(OMe)Me-2,5 [54079-43-5], is increased and its rheol. properties and dispersibility are improved when coupling is done in the presence of 2-6% (based on pigment) p-methoxy-N-octadecylbenzamide [67119-73-7] or 3-hydroxy-N-octadecyl-2-naphthamide [67119-74-8].
