Heterocyclic compounds useful as dyes: Heterocyclic compounds useful as dyes. Rolf, Meinhard; Neeff, Ruetger; Mueller, Walter (Bayer A.-G., Ger.). Ger. Offen. DE 2644265 6 Apr 1978, 38 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07D239-90. APPLICATION: DE 76-2644265 30 Sep 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Condensation of anthranilamides with malonic acid derivs. gives I (R = C1-4 alkyl or both R groups together represent CO; R1 = a substituent; n = 0-4), which can be coupled with diazotized arom. or heterocyclic amines (Z(NH2)m, m = 1 or 2) to form azo compds. (II; groups, m, and n as described) useful as fast pigments for plastics, coatings, paper, etc. Thus, di-Et malonate [105-53-3] was condensed with anthranilamide [88-68-6] in o-C6H4Cl2 contg. pyridine at 150-70° to give I (R = R1 = H) (III) [66755-25-7], a yellow powder m. >300°. Coupling III with diazotized 1-amino-5-benzamidoanthraquinone [117-06-6] gave II (R = R1 = H, Z = 5-benzamidoanthraquinon-1-yl, m = 1) [66755-26-8], a fast orange pigment.

Chromogenic quinazolone compounds: Chromogenic quinazolone compounds. Zink, Rudolf; Fletcher, Ian John (Ciba-Geigy A.-G. , Switz.). Ger. Offen. 92681-81-7 is the cas registry number. This chemical is also mentioned in this article. DE 3423369 A1 10 Jan 1985, 28 pp. (German). (Germany). CODEN: GWXXBX. CLASS: ICM: C07D403-04. ICS: C07D405-04; C07D417-04; C09B011-26; C09D005-26; B41M005-16; B41M005-18. APPLICATION: DE 84-3423369 25 Jun 1984. PRIORITY: CH 83-3521 28 Jun 1983. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 42, 43 Chromogenic quinazolones (I) for heat- or pressure-sensitive record materials are prepd., where R represents H, (un)substituted C1-12 alkyl, cycloalkyl, (un)substituted Ph, or (un)substituted benzyl; R1 is a(n) (un)substituted nonarom. heterocyclic radical bound to the quinazoline through a fused benzene ring; and ring A may contain halogen, CN, NO2, lower alkyl, lower alkoxy, or lower carbalkoxy substituents. I produce light- and sublimation-fast yellow or orange colors when in contact with a developer. A typical quinazolone, II [92681-81-7], was prepd. by condensing N-ethyl-2,2,4-trimethyltetrahydroquinoline-6-carboxaldehyde [80162-58-9] with anthranilamide [88-68-6] at 60° in EtOH in the presence of H2SO4, followed by bisulfite oxidn. of the tetrahydroquinazolone intermediate [95545-30-5].In this experiment, several chemicals are used like 92681-81-7 Eleven other I were similarly prepd. II gave a strong greenish yellow color when developed on acidic clay, and its use in heat- and pressure-sensitive record systems is disclosed in detail. ..
