Abstract

1,243,714. Methine dyes. EASTMAN KODAK CO. 21 March, 1969 [25 March, 1968]. No. 14902/69. Heading C4P. [Also in Divisions C2 and H1] Methine dyes comprise first and second heterocyclic nuclei joined by a mono-, di- or tri-methin linkage, the first nucleus being bonded by a. carbon atom and comprising a pyrylium or thiapyrylium nucleus (optionally in fused form), and the second nucleus being a 2-aryl-indolyl-3, carbazolyl-3 or imidazo- [4,5-b]-quinoxalinyl-2 nucleus. Preferred dyes are of formulµ (in which one of A and A 1 is of one of the formnlµ and the other is H, alkyl or optionally substituted aryl; R 2-4 are each H, alkyi or optionally substituted aryl, or R 3-4 together form a benzo or naphtho group; R 5-7 are each H, halogen, alkyi or nitro, or R 5 and E 6 or R 6 and R 7 together form a benzo group, Or R 5 and R 1 together form an alkylene group; R 1 , if not combined with R 5 is optionally substituted alkyl ; Rg is optionally substituted aryl; R 9 is alkyl; R 10 and R 11 are each alkenyl or optionally substituted alkyl or aryl; D is O or S; X is an anion; Q is C 2-3 alkylene). Specified first nuclei are pyrylium containing a substituent Q as defined above, naphtho-[1,2-b] pyrylium, 1 – benzopyrylium, 5,6,7,8 – tetrahydrobenzo – [b] – pyrylium, 8,9,10,11 – tetrahydrobenzo-[a]-xanthylium, and the thia analogues of these groups. Specified second nuclei are those shown in the above formulµ, and 3- benz-[g] – indolyl. Specified substituents on the first nucleus include naphthyl, p-tolyl, chlorophenyl, and methoxyphenyl; specified substituents on the second nucleus include allyl and N0 2 . The dyes are prepared by the usual condensation reaction.
