Abstract: Preparation of 7,16-dichlorodianthraquinone-N,N'-dihydroazine (I) by condensing 1-amino-3-chloroanthraquinone (II) in the presence of an alkaline condensing aid, an oxidising agent and a urea derivative (III) (R: identical or different alkyl groups having 1 to 4 carbon atoms which can also be joined together to form a 5- or 6-membered ring containing the urea grouping).

Abstract: New bis(2,4-bis(azulenyl)quadratic acid) dyestuffs (I); and new bis-azulene derivs. (II) are of the formulae (I) and (II). X = CO-O-M-O-CO, CO-NR5-M-NR5-CO, O-CO-M-CO-O or NR5-CO-M-NR5; R5 = H, 1-12C alkyl, 2-12C alkenyl, 5-7C cycloalkyl or (substd.)phenyl; M = 1-12C alkylene, phenylene, biphenylene or (C2H4O)n-C2H4 or (i); n = 1-10; each R6 = H or 1-4C alkyl; Y = H, CN, CO-OR5, CO-NHR5, OR5, O-CO-OR5, NH-CO-R5, NH-CO-OR5 or NH-SO2-R5; L1-L2 independently = a chemical bond or 1-12C alkylene, opt. substd. by phenyl; R1-R4 and Q1-Q4 independently = H or 1-12C alkyl, opt. substd. by halogen, 1-12C alkoxy, (substd.)phenyl, 1-12C alkoxycarbonyl or CN: if R4 and/or Q4 = H, the ring positions of the CH2-L1-X-L1-CH2 and R3 and/or CH2-L2-Y and Q3 substits. may be interchanged.

Abstract: Azulene squaric acid dyes containing ester groups, of the formula in which L denotes C1-C12-alkylene which is optionally substituted by phenyl, R denotes C1-C12-alkyl, mono- or polyunsaturated C1-C12-alkenyl, which can be substituted by phenyl, C5-C7-cycloalkyl, C5-C7-cycloalkenyl, optionally substituted phenyl, pyrrolyl, furanyl, thienyl or pyridyl and R , R , R and R independently of one another denote hydrogen or optionally substituted C1-C12-alkyl, with the proviso that if R denotes hydrogen, the ring positions of the substituents CH2-L-O-CO-R and R on one or both azulene rings can also be interchanged with one another within an azulene ring, their intermediates and an optical recording medium which contains the novel dyes.
