Wn z/ hvor X, Y og Z har den i forbindelse med formel (I) angivne betydning, kan fremstilles ved kendte metoder (jvf. f.eks. B. D. J.
Brown, The Pyrimidines, og D. J. Brown, The Pyrimidines Supplement I, i The Chemistry of Heterocyclic Compounds, udg. A. Weissberger og E. C. Taylor, Wiley-Interscience, New York, 1962 og 1970). Man cycliserer f.eks. urinstof eller guanidin-derivater med formlen 6 U3944 τ HN«.
χ (vi) h2n hvor X har den ovenfor angivne betydning, med malonester, cyan-ethylacetat eller malodinitril.
Som egnede koblingskomponenter skal f .eks. nævnes: 2-cyanamino-4,6--dihydroxy-pyrimidin, 2-cyanamino-4-amino-6-hydroxy-pyriitiidin, 2-cyanamino-4,6--diamino-pyrimidin, 2-ureido-4,6-dihydroxy-pyrimidin, 2-ureido--4-amino-4-hydroxy-pyrimidin, 2-ureido-4,6-diamino-6-hydroxy--pyrimidin, 2-acetylamino-4,6-dihydroxy-pyrimidin, 2-acetylamino--4-amino-6-hydroxy-pyrimidin, 2-acetylamino-4,6-diamino-pyrimidin, 2-benzoylamino-4,6-dihydroxy-pyrimidin, 2-benzoylamino-4-amino--6-hydroxy-pyrimidin, 2-benzoylamino-4,6-diamino-pyrimidin, 2-methylsulfonylamino-4,6-dihydroxy-pyrimidin, 2-methylsulfonyl-amino-4-amino-6-hydroxy-pyrimidin, 2-methylsulfonylamino-4,6--diamino-pyrimidin, 2-guanidino-4,6-dihydroxy-pyrimidin, 2-guani-dino-4-amino-6-hydroxy-pyrimidin, 2-guanidino-4,6-diamino-pyrimidin, 2-phenylsulfonylamino-4,6-dihydroxy-pyrimidin, 2-phenylsulfonyl-amino-4-amino-6-hydroxy-pyrimidin og 2-phenylsulfonylamino-4,6--diamino-pyrimidin.
De her omhandlede farvestoffer fremkommer, når man dia-zo.terer aminerne a-nh2 og omsætter dem med koblingskomponenter med formel (III). Der arbejdes hensigtsmæssigt i vandig opløsning.
Det er hyppigt fordelagtigt at arbejde i nærværelse af et ikke-ionogent, kation- eller anionaktivt dispergeringsmiddel, f.eks. et alkylsulfonat og/eller et polykondensationsprodukt ud fra octylalkohol og ethylenoxid og/eller i nærværelse af et organisk opløsningsmiddel. I betragtning som sådanne kommer helt eller delvis vandblandbare forbindelser, såsom alkoholer, f.eks. methyl-eller ethylalkohol, glycol, glycolmonomethylether, butylglycol, lavere ketoner, f.eks. acetone, tertiære nitrogenforbindelser, såsom pyridin, dimethylformamid eller N-methylpyrrolidon, samt også vandublandbare, eventuelt halogenerede eller nitrerede carbon- U3944 7 hydrider, såsom toluen, chlorbenzen eller nitrobenzen. Eventuelt kan der endvidere også tilsættes koblingshjælpemidler, f.eks. urinstof.
En anden mulighed for fremstillingen består i at koble malonester, cyanethylacetat eller malodinitril med den tilsvarende diazoterede amin og kondensere den fremkomne azoforbindelse på den i fransk patentskrift nr. 1.453.812 angivne måde med en forbindelse med formlen H2N\

med tilsvarende acylhalogenider.
Ved alment kendte metoder isoleres, vaskes, tørres og pulveriseres farvestofferne. De kan dernæst anvendes direkte som pigmenter. Undertiden er det dog fordelagtigt at underkaste de fremkomne forbindelser en efterbehandling til forbedring af deres egenskaber, især kornblødhed og farvestyrke, idet man opvarmer dem i et organisk opløsningsmiddel, såsom n-^butanol, pyridin, di-methylformamid, benzen, toluen, chlorbenzen eller nitrobenzen.
De hidtil ukendte farvestoffer er vanskeligt opløselige i de gængse opløsningsmidler. De er derfor egnede til pigmentering af lakker af enhver art, til fremstilling af tryk-, lim-r· eller bindemiddelfarver, til massefarvning af syntetiske, halvsyntetiske eller naturlige makromolekylære stoffer, såsom polyvinylchlorid, polystyren, polyamid eller polyethylen. De kan også anvendes til farvning i spindemassen af naturlige, regenererede eller kunstige fibre, f.eks. af cellulose-, polyester-, polycarbonat-, polyacrylo-nitril- eller polyamidfibre, samt til trykning af tekstiler og papir. Ud fra disse pigmenter kan der ved formaling eller æltning 143944 8 i nærværelse af ikke-ionogene, anioniske eller kationiske tensider fremstilles findelte, stabile, vandige pigmentdispersioner, der f.eks. er anvendelige til pigmentering af dispersions- og udstrygningsfarver, til papirfarvning, til pigmenttrykning af tekstiler og til farvning i spindemassen af viscose.
Eksempel 1 15,1 g 2-aminobenzoesyremethylester omrøres i 100 ml vand, og 30 ml 10 N saltsyre tilsættes ved 0°C. Der diazoteres med 7 g NaNOj i 20 ml vand, efteromrøres 1/2 time, og nitritoverskuddet ødelægges med amidosulfonsyre.
17,3 g 2-cyanamino-4-amino-6-hydroxy-pyrimidin opløses som natriumsalt i 250 ml vand. Dernæst tilsættes 1 g af en blanding af et langkædet alkylsulfonat og produktet ud fra oleyl-alkohol (1 mol) og ethylenoxid (20 mol) samt 2 g harpikssæbe.
Der afkøles til 10°C og fældes med 25 ml 5 N saltsyre. Til denne blanding lader man diazoniumsalt-opløsningen strømme, og reaktionsblandingen pufres ved tilsætning af 100 ml af en 20%'s natrium-acetatopløsning.
