Disse er faste, krystallinske stoffer som These are solid, crystalline substances which

des til fargeskrivning på papir som er belagt med eller fylt med slike absorbentstof-fer. Videre er de meget stabile overfor lys og atmosfærisk stabile både i leukaramin-form og i farget tilstand. des for color writing on paper that is coated with or filled with such absorbent substances. Furthermore, they are very stable to light and atmospherically stable both in leucaramine form and in the colored state.

Den for tiden største kjente fordel ved disse forbindelser er at de kan anvendes i overføringsbelegg, som benyttes til mang-foldiggjørelse, hvor baksiden av et overliggende ark av nedtegningsmateriale er belagt med en komposisjon som består av en eller flere leukauraminderivater, mens det underliggende ark inneholder partikler av det sure reaksjonsstoff. I slike mang-foldiggjørelsessystemer er leukauramin-derivatet som regel oppløst i et pasesnde oppløsningsmiddel og forefinnes som små dråper i et hydrofilt kolloidalt tynt belegg på baksiden av et overliggende ark. Når de to ark berører hverandre og det ved skriv-ning utøves et trykk på oversiden av det overliggende ark brytes filmen i stykker ved de punkter hvor trykk utøves, og den flytende oppløsning frigis lokalt, slik at den kan adsorberes av de sure partikler i belegget på det underliggende ark. Ved denne berøring fremkommer det blå eller blågrønne merker på oversiden av det underliggende ark, der hvor trykket opptrer. The currently greatest known advantage of these compounds is that they can be used in transfer coatings, which are used for multiplexing, where the back of an overlying sheet of drawing material is coated with a composition consisting of one or more leukauramine derivatives, while the underlying sheet contains particles of the acidic reactant. In such multiplexing systems, the leukauramine derivative is usually dissolved in a suitable solvent and is present as small droplets in a hydrophilic colloidal thin coating on the back of an overlying sheet. When the two sheets touch each other and, during writing, pressure is exerted on the upper side of the overlying sheet, the film breaks into pieces at the points where pressure is applied, and the liquid solution is released locally, so that it can be adsorbed by the acidic particles in the coating on the underlying sheet. When this is touched, blue or blue-green marks appear on the upper side of the underlying sheet, where the pressure occurs.

De halogeniserte derivater av N-fenyl-leukaramin er langt bedre egnet for mang-foldiggjørelsessystemer enn de kjente ikke halogeniserte derivater, fordi de er mindre flyktige, er mere oppløselige i olje, og er langt mere stabile i sin leukoform når de utsettes for atmosfæriske forhold og for lys. Leukauraminderivatene er også nyt-tige i fast, pulverisert form, som ett av to faste materialer som er dispergert i et be- The halogenated derivatives of N-phenyl-leucaramine are far better suited for multiple multiplication systems than the known non-halogenated derivatives, because they are less volatile, are more soluble in oil, and are far more stable in their leucoform when exposed to atmospheric conditions and too light. The leukauramine derivatives are also useful in solid, powdered form, as one of two solid materials dispersed in a

legg på den ene side av et nedtegningsark, hvor det annet materiale utgjøres av et av de sure anorganiske stoffer som bevirker åt en blå eller blågrønn farge opptrer når det markeres ved hjelp av en skrivestift. place on one side of a drawing sheet, where the other material is made up of one of the acidic inorganic substances which cause a blue or blue-green color to appear when marked with a writing pen.

En framgangsmåte til fremstilling av forbindelsene består deri at man konden-serer molare ekvivalenter av Michler's hydrol og et passende, halogenert anilin i varm etylalkohol, hvoretter man konsen-trerer reaksjonsblandingen så meget at det opptrer utfeining ved avkjøling, filtrerer, renser det rå materiale ved at en bensolisk opløsning av det behandles med f uller jord og aktivt kull, hvoretter man feller ut reak-sjonsproduktet ved tilsetning av petroleumeter. A procedure for the preparation of the compounds consists in condensing molar equivalents of Michler's hydrol and a suitable, halogenated aniline in hot ethyl alcohol, after which the reaction mixture is concentrated to such an extent that a clarification occurs on cooling, filtering, purifying the raw material by that a benzolic solution of it is treated with fuller's earth and activated charcoal, after which the reaction product is precipitated by the addition of petroleum ether.

Leukaramin har den i fig. 3 viste struktur og dets derivater i henhold til oppfinnelsen fåes ved at en halogensubstituert fenylgruppe innføres i stedet for et av de vannstoffatomer som er tilknyttet (l)N-atomet i atombindingen. Leukaramin has the one in fig. The structure shown in 3 and its derivatives according to the invention are obtained by introducing a halogen-substituted phenyl group in place of one of the hydrogen atoms associated with the (l)N atom in the atomic bond.

Som et første spesifikt eksempel på fremgangsmåten skal vi se på fremstilling av N-(o-klorfenyl)-leukauramin: Man løser opp 25,6 g (0,2 mol) o-kloranilin, og 54,0 g (0,2 mol) Michler's hydrol i 200,0 g etylalkohol i en rundbunnet kolbe, As a first specific example of the procedure, we will look at the production of N-(o-chlorophenyl)-leukauramine: 25.6 g (0.2 mol) o-chloroaniline is dissolved, and 54.0 g (0.2 mol ) Michler's hydrol in 200.0 g of ethyl alcohol in a round-bottomed flask,

som er utstyrt med en vannavkjølet til-bakeløpskondensator. Oppløsningen opp-varmes, med tilbakeløpskjøling, i 4 timer på et dampbad, hvoretter oppløsningen får avkjøle seg til romtemperatur. De utskilte krystaller filtreres fra og vaskes med litt kold etylalkohol. Filtratet kan konsentre- which is equipped with a water-cooled to-reflux condenser. The solution is heated, with reflux cooling, for 4 hours on a steam bath, after which the solution is allowed to cool to room temperature. The separated crystals are filtered off and washed with a little cold ethyl alcohol. The filtrate can concentrate

O-bromfenyl, m-bromfenyl og p-brom-fenylderivatene kan fremstilles ved at man The o-bromophenyl, m-bromophenyl and p-bromophenyl derivatives can be prepared by

Similarly, dichlorophenyl, trichlorophenyl, tetrachlorophenyl, dibromophenyl, tribromophenyl and tetrabromophenyl derivatives can be prepared by using the appropriate halogenated aniline in the same molecular proportions.

Som et annet spesifikt eksempel kan nevnes fremstilling av N-(2,4-diklorfenyl)-leukauramin. Det anvendes 32,4 g (0,2 mol) 2,4-dikloranilin og 54,0 g (0,2 mol) Mich- As another specific example, the production of N-(2,4-dichlorophenyl)-leukauramine can be mentioned. 32.4 g (0.2 mol) of 2,4-dichloroaniline and 54.0 g (0.2 mol) of Mich-
