ning av dette problem. De eneste diazo-oksyder av aromatiske sulfonamider som nevnes i dette patent er nemlig de som er avledet fra |5-naftylamid. Det turde være selvinnlysende at det ikke foreligger noen ning of this problem. Namely, the only diazo oxides of aromatic sulfonamides mentioned in this patent are those derived from β-naphthylamide. It should be self-evident that there are none

likhet i strukturen av naf tylamid-halvdelen similarity in the structure of the naphthylamide moiety

og de høymolekylære alicykliske halvdeler som den foreliggende oppfinnelse dreier seg om. and the high molecular weight alicyclic moieties to which the present invention relates.

Denne strukturforskjell gir seg også til kjenne ved en forskjell i diazooksydenes egenskaper. I det tyske patent nevnes som det eneste oppløsningsmiddel for dets diazooksyder dioksan, og i denne forbindelse This structural difference is also manifested by a difference in the properties of the diazo oxides. In the German patent, dioxane is mentioned as the only solvent for its diazo oxides, and in this connection

henvises det til eksempel I. Dette er et meget kraftig oppløsningsmiddel, hvilket refer to example I. This is a very powerful solvent, which

fremgår av at det er i stand til å oppløse de harpikser som er nevnt av patentinne-haveren. Diazooksydene i nærværende krav derimot er oppløselige i enkle organiske opløsningsmidler, som ikke har noen innvirkning på harpikssubstrater. Det foreligger derfor en klar forskjell mellom oppfinnelsen i det tyske patent og i kravet. I Oppfinnerne har funnet, at diazo-oksyder av aromatiske sulfonamider, i hvilke substituenten på amidokvelstoffet er et høymolekylært alicyklisk radikal, har meget fordelaktige egenskaper som sensiti-veringsmidler for litografiske plater. Således har disse forbindelser en struktur av mettet, ikke konjugert, ikke polar karakter, hvorfor de er lett oppløselige i vanlige organiske oppløsningsmidler, og dette til tross for at disse forbindelser har en meget høy molekylarvekt, d. v. s. noe over 1000. appears from the fact that it is able to dissolve the resins mentioned by the patent holder. The diazo oxides in the present claim, on the other hand, are soluble in simple organic solvents, which have no effect on resin substrates. There is therefore a clear difference between the invention in the German patent and in the claim. I The inventors have found that diazo oxides of aromatic sulfonamides, in which the substituent on the amido nitrogen is a high molecular weight alicyclic radical, have very advantageous properties as sensitizers for lithographic plates. Thus, these compounds have a structure of a saturated, non-conjugated, non-polar character, which is why they are easily soluble in common organic solvents, and this despite the fact that these compounds have a very high molecular weight, i.e. something over 1000.

De diazooksyder det dreier seg om kan mer spesifikt representeres ved de gene-relle formler: The diazo oxides in question can be more specifically represented by the general formulas:

hvor R' — CH2 er et alicyklisk radikal, f. eks. dehydroabietyl, dihydroabietyl, tetrahydroabietyl eller dekstropimaryl, hvor R betegner vannstoff, alkyl som f. eks. metyl, etyl eller lignende, hydroksyl som hydrok-syetyl, hydroksypropyl eller lignende, eller alkylen som f. eks. etylen; hvor R2 betegner vannstoff, alkyl eller hydroksyalkyl som nevnt ovenfor, og Z betyr de atomer som er nødvendige for å komplettere en cykloheksadienring, f. eks. 1,5-cykloheksa-dien, alkylcykloheksadien, d. v. s. metyl-cykloheksadien, etylcykloheksadien og lignende, halogencykloheksadien som f. eks. where R' — CH2 is an alicyclic radical, e.g. dehydroabietyl, dihydroabietyl, tetrahydroabietyl or dextropyramyl, where R denotes hydrogen, alkyl such as e.g. methyl, ethyl or the like, hydroxyl such as hydroxyethyl, hydroxypropyl or the like, or the alkylene such as e.g. ethylene; where R2 denotes hydrogen, alkyl or hydroxyalkyl as mentioned above, and Z denotes the atoms necessary to complete a cyclohexadiene ring, e.g. 1,5-cyclohexadiene, alkylcyclohexadiene, i.e. methylcyclohexadiene, ethylcyclohexadiene and the like, halocyclohexadiene such as e.g.

kl<p>rcykloheksadien, bromcykloheksadien og lignende, eller en di- eller polyhydro-naftalinring; hvor = N2 og = O alltid inntar nabostillinger i den samme ring, og hvor n betegner et helt tall som ikke er større enn 2, og n alltid er lik 2 hvis R er alkylen. chlorocyclohexadiene, bromocyclohexadiene and the like, or a di- or polyhydro-naphthalene ring; where = N2 and = O always occupy adjacent positions in the same ring, and where n denotes an integer not greater than 2, and n is always equal to 2 if R is alkylene.

Mange av de ovenfor nevnte forbindelser kan fremstilles ved å la et passende diazooksyd av et aromatisk sulfonylklorid reagere med et egnet alicyklisk amin. Reaksjonsmediumet kan være en hvilken som helst væske som er et tilstrekkelig godt oppløsningsmiddel for utgangsmaterialene til å muliggjøre reaksjon mellom disse og som er tilstrekkelig inert i forhold til sulfonylklorid til å hindre gjensidig reaksjon under de herskende forhold. Som oppløs-ningsmidler foretrekkes isopropylalkohol og dioksan. Many of the above compounds can be prepared by reacting a suitable diazo oxide of an aromatic sulphonyl chloride with a suitable alicyclic amine. The reaction medium can be any liquid which is a sufficiently good solvent for the starting materials to enable reaction between them and which is sufficiently inert in relation to sulfonyl chloride to prevent mutual reaction under the prevailing conditions. The preferred solvents are isopropyl alcohol and dioxane.

De alicykliske aminer som kan anvendes er dehydroabietylamin-, dihydro-abietylamin, tetrahydroabietylamin, dekstropimarylamin, 2-dehydroabietyl-aminoetanol, N-metyldehydroabietylamin, N-etyldehydroabietylamin, N,N'-etylen-didehydroabietylamin og liknende. Disse aminer kan skaffes som sådanne eller i blanding med hverandre, og det kan anvendes såvel de enkelte aminer som blan-dinger av dem. Spesielt fordelaktig er det i handelen forekommende prdoukt «Rosin Amine D» som inneholder ca. 90 pst. dehydroabietylamin. The alicyclic amines which can be used are dehydroabiethylamine, dihydroabiethylamine, tetrahydroabiethylamine, dextropyramylamine, 2-dehydroabiethylaminoethanol, N-methyldehydroabiethylamine, N-ethyldehydroabiethylamine, N,N'-ethylene-didehydroabiethylamine and the like. These amines can be obtained as such or in a mixture with each other, and both the individual amines and mixtures of them can be used. Particularly advantageous is the commercially available product "Rosin Amine D", which contains approx. 90 percent dehydroabiethylamine.

Blant sulfonylklorider der kan anvendes som sådanne er 6-diazo-5(6)-okso-l-naftalensulfonylklorid, som har den føl-gende formel: Among sulfonyl chlorides that can be used as such are 6-diazo-5(6)-oxo-1-naphthalenesulfonyl chloride, which has the following formula:

3 -diazo-4 (3) -okso-1 -naf talinsulf onyl-klorid med følgende formel 3-diazo-4-okso-l,5-sykloheksadien-l-sulfonylklorid med den følgende formel: 3-diazo-4 (3)-oxo-1-naphthalene sulfonyl chloride of the following formula 3-diazo-4-oxo-1,5-cyclohexadiene-1-sulfonyl chloride of the following formula:

Forbindelse kan også som sulfonyl-halvdel inneholde 5,6,7,8-tetrahydro-4-diazo-3- (4) -okso-2-naftalinsulfonyl av formelen: Compound can also contain as sulfonyl moiety 5,6,7,8-tetrahydro-4-diazo-3-(4)-oxo-2-naphthalenesulfonyl of the formula:

3-diazo-4(3)-okso-l,6-naftalindisulfonyl av formelen: 3-klor-5-diazo-6-okso-l,3-sykloheksadien-1-sulfonyl av formelen: 3-diazo-5-metyl-4-okso-l,5-sykloheksa-diensulfonyl av formelen: 3-diazo-6-metyl-4-okso-l,5-sykloheksa-diensulfonyl av formelen: 3-diazo-4(3)-oxo-1,6-naphthalenedisulfonyl of the formula: 3-chloro-5-diazo-6-oxo-1,3-cyclohexadiene-1-sulfonyl of the formula: 3-diazo-5-methyl -4-oxo-1,5-cyclohexadiensulfonyl of the formula: 3-diazo-6-methyl-4-oxo-1,5-cyclohexadiensulfonyl of the formula:

og liknende. | and similar. |

Disse halvdeler kan innføres i det alicykliske amin eksempelvis på den måte som er generelt beskrevet i de tyske patenter nr. 888 204 og 871 668. Hvis det aromatiske sulfonylradikal er monocyklisk kan således den tilsvarende aminohydrok-sulfonsyre omdannes til et benzoksalon-sulfonylklorid, som igjen kan bringes til å reagere med det ønskede alicykliske amin. Benzoksalonringen kan så spaltes ved opp-hetning med alkali, og det resulterende aminohydroksysulfonamid kan omdannes til sammes hydroklorid. Hydrokloridet kan deretter, eventuelt uten først å isoleres, diazoteres og gi det ønskede diazooksyd. These moieties can be introduced into the alicyclic amine, for example, in the manner generally described in German patents no. 888,204 and 871,668. If the aromatic sulfonyl radical is monocyclic, the corresponding aminohydrosulfonic acid can thus be converted into a benzoxalone sulfonyl chloride, which in turn can be reacted with the desired alicyclic amine. The benzoxalone ring can then be cleaved by heating with alkali, and the resulting aminohydroxysulfonamide can be converted to the same hydrochloride. The hydrochloride can then, possibly without first being isolated, be diazotized and give the desired diazo oxide.

I det tilfelle at en halvdel som inneholder to sulfonylgrupper skal innføres, oppnås dette på den måte som er beskrevet i eks. 10 i tysk patent nr. 871 668. In the event that a half containing two sulfonyl groups is to be introduced, this is achieved in the manner described in ex. 10 of German patent no. 871 668.

Oppfinnelsen vil bli illustrert videre ved de følgende eksempler: Eksempel 1: N-dehydroabietyl-6-diazo-5(6)-okso-l- naftalinsulfonamid. The invention will be further illustrated by the following examples: Example 1: N-dehydroabiethyl-6-diazo-5(6)-oxo-1- naphthalene sulfonamide.

Til en omrørt oppløsning av 28,5 g «Rosin Amine D» (laget av Hercules Powder Company) i 160 ml dioksan settes det 28,5 g 6-diazo-5(6)-okso-l-naftalin-sulfonylklorid. Temperaturen steg til 42° C, klor-idet ble oppløst og i løpet av ca. 5 minutter ble det tilsatt 40 ml av en 3N natrium-karbonatoppløsning. Under fortsatt om-røring ble det langsomt tilsatt 300 ml isvann, sammen med podningskrystaller fra et tidligere fremstilt preparat. Den olje som først skilte seg ut stivnet langsomt til små kuler. Etter to timers forløp ble det gule produkt oppsamlet, vasket og tørket under nedsatt trykk. Utbyttet var praktisk talt kvantitativt. Rensing kunne skje ved at stoffet ble oppløst i alkoholisk natrium-hydroksyd, filtrering og felning med vandig ediksyre (sm.p. 115—36° C spaltning) eller enklere ved omkrystallisering fra al-koholer, etylacetat, aceton eller vandig dioksan. To a stirred solution of 28.5 g of "Rosin Amine D" (made by Hercules Powder Company) in 160 ml of dioxane is added 28.5 g of 6-diazo-5(6)-oxo-1-naphthalene-sulfonyl chloride. The temperature rose to 42° C, the chloride was dissolved and within approx. After 5 minutes, 40 ml of a 3N sodium carbonate solution was added. With continued stirring, 300 ml of ice water was slowly added, together with seed crystals from a previously prepared preparation. The oil that first separated slowly solidified into small globules. After two hours, the yellow product was collected, washed and dried under reduced pressure. The yield was practically quantitative. Purification could take place by dissolving the substance in alcoholic sodium hydroxide, filtering and precipitation with aqueous acetic acid (m.p. 115-36° C decomposition) or more simply by recrystallization from alcohols, ethyl acetate, acetone or aqueous dioxane.

Det i eks. III, IV og V anvendte sulfonylklorid ble fremstilt etter en metode som var lik den som er beskrevet i tysk patent nr. 865 410, side 2, linje 98—103. That in e.g. The sulfonyl chloride used in III, IV and V was prepared by a method similar to that described in German Patent No. 865,410, page 2, lines 98-103.
