Description
Gegenstand des Hauptpatents 1297 001 ist ein Kopiermaterial für die photomechanische Herstellung von Flach- und Of f. e'druckfolien. welches aus einem Schicht träger und einer daraufhaftenden Kopierschicht besteht, die mit Sa!.-;:i der durch saure Konder.:,a:u.i von meuiilsalzfreien Diphen\lamin-4-diazonHimsa!/en mit Formaldehyd gebildeten Diazoverbindungen lichtempfindlich gemacht ist. und in der Kopierschicht je Mol Diazoniumgruppe mehr als 1.5 Mol Phosphorsäure die in freier oder in an die Dia^oniumgruppen gebLiiden>.r Form \orliegt. enthält.The subject of the main patent 1297 001 is a copy material for the photomechanical production of flat and printing foils. which one layer carrier and a copy layer adhering to it, which is marked with Sa! .- ;: i by acidic Konder.:,a:u.i of diphen \ lamin-4-diazon-hemsa! / en free from meuil salts diazo compounds formed with formaldehyde are made photosensitive. and in the copy layer each Moles of diazonium group more than 1.5 moles of phosphoric acid in free or in to the dia ^ onium groups gebLiiden> .r Form \ is present. contains.
Die Erfindung betrifft in Ausgestaltung des Gegenstandes des Hauptpatents ein Kopiermaterial nach Patent I 292 001. Das Kopiermaterial ist dadurch gekennzeichnet, daß der Schichtträger aus Papier besteht und über 4.5 Mol bis zu 30 Mol Phosphorsäure je Mol Dia/oniumgruppen in der Kopierschicht enthalten sind.In an embodiment of the subject matter of the main patent, the invention relates to a copy material Patent I 292 001. The copy material is characterized by that the support consists of paper and about 4.5 moles up to 30 moles of phosphoric acid per mole Dia / onium groups are contained in the copy layer.
Gegenübc einem Material, das in der Kopierschicht keine Phosphorsäure enthält, weist es eine bessere Beständigkeit auf. Bevorzugt ist dabei ein Kopiermaterial mit 6 bis 15 Mol Phosphorsäure je Mol Diazoniumgruppen in der Kopierschicht.Compared to a material that is in the copy layer Does not contain phosphoric acid, it has better resistance on. A copier material with 6 to 15 moles of phosphoric acid per mole of diazonium groups is preferred in the copy layer.
Ein in der USA.-Patentschrift 2 778 735 näher beschriebener Schichtträger aus Papier wird mit einer Lösung beschichtet, die zwei Gewichtsteile eines durch Kondensation von Diphenylamin-4-diazoniumphosphat-2-carbonsäure mit Formaldehyd in Schwefelsäure hergestellten, als Bisulfat abgeschiedenen Kondensationsproduktes und fünf Gewichtsteile S5°oige Phosphorsäure in 100 Volumteilen Wasser enthält. Man erhält so ein gut lagerfähiges Kopiermaterial, das beim Belichten unter einer Vorlage und anschließendem überwischen mit Wasser eine Druckform liefert,A paper support, described in more detail in US Pat. No. 2,778,735, is coated with a solution containing two parts by weight of a condensation product produced by the condensation of diphenylamine-4-diazonium phosphate-2-carboxylic acid with formaldehyde in sulfuric acid and deposited as bisulfate and five parts by weight S5 ° o by weight phosphoric acid in 100 parts by volume of water. The result is a copier material that can be stored well, which, when exposed under an original and then wiped over with water, provides a printing form,
ίο die die Herstellung einer hohen Zahl einwandfreier Drucke erlaubt.ίο the making a high number flawless Prints allowed.
Zur Herstellung des Bisulfates des Kondensaiionsproduktes trägt man nacheinander 15 Gewichisteile Diphenylamin - 4 - diazoniumphosphat - 2 - carbonsäure und 1.33 Gewichtsteile Paraformaldehyd in 2S.4 volumtcik 7S°oige Schwefelsäure ein. Man erwärmt 1.5 Stunden auf 40 C. läßt über Nacht bei Raumtemperatur stehen und rührt in 500 Volumteile lsopropanol ein. Das Gemisch wird 45 Minuten auf 40 C erwärmt.To prepare the Bisulfates of Kondensaiionsproduktes to sequentially transmits 15 Gewichisteile diphenylamine - 4 - diazoniumphosphat - 2 - carboxylic acid and 1:33 parts by weight paraformaldehyde in 2S.4 v olumtcik 7S cent strength sulfuric acid. The mixture is heated to 40 ° C. for 1.5 hours, left to stand at room temperature overnight and stirred into 500 parts by volume of isopropanol. The mixture is heated to 40 ° C. for 45 minutes.
Man saugt die gut filtrierbare Fällung ab. wäscht mit Isopropanol und trocknet das abgetrennte Produkt im Vakuum bei 40 C.The readily filterable precipitate is filtered off with suction. washes with Isopropanol and dry the separated product in vacuo at 40 C.
Fm gleichwertiges Kopiermaterial erhält man bei Verwendung des auf dem gleichen Wege aus Diphenvlamin-4-diazoniumphObphat-2'-carbonsäure hergestellten Bisulfats des Kondensationsproduktcs zur Senstbilisierung des Tragers.Fm equivalent copy material is obtained from Use of the same route from Diphenvlamin-4-diazoniumphobphat-2'-carboxylic acid produced bisulfate of the condensation product for Senstbilization of the porter.
Ein Schichtträger aus Papier, dessen Herstellung in der USA.-Patenschrift 2 778 735 beschrieben ist. wird mit einer Lösung, dio 2.3 Gewichtsteile eines Kondensates, das aus ?-Methoxy-diphenylannn-4-diazoniumchlond und Formildernd in Salzsäure hergestellt und in Form des Chlorid·* abgeschieden wurde, und 11,5 Gewichtsteile S5'?„ige Phosphorsäure in 100 Volumteilen Wasser enthält, beschichtet. Man belichtet unter einer negativen Vorlage und erhält nach überwischen mit Wasser oder verdünnter wäßriger Gummiarabicumlösung eine positive Druckform, von der hohe Auflagen gedruckt werden können. Das auf diesem Wege hergestellte Kopiermaterial ist in unbelichteten! Zustand sehr gut lagerfähig.A substrate made of paper, the manufacture of which is described in U.S. Patent 2,778,735. is with a solution, dio 2.3 parts by weight of a condensate, that from? -Methoxy-diphenylannn-4-diazonium chloride and Forming was produced in hydrochloric acid and deposited in the form of the chloride · *, and 11.5 Parts by weight of S5% phosphoric acid in 100 parts by volume Contains water, coated. It is exposed under a negative original and obtained after wiping over with water or a dilute aqueous gum arabic solution a positive printing form, from the high one Editions can be printed. The copy material produced in this way is in unexposed! Very good storable condition.
Zur Herstellung des benötigten Diazoniumchlorids verfährt man wie folut: 10.45 Gewichtsteile ^-Methoxydiphen\!amin-4-diazcniumchlorid werden mit 1,21 Gewichtst.-'ien Parafornialdehyd gemischt. Man trägt das Gemisch in 20 Volumteile lonzentrierte Salzsäure ein und rührt es dann eine Stunde bei 40 C und zwanzig Stunden bei Raum'emperatur. Das Reaktionsgemisch wird im Vakuum bei 40 C völlig eingedampft. Man erhält an Ausbeute 11 Gewichtsteile eines Gemisches von etwa gleichen Mengen des sauren und des neutralen Chlorids des Kondensationsproduktes.To prepare the required diazonium chloride, the following procedure is followed: 10.45 parts by weight ^ -Methoxydiphen \! Amin-4-diazcniumchlorid are mixed with 1.21 parts by weight of parafornialdehyde. One carries the mixture is poured into 20 parts by volume of ion-centered hydrochloric acid and then stirred at 40 ° C. and 20 ° C. for one hour Hours at room temperature. The reaction mixture is completely evaporated at 40 ° C. in vacuo. Man receives a yield of 11 parts by weight of a mixture of approximately equal amounts of the acidic and the neutral Chloride of the condensation product.
