Description

Verfahren zur Herstellung lichtempfindlicher Schichten mittels Diazoverbindungen und Azofarbstoffkomponenten Durch die Patentschriften 386 433, 386 434 und 422 972 ist gezeigt worden, daß man durch gemeinsames Aufbringen von haltbaren Diazoverbindungen mit Azofarbstoffkomponenten praktisch wertvolle lichtempfindliche Schichten erzielen kann. Diese Verfahren. @ermöglichen es, alle Farbnuancen zu erzielen. Jedoch sind die Farbtöne für gewisse Zwecke nicht genügend neutral. Sie erscheinen zum größten Teil, z. B. in der Durchsicht auf transparentem Material, zu prellfarbig.Process for the production of photosensitive layers by means of diazo compounds and azo dye components By patents 386,433, 386,434 and 422,972 it has been shown that co-application of durable diazo compounds achieve practically valuable photosensitive layers with azo dye components can. These procedures. @ make it possible to achieve all color nuances. However, are the color tones are not sufficiently neutral for certain purposes. They appear to be the greatest Part, e.g. B. when looking through transparent material, too bounce-colored.

Es sind auch schon Lichtpauspapiere im Handel gewesen, die Phloroglucin und Resorcin und eine Diazoverbindung enthalten haben.There have also been tracing papers on the market, the phloroglucin and resorcinol and a diazo compound.

Es ist nun gefunden worden, daß man auch auf transparenten Trägern, wie z. B. Filmen, neutrale Nuancen erzielen kann; wenn man als lichtempfindliche Schicht Gemische von wenigstens zwei Azofarbstoffkomponenten zusammen mit Diazoverbindungen verwendet. Haben die Azofarbstoffkomponenten gleiche Kupplungsgeschwindigkeit, so lassen sich hierbei die verschiedensten Mischtöne unter vollkommener Nuancengleichheit auch in den Halbtönen erzielen. Kuppeln. sie verschieden schnell, so entstehen je nach der Stärke der Lichteinwixkung Farbkontraste, die z. B. in der Photographie willkommen sind. Dieselben oder ganz ähnliche Effekte kann man erzielen, wenn man außerdem Gemische von noch zwei oder mehreren Dia,zoverbi;ndungen verwendet, wobei als weitere Variationsmöglichkeit außer der verschiedenen Kupplungsgeschwindigkeit noch die verschiedene Lichtempfindlichkeit der Diazoverbindungen in Betracht kommt.It has now been found that even on transparent substrates, such as B. films, can achieve neutral nuances; when viewed as photosensitive Layer Mixtures of at least two azo dye components together with diazo compounds used. If the azo dye components have the same coupling rate, then so The most varied of mixed tones can be created with perfect nuance equality also achieve in the semitones. Couple. they come into being at different speeds according to the strength of the Lichteinwixkung color contrasts that z. B. in photography are welcome. The same or very similar effects can be achieved if you in addition, mixtures of two or more slide compounds are used, with as a further possibility of variation besides the different coupling speed nor the different photosensitivity of the diazo compounds.

Es war überraschend, daß man auf diese Weise auch auf transparenten Unterlagen Bilder von neutralem Ton ,erhält, da die transparenten Filme mit undurclhsichtigen Unterlagen, wie z. B. Papier, nicht gleichzusetzen sind. Denn bei undurchsichtigen Unterlagen ist der Farbton in der Hauptsache von dem auffallenden Licht abhängig, das keinen so großen Einfluß auf die Nuance hat, während bei transparenten Filmen das durchscheinende Licht die Nuance der erhaltenen Färbung erheblich beeinflußt, so daß im allgemeinen, wie auch bei den früheren Verfahren, die Farbtöne, die auf undurchsichtigem Material neutral erscheinen, auf transparentem Material in der Durchsicht prellfarbig und daher praktisch nicht brauchbar sind. Es war in keiner Weise zu erwarten, daß dieser Nachteil durch. die Verwendung eines Gemisches von wenigstens zwei Azofarbstoffkomponenten zusammen mit Diazoverbindungen vermieden werden konnte. Den lichtempfindlichen Stoffen: können, wie in der Diäzotypie üblich, die verschieden- sten Stoffe, z. B. Säuren, Salze, Stabilisato- ren, einverleibt werden. Beispiel Eine Auflösung von 12,5 Teilen 3-Me- thyl-q.-monoäthylamdobenzol-1-rhazaniumbor= fluorid, 2,4 Teilen salzsaures Salz des 5-Di- methylamido-l-naphthols, 16Teilen 1,8-Amido,- naphtho1-3 # 6-disulfosaures Natron (H-Säure) werden in looo Volumenteilen Wasser ge- löst. Tränkt man mit dieser Lösung einen Cellulosefilm bzw. einen gelatinierten Cellu- loidfilm, so erhält man nach der Belichtung unter einem.,Positiv und Entwicklung in gasförmigem Ammoniak eine braunschwarze Kopie, deren Halbtöne vollkommen. in der Nuance mit den Tiefen übereinstimmen.It was surprising that in this way images of a neutral tone can also be obtained on transparent substrates, since the transparent films with opaque substrates, such as e.g. B. paper, are not to be equated. In the case of opaque documents, the color tone is mainly dependent on the incident light, which does not have such a great influence on the nuance, while in the case of transparent films the light shining through significantly influences the nuance of the coloration obtained, so that in general, as with the earlier processes, the color tones that appear neutral on opaque material, bounce-colored on transparent material when viewed through and are therefore practically unusable. It was in no way to be expected that this disadvantage would result. the use of a mixture of at least two azo dye components together with diazo compounds could be avoided. The light-sensitive substances: can, as is usual in the diacotype, the different most substances, e.g. B. acids, salts, stabilizers ren, to be incorporated. example A resolution of 12.5 parts 3-meter ethyl-q.-monoethylamdobenzene-1-rhazanium boron = fluoride, 2.4 parts of the hydrochloric acid salt of 5-di- methylamido-l-naphthols, 16 parts 1,8-amido, - naphtho1-3 # 6-disulfonic sodium (H-acid) are poured into looo parts by volume of water solves. Soak one with this solution Cellulose film or a gelatinized cellulose loid film, so obtained after exposure under one., positive and development in gaseous ammonia a brownish-black copy, its half-tones perfect. coincide in nuance with the depths.
