Description

Lichtpausmaterial Als durchsichtiges Lich.tpausmaterial hat man schon die verschiedensten mit lichtempfindlichen Stoffen versehenen Träger benutzt. Die bekannten Produkte haben aber teils nur eine sehr ungleichmäßige Transparenz, teils genügen ihre mechanischen Eigenschaften, insbesondere ihre Festigkeit, nicht allen Anforderungen, oder die Maßbeständigkeit ist ungenügend.Blueprint material You already have transparent light tracing material the most varied of supports provided with photosensitive substances are used. the but known products sometimes have only a very uneven transparency, sometimes their mechanical properties, in particular their strength, are not sufficient for all Requirements, or the dimensional stability is insufficient.

Es ist gefunden worden, daß man ein Lichtpausmaterial herstellen kann, welches die erwähnten Nachteile nicht aufweist, wenn man als Träger des lichtempfindlichen Stoffes ein durchsichtiges Fasermaterial, insbesondere Mull, Batist oder ein ähnliches dünnes Gewebe, verwendet, das beiderseitig mit einer Folie aus Cellulosehydrat oder einem wasserquellbaren Cellulosederivat, beispielsweise aus einem Celluloseäther, überzogen ist. Zum Sensibilisieren werden Lösüngeri beliebiger lichtempfindlicher Stoffe verwendet, z. B. Lösungen, die eine Diazoverbindung und eine Kupplungskomponente enthalten. Bei der Herstellung des erwähnten Trägers wird zweckmäßig nur die eine der äußeren Folien mit der lichtempfindlichen Lösung in Berührung gebracht, beispielsweise durch Aufstreichen, und zwar so, daß die Lösung nicht zu tief eindringt. Auf diese Weise wird eine Beeinträchtigung der Festigkeit der Zwischenschicht verhindert und ein leichteres Korrigieren des Materials ermöglicht.It has been found that one can produce blueprint material which does not have the disadvantages mentioned, if the support of the photosensitive Fabric is a transparent fiber material, in particular gauze, batiste or the like thin fabric, used on both sides with a film of cellulose hydrate or a water-swellable cellulose derivative, for example from a cellulose ether, is covered. To sensitize, solvents of any kind become more sensitive to light Substances used, e.g. B. Solutions containing a diazo compound and a coupling component contain. In the production of the carrier mentioned, only one is expedient the outer foils brought into contact with the photosensitive solution, for example by spreading it on so that the solution does not penetrate too deeply. To this This prevents impairment of the strength of the intermediate layer and enables the material to be corrected more easily.

Das neue Lichtpausmaterial zeichnet sich durch eine hohe Festigkeit und gleichmäßige Transparenz aus. Es besitzt außerdem gute Maßbeständigkeit, neigt nicht zum trollen fand läßt sich gut beschriften.The new blueprint material is characterized by its high strength and uniform transparency. It also has good dimensional stability, tends not to be found trolling can be easily labeled.
