Description
Platten, Filme, Papiere usw. für photographische Zwecke Es wurde gefunden, daß für photographische Zwecke, wie Platten, Filme, Papiere und ähnliche Materialien, mit Vorteil als Bindemittel und/oder Farbfilter Polymerisate der Acrylsäureester undloder deren Homologe und/oder Analoge verwendbar sind, wobei diese Verbindungen, gegebenenfalls gefärbt, in gelöstem oder dispergiertem Zustand zur Verwendung gelangen und auch andere Bindemittel, beispielsweise Gelatine, mitverwendbar sind, um insbesondere die Aufnahmefähigkeit für Wasser bzw. für lichtempfindliche Verbindungen auf diese Weise beliebig einzustellen.Plates, films, papers, etc. for photographic purposes It has been found that for photographic purposes, such as plates, films, papers and similar materials, polymers of acrylic acid esters are advantageous as binders and / or color filters and / or their homologues and / or analogs can be used, these compounds, optionally colored, dissolved or dispersed for use and other binders, for example gelatin, can also be used, in particular to the ability to absorb water or light-sensitive compounds to it Way to adjust arbitrarily.
Für farbenphotographische Zwecke können polymerisierte Acrylsäureester mit zwei oder mehreren durch Licht nicht veränderlichen organischen Farben in zwei bzw. mehreren Teilen gefärbt werden, worauf diese verschieden gefärbten Teile gemischt und diese Mischung zur Herstellung photographischer Platten, Filme, Papiere usw. zwecks Erzeugung von mehrfarbigem Kopierpapier usw. unter Zusatz weiterer durch Licht veränderlicher Farben oder Substanzen verwendet «-erden.Polymerized acrylic acid esters can be used for color photographic purposes with two or more organic colors in two that cannot be changed by light or several parts are colored, whereupon these differently colored parts are mixed and this mixture for making photographic plates, films, papers, etc. for the purpose of producing multicolored copy paper etc. with the addition of others Light of changing colors or substances is used.
Das Verfahren zur Herstellung der beschriebenen neuen Mittel für photographische Zwecke ist beispielsweise so durchführbar, daß polymerisierte Acrylsäureester in Wasser dispergiert werden, gegebenenfalls unter Ver-@vendung von dispersionsbeschleunigenden Mitteln. Hierauf, evtl. nach vorhergehender Färbung, werden diese Dispersionen nach Zugabe lichtempfindlicher Stoffe als lichtempfindliche Schicht verwendet.The process for the preparation of the described novel photographic agents Purposes can be carried out, for example, that polymerized acrylic acid esters in Water can be dispersed, if appropriate using dispersion-accelerating agents Means. Thereupon, possibly after previous coloring, these dispersions are after Adding photosensitive substances used as a photosensitive layer.
Die Vorzüge der Anwendung von Polymerisaten, insbesondere von Polymeren der Acrylsäureester, gegenüber bekannten Bindemitteln für die lichtempfindlichen Substanzen liegen darin, daß eine erhöhte Sensibilität der Platten, Filme usw., ferner eine erhöhte Wirkung der kurzwelligen Strahlen infolge der größeren Durchlässigkeit der polymeren Acrylsäurecster für solche Strahlen erzielt wird. Letzteres ist besonders für die Photographie mit Quarzobjektiven bei kurzwelligem Ultraviolettlicht von Bedeutung.The advantages of using polymers, especially polymers the acrylic acid ester, compared to known binders for the photosensitive Substances are that an increased sensitivity of the plates, films, etc., furthermore, an increased effect of the short-wave rays due to the greater permeability the polymeric acrylic acid cster for such rays is achieved. The latter is special for photography with quartz lenses in short-wave ultraviolet light from Meaning.
Die Herstellung der geeigneten Polymerisationsprodukte kann in beliebiger Weise geschehen. Beispielsweise läßt man flüssige nionomere Acrylsäureester sich unmittelbar oder in Lösung in geeigneten Lösungsmitteln ohne weiteres polymerisieren, oder aber die Polymerisierung wird durch Erwärmen oder Bestrahlen mit natürlichen oder künstlichen Lichtquellen beschleunigt. Beispiel ioo Teile Acrylsäuremethylester werden mit ioo Teilen Essigester unter lauwarmem Erwärmen auf 6o bis 8o° oder Einwirkung von ultravioletten Strahlen, Betastrahlen usw. einige Stunden polymerisiert.The preparation of the suitable polymerization products can be carried out in any way Way done. For example, liquid nionomeric acrylic acid esters are allowed polymerize directly or in solution in suitable solvents without further ado, or the polymerization is carried out by heating or irradiation with natural or artificial light sources. Example 100 parts of methyl acrylate with 100 parts of ethyl acetate under lukewarm warming to 6o to 8o ° or exposure polymerized by ultraviolet rays, beta rays, etc. for several hours.
Dieser Mischung werden 5 bis io Teile Bromsilber zugesetzt und in bekannter Weise innig gemischt; hierauf erfolgt in üblicher Weise die Weiterverarbeitung durch Auftragung auf Photoschichtträger und Verdunsten der Lösungsmittel.5 to 10 parts of silver bromide are added to this mixture and mixed in as is known, intimately mixed; this is done in the usual way way the further processing by application to photo layer carrier and evaporation of the Solvent.
