Description

EMI1.1
Die Erfindung betrifft eine farbenemplindliche photographische Masse von andersartiger oder grösserer Farbenempfindlichkeit als die bisher bekannten Massen.
EMI1.2
eines Farbstoffes der Auramin- bzw. der Iminodiphenylklasse (d. h. S@bstit@tionsderviate von Benzo- phenonin@d) beschrieben.
EMI1.3
von dem erwünschten Effekt abhängig. So wird beispielsweise mit Pinacyanol erhöhte Empfindlichkeit für Rot und Griin erhalten nnd gleichzeitig eine neuartige Empfindlichkeit fur tiefes Rot erzielt. welche beiAnwendungvonPinaeyanolalleinnichterreichbarist.
EMI1.4
Bestandteil wirksam zu sein.
Bei dem Badeverfahren sind die üblichen Abänderungen, welche im Ersatz von etwas Wasser durch Alkohol und dem Zusatz von etwas Ammoniak bestehen, anwendbar.
Die Verwendung von Farbstoffen der Isocyaminklasse für farbenempfindliche photographische Massen ist bekannt, ebenso auch die Verwendung von Auramin als Zusatz für orthochromatische photographisehe Emulsionen, zwecks Herstellung einer selbst schirmenden orthochromatischen Platte durch Verringerung der Empfindlichkeit gegen blaues Licht.
Wenn zwei Farbstoffe gleichzeitig verwendet werden. so ist der gewöhnliche Effekt der, dass eine Platte mit beiden Farbstoffen entsprechende Eigenschaften erhalten wird, obgleich häufig der Effekt des einen oder anderen merklich verringert wird. Gemäss vorliegender Erfindung aber wird durch die Verbindungen von Auramin und Pinacyanol und anderen Verbindungen dieser beiden Klassen die Art der Empfindlichkeit geändert und verbessert. Diese Empfindlichkeit ist jedenfalls nicht solcher Art, wie sie von vornherein erwartet werden konnt und gewöhnlich beträchtlich grösser als die Summe der Effekte

EMI1.1
The invention relates to a color-sensitive photographic composition of a different type or greater color sensitivity than the compositions previously known.
EMI1.2
of a dye of the auramine or iminodiphenyl class (i.e. S @ bstit @ tion derivatives of benzophenonine @ d).
EMI1.3
depending on the desired effect. For example, with pinacyanol, increased sensitivity for red and green is obtained and at the same time a new type of sensitivity for deep red is achieved. which is unreachable when using pinaeyanol alone.
EMI1.4
Ingredient to be effective.
The usual modifications, which consist of replacing some water with alcohol and adding some ammonia, are applicable to the bathing process.
The use of dyes of the isocyanate class for color-sensitive photographic compositions is known, as is the use of auramine as an additive for orthochromatic photographic emulsions for the purpose of producing a self-shielding orthochromatic plate by reducing the sensitivity to blue light.
When two dyes are used at the same time. thus the usual effect is that a plate is obtained with properties corresponding to both dyes, although often the effect of one or the other is markedly reduced. According to the present invention, however, the type of sensitivity is changed and improved by the compounds of auramine and pinacyanol and other compounds of these two classes. In any case, this sensitivity is not of the kind that could be expected from the outset, and is usually considerably greater than the sum of the effects
