Photographische Silberbromidemulsion mit erhöhter EmpfindlichkeitSilver bromide photographic emulsion with increased sensitivity
Die vorliegende Erfindung betrifft ein Verfahren zur Steigerung der Empfindlichkeit photographischer Silberbromidemulsionen durch Zusatz von heterocyclischen Oniunverbindungen mit TMoäthergruppierungen. The present invention relates to a method of increasing the sensitivity of photographic silver bromide emulsions by adding heterocyclic onium compounds with TMoether groups.
Die Empfindlichkeit einer photographischen Emulsion läßt sich auf zweierlei V/eise beeinflussen. Zunächst ist es möglich, bei der sogenannten chemischen Reifung während der Emulsionsheretellung durch verlängerte Reifzeit oder durch Zusatz geeigneter Substanzen, wie Thiosulfat oder auch anderer, meist schwefelhaltiger Präparate, die Empfindlichkeit zu erhöhen. Die andereThe sensitivity of a photographic emulsion can be influenced in two ways. First of all, it is possible at the so-called chemical ripening during emulsion production by extending the ripening time or by adding suitable substances such as thiosulphate or other, mostly sulfur-containing substances Preparations to increase sensitivity. The other

Art der Empfindlichkeitserhöhung einer photographischen Emulsion besteht im Zusatz sogenannter Entv/icklungsbeschleuniger oder chemischer Sensibilisatoren. Diese werden üblicherweise der bereits fertig gereiften Emulsion zugefügt.The way in which the sensitivity of a photographic emulsion is increased is the addition of so-called development accelerators or chemical sensitizers. These will usually be the already ready-ripened emulsion added.
Als Entv/icklungsbeschleuniger wurden dabei z. B. Verbindungen mit Oniumstruktur (wie etwa quaternäre Ammonium-, Phosphonium- und ternäre Sulfoniumsalze) sowie sehr häufig auch Polyalkylenoxide und Polyalkylenoxidderivate beschrieben. Gerade bei der zuletztgenannten Stoffklasse sind viele Versuche gemacht worden,um die erzielten Empfindlichkeitsgewinne durch Abwandlung der Derivate oder durch kombinierte Anwendung zusammen mit anderen Verbindungen zu erhöhen. Alle diese Verbindungen erfüllen jedoch nicht die von der Praxis geforderten Eigenschaften in vollem ; Maße, sei es, daß die Empfindlichkeitssteigerung unbefriedigend ist oder daß der mit der Sensibilisierung verbundene Schleier eine Anwendung verhindert.As a development accelerator, z. B. Compounds with an onium structure (such as quaternary ammonium, phosphonium and ternary sulfonium salts) and very often also polyalkylene oxides and polyalkylene oxide derivatives are described. With the last-mentioned class of substances in particular, many attempts have been made to increase the sensitivity gains achieved by modifying the derivatives or by combining them with other compounds. However, all of these compounds do not fully meet the properties required in practice ; To some extent, be it that the increase in sensitivity is unsatisfactory or that the fog associated with the sensitization prevents use.
Der Erfindung liegt die Aufgabe zugrunde, neue chemische Sensibilisatoren zu finden, die die obigen Nachteile nicht besitzen und mit deren Hilfe eine Steigerung der Empfindlichkeit photographischer Halogensilberemulsionen ohne Verursachung einer unerwünschten Schleierbildung möglich wird. The invention is based on the object of finding new chemical sensitizers which do not have the above disadvantages and with the aid of which it is possible to increase the sensitivity of photographic silver halide emulsions without causing undesirable fogging .

Es wurde nun gefunden, daß man bei Silberbroinidemulsionen besonders hohe Empfindliehkeitsgewinne bei relativ geringem Schleieranstieg er reichen kann, wenn man die Entwicklung in Gegenwart von 1,4-Thiazanen der folgenden Formel ausführt:It has now been found that with silver broinide emulsions in particular high gains in sensitivity with a relatively low increase in haze can be enough if you develop in the presence of 1,4-thiazanes of the following formula:

R« = (l) Wasserstoff,(2 ) geradkettiges oder verzweigtes Alkyl mit bis zu 12. C-Atomen, vorzugsweise mit bis zu 5 C-Atomen, wobei die Alkylreste substituiert sein können mit Phenyl, Hydroxyl, Cyano, Carboxyl, verestertes Carboxyl oder Alkoxy, (3) Aryl, insbesondere Phenyl, wobei die Phenylreste ebenfalls substituiert sein können, (4) Acyl, insbesondere Acyl, das sich ableitet von aliphatischen Carbonsäuren mit vorzugs weise bis zu 5 C-Atomen, (5) Carbamyl, wobei die Amidgruppe substituiert sein kann mit Alkyl mit vorzugsweise bis zu 5 C-Atomen, Aralkyl wie Benzyl oder Aryl, insbesondere Phenyl und (6) eine Aminogruppe, wobei die Wasserstoffatome der Aminogruppe substituiert sein können mit Alkyl, vorzugsweise mit bis zu 5 C-Atomen, Aryl, insbesondere Phenyl oder Acylgruppen, inabesondere die der obenangegebenen Art; die Aminogruppe kann außerdem substituiert sein mit Carbanylgruppen, wobei diese wiederum alkyliert oder phenyliert sein können.R «= (1) hydrogen, (2) straight-chain or branched alkyl with up to 12 carbon atoms, preferably with up to 5 carbon atoms, it being possible for the alkyl radicals to be substituted by phenyl, Hydroxyl, cyano, carboxyl, esterified carboxyl or alkoxy, (3) aryl, especially phenyl, the phenyl radicals also can be substituted, (4) acyl, in particular acyl, which is derived from aliphatic carboxylic acids with preference wise up to 5 carbon atoms, (5) carbamyl, where the amide group can be substituted with alkyl with preferably up to 5 C atoms, aralkyl such as benzyl or aryl, in particular phenyl and (6) an amino group, the hydrogen atoms being the Amino groups can be substituted with alkyl, preferably with up to 5 carbon atoms, aryl, in particular phenyl or acyl groups, in particular those of the kind specified above; the amino group can also be substituted with carbanyl groups, which in turn can be alkylated or phenylated.

Soweit das Stickstoffatom des Morpholinringes in der Lage ist, einfache Salze bzw. quaternäre Ammoniumsalze zu bilden, können selbstverständlich auch diese in der erfindungsgemäßen Weise eingesetzt werden. Als quaternäre Gruppen sind Alkyl mit bis zu 12 C-Atomen, vorzugsweise mit bis zu 5 C-Atomen geeignet, wobei diese Alkylgruppen substituiert sein können, z. B. mit Phenyl wie in den Benzylphenyläthylgruppen.As far as the nitrogen atom of the morpholine ring is able to To form simple salts or quaternary ammonium salts, these can of course also be formed in the manner according to the invention can be used. Suitable quaternary groups are alkyl with up to 12 carbon atoms, preferably with up to 5 carbon atoms, where these alkyl groups may be substituted, e.g. B. with phenyl as in the benzylphenylethyl groups.
Dabei können beliebige Anionen auftreten, z. B. Halogen, Halogenide, Perchlorate und ähnliche. Eine Quaternierung des Stickstoffatoms des Morpholinringes ist bekanntlich dann nicht möglich, wenn die basischen Eigenschaften des Stickstoffes durch negative Substituenten unterdrückt sind. Dies trifft z. B. zu, wenn R1 Phenyl, Carbamyl oder Acyl bedeutet.Any anions can occur, e.g. B. halogen, halides, perchlorates and the like. As is known, quaternization of the nitrogen atom of the morpholine ring is not possible if the basic properties of the nitrogen are suppressed by negative substituents. This applies e.g. B. to when R 1 is phenyl, carbamyl or acyl.
