Abstract
Der in einem farbfotografischen Aufzeichnungsmaterial
bei Verwendung von Pyrazoloazolkupplern auftretende
erhöhte Pupurschleier wird verringert, wenn gleichzeitig
eine Verbindung einer der Formeln II und III verwendet
wird:
worin bedeuten:
R⁴ Alkyl, Alkoxy, Aryl, Amino, Acylamino;
R⁵ Alkyl;
R⁶ Alkyl, Alkoxy, Aryl, eine heterocyclische Gruppe;
R⁷ Alkyl, Aryl, eine heterocyclische Gruppe;
oder R⁵ zusammen mit R⁶ einen Rest zur Vervollständigung
eines 5- oder 6-gliedrigen Ringes;
V -CN, -CF₃, -SO₃H, Alkylsulfonyl, Sulfamoyl,
Acylamino;
W Halogen, Alkyl, Alkoxy;
s eine ganze Zahl von 1 bis 3;
t 0 oder eine ganze Zahl von 1 bis 4, mit der
Maßgabe, daß s + t ≦ 5.
The increased pupil haze that occurs in a color photographic recording material when pyrazoloazole couplers are used is reduced if a compound of one of the formulas II and III is used simultaneously: in which mean:
R⁴ alkyl, alkoxy, aryl, amino, acylamino;
R⁵ alkyl;
R⁶ alkyl, alkoxy, aryl, a heterocyclic group;
R⁷ alkyl, aryl, a heterocyclic group;
or R⁵ together with R⁶ is a radical to complete a 5- or 6-membered ring;
V -CN, -CF₃, -SO₃H, alkylsulfonyl, sulfamoyl, acylamino;
W halogen, alkyl, alkoxy;
s is an integer from 1 to 3;
t 0 or an integer from 1 to 4, with the proviso that s + t ≦ 5.
