Abstract
Aus DIR-Kupplern der Formel I werden bei Farbentwicklung
hochwirksame Silberhalogenidentwicklungsinhibitoren
freigesezt. Bei Verwendung solcher DIR-Kuppler in
farbfotografischen Silberhalogenidmaterialien werden
hohe Kanteneffekte und hohe Interimageeffekte erhielt.
A-(TIME)n-Z I
In Formel I bedeuten
A den Rest eines Kupplers, der unter den Bedingungen
der fotografischen Entwicklung mit dem Oxidations
produkt eines Silberhalogenidentwicklungsmittels
kuppelt und dabei den Rest der Formel
-(TIME)n-Z
freisetzt;
TIME ein Bindeglied, das bei Reaktion des Kupplers mit
dem Oxidationsprodukt eines Silberhalogenident
wicklungsmittels zusammen mit dem daran gebundenen
Rest Z (einem Triazolring) freigesetzt wird und
seinerseits unter den Entwicklungsbedingungen den
Rest Z verzögert freisetzt;
n 0 oder 1;
Z einen Triazolrest einer der Formeln
R¹ Alkylthio;
R² H, Alkyl, Alkylthio, Aryl oder eine heterocyclische
Gruppe, wobei mindestens einer der Reste R¹ und R²
im Abstand von 2 bis 4 Atomen vom Triazolring eine
in wäßrigem Alkali verseifbare Gruppe -CO-OR³,
-O-CO-OR³ oder -O-CO-R³ enthält;
R³ Alkyl, Cycloalkyl oder Aryl.
Highly effective silver halide development inhibitors are released from DIR couplers of the formula I during color development. When using such DIR couplers in color photographic silver halide materials, high edge effects and high interimage effects are obtained.
A- (TIME) n -Z I
In formula I mean
A is the rest of a coupler which couples under the conditions of photographic development with the oxidation product of a silver halide developing agent and thereby the rest of the formula
- (TIME) n- Z
releases;
TIME is a link which, when the coupler reacts with the oxidation product of a silver halide developing agent, is released together with the residue Z (a triazole ring) attached to it and in turn releases the residue Z with a delay under the development conditions;
n 0 or 1;
Z is a triazole residue of one of the formulas R1 alkylthio;
R² H, alkyl, alkylthio, aryl or a heterocyclic group, at least one of the radicals R¹ and R² at a distance of 2 to 4 atoms from the triazole ring a group saponifiable in aqueous alkali -CO-OR³, -O-CO-OR³ or -O Contains -CO-R³;
R³ is alkyl, cycloalkyl or aryl.
