Substituted pyrazolo[3, 2-c]-s-triazole photographic couplers and photographic materials and processes employing them |
摘要 |
Pyrazolo[3,2-c]-s-triazole dye-forming couplers containing in the 6-position a substituted or unsubstituted tertiary alkyl group and in the 3-position a substituted or unsubstituted aryl group in photographic materials and processes provide dyes of improved light stability. These couplers are particularly useful in combination with alkoxybenzene dye image stabilizers.
