ABSTRACT:
There are described reversal photographic elements containing magenta dye-forming couplers that yield dye images that particularly lend themselves to retouching. The photographic element comprises a pyrazoloazole magenta dye forming coupler having a cleavable ballast group joined to the remainder of the molecule by one or two electrophilic cleavage groups which can be removed with a specialized processing composition after reversal processing.
