ABSTRACT:
Photographic coupler compositions comprise a magenta dye-forming coupler and an alcohol in an amount sufficient to increase the activity of the dye-forming coupler. The alcohol is of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of (a) unsubstituted alkyl and alkenyl groups, (b) alkyl groups containing one or more substitutents selected from the group consisting of aryl groups, alkenyl groups, halogen atoms, alkoxy groups, alkoxy carbonyl groups and acyloxy groups, (c) unsubstituted aryl groups and (d) aryl groups containing one or more substituents selected from the group consisting of alkyl groups, alkoxy groups, alkoxy carbonyl groups and acyloxy groups; and R.sub.2 and R.sub.3 are individually selected from hydrogen and the group of moieties from which R is selected, provided that the total number of carbon atoms contained in R.sub.1, R.sub.2 and R.sub.3 is at least 10.
