ABSTRACT:
Sparingly-soluble alcohols, such as benzyl alcohol, which function to enhance photographic coupling efficiency are incorporated in photographic color developing solutions by the use of solid water-soluble alcohol-precursor compounds. The solid precursor compounds, which can be advantageously utilized as components of an all-solid photographic processing kit, comprise a solubilizing group which is cleaved by the alkaline environment of the color developing solution to form the sparingly-soluble alcohol. Examples of such solid precursor compounds which are especially advantageous in the preparation of color developing solutions are the alkali metal monobenzylcarbonates and the alkali metal monobenzylsulfites.
