Color Developing Agent 1
Color Developing Agent 1 is the first in the series of color developing agents used in developing color films. It is the organic compound N,N-diethyl-1,4-benzenediamine, which is usually in the form of the monohydrochloride salt. In color development, after reducing a silver atom in a silver halide crystal, the oxidized developing agent combines with a color coupler to form a color dye molecule.
