Color Developing Agent 1


Color Developing Agent 1 (CD-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.[1] 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.
