The third in the series of color developing agents used in developing color films, commonly known as CD-3, is chemically known as N-[2-[(4-Amino-3-methylphenyl)ethylamino]ethyl]methanesulfonamide Sesquisulfate Monohydrate. 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. CD-3 is used in many processes including VNF-1, ECN-2 and the E-6 process.
