'''Color Developing Agent 2''' is the second in the series of color developing agents used in developing color films. It is commonly known as '''CD-2''' and is chemically known as '''4-diethylamino-''o''-toluidine''', '''1,4-benzenediamine, N4,N4-diethyl-2-methyl-''', '''N1,N1-diethyl-3-methylbenzene-1,4-diamine''', or '''4-(diethylamino)-2-methylaniline'''.<ref name="CD2"/> 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.
