Use | The fourth in the series of developer used to develop color films, usually called CD-4, chemically called 4-(N-Ethyl-N-hydroxyethyl)-2-methylphenylenediamine sulfate. During color development, the oxidation developer reduces the silver atoms in the silver halide crystal and combines with the color coupling to form color dye molecules. Color developer. The film and photography department is used as a high-temperature fast developer for oil-soluble color film |
