Colour couplers are part of the chromogenic colour process. The coupler reacts with oxidised developer to form a dye. The colour of the dye depends upon the type of chemical used as the coupler.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
