  • Method for recording and processing motion picture film soundtrack
    Patent number: 5753402
    Abstract: By processing color motion picture film to yield a dye-only, "silver-less" soundtrack, an antihalation layer containing silver may be incorporated into the film without interfering with the soundtrack signal in the resulting processed film. The process results in good antihalation protection of the print film during exposure, and a simplified processing procedure which does not require special processing of the exposed soundtrack relative to the image area frames.
