    Check (for instance) in

    http://www.sunspotphoto.com/film/color.html (simple)

    http://www.photo.net/photo/orange-negative-mask (short, but technical)

    http://www.infoclub.com.np/science/hsw/film.htm (long, explains everything)

    Very shortly the answer to your question is

    The orange mask comes from the film ;-). It was put there by the manufacturer
    to correct (or to make it easier to correct) the imperfections of the dyes in
    the film.
