  • Process for the improvement of the adhesion of photographic layers to a film web by means of a corona treatment
    Patent number: 4055685
    Abstract: Corona treatment involves the continuous subjection of the film web to a steady alternating current discharge. This treatment is carried out in two consecutive stages, the corona discharge frequency f.sub.1 in the first stage being in the range f.sub.1 = 5 to 100 kHz and the corona discharge frequency f.sub.2 in the second stage being in the range f.sub.2 = 500 to 2000 kHz.
