Atmospheric pressure glow discharge treatment of base material for photographic applications |
| 摘要 |
The present invention is a method for treating a polyester support such as polyethylene naphthalate or polyethylene terephthalate. The treatment is carried out at atmospheric pressure in a gas of helium and optionally nitrogen and/or oxygen. The treatment uses metallic electrodes and an atmospheric glow discharge results when the electrodes are connected to a generator and spaced about 1 to 2 mm apart. The process and apparatus improve adhesion of subsequently coated emulsions on the polyester support at high speeds and relatively low power by selecting a frequency of 40 kHz to 500 kHz.
