ABSTRACT:
The characteristics of the surface of an article may be modified, e.g., in respect to adhesion, wettability or other physical characteristics, by exposing the surface to an electrical discharge in a mixture of certain gases. The practice of this invention is particularly useful in improving the gelatin adherence characteristics of a photographic film base support.
