Behavior of Gelatin in the Processing of Motion Picture Film

The mechanics of motion picture film are largely determined by its make-up as a layer of strongly water-absorbent colloid secured to one of slightly water-absorbent colloid. Naturally the boundary between these relatively wet and dry states is subject to considerable stress, and it sometimes happens that the union between them does not prove indissoluble. I propose to describe in the following, in a rather general way, some of the peculiarities of gelatin in the matter of swelling and shrinking, especially as affected by the solutions and conditions used in photographic processing.
