Abstract: Shrinkage characteristics of both 35mm and 16mm films manufactured by Eastman Kodak Co. have been evaluated by laboratory measurements and by examination of film in commercial use. Professional 35mm triacetate films (both positive and earlier negative stock) show a low rate of shrinkage with age, reaching a range of about 0.3% in the lengthwise direction in three years and a maximum amount of not more than 0.6% in the lengthwise direction and 0.7% in the widthwise direction on the average over very long periods of time. An improved support for negative films is now being produced which provides a maximum aging shrinkage of not more than 0.3%. This base is being used for both 35mm and 16mm negative stock for black-and-white and color film. 16mm black-and-white positive films show essentially the same shrinkage characteristics as 35mm positive products. Kodachrome 16mm acetate propionate films of current manufacture have low shrinkage characteristics, reaching maximum values of approximately 0.3% in the lengthwise direction and 0.4% in the widthwise direction over long periods of time.
