deterioration of film-based negatives Recent research indicates that all cellulosic plastic materials have essentially the same deterioration mechanisms. In other words, nitrate, diacetate, and triacetate materials will deteriorate in much the same way and at essentially the same rate (Reilly, 1993). F. Gugumus (1989) examined the oven stability of a polypropylene film for up to about 1.5 years between 40 and about 105°C, and the apparent activation energy in the Arrhenius plot was clearly variable with respect to temperature with a diminishing trend toward lower temperatures. While celluloid film was standard for 35mm theatrical productions until around 1950, motion-picture film for amateur use, such as 16mm and 8mm film, were on acetate "safety base", at least in the US. Celluloid is useful for producing cheaper jewellery, jewellery boxes, hair accessories and many items that would earlier have been manufactured from ivory, horn or other expensive animal products.
