Abstract
Viscose Ozaphane, a new type of film with a base of regenerated cellulose sheeting, and having certain advantages for record use, was tested lo determine its comparative stability. Its stability was compared with that of cellulose wilrafe, and also with that of cellulose acetate, which is widely, used for slide-film and which has been found to be a very stable material for preserving records in libraries. The viscose type of film apparently is not suitable for permanent records, hut does appear to have properties to recommend its use for reading-room copies that can be replaced when they become unserviceable. The stability was determined by measuring changes in the chemical and physical properties under accelerated aging. The changes observed were increase in acidify and copper number, and decrease in viscosity, weight, and flexibility.
