Treatment for Rejuvenating and Preserving Motion Picture Film

The paper briefly describes a method of treating positive and negative motion picture film for eliminating abrasions and scratches and improving its elasticity. There are two treatments: (a) the rejuvenation or regeneration process, by means of which worn and damaged negatives and positives are restored to good condition and (b) the impregnation-preservation process, by means of which new negatives and prints are given a longer life in service or in storage. The processes do not involve the use of lacquers or coatings, but depend upon the swelling and contraction of the film and the glazing of the surface in order to resist scratching and accumulation of surface dirt.
