Title:
FILM-FORMING COMPOSITION AND THE METHOD OF MAKING CELLULOSE ESTER FILM
Document Type and Number:
WIPO Patent Application WO1982000033
Kind Code:
A1
Abstract:
Incorporation of a polyethoxylated phosphate ester in a film-forming composition containing a cellulose ester dissolved in a solvent medium has been found to promote stripping of the film from the surface on which it is cast. Such use of polyethoxylated phosphate esters as stripping aids is especially advantageous in the manufacture of cellulose ester film base in the photographic industry.
