Definitions
- This invention relates' to a photographic film with a compound cellulosic sheet which is particularly adapted for use as a support in photographic film.
- the object of this linvention is to provide a film with a support having the usual qualities demanded by commercial.conditions in the photographic* art, which will also possess a diminished rate of burning, and will be so constituted that the markings due to electrical discharges (commonly called static) are prevented or very greatly minimized.
- Cther objects will hereinafter appeanj
- Ordinary photographic ilm, particularly suclr as is used in motion picture work generally embodies a support'of nitrocellulose. As usually composed, this support has the essential qualities for commercial work.
- the nitrocellulose support 1 carries on each face a cellulose ether layer 2, the sensitive layer 3 being carried on either ether layer 2.
- l may dissolve 100 parts of ethylcellulose in a compound solvent composed of 340 parts of benzol and lfl'Orparts of ethyl alcohol. Some acetone may also be added to promote adhesion, ifdesired, as indicatedin a copending application of Albert F. Sulzer, ⁇ Serial No. L
- a photographic ilm having its sensitive layer carried on a compound lm support, the latter comprising a layer containing nitrocelluloseA coated on bot-h faces with ethyl cellulose.
- a compound support comprising a layer containing a cellulose ester bearing on each face a coatingcontaining a cellulose. ether.
- a compound support comprising a layer containing nitrocellulose coated on each face with a layer containing a cellulose ether.
