Definitions
- some processes have been hitherto employed such as a process to balance the curl of the emulsion layer with a curl of a gelatin layer applied on the other side of the film; a process to apply some layers of certain substances other than gelatin in order to achieve the curling balance corresponding to the swelling or shrinking of the emulsion layer during the developing step; and a process to apply a layer which balances the curl corresponding to the swelling or shrinking of the emulsion layer during development and may be removed during that step.
- FIG. 3 is a graph which shows the relation of the curling value, humidity and times in Example 1.
- FIG. 3 shows that a higher temperature, a higher humidity and a longer blowing time yield a greater effect.
- EXAMPLE 3 Cellulose triacetate was dissolved in a mixture of so]- vents consisting chiefly of methylene chloride. A plasticizer was added to the resulting solution to obtain a dope. The dope, having a concentration of 20.0 wt. was flowed onto the surface of a support. The prepared film was stripped from the surface of the support when 25 wt.% of the solvent remained in the film, and was introduced into a drying chamber.
- EXAMPLE 4 Cellulose triacetatefilm. having a thickness of 140 microns was processed under two conditions,"( 1) 70C and 0.2 Kg steam/Kg dry air, and (2) 150C and 2 Kg steam/Kg dry air, with the time being varied, in the same way shown in Example 1.
- the curling values of the processed films were measured at 23C, and 25,55 and 85% RH (these values being denoted by K K K respectively).
- plastic film is a cellulose ester, polyvinyl chloride, polystyrene or polyethylene terephthalate film.
- cellulose ester is cellulose nitrate, cellulose acetate, cellulose propionate, cellulose butyrate or a mixture theseof.
