Abstract

A package of color photographic film exhibiting enhanced storage stability, wherein a strip of film is wound on a spool, and packed in a metallic film magazine which provides light shielding, and then the packed film is hermetically sealed in a moisture proof envelope, not employing a plastic canister. In this package of color photographic film, contained is the color photographic film having a subbing layer between a substrate and a photographic constitution layer, which subbing layer has a specific dry layer thickness and contains gelatin as the main content of a binder.

Claims

exact text as granted — not AI-modified
1 . A package of color photographic film comprising: 
 a color photographic film which is wound onto a spool, and is packed in a metallic film magazine which provides light shielding, and then the packed film is hermetically sealed in a moisture proof envelope,    wherein a subbing layer provided between a substrate and a photographic constitution layer of the color photographic film has a dry layer thickness of 0.05 to 0.30 μm, and comprises a binder containing a gelatin.    
   
   
       2 . The package of color photographic film of  claim 1 , wherein the gelatin contained in the binder for the subbing layer has a magnesium ion content of not more than 500 ppm.  
   
   
       3 . The package of color photographic film of  claim 1 , wherein the moisture proof envelope exhibits a moisture permeability of not more than 20.0 g/m 2 ·24 h (at 40° C.·90% RH), and an oxygen permeability of not more than 2,000 ml/m 2 ·24 h·101 kPa.  
   
   
       4 . The package of color photographic film of  claim 1 , wherein the moisture proof envelope is made of an aluminum evaporated plastic film.  
   
   
       5 . The package of color photographic film of  claim 1 , wherein the substrate of the color photographic film is an acetyl cellulose ester substrate having an acetylation degree of 2.6 to 3.0.  
   
   
       6 . The package of color photographic film of  claim 1 , wherein the color photographic film comprises a substrate, having thereon an anti-halation layer, light sensitive layers and non-light sensitive layers, 
 wherein the anti-halation later is closest to the substrate of photographic constitution layers, and    each of the light sensitive layers of red, green and blue sensitive layers comprises at least two layers.    
   
   
       7 . The package of color photographic film of  claim 1 , wherein the subbing layer comprises a gelatin having a magnesium ion content of 5 to 100 ppm.  
   
   
       8 . The package of color photographic film of  claim 1 , wherein the color photographic film is hermetically sealed, and the packaged film is packed in a paper-board box.
