Abstract (en)
[origin: US4808267A] A waterproof photographic paper support, which is coated with a polyolefin resin, is provided. The paper itself is formed from a particular paper pulp composition which contains fatty acids and/or fatty acid salts and an aluminum salt, as well as, if necessary, alkylketenedimer. Such paper pulp concentration contains, furthermore, anionic and cationic polyacrylamides in the ratio of 40:60 to 60:40, as well as an epoxidized fatty acid amide. The acrylic acid content of the anionic polyacrylamide amounts to between about 5% and 20%.
