Abstract
A photographic printing paper support is described in which a raw paper material is prepared at a neutral pH range using a copolymer-type cationic polyacrylamide in the presence, when required, of an epoxidized higher fatty acid amide, both sides of the raw paper being coated with a polyolefin resin. Based on this production process, the permeation of developing solution into the support at the time of development processing can be sufficiently prevented. Also, wetting on the wire during the manufacture of the support can be improved. With the use of the epoxidized higher fatty acid amide as a sizing agent, the production cost can be reduced significantly.
