摘要： A paper support material for photographic layers, as well as a process for the manufacture of such a support material, includes coating the paper on at least one side with a polyolefin layer containing a polyalkylene glycol, preferably a polyethylene glycol, a polypropylene glycol, or a copolymer of ethylene oxide and propylene oxide in a quantity between 40 ppm and 1% by weight, relative to the total quantity of the polyolefin. The molecular weight of the polyethylene glycol can be between 100 and 35,000, preferably 400 to 20,000, that of the polypropylene glycol can be between 400 and 10,000, preferably between 2,000 and 4,000, and that of the copolymers of ethylene oxide and propylene oxide can be between 200 and 20,000. In addition to the polyalkylene glycol, the polyolefin layer advantageously contains a fatty acid derivative from the group of soaps and fatty acid amides.
