ABSTRACT:
In manufacturing a photographic support by coating a travelling paper substrate with a polyolefin resin, the adhesion of the resin to the substrate can be markedly improved by subjecting the uncoated paper substrate to an activation treatment on the side to be subsequently coated with the polyolefin resin and exposing the side of the molten polyolefin resin to be brought into contact with said paper substrate to an ozone-containing gas blown against said molten resin. This method leaves behind no adverse effect on the photographic emulsion which is subsequently applied and permits of marked improvement of the productivity at a low cost.
