Abstract
A method of making resin coated photographic paper which comprises providing a paper base, subjecting the paper base to a flame treatment and a corona discharge treatment, providing a polyolefin melt curtain, treating the polyolefin resin melt curtain with a mixture of ozone and air and bringing the paper base in contact with the polyolefin melt curtain to provide a uniform layer of polyolefin resin on the paper base.
