A method of making a photographic support comprising electron bombarding a layer of hardened gelatine carried by a supoort material to lower the contact angle of the gelatine surface to less than 75 degrees. The support may be cellulose acetate, polyethylene terephthalate, polycarbonate, metal (e.g. aluminium) and glass. The gelatine coating may be hardened with formaldehyde or chromic chloride and may contain pigments and dyes. The treated gelatine coating may be further coated with an aqueous photographic emulsion.ALSO:A method of making a photographic support comprising electron bombarding a layer of hardened gelatine carried by a support material to lower the contact angle of the gelatine surface to less than 75 DEG .
