A photographic support is produced by heat consolidating paper made wholly of thermoplastic synthetic fibres. The consolidation is carried out in such a way as to produce a homogeneous surface film having a desired surface finish for receiving a photographic coating, a fully bonded but still fibrous layer adjacent the film, and a lightly bonded fibrous layer adjacent the fully bonded fibrous layer. The homogeneous surface film is produced in such a manner that its surface is substantially free of pits. This may be achieved by consolidating the web by heating it on one surface while cooling it on the other surface.
