Abstract (en)

[origin: EP0344335A1] A photographic base material of plastic-coated paper, which shows improved mottle behaviour, is described. This can be produced by a pretreatment having an oxidising action with subsequent application of an adhesion layer which predominantly consists of gelatine and which is subjected to a corona treatment, after it has been dried and before the light-sensitive photographic emulsion is applied.
