Abstract (en)

[origin: EP0754970A1] A method is provided for applying any hydrophilic colloid layer on a naked glass support comprising the steps of (i) wetting a naked glass support, with a polar solvent comprising more than 1 % water, (ii) applying the hydrophilic colloid layer, provided on a temporary support, onto the wet glass support, so that the hydrophilic colloid layer is in direct contact with the wetted glass and (iii) stripping the temporary support away. It is preferred that the wetting solution comprises an organic silicon compound. The method is especially suited for applying photographic layers on a naked glass support. By using this method no special adhesive layer is needed and all photographic properties are kept unimpaired.
