17 IM-0314 TITLE PHOTOGRAPHIC BACKING LAYERS WITH IMPROVED COATING PROPERTIES ABSTRACT OF THE INVENTION An improved process for the preparation of backing layers with improved coating qualities is described. These layers are designed to transmit antistatic properties from antistatic layers coated under the backing layers and provide antihalation or anticurl effects in addition thereto. The process of this invention includes in-line addition of a pre-stabilized crosslinking solution to a gelatino-conductive polymer solution just prior to the coating thereof. Smooth, skip-free coatings are obtained and the solutions are stable and can be maintained for long periods of time. 17
