MOLECULAR GRAFTING OF CARBOXYL REACTIVE HARDENERS TO ENERGETICALLY TREATED POLYESTERS TO PROMOTE ADHESION OF LAYERS |
摘要 |
The present invention comprises a polyester film support in which the surface has been subjected to an energetic treatment to produce carboxyl groups on the polyester surface. The treated surface is then coated with a dilute solution of carboxyl reactive hardener and solvent (e.g., water) or a blend of carboxyl reactive hardener and gelatin and solvent (e.g., water). After drying the hardener or hardener/gelatin coated support, a photographic emulsion is coated on the surface. The resulting film element has excellent adhesion of the photographic emulsion after photoprocessing. Furthermore, the support coated with hardener/gelatin blend is safer to coat and handle than previously known methodsinvolving grafting of hardener directly to the support.
