In photographic emulsion adhesion to a polyester film base |
摘要 |
Adhesion of a hydrophilic photographic emulsion to a hydrophobic polyester substrate is achieved by providing the substrate with a surface layer containing free carboxy groups and incorporating in the emulsion a cross-linking agent which can cross-link the emulsion and the carboxy containing surface layer. Carbodiimides are a class of cross-linking agents having this capability.
