Abstract: Transferable and extensible film for coating of surfaces, even with high degree of concavity or convexity, to give them new properties like: abrasion resistance, color, hydrophobic property, anti reflection, or other interferential effects. The film has at 25° C. a maximum elongation higher than 70% and preferably higher than 100%. The film has preferably the configuration of an extensible transfer film assembly. The processes for producing the extensible film and the extensible transfer film assembly and applying them to a substrate are herein described.
