Abstract: Improved adhesion characteristics in a metal-resin composite laminate are provided by the production of enhanced anodized surface characteristics with a separate one-sided etch for metal coil compositions, that can be used for coils of metal substrates that are incorporated into metal composites, particularly for use in exterior applications having enhanced durability and weather-ability, such as traffic signage and fascia display patterns.

Abstract: A melt transferred imaged coated product and process for decorative simulated wood, metal or stone-like patterns especially useful on treated non-sealed, non-anodized metal-resin composites for interior signage and display, is described. The product exhibits excellent adhesion bonding between the aluminum surface and the transferred-carrier film that contains the dry-ink image that is deposited on the aluminum surface. The aluminum surface is prepared by conventional pre-etching means, coated with a suitable thermosetting resin and then optionally primed with an adhesive prior to melt transfer of the image. The final surface finish coating is protected with an additional transparent adhesive backed polymer film.
