ABSTRACT:
Multi-layer sheet materials useful as protective laminates for application to substrates, such as photographic elements, which require the protection of an abrasion-resistant material, are comprised of a strippable carrier, an abrasion-resistant layer which overlies the carrier, a structural interlayer which overlies the abrasion-resistant layer, and an adhesive layer which overlies the structural interlayer. The structural interlayer is very thin in relation to the thickness of the carrier, and is permanently bonded to one surface of the abrasion-resistant layer, whereas the carrier is releasably bonded to the other surface of the abrasion-resistant layer so as to permit it to be stripped away after it has served its purpose. A process for manufacturing the multi-layer sheet material comprises the steps of advancing the carrier in web form through a coating station at which it is coated with a layer of liquid composition that is curable to a solid form; laminating the structural interlayer to the coated surface of the carrier; curing the liquid layer in situ to a solid form to thereby form an abrasion-resistant layer; and applying an adhesive layer over the surface of the structural interlayer.
