ABSTRACT:
An x-ray imaging screen is disclosed comprised of a thermoplastic film support having a planar coating surface and a fluorescent layer coated on that surface. The film support includes an integral lip at its outer boundary extending above the planar coating surface and along peripheral edge portions of the fluorescent layer to protect the fluorescent layer from wear and delamination from the film support. After coating the fluorescent layer on the planar surface of a film support in forming the screen, the coated film support is cut to size by locally heating the film support above its softening point. A softened portion of the film support is caused to flow over the peripheral edge of the fluorescent layer to form the integral lip while cooling the softened portion of the film support immobilizes the integral lip along the peripheral edge of the fluorescent layer, thereby providing a lateral protective buffer for the fluorescent layer along its peripheral edge.
