ABSTRACT:
Floor mats and methods for producing such mats having wear resistant phosphorescent borders that emit light after removal of ambient light so that the mat edges are visible in the event of a power failure in the facility where the mat is used. The mat border may also contain a bright pigment in the border regions and a contrasting pigment in other regions to make the border visually distinctive under normal lighting conditions. The mats may be produced from solid or foamed polyvinyl chloride materials.
