Abstract: The present invention relates to a combined phosphorescent, retroreflective and fluorescent article comprising a substrate, a phosphorescent layer on at least one side of the substrate and a retroreflective and fluorescent sheet provided over the phosphorescent layer, wherein the retroreflective and fluorescent sheet is configured so that at least 5% of visible area of said one side is phosphorescent.

Abstract: A method of manufacturing a combined photoluminescent and retroreflective sheet material is disclosed. The method comprises the coating of at least part of one side of a sheet of a substrate (3) such as a fabric substrate, with a mixture of an adhesive and a photoluminescent pigment. The mixture preferably comprises between 20% and 70% inclusive of a photoluminescent pigment having a size between 20 microns and 60 microns inclusive. The adhesive is preferably a transparent adhesive. The coated sheet of substrate (7) is then cured prior to the securement of one or more pieces of a retroreflective sheet (9) o one or more predetermined areas of said one side of the sheet of the substrate to form the sheet material such that at least 5% of visible area of said one side of the sheet material is photoluminescent.
