Abstract: Articles are provided which have fluorescent properties and which are suitable for use in making retroreflective articles such as safety and informational signage. The articles have at least two film layers, each film layer including a colorant dye. The multiple film layer sheeting exhibits excellent resistance to weathering and overall color durability while also providing chromaticity properties dictated by industry standards for a particular coloration. A method of preparing the articles is provided. In a particular application, the articles embody retroreflective properties and are informational for safety signage articles such as pedestrian crossing and school safety fluorescent yellow green signs.

Abstract: A fluorescent retroreflective article comprising a polymer resin comprising poly(1,4-cyclohexanedimethanol-co-ethylene terephthalate) and a fluorescent dye selected from the group consisting of perylene imide and perylene ester dyes, thioxanthene dyes, benzoxanthene dyes, and benzothiazine dyes exhibits good color and fluorescent durability. Said PETG fluorescent resin matrix can be used to enhance daytime visibility of a roadway marker. Such a pavement marker comprises a base member comprising a structure of a light-transmissible fluorescent material, the structure having a top surface and a front edge surface, the base member being configured to provide an air cap beneath the structure. Light incident on the top surface of the fluorescent structure is directed through said structure and emitted through said front edge surface to provide a signal to a driver of an oncoming vehicle.
