ABSTRACT:
An interpenetrating polymer network (IPN) or semi-interpenetrating polymer network (semi-IPN) comprises a first phase which is continuous and comprises a flexible polymer and a second phase which is a fluorescent or nonfluorescent durable dispersed or continuous phase and comprises a dye and a polymer, wherein the polymer enhances durability of the dye. Such networks are particularly useful in fluorescent traffic signs or safety devices or in pavement marking tape or paint.
