Abstract
An aqueous guidepath coating composition includes a fluorescent dye, and an acrylic ionomer, and is particularly useful in positional control of and positional detection by stimulated emission-guided Automated Guidance Vehicles (AGV). This coating, used to mark the actual position of the guidance track to be followed by the AGV, affords unexpected improvements over previous guidepath compositions in removal and reapplication characteristics, in post-application durability and in substrate aesthetics.
