Removable guidepath for automated guidance vehicles
First Claim
1. A guidepath composition for detection of emitted radiation by automated guidance vehicles comprising an aqueous dispersion of a sensor-detectable amount of a fluorescent or phosphorescent compound and an effective amount of 5% or less by weight of the aqueous dispersion of a binder including a reversibly crosslinked ionomer.

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.
