ABSTRACT:
A non-toxic moldable phosphorescent marker has phosphorescent pigment particles that are suspended in a milled mixture of an inert filler and a wax blend base. The phosphorescent pigment particles, which impart luminescent properties to the marker, are excited by light. The composition of the marker is such that it leaves a strip of phosphorescent marking material on a surface against which the marker is rubbed. The deposited material contains the suspended phosphorescent particles, which luminesces when excited by light.
