PHOSPHORESCENT MARKING MATERIAL

摘要

A non-toxic moldable phosphorescent marker (10) has phosphorescent pigment particles (18) that are suspended in a milled mixture (12) of an inert filler (16) and a wax blend base (14). 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.
