ABSTRACT:
An erasable marking material with a wax-based vehicle having a substantially uniform suspension of filler particles and pigment particles and a method for its manufacture. The wax-based vehicle is composed of a base wax and at least one supplemental wax. The wax-based vehicle has an oil content of up to about 10 percent by weight. The wax-based vehicle and suspended filler particles exhibit anti-settling properties for the suspension of fluorescent particles. The pigment particles impart luminescent properties to the marker. When rubbed across a surface, the marker deposits the wax-based vehicle and fluorescent particles to producing an erasable luminescent mark.
