ABSTRACT:
The disclosed moldable compositions contain a metal salt which is a coreactant for, preferably, one of the conventional iron/polyhydric phenol image-forming reactions. The metal salt is dissolved in a liquid plasticizer, and the liquid plasticizer is blended with solid waxes to form a solid, substantially non-toxic, non-hygroscopic, moldable waxy material which is non-softening under normal conditions but which can easily be shaped, hot-melt coated, or the like at temperatures above 60.degree. C. The composition is useful for making wax imaging crayons and sheet-like dispensing means for the metal salt imaging chemical.
