ABSTRACT:
Solid correction compositions useful in the form of a stick for correcting markings. The compositions include an opacifying pigment dispersed in a solid mixture of selected first and second waxes and a compatible film forming polymeric hardening material. The stick is rubbed over the marking to be corrected to deposit an adherent film which obscures the marking and can receive and retain a corrected marking.
