ABSTRACT:
A solid marking composition that is erasable from both porous and non-porous marking susbtrates. The solid erasable marking composition comprises (a) an emulsion, the emulsion comprising a discontinuous polymeric phase and a continuous aqueous phase, the emulsion being characterized by its ability to be transformed, upon being contacted with the surface of a porous or non-porous marking substrate, from a first state in which the emulsion is stable to a second state in which the emulsion is unstable and the discontinuous polymeric phase rapidly agglomerates to form a deposit on the surface of the marking substrate with low adhesion thereto; (b) a colorant, the colorant being characterized by its association with the deposit when the emulsion is transformed into the second state; and (c) a shape-giving gel-forming agent, the shape-giving gel-forming agent being a salt of an aliphatic carboxylic acid having from 8 to 36 carbon atoms.
