Beschreibung
Zusammenfassung:	An erasable ink composition contains a dispersion of particles of water-insoluble polymer-encapsulated colorant obtained from the emulsion polymerization of at least one emulsion-polymerizable monomer in the presence of colorant. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen. Une composition d'encre effaçable contient une dispersion de particules d'un colorant encapsulé dans un polymère, insoluble dans l'eau, obtenu par polymérisation en émulsion d'au moins un monomère polymérisable en émulsion en présence du colorant. L'encre est prévue pour être utilisée avec n'importe quel type d'instruments de marquage, notamment, un stylo à bille.
