Abstract

L'invention concerne des compositions destinées à être utilisées dans des instruments d'écriture et qui peuvent être éliminées après application, par exemple par effaçage. Ces compositions comprennent une résine de base et un colorant dissous dans un solvant. Après application sur un substrat, la composition peut être éliminée après l'application si désiré ou si nécessaire.
