Patent

CA 2333187

A marking system that advantageously minimizes messiness during use is disclosed. The marking system comprises a marking composition comprising at least one color precursor in the form of a leuco dye. A marking instrument can be utilized to store the marking composition and/or apply the marking composition to a desired substrate. The substrate is provided with a coating comprising at least one color-triggering developper. Upon application of the leuco dye to the substrate, a chromophore, and hence, color, is formed. If, however, color is inadvertently triggered on an unintended surface, thereby resulting in an unwanted stain, the stain can be readily removed.

L'invention porte sur un système de marqueurs réduisant les salissures comprenant une composition colorante consistant en au moins un précurseur de couleur sous forme d'un colorant leuco, et un marqueur pouvant le stocker et/ou l'appliquer sur un substrat adéquat revêtu d'au moins un développeur suscitant la couleur. Lors de l'application de la composition sur le substrat se forme un chromophore et la couleur apparaît. Par contre si la couleur est involontairement suscitée par exemple sur une surface non agréée, il se produit une tache non souhaitée mais facile à éliminer.
