Abstract

La invención se refiere a una composición de tinta borrable que comprende una dispersión de partículas de colorante encapsulado en polímero insoluble enagua que se obtiene mediante polimerización bajo condiciones de polimerización en emulsión de por lo menos un monómero polimerizable en emulsión en presenciade colorante, siendo la composición de tinta borrable luego de ser aplicada sobre un substrato y secarse sobre el mismo (1) suficientemente adherente alsubstrato para resistir su desprendimiento desde el mismo y (2) substancialmente borrable. La invención se refiere además a un instrumentomarcador que contiene dicha composición de tinta borrable tal como un bolígrafo.The invention relates to an erasable ink composition comprising a dispersion of dye particles encapsulated in insoluble polymer in water which is obtained by polymerization under emulsion polymerization conditions of at least one emulsion polymerizable monomer in the presence of dye, the composition being of erasable ink after being applied to a substrate and drying on it (1) sufficiently adherent to the substrate to resist its detachment from it and (2) substantially erasable. The invention further relates to an instrument marker containing such an erasable ink composition such as a ballpoint pen.
