Beschreibung
Zusammenfassung:	According to one aspect, an ink composition includes a colorant, a polyurethane having a peak average molecular weight range of from about 25,000 g/mol to about 35,000 g/mol, and a solvent. The ink composition has a total solids content of less than about 12% by weight, and a ratio of colorant to polyurethane between about 1 : 1 and 1 :2 by weight. Selon un aspect, cette invention concerne une composition d'encre comprenant un colorant, un polyuréthane ayant une plage de poids moléculaires moyens maximale d'environ 25 000 à environ 35 000 g/mol, et un solvant. La composition d'encre a une teneur totale en solides inférieure à environ 12 % en poids, et un rapport du colorant au polyuréthanne entre environ 1:1 et 1: 2 en poids.
