Abstract
Abstract Disclosed is a process for preparing an ink composition which comprises treating a dye with a zeolite, followed by admixing the treated dye with an aqueous liquid vehicle to form an ink composition. Alternatively, the process can comprise admixing a dye and an aqueous liquid vehicle to form an ink composition, followed by treating the ink composition with a zeolite. Also disclosed is an ink container comprising (a) an exit opening; (b) an ink storage area; and (c) a zeolite filter situated between the exit opening and the ink storage area. Further disclosed is an ink container comprising (a) an exit opening; (b) an ink storage area; and (c) a zeolite situated within the ink storage area and situated so that it is in contact with ink contained within the ink storage area.
