摘要: Hydroxyethylated polyethyleneimine is added to jet ink having an anionic dye to prevent whisker forming overnight. To avoid excessive viscosity at start-up, the polyethyleneimine is low molecular weight or a low molecular weight hydroxyethylated amine is combined with high molecular weight polyethyleneimine.
