Abstract
A pigmented ink composition for use in jet printing formulated of an aqueous or water-alcohol solvent system, a highly water dispersible white pigment limited to a particle size of less than 5 microns, a water dispersible resinous binder, a basic compound for maintaining a pH within the range of 7.5 to 9.5, and a plasticizer, and which may include in addition a coalescent agent and organic dye components for imparting color to the pigment.
Claims24
A water base jet printing ink composition for printing on black, dark, or highly colored substrates, the essential components of the water based jet printing ink consisting essentially of
- (1) a highly water dispersible white inorganic pigment having a particle size less than 5 microns,
- (2) a water dispersible thermoplastic acrylic resin,
- (3) a solvent selected from the group consisting of low boiling alcohol and water-alcohol mixture,
- (4) a basic compound dissolved in the solvent for adjustment of the pH to within the range of 7.5-9.5,
- (5) a plasticizer which imparts water resistance and abrasion resistance to the formed ink image, and
- (6) water.
