ABRASION-RESISTANT INK COMPOSITIONS AND METHODS OF USE

摘要

This invention relates to ink compositions that include a stable nonpolyethylene-containing aqueous dispersion of pigment and particles of a urethane polymer. Preferably the composition further includes a cross-linker capable of cross-linking the urethane polymer. The compositions are useful for printing on flexible or elastomeric substrates. These ink compositions demonstrate increased durability, in particular abrasion resistance, abrasion resistance during stretch and water resistance.
