Abstract
A pigment-based ink composition for inkjet printing. The ink composition includes at least one dispersive pigment, an aqueous solution medium, and a 2-pyrrolidone compound. The ink composition of the present invention effectively controls the line width of printed images, decreases feathering, and enhances printing quality when used in inkjet printing.
Claims22
A pigment-based ink composition suitable for inkjet printing, comprising:
- at least one dispersive pigment;
- an aqueous solution medium;
- and
- a 2-pyrrolidone compound,
- whereby when the ink composition is inkjet printed onto a recording substrate, feathering is decreased.
