Abstract
An inkjet ink for printing durable outdoor images with an inkjet printer includes an basic pH aqueous ink vehicle comprising water, a soluble base, and at least one water soluble organic solvent; a pigment dispersion; and a polymer comprising base neutralized carboxylic acid groups with a glass transition temperature between 0 and 150° C. and an acid number between 50 and 1000 mg KOH/g dissolved in the vehicle, wherein the carboxylic acid groups are base neutralized; a poly-electrophilic functionalized compound capable of crosslinking the neutralized carboxylic acidic groups on the polymer wherein the ratio of the poly-electrophilic groups on the functionalized compound to carboxylic acid groups on the polymer is 1:1 or less on an equivalent basis and the ink maintains a stable viscosity and pigment particle size distribution for 6 weeks at 60° C.; the water in the ink inhibiting the crosslinking reaction until after the ink is printed and the water is substantially removed from the ink by drying.
