Claim Text:
1. An aqueous ink-jet ink comprising a pigment, an aqueous vehicle and an alternating polyurethane binder comprising a first monomer with a formula of OCN—R 1 —NCO and a second monomer with a formula of HO—R 2 —OH, wherein the isocyanate groups in the first monomer react with the hydroxyl groups in the second monomer during polymerization to produce a polymer of the general structure of Formula I: wherein the terminal isocyanate groups in said polymer is capped with a capping agent; each R each R each R each R R n is an integer from 1 to 200; each m is an integer from 1 to 10; said capping agent is one or more members selected from the group consisting of R each R each R each R wherein all the ranges of carbon contents for substituents are carbon contents of the substituents of the entire molecules including the substituents, provided that when R
