Claim:
1. An aqueous ink-jet ink comprising an aqueous vehicle, a pigment and a random copolymer as a binder, wherein said random copolymer is derived from the polymerization of a diisocyanate with three or more diols including a first diol and a second diol, wherein said first diol contains one or more hydrophilic stabilizing groups, the number of backbone atoms on the chain between the two hydroxyl groups of said second diol is less than 8, and the mole % of said second diol relative to the total diols is at least 30%, said copolymer has a general structure of Formula I: wherein the terminal isocyanate groups in said copolymer are capped with a capping agent; each Q 1 , Q 2 and Q 3 is independently provided that Q 1 , Q 2 and Q 3 contain at least one Formula II, at least one Formula III and at least one Formula IV groups; each R each R each R each R n, m and p are integers from 1 to 200; said capping agent is R each R each R R each R each R
