1. An inkjet printer containing an aqueous inkjet ink, comprising:
a) at least 50% by weight water; b) from 0.1% to 3% by weight, in toto, of dispersed colored pigment exhibiting a median volume weighted 50th percentile particle size of less than 0.11 microns, wherein said dispersed pigment is a surfactant dispersed, self-dispersed, or encapsulating-dispersant dispersed pigment; c) from 0.1% to 4% by weight of a compound I represented by the following Structure (I): wherein R4 is chosen from the group consisting of —H, —C3, —C2H5, —C3H7, and —CH2O(CH2CHR5O)x4H;
1) provided when R4 is —H, —CH3, —C2H5, or —C3H7, each of R1, R2 and R3 are independently hydrogen or methyl, b is 0 or 1; x1, x2 and x3 are each equal to at least 1, and the sum of x1, x2 and x3 is 3 to 21, and2) provided when R4 is —CH2O(CH2CHR5O)x4H, each of R1, R2, R3 and R5 is independently hydrogen or methyl; b is 0 or 1 and the sum x1, x2, x3, and x4 is from 3 to 28; d) from 0.05% to 3% by weight of a polyurethane latex binder; e) optionally, a water soluble polyacrylate polymer in an amount less than 3% by weight; f) provided that the sum of the polyurethane latex binder and any water soluble polyacrylate polymer is not more than 3% by weight; and g) further provided that the weight ratio of dispersed pigment to the sum of all water soluble polyacrylate polymer and polyurethane latex binder is from 3:1 to 1:2. |
