| titleOfInvention | Ink jet inks having improved corrosion resistance |
| abstract | The present disclosure pertains to an aqueous ink jet ink having improved corrosion resistance comprising: (a) a colorant; (b) an aqueous vehicle; and (b) a certain random hydrophilic polymer additive, wherein the random hydrophilic polymer additive comprises a random copolymer comprised of a hydrophilic component and optional hydrophobic component, wherein the hydrophobic component comprises a monomer selected from the group consisting of methyl acrylate, vinyl acetate, and/or a hydrophobic monomer having a carbon to oxygen ratio of at least about 2.5, and wherein the hydrophobic component has a concentration of less than about 40% by weight, based on the weight of the polymer additive, and the hydrophilic component comprises at least one non-acidic hydrophilic monomer having a carbon to oxygen ratio of less than about 2.5, and a monomer with an ionizable acidic group with a carbon to oxygen ratio of less than about 2.5 present in the amount of at least 10%, based on the weight of the polymer additive; and wherein the ratio of colorant to random hydrophilic polymer additive is about 1:1 to about 1:40. |
