Abstract
A fluid set for inkjet printing comprising a fluid having a compound functionalized with at least two functional groups selected from the group consisting of a primary amine and a secondary amine, and an aqueous inkjet ink comprising a colorant and a polymeric particle comprising an oligomer or polymer comprising at least three repeating units functionalized with a functional group selected from the group consisting of a 1,3-diketone, a 0-keto-aldehyde and a 1,3-dialdehyde, with the proviso that the active methylene is functionalized with at least one hydrogen. The fluid is preferably a pre-treatment liquid or over coat liquid.
