Inkjet receiver coatings used in state of the art inkjet media are often constructed as water insoluble hydrogels. Hydrogel coatings formed from the dissolution of a water soluble and water insoluble polymer blend into a common carrier solvent shows a dramatic effect of morphology with the air temperature and drying rate used in the receiver coating drying process. The changes measured in the physical attributes of the inkjet receiver coating are shown to have a pronounced effect on the print quality of a typical inkjet print. Previously, little, if any, work has been published linking important phase structures of inkjet receiver coatings on print and image quality attributes. The author will present a model describing the mechanism of the hydrogel formation process and related information on observed print and image quality.
