Influence of Polymer-Polymer Interactions on Properties of Ink Jet Coatings

摘要

Theoretical and practical aspects of the consequences of polymer-polymer interactions in ink jet receiver coating are discussed. Several examples are presented pertaining to type of modification and charges of polyvinyl alcohol will have an effect on print quality with dye and pigmented inks. It is shown that the introduction of a dye fixative to the coating improves the water fastness but has negative effect on print quality. It was found that the pH adjustments in the ink receiving layers increase the gloss of the media.
