Abstract
Official abstract text for this publication.
A sacrificial coating on an intermediate transfer member of an aqueous ink imaging system is disclosed. The sacrificial coating is made from ingredients comprising: a waxy starch; at least one polycarboxylic acid cross-linking agent; at least one hygroscopic material; and at least one surfactant.
First claim
Opening claim text (preview).
What is claimed is: 1. A sacrificial coating on an intermediate transfer member of an aqueous ink imaging system, the sacrificial coating made from ingredients comprising: a waxy starch; at least one polycarboxylic acid cross-linking agent; at least one hygroscopic material; and at least one surfactant. 2. The sacrificial coating of claim 1 , wherein the waxy starch comprises at least one starch selected from the group consisting of a waxy maize starch, a waxy rice starch, a waxy cassava starch, a waxy potato starch, a waxy wheat starch and a waxy barley starch. 3. The sacrificial coating of claim 1 , wherein the at least one polycarboxylic acid is selected from the group consisting of dicarboxylic acids and tricarboxylic acids. 4. The sacrificial coating of claim 1 , wherein the at least one polycarboxylic acid is citric acid. 5. The sacrificial coating of claim 1 , wherein the at least one polycarboxylic acid is a water soluble polymeric carboxylic acid. 6. The sacrificial coating of claim 1 , wherein the sacrificial coating further comprising at least one polymer selected from the group consisting of i) polyvinyl alcohol and ii) a copolymer of vinyl alcohol and alkene monomers.
