Abstract
A layered intermediate used in inkjet printing contains a release coat formed on a transfer medium in an area where an image has not been printed. The release coat is formed of polyvinyl pyrrolidone (PVP) or a PVP copolymer and at least one solvent selected from the group consisting of glycol solvents and diol solvents. A viscous coating of PVP or the PVP copolymer is formed on the transfer medium in an area where an image has been printed. A release layer formed from components in the release coat and components in the ink is formed on the viscous coating. A first ink layer is formed on the release layer of flocculated ink. A second ink layer is formed on the first ink layer, of ink that is substantially not flocculated.
